U.S. fights Zika mosquitoes with limited arsenal

Zika virus kit

By Julie Steenhuysen

(Reuters) – Over Wynwood, the Miami neighborhood where Zika gained a foothold in the continental United States, low flying planes have been spraying naled, a tightly controlled pesticide often used as a last resort. It appears to be working, killing at least 90 percent of the target mosquitoes.

Across the Biscayne Bay in Miami Beach, wind and high-rise buildings make aerial spraying challenging. So, the effort in the popular tourist destination has focused on ground-sprayed pyrethroids – pesticides that are safer but don’t always work.

The arrival in Florida of Zika, a virus that can cause a crippling birth defect known as microcephaly, has drawn into focus the limitations of the U.S. mosquito control arsenal.

Larvicides reduce future populations relatively safely. But for use against the mature mosquitoes that spread disease, only two classes of pesticides are approved. Each has drawbacks.

Organophosphates, such as naled, are effective. But there are strict controls to limit risk. Pyrethroids are safer but have been used so much that mosquitoes, in many places, are immune.

“That’s really the weak link in much of the United States,” said Michael Doyle, director of the Florida Keys Mosquito Control District. “We’re kind of caught off guard.”

DENGUE PREVIEW

Doyle led a 2009 effort against a dengue outbreak in South Florida, the first in the United States in nearly a century. Authorities threw everything they had at the Aedes aegypti, the same mosquito that carries Zika: backpack fogging, door-to-door yard inspections looking for watery breeding sites and larvicide spraying.

Still, 88 people were infected before the virus was brought under control more than two years later, and there continue to be sporadic cases in Florida.

The outbreak highlighted gaps in the mosquito control arsenal that remain, according to pesticide makers, abatement officials and entomologists. Few companies make pesticides for use in public health outbreaks, a niche market that is expensive to get into, has a limited upside and varies season to season.

Safety testing a new pesticide can cost up to $250 million and take 10 years, said Karen Larson, vice president of regulatory affairs at privately held Clarke Mosquito.

As long as a product remains on the market, companies must continue testing for unforeseen side effects, an expense that some makers have blamed for decisions to abandon products.

“There’s not a lot of profit,” Larson said.

Sales of the Dibrome brand of naled have been estimated at $12 million a year. By comparison, total crop pesticide sales for some companies can exceed $500 million in a single quarter.

Bayer, Dow Chemical, BASF and other agricultural pesticide makers “are not interested in going after a $20 million or $30 million a year market,” said William A. Kuser, investor relations director at Dibrome maker American Vanguard Corp.

The U.S. Environmental Protection Agency has approved several new pesticides in recent years. But it has received few requests for using them against mosquitoes, said Jim Jones, Assistant Administrator for the agency’s Office of Chemical Safety and Pollution Prevention.

“Although it’s of critical importance, the amount one can sell is small and it’s variable, which makes it difficult for business planning,” Jones said. “You can go many years without having much of a market at all, then suddenly, whether it’s because of a nuisance outbreak of mosquitoes or something like West Nile or Zika, the market grows significantly.”

Abatement authorities have pressed for help with the cost of developing mosquito control pesticides. The 1996 U.S. Food Quality Protection Act includes a provision for subsidies to defray the expense of safety testing, but Congress has never funded it.

RISK AND RESISTANCE

At least 49 cases of locally transmitted Zika infections have been reported in Florida, most in Wynwood and Miami Beach. Most people have no symptoms or mild illness.

Because of the microcephaly link, efforts are focused on preventing infection among pregnant women.

In Wynwood, the campaign began with pyrethroids, synthetic versions of a chemical derived from chrysanthemums. Amid signs of resistance, authorities switched to naled.

Developed as nerve agents, organophosphates, at high doses, can cause nausea, convulsions and death. They can be toxic to wildlife, including bees. The EPA considers naled safe at permitted ultra-low concentrations, and it is sprayed annually over 16 million acres in the United States.

But it is banned in Europe, where the risk is seen as unacceptable. In the U.S. territory of Puerto Rico, where Zika is widespread, the governor prohibited naled amid protests over safety concerns.

Although naled killed more than 90 percent of mosquitoes in traps set in Wynwood, the Aedes aegypti’s resilience remains a concern.

“This is truly the cockroach of mosquitoes,” said Tom Frieden, director of the U.S. Centers for Disease Control and Prevention.

DROPPING PESTICIDES

CDC entomologist Janet McAllister said pyrethroid resistance typically is limited by the mosquito’s small range. When resistance to one pyrethroid develops, another often works.

Still, she said, “we would love to see additional classes of insecticides available because, even in places that may have an effective tool today, that doesn’t mean it is going to last down the road.”

The EPA can fast-track its evaluation of new pesticides and expand the use of old ones. In response to Zika, it expedited new uses for pesticide-treated bed nets and mosquito traps.

Still, development of pesticides is painstaking. Even if the EPA speeds up its evaluation, required safety data can take years to collect. And the expense of ongoing safety testing has prompted companies to drop products.

Bayer CropScience, for example, told distributors it dropped the pyrethroid resmethrin in 2012, rather than do additional testing. Clarke Mosquito gave up temephos, a larvicide, six years ago, because of costs, Larson said.

That decision led to stockpiling in southwest Florida, said Wayne Gale, director of the Lee County Mosquito Control District.

“We purchased just about every bit,” he said.

China steps up arrival checks from Singapore amid ZIKA outreach

By Aradhana Aravindan and Ben Blanchard

SINGAPORE/BEIJING (Reuters) – China intensified its checks on people and goods arriving from Singapore on Thursday, as an outbreak of the Zika virus in the small city-state was confirmed to have spread to at least one person in neighboring Malaysia.

Singapore is the only Asian country with an active transmission of the mosquito-borne Zika virus, which is a particular risk to pregnant women, according to the U.S. Centers for Disease Control and Prevention.

Authorities in Singapore, a leading regional financial center and busy transit hub for people and cargo, reported the first locally-transmitted Zika infection on Saturday, with the number of cases rising to 115 by Thursday – half of whom were foreigners, mainly from China, India and Bangladesh.

Malaysia confirmed its first case of Zika infection, in a woman who had recently visited Singapore.

“We have been tracking Zika for a while now, and knew it was only a matter of time before it reached Singapore,” Singapore Prime Minister Lee Hsien Loong posted on his Facebook page. “Our best defense is to eradicate mosquitoes and destroy breeding habitats, all over Singapore.”

The United States, Australia and other countries have warned pregnant women or those trying to conceive not to travel to Singapore.

The outbreak and travel warnings come just two weeks before the Singapore F1 motor-racing Grand Prix, a major sporting and tourist draw. Race promoter Singapore GP has said planning for the event is going ahead “as per normal”.

Singapore’s Tourism Board has said it is premature to consider any impact on the tourism industry, stressing the tropical city-state remains a “safe travel destination”.

More than 55 million people pass through Singapore’s Changi airport each year. Tourism arrivals topped 8 million in the first half of this year, around 1 million more than a year ago.

“NEGATIVE IMPACT”

China is trade-dependent Singapore’s top overseas market, and the Zika outbreak coincides with a dip in overall exports and slowing economic growth in both countries.

“If this continues, certainly it will have a negative impact, but it’s hard to quantify in percentage terms or dollar value,” said Francis Tan, an economist at United Overseas Bank in Singapore.

The Zika virus, which has spread through the Americas and the Caribbean since late last year, is generally a mild disease but has been linked to microcephaly – a severe birth defect in which babies are born with abnormally small heads and underdeveloped brains.

The World Health Organization, which has declared Zika an international public health emergency, is holding a regular meeting of its Zika emergency committee on Thursday to review the spread of the disease.

Singapore authorities said late on Wednesday they found some new Zika cases beyond the cluster area where it had initially been detected. They also confirmed a first Zika case in a pregnant woman in the country.

On Thursday, Singapore said half of the cases found so far involved foreigners – including 23 Chinese nationals, 15 Indians and 10 Bangladeshis – adding that most patients had recovered. Many of the foreigners are believed to be among the hundreds of thousands of migrant workers who work in Singapore’s construction and marine industries.

Malaysia, which has two land border crossings with Singapore, asked those going to the city-state to use mosquito repellent and to cover up to avoid bites. Tens of thousands of people travel between the two countries daily.

Indonesia has also stepped up protective measures following the Singapore outbreak, intensifying checks on arrivals from Singapore, introducing thermal scanners and posting paramedics at airports and border checkpoints.

Zika is carried by mosquitoes, which transmit the virus to humans, though a small number of cases of sexual transmission of the virus have been reported in the Americas. A case of suspected transmission through a blood transfusion in Brazil has raised questions about other ways in which Zika may spread.

There is no vaccine or treatment for Zika, which is a close cousin of dengue and chikungunya and causes mild fever, rash and red eyes. An estimated 80 percent of people infected have no symptoms, however. The WHO has also linked Zika to Guillain-Barre, a rare neurological syndrome that causes temporary paralysis in adults.

Zika virus findings show hearing loss to some babies

CHICAGO (Reuters) – A study in Brazil of 70 babies whose mothers had confirmed Zika infections found that nearly 6 percent had hearing loss, adding a new complication to the list of ills the virus can cause when women are infected during pregnancy.

The Brazilian study, published on Tuesday in the U.S. Centers for Disease Control and Prevention’s weekly report on death and disease, confirmed less rigorous reports of deafness among infants born to mothers with Zika infections.

The finding is part of an effort to fully characterize the harm caused by the Zika virus during pregnancy. The virus is best known for causing the severe birth defect microcephaly, characterized by undersized heads and underdeveloped brains. But other studies have shown that Zika can cause other brain abnormalities, vision problems and joint deformities.

In the latest study, a team led by Dr. Marli Tenório and Dr. Ernesto Marques of the Oswaldo Cruz Foundation in Pernambuco, Brazil, examined records from 70 infants with microcephaly whose mothers had laboratory-confirmed Zika infections during pregnancy.

They found that nearly 6 percent had hearing loss without any other plausible cause.

Several other viral infections during pregnancy can cause hearing loss, including rubella and cytomegalovirus, or CMV, infections. The current study adds Zika infection to that list.

Scientists say Zika should now be considered a risk factor for hearing loss, and children who were exposed during pregnancy but have normal hearing at birth should be screened regularly for delayed or progressive hearing loss.

The connection between Zika and microcephaly first came to light last fall in Brazil, which has since confirmed more than 1,800 cases of microcephaly.

Singapore confirms 41 cases locally transmitted ZIKA virus

Contractor fogs a condominium garden in Singapore in an effort to kill mosquitoes

By Marius Zaharia

SINGAPORE (Reuters) – Singapore has confirmed 41 cases of locally transmitted ZIKA virus, mostly among foreign construction workers, and said it expected more cases to be identified.

All but seven of those infected had fully recovered, the Health Ministry and the National Environment Agency said in a statement on Sunday. The seven remain in hospital.

On Saturday, authorities confirmed a 47-year-old Malaysian woman living in southeastern Singapore as the city-state’s first case of a local transmission of the virus.

Zika, carried by some mosquitoes, was detected in Brazil last year and has since spread across the Americas. The virus poses a risk to pregnant women because it can cause severe birth defects. It has been linked in Brazil to more than 1,600 cases of microcephaly, where babies are born with small heads.

Singaporean authorities said they tested 124 people, primarily foreign construction workers employed on a site in the same part of Singapore. That site has been ordered to halt work, and workers’ dormitories are being inspected. Seventy-eight people tested negative and five cases were pending. Thirty-four patients had fully recovered.

Four Singaporean men had developed symptoms of the virus in the past week and were hospitalized on Saturday. It was not clear where the foreign workers were from or when their cases were detected. Singapore hosts a large contingent of workers from the Asian subcontinent.

None of those infected had traveled recently to Zika-affected areas. “This confirms that local transmission of Zika virus infection has taken place,” the statement said.

The ministry “cannot rule out further community transmission since some of those tested positive also live or work in other parts of Singapore,” the statement said. “We expect to identify more positive cases.”

The World Health Organization said in a statement on Sunday that it did not know “which lineage of Zika is circulating” or “what the level of population immunity is to this lineage of Zika in Asia.”

“It is important for countries to remain vigilant through surveillance for cases, to continue vector control, to inform people about Zika and how they can protect themselves, and to have the health system ready to supply the services needed to prevent and manage Zika and its consequences,” the group told Reuters.

Singapore, a major regional financial center and busy transit hub, which maintains a constant vigil against the mosquito-borne dengue virus, reported its first case of the Zika virus in May, brought in by a middle-aged man who had been to Brazil.

CLEANUP

Singapore deployed about 200 NEA officers to clean drains and spray insecticide in the mainly residential area early on Sunday to counter mosquito breeding grounds, and volunteers and contractors handed out leaflets and insect repellent.

All medical services in Singapore had been alerted “to be extra vigilant” and immediately report any Zika-associated symptoms to the health ministry.

Singapore said there were “ongoing local transmission” cases in Indonesia, Thailand and Vietnam. Other countries in the region to have detected the Zika virus since 2013 include Bangladesh, Cambodia, Laos, Malaysia, Maldives and the Philippines, according to the WHO.

Malaysia said on Sunday it stepped up surveillance at main transit points with Singapore – handing out leaflets on Zika prevention and having paramedics ready to handle visitors with potential symptoms of the virus.

In Thailand, where close to 100 cases of Zika have been recorded across 10 provinces this year, the Department of Disease Control was screening athletes returning from the Olympic Games in Brazil, but was not otherwise changing its prevention measures.

“Every country in this region has Zika transmission cases,” said Prasert Thongcharoen, an adviser to the DDC. “Thailand has, however, managed to contain the problem through early detection.”

A Foreign Ministry spokesman said Indonesia was “following developments”. Oskar Pribadi, a Health Ministry official, said there had been no recent Zika cases in the country.

Vietnam has to date reported three cases of locally transmitted Zika infection.

The current strain of Zika sweeping through Latin America and the Caribbean originated in Asia, where people may have built up greater immunity.

FDA recommends Zika testing for all blood donated in U.S.

An edes aegypti mosquito is seen inside a test tube as part of a research on preventing the spread of the Zika

(Reuters) – The U.S. Food and Drug Administration recommended on Friday that all blood donated in the United States and its territories be tested for Zika virus, as it moves to prevent transmission of the virus through the blood supply.

The agency’s move to expand its previous guideline for blood screening comes after Florida officials on Tuesday announced the first case of Zika transmitted by mosquitoes in Pinellas County, some 265 miles from Miami, where the first locally transmitted U.S. cases were reported.

The FDA last month ordered blood banks in Florida’s two most densely populated counties – Miami-Dade County and Broward County – to stop collecting blood.

The FDA also recommended that nearby counties implement the same measures.

Zika was detected in Brazil last year and has since spread across the Americas. The virus poses a risk to pregnant women because it can cause severe birth defects. It has been linked to more than 1,800 cases of microcephaly in Brazil.

Health officials warned pregnant women last week not to travel to Miami Beach after Florida confirmed the mosquito-borne Zika virus was active there.

The agency had recommended in February that blood should no longer be collected from regions where the Zika virus is circulating, and that blood needed for transfusions be obtained from areas of the country without active transmission.

The FDA has authorized the emergency use of several investigational Zika screening tests, including products made by Hologic Inc <HOLX.O> and Roche Holding AG <ROG.S>.

Health official warns Zika virus could spread across U.S. Gulf

The New York State Department of Health unveiled a Zika Prevention Kit for pregnant women during the rollout of a Zika Information hotline and

By Chris Prentice

(Reuters) – One of the top U.S. public health officials on Sunday warned that the mosquito-borne Zika virus could extend its reach across the U.S. Gulf Coast after officials last week confirmed it as active in the popular tourist destination of Miami Beach.

The possibility of transmission in Gulf States such as Louisiana and Texas will likely fuel concerns that the virus, which has been shown to cause the severe birth defect known as microcephaly, could spread across the continental United States, even though officials have played down such an outcome.

Concern has mounted since confirmation that Zika has expanded into a second region of the tourist hub of Miami-Dade County in Florida. Miami’s Wynwood arts neighborhood last month became the site of the first locally transmitted cases of Zika in the continental United States.

“It would not be surprising we would see additional cases perhaps in other Gulf Coast states,” Dr. Anthony Fauci, director of the allergy and infectious diseases unit of the National Institutes of Health (NIH), said in an interview on Sunday morning with ABC News.

Fauci noted that record flooding this month in Louisiana – which has killed at least 13 people and damaged some 60,000 homes damaged – has boosted the likelihood Zika will spread into that state.

“There’s going to be a lot of problems getting rid of standing water” that could stymie the mosquito control efforts that are the best way to control Zika’s spread, he said.

U.S. health officials have concluded that Zika infections in pregnant women can cause microcephaly, a birth defect marked by small head size that can lead to severe developmental problems in babies. The connection between Zika and microcephaly first came to light last fall in Brazil, which has now confirmed 1,835 cases of microcephaly that it considers to be related to Zika infections in the mothers.

On Friday, Florida Governor Rick Scott confirmed that state health officials had identified five cases of Zika believed to be contracted in Miami Beach.

The U.S. Centers for Disease Control and Prevention told pregnant women they should avoid the trendy area and suggested those especially worried about exposure might consider avoiding all of Miami-Dade County.

NIH’s Fauci on Sunday said the conditions of most of the country make it unlikely there would be a “diffuse, broad outbreak,” even though officials need to prepare for that possibility.

He compared it with diseases such as Dengue, which is endemic in certain tropical and subtropical regions of the world but rarely occurs in the continental United States. In Miami’s Wynwood area, experts have seen “substantial” knockdowns of mosquito populations.

Still, its containment is more complicated because Zika can be sexually transmitted, Fauci said.

“This is something that could hang around for a year or two,” he said.

The World Health Organization has said there is strong scientific consensus that Zika can also cause Guillain-Barre, a rare neurological syndrome that causes temporary paralysis in adults.

Study in mice shows Zika virus also attacks adult brain cells

Aedes aegypti mosquitoes are seen inside Oxitec laboratory in Campinas, Brazil,

By Julie Steenhuysen

CHICAGO (Reuters) – U.S. researchers have found that Zika can attack special populations of brain cells in adult mice in the part of the brain involved in learning and memory, raising new questions about how the virus may be impacting millions of adults who have been infected with the virus.

The findings, published on Thursday in the journal “Cell Stem Cell,” are the first to look at whether Zika can attack the same kinds of cells in adult mice that they do in fetal mice.

Experts cautioned that the findings are preliminary and may not have any correlation to how Zika impacts human brain function, but they suggest the need for follow-up research.

“This is one potential consequence we need to look at,” said Dr. Joseph Gleeson, an expert in pediatric brain disease at The Rockefeller University in New York, who led the study.

Zika has already been shown to attack fetal brain cells known as neural progenitor cells – a type of stem cell that gives rise to various kinds of brain cells. The death of these cells is what disrupts brain development and leads to the severe birth defects seen in babies whose mothers were infected with Zika during pregnancy.

U.S. health officials have concluded that Zika infections in pregnant women can cause microcephaly, a birth defect marked by small head size that can lead to severe developmental problems in babies.

The connection between Zika and microcephaly first came to light last fall in Brazil, which has now confirmed more than 1,600 cases of microcephaly that it considers to be related to Zika infections in the mothers.

Fetal brains are chock full of neural progenitor cells, which are responsible for making cells that form key brain structures. Adults, whose brains are fully formed, have far fewer and there are some pockets remaining – including in the hippocampus, a part of the brain involved in memory and learning.

Gleeson wanted to see if Zika could attack these cells in adult mice. To find out, his team injected the virus into lab mice and examined their brains for Zika infection.

In the hippocampus, Gleeson said “it lit up like a Christmas tree and wiped out the stem cell population.”

“Based on our findings, getting infected with Zika as an adult may not be as innocuous as people think,” he said.

There have already been signs that Zika affects adult nerve cells. Several teams have published papers showing that in some patients, Zika can cause serious brain and spinal cord infections – including encephalitis, meningitis and myelitis – in people exposed to Zika.

In rare cases, Zika has also been linked with Guillain-Barre Syndrome, a post-infectious autoimmune disorder that can cause temporary paralysis in adults.

“It’s really unclear if this translates to human Zika infections,” said Dr. Daniel Pastula, a neurologist and medical epidemiologist at the University of Colorado Denver.

But if it does, it is not clear whether the effect is temporary or lasting.

“Detailed neurological studies are needed in infected humans to describe the effects of Zika virus infection on the brains of adults,” said Dr. Anna Checkley of the Hospital for Tropical Diseases, part of University College London Hospitals.

Gleeson said the study needs to be replicated by other scientists, and he wants to test other strains of Zika on adult mice at other times during an infection to see if those viruses have the same effect.

Since 2015, 66 countries and territories have reported evidence of vector-borne Zika virus transmission, according to the World Health Organization.

Earlier this month, researchers at Notre Dame University estimated as many as 93 million people across Latin America and the Caribbean could become infected with Zika in the current outbreak.

Haiti finds case of microcephaly linked to Zika virus

Public Health guy for Haiti

By Makini Brice

PORT-AU-PRINCE (Reuters) – Haiti has identified its first case of the birth defect microcephaly linked to the Zika virus, a senior health ministry official said on Tuesday.

Gabriel Thimothe, director general at the ministry of public health and population, said the case was confirmed on Saturday by the U.S. Centers for Disease Control and Prevention (CDC).

Haiti has confirmed 14 cases of the birth defect since March, up from previous reports of two cases, Raymond Grand Pierre, the director of the Department of Health and Family in the Ministry of Health, said.

In the other 13 cases, authorities have not established a link to microcephaly although the number may indicate Zika is more widespread in Haiti than previously thought.

According to a chart provided by the Centers for Disease Control, Haiti has recorded nearly 3,000 Zika cases.

But the World Health Organization says the overwhelming majority of cases of the virus in the island nation are suspected and not confirmed.

Thimothe said the baby with Zika-linked microcephaly was born in the city of Mirebalais earlier this summer.

Boston-based Partners in Health and its sister organization, Haiti-based Zanmi Lasante, said in a statement on Aug. 9 that two babies had been born with microcephaly in their University Hospital Mirebalais.

U.S. health officials have concluded that Zika infections in pregnant women can cause microcephaly. The World Health Organization has said there is strong scientific consensus that Zika can also cause Guillain-Barre, a rare neurological syndrome that causes temporary paralysis.

The connection between Zika and microcephaly first came to light last fall in Brazil, which has now confirmed more than 1,600 cases of microcephaly that it considers to be related to Zika infections in the mothers.

Haiti’s healthcare system is still suffering from the fallout of the 2010 earthquake that killed about 300,000 people and a still-ongoing cholera epidemic that began shortly afterward, killing about 8,600 people and infecting 707,000.

Health facilities were also paralyzed this year by a months-long strike by medical residents over pay and working conditions, which Thimothe said had largely ended.

U.S. government shifts $81 million to Zika vaccine research

Zika prevention kit for pregnant women

By Julie Steenhuysen and Toni Clarke

CHICAGO/WASHINGTON (Reuters) – The U.S. Department of Health and Human Services has shifted $81 million in funds from other projects to continue work on developing vaccines to fight Zika in the absence of any funding from U.S. lawmakers.

In a letter addressed to Nancy Pelosi, a Democrat and minority leader of the U.S. House of Representatives, HHS Secretary Sylvia Burwell said she was allocating $34 million in funding to the National Institutes of Health and $47 million to the Biomedical Advanced Research and Development Authority (BARDA) to work on Zika vaccines.

Burwell said the funding was intended to keep Zika vaccine research going despite the lack of funding from U.S. lawmakers, who left for summer recess before allocating any funding to Zika research and preparedness.

The mosquito-borne Zika virus has spread to more than 50 countries and territories since the outbreak began last year in Brazil. On Thursday, Governor Rick Scott said state health officials have identified three additional people in the affected area with locally transmitted Zika, bringing the total to 25.

The Obama administration in February requested $1.9 billion to fight Zika, but congressional lawmakers have been considering a much smaller sum. A bill providing $1.1 billion was blocked by Democrats after Republicans attached language to stop abortion-provider Planned Parenthood from using that government funding for healthcare services, mainly in U.S. territories like Puerto Rico.

The Republican legislation also would siphon off unused money under President Barack Obama’s signature 2010 healthcare law to combat Zika. In addition, Democrats balked at a Republican provision that they said would gut clean water protections.

The new bolus of funds from HHS comes on top of the $589 million in repurposed funds previously allocated for Ebola efforts. HHS has said these funds will run out at the end of August.

At a press briefing in Washington, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said he needs $33 million to prepare to move the first potential Zika vaccine to the second phase of human clinical trials. The first phase of that testing is expected to end in late November or December.

Fauci said the health secretary has the authority to transfer 1 percent of NIH’s $33 billion budget per year from one Institute to the other. He said the director of the NIH, Dr. Francis Collins, will decide which existing programs the funds will be drawn from.

“He will probably do it on a prorated basis across the Institutes,” he said.

Fauci said the budget transfer will not fill the longer-term NIH funding needs to fight the virus and to develop a second or third potential vaccine candidate. Drugs frequently fail to realize the promise they show in early trials.

“We still need about $196 million more,” he said.

Fauci said the health secretary’s action was essentially one of desperation given the failure of Congress to authorize additional funding.

Taking money from other research programs “is extremely damaging to the biomedical research enterprise,” he said. “We’re taking money away from cancer, diabetes, all those things.”

Dr. LaMar Hasbrouck, executive director of the National Association of County and City Health Officials, said at the briefing that local health authorities are similarly siphoning off money from other programs.

“We’re robbing Peter to pay Paul,” he said.

In her letter, Burwell said the $47 million in funding for BARDA will allow the agency to enter into contracts with key partners to develop vaccines. But, she said BARDA will need an estimated $342 million in additional funding to continue its work with outside partners in the development of vaccines, diagnostics and pathogen inactivation technology used to protect the U.S. blood supply.

Florida is investigating apparent new case of locally transmitted Zika

Florida Gov. Rick Scott speaks at a press conference about the Zika virus in Doral, Florida, U.S. on August 4, 2016.

By Julie Steenhuysen

(Reuters) – Florida health officials are investigating a new non-travel- related case of Zika virus in Palm Beach County, but it is not yet clear whether the person contracted the virus from local mosquitoes or from a recent trip to Miami.

Governor Rick Scott said in a statement on Monday that the infected person recently traveled to Miami-Dade County, which is experiencing an outbreak of Zika caused by local mosquito transmission. So far, 16 people have been infected in the Miami area. The Palm Beach case brings the state’s tally to 17.

An investigation was under way to determine how the person in Palm Beach County became infected.

The governor said the state still believed active transmission of the virus were confined to a one-square-mile (260-hectare) area in Miami-Dade County that includes Miami’s Wynwood district.

The U.S. Centers for Disease Control and Prevention is warning pregnant women to avoid this area in Miami because Zika has been tied to birth defects, including microcephaly, which can case severe developmental problems.

With the school year approaching, Scott said he had ordered the department of health to work with the state’s department of education “to ensure students, parents, educators and district leaders have all the resources and guidance they need to combat the Zika virus.”

The continuing Zika outbreak was first detected last year in Brazil, where it has been linked to more than 1,700 cases of the microcephaly, and has since spread rapidly through the Americas. Its arrival in the continental United States has been widely anticipated.
