KINSHASA (Reuters) – The World Health Organization (WHO) confirmed on Sunday a second case of Ebola in Democratic Republic of Congo after an outbreak this week of 17 other suspected cases.

Health officials are trying to trace 125 people thought to be linked to the cases identified in the remote northeastern province of Bas-Uele province in northeastern Congo near the border with Central African Republic, WHO’s Congo spokesman Eugene Kabambi said.

Three people have so far died among the 19 suspected and confirmed cases, he added.

It was not immediately clear how the first victim, a deceased male, caught the virus, although past outbreaks have been linked to contact with infected bush meat such as apes.

The outbreak comes just a year after the end of an epidemic in West Africa killed more than 11,300 people mostly in Guinea, Sierra Leone and Liberia.

However, Congo, whose dense forests contain the River Ebola near where the disease was first detected in 1976, has experienced many outbreaks and has mostly succeeded in containing them without large-scale loss of life.

The GAVI global vaccine alliance said on Friday some 300,000 emergency doses of an Ebola vaccine developed by Merck <MRK.N> could be available in case of a large-scale outbreak and that it stood ready to support the Congo government on the matter.

U.S. suspends aid to Kenyan health ministry over corruption concerns

NAIROBI (Reuters) – The U.S. government has suspended $21 million in direct aid to Kenya’s Ministry of Health amid concern over corruption, the embassy said on Tuesday, giving emphasis to an issue that is a growing liability for the government before August elections.

Support for HIV drugs and other health programs outside the ministry would continue, the embassy said, adding that the United States invests more than $650 million on health in Kenya annually.

“We took this step because of ongoing concern about reports of corruption and weak accounting procedures at the Ministry,” the statement from the embassy said. “We are working with the Ministry on ways to improve accounting and internal controls.”

The announcement adds weight to a rising number of scandals plaguing the government of President Uhuru Kenyatta, who is seeking a second and final five-year term in presidential, parliamentary and local elections on Aug. 8.

The so-called Afya House scandal, named after the building housing the Ministry of Health, was based on an audit report leaked to Kenyan media in October.

The audit showed the ministry could not account for 5 billion Kenyan shillings ($49 million) and funds meant for free maternity care had been diverted, newspapers reported.

Officials at Kenya’s anti-corruption commission did not return calls seeking comment on Tuesday, but the ministry of health issued a statement.

“The ministry has been raising matters raised in the internal audit investigations following the Quality Assurance audit by the National Treasury,” the statement said.

“Other autonomous institutions … are undertaking independent investigations.”

Last year, Kenya’s anti-graft chief told Reuters that a third of its state budget – the equivalent of about $6 billion – was lost to corruption every year.

The government disputed the figure, blaming poor paperwork. In October, Kenyatta infuriated voters by telling them he could not tackle corruption because his “hands were tied”. He criticized the judiciary and other agencies for not doing more about the problem.

Kenyan doctors and nurses say the corruption means that hospitals are often left without basic equipment, from drugs to gloves. Kenyan doctors in public hospitals went on strike from December to March, demanding a pay increase and improved working conditions.

Infant mortality and malaria soar in Venezuela, according to government data

CARACAS (Reuters) – Venezuela’s infant mortality rose 30 percent last year, maternal mortality shot up 65 percent and cases of malaria jumped 76 percent, according to government data, sharp increases reflecting how the country’s deep economic crisis has hammered at citizens’ health.

The statistics, issued on the ministry’s website after nearly two years of data silence from President Nicolas Maduro’s leftist government, also showed a jump in illnesses such as diphtheria and Zika. It was not immediately clear when the ministry posted the data, although local media reported on the statistics on Tuesday.

Recession and currency controls in the oil-exporting South American nation have slashed both local production and imports of foreign goods, and Venezuelans are facing shortages of everything from rice to vaccines. The opposition has organized weeks of protests against Maduro, accusing him of dictatorial rule and calling for elections.

In the health sector, doctors have emigrated in droves and patients have to settle for second-rate treatment or none at all. A leading pharmaceutical association has said roughly 85 percent of medicines are running short. Venezuelans often barter medicine, post pleas on social media, travel to neighboring countries if they can afford it, or line up for hours at pharmacies.

The Health Ministry had stopped releasing figures after July 2015, amid a wider data blackout. It was not clear why it published this latest batch of data.

Its statistics for 2016 showed infant mortality, or death of children aged 0-1, climbed 30.12 percent to 11,466 cases last year. The report cited neonatal sepsis, pneumonia, respiratory distress syndrome, and prematurity as the main causes.

Hospitals often lack basic equipment like incubators, and pregnant women are struggling to eat well, including taking folic acid, factors that can affect a baby’s health.

Maternal mortality, or death while pregnant or within 42 days of the end of a pregnancy, was also up, rising 65.79 percent to 756 deaths, the report said.

The Health Ministry did not respond to a request for further information. Maduro’s government says a coup-mongering elite is hoarding medicines to stoke unrest.

‘TURMOIL’

While Venezuelans are acutely aware of the country’s health issues, the ministry’s statistics bulletin shocked some in the medical community.

“The striking part is turmoil in almost all the categories that this bulletin addresses, with particularly significant increases in the infant and maternal health categories,” said Dr. Julio Castro, an infectious disease specialist and an outspoken critic of the government’s health policies.

Doctors say the health bulletins, meant to be released weekly, should be published in a timely fashion to alert medical practitioners to national trends and threats.

Venezuela, for instance, had controlled diphtheria, a bacterial infection that is fatal in 5 to 10 percent of cases, in the 1990s. Doctors last year sounded the alarm that it had returned, but the government initially said there were no proven cases and admonished those seeking to spread “panic.”

The data now shows diphtheria affected 324 people – up from no cases the previous year.

Diphtheria was once a major global cause of child death but is now increasingly rare thanks to immunizations, and its return showed how vulnerable the country is to health risks.

Reuters documented the case of a 9-year-old girl, Eliannys Vivas, who died of diphtheria earlier this year after being misdiagnosed with asthma, in part because there were no instruments to examine her throat, and shuttled around several run-down hospitals.

(For a story on “Venezuelan girl’s diphtheria death highlights country’s health crisis”, click http://www.reuters.com/article/us-venezuela-health-idUSKBN15P1DA)

There were also 240,613 cases of malaria last year, up 76.4 percent compared with 2015, with most cases of the mosquito-borne disease reported in the rough-and-tumble Bolivar state.

Cases of Zika rose to 59,348 from 71 in 2015, reflecting the spread of the mosquito-borne virus around Latin America last year. There was no data for likely Zika-linked microcephaly, where babies are born with small heads, although doctors say there have been at least several dozen cases.

U.S. Zika vaccine begins second phase of testing

CHICAGO (Reuters) – Researchers have begun the second phase of testing of a Zika vaccine developed by U.S. government scientists in a trial that could yield preliminary results as early as the end of 2017.

Dr. Anthony Fauci, director of the National Institutes of Allergy and Infectious Diseases (NIAID), said on Friday the $100 million trial has already been funded and will proceed, irrespective of the $7 billion in cuts to the National Institutes of Health (NIH) budget proposed by the Trump Administration over the next 18 months.

In a conference call with reporters, Fauci would not comment on the proposed cuts because it is not clear yet what the actual budget will be. Both Democratic and Republican lawmakers oppose cuts to the NIH, which funds 21 institutes, including NIAID.

NIH Director Dr. Francis Collins is scheduled to speak with President Donald Trump later on Friday. “I will certainly be talking to Francis Collins when he returns from the White House,” Fauci said.

Zika typically causes mild symptoms, but when the virus infects a pregnant women, she can pass it to her fetus, causing a variety of birth defects including microcephaly, in which the baby’s head is abnormally small.

Fauci said the current Zika vaccine candidate had cleared preliminary safety hurdles, and would now enter testing for efficacy, which would occur in two phases.

The first phase will continue testing for safety and evaluate the vaccine’s ability to stimulate the immune system to develop antibodies to fight Zika. It will also test different doses to see which works best.

The second phase, set to begin in June, will attempt to determine if the vaccine can actually prevent Zika infection.

Several companies are developing Zika vaccines, including Sanofi SA, GlaxoSmithKline Plc and Takeda Pharmaceuticals.

In the NIAID study, researchers aim to enroll at least 2,490 healthy volunteers in areas with confirmed or potential active transmission of Zika by mosquitoes. These include parts of the continental United States, Puerto Rico, Brazil, Peru, Costa Rica, Panama and Mexico. They will receive either the vaccine, or a placebo, and be followed for two years.

If enough people are exposed to the virus, Fauci said they could get an effectiveness signal as early as the end of this year. The trial is expected to be completed by 2019.

Fauci said the government is already in discussions with pharmaceutical companies that would share the costs of the final stage of testing and handle manufacturing.

Zika is primarily transmitted by mosquitoes, but it can also be transmitted sexually. According to Centers for Disease Control and Prevention, 5,182 people in the continental United States have been infected by Zika either locally or through travel to places where the virus is spreading. Another 38,303 cases have been reported in U.S. territories, including Puerto Rico.

U.S.-UK alliance targets the world’s deadliest superbugs

LONDON (Reuters) – Eleven biotech companies and research teams in Britain and the United States were awarded up to $48 million in funding on Thursday to speed development of new antibiotics powerful enough to take on the world’s deadliest superbugs.

The range of antimicrobial medicines able to kill the growing number of drug-resistant infections is dwindling and health experts warn that within a generation the death toll from such “superbug” infections could reach 10 billion.

Announcing its first funding, a new U.S.-U.K. alliance known as CARB-X, short for Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator, said it would invest an initial $24 million in 11 biotech companies pursing various projects to develop antibiotics and diagnostic. Another $24 million will be given in staged payments over three years as projects progress.

Added to private funds from the companies, the CARB-X funding could lead to an investment of more than $75 million in projects that show success, it said in a statement. Britain’s Wellcome Trust global health charity is committing 125 million pounds ($155.5 million) over five years.

Public health specialists have been warning for years that the world is facing an urgent global health threat from antibiotic-resistant superbug bacteria and that the pipeline of novel therapies to treat them is precariously thin.

Drug-resistant infections kill 700,000 people a year worldwide, and the last new antibiotic class to be approved for market was discovered in 1984.

With CARB-X funds, three of the 11 projects are working on potential new classes of antibiotics, while four are exploring new ways of targeting and killing bacteria.

Tim Jinks, head of drug resistant infection at the Wellcome Trust, said antibiotic resistance is already “a huge global health challenge” and is getting worse. “Without effective drugs, doctors cannot treat patients,” he said in a statement.

Kevin Outterson, CARB-X’s executive director and a professor of law at Boston University in the United States, added: “By accelerating promising research, it is our hope that we can speed up the delivery of new effective antibacterials, vaccines, devices and rapid diagnostics to patients who need them.”

Top U.S. chicken producing state suffers first case of bird flu

By Tom Polansek

CHICAGO (Reuters) – Georgia has confirmed its first-ever case of bird flu in commercial poultry, its agriculture department said on Monday, widening an outbreak of the disease into the United States’ biggest chicken meat-producing state.

A flock of 18,000 chickens used for breeding was culled after testing positive for H7 bird flu, according to the agriculture department. It said the birds in far northwestern Georgia were likely infected with a form of the virus that is not highly lethal because the flock did not show signs of illness.

The discovery came after officials in Alabama, Kentucky and Tennessee confirmed cases of highly pathogenic, or lethal, and low pathogenic H7N9 bird flu in breeding operations this month. U.S. officials have said the risk of the disease spreading to people from poultry or making food unsafe is low.

But the spread of highly pathogenic bird flu to poultry in new states would represent a financial risk for meat companies because it could kill more birds or require flocks to be culled. It could also trigger more import bans from other countries after South Korea and other buyers limited U.S. poultry shipments following highly pathogenic cases in Tennessee.

The worst-ever U.S. outbreak of highly pathogenic bird flu in poultry in 2014 and 2015 killed about 50 million birds, most of which were egg-laying hens in Iowa.

More than 200,000 breeding chickens in Georgia, Alabama, Tennessee and Kentucky have been killed in recent weeks by high and low pathogenic bird flu or culled to contain the virus, according to state officials. U.S. poultry producers had about 55.1 million breeder hens on hand as of March 1, according to the USDA.

In 2015, Georgia produced 7.9 billion pounds of chicken meat valued at $4.2 billion, the agency said.

“Poultry is the top sector of our number one industry, agriculture, and we are committed to protecting the livelihoods of the many farm families that are dependent on it,” Gary Black, Georgia’s agriculture commissioner, said in a statement.

Some companies are still feeling pressure related to the 2015 losses.

On Monday, Cal-Maine Foods, the biggest U.S. egg producer, said its quarterly sales fell about 32 percent from a year ago because prices were under pressure after farmers increased production in response to an outbreak two years ago.

Alabama waits for U.S. verdict on bird flu; importers limit trade

By Tom Polansek

CHICAGO (Reuters) – U.S. trading partners on Friday limited shipments of poultry from Alabama, a top producer of chickens for meat, over bird flu concerns as the state’s wait for federal confirmation of two suspected cases stretched past a week.

The European Union, Kazakhstan and French Polynesia restricted shipments from Alabama counties with presumed cases of the disease, according to the U.S. Department of Agriculture’s website. The moves came a day after the state reported the agency’s national animal-health laboratories had confirmed a separate case of bird flu there.

Belarus blocked shipments from the entire state.

Alabama officials and poultry producers have been waiting since March 8 for the National Veterinary Services Laboratories (NVSL) to confirm the two suspected cases, which involve a commercial chicken farm and a backyard flock, according to the state. The facility in Ames, Iowa, is the only one in the United States that officially confirms cases of avian flu.

Swift confirmation is important for U.S. trading partners, some of which restrict shipments from geographic areas with infected flocks, and for state officials, who want to know which strain of the virus they are battling.

Highly pathogenic, or lethal, bird flu led to the deaths of about 50 million birds, mostly egg-laying hens, in the United States in 2014 and 2015.

Another widespread outbreak could be a financial blow for poultry operators, such as Tyson Foods Inc or Pilgrim’s Pride Corp, because it could kill more birds or require flocks to be culled.

The national labs must determine the strain and pathogenicity of the disease in order to officially confirm an infection, according to the USDA. The process often takes just a day.

A rapid test can be made when poultry samples contain sufficient genetic material, USDA spokeswoman Lyndsay Cole said on Thursday. But the samples from Alabama’s two suspected cases contained low levels, meaning scientists had to start a testing process that can take 14 days, she said.

Tests by a USDA-approved lab in Alabama and the national labs have already identified the H7 subtype of the virus from samples in the two suspected cases, she said.

“Our department respects the science behind the testing and is patiently waiting for accurate results,” said Amy Belcher, spokeswoman for Alabama’s agriculture department.

Alabama authorities presume the suspected cases are not highly lethal, or pathogenic, bird flu because the animals did not show signs of being sick. Still, officials have been checking birds at nearby farms for infections and the owners of the suspect flocks culled the birds, according to Alabama’s state veterinarian.

The United States must alert the World Organisation for Animal Health (OIE) if Alabama’s suspected cases are confirmed as positive, a step that could trigger more trade restrictions.

The OIE said “it is more important for the laboratory to be sure of its analysis than to be fast with it.”

Bird flu hits another U.S. farm that supplies Tyson Foods

quarantine researcher checking chickens on poultry farm for bird flu

By Tom Polansek

CHICAGO (Reuters) – Bird flu that is highly lethal to poultry has infected a second commercial chicken farm in Tennessee that supplies Tyson Foods Inc, company and state officials said on Thursday.

The finding expands an outbreak near the major chicken-producing states of Alabama and Georgia, and is the second in the type of breeder flock crucial for keeping the chicken-meat industry supplied with birds. A case of less dangerous bird flu was confirmed in Alabama on Thursday.

In Tennessee, authorities have started to cull the infected flock of 55,000 chickens in Lincoln County, to contain the highly pathogenic H7N9 flu, according to the U.S. Department of Agriculture.

The farm was in a quarantine zone established after authorities this month found the same strain of the disease in a flock of about 73,500 chickens less than 2 miles (3.2 km) away, the Tennessee Department of Agriculture said. That farm also supplied Tyson, the world’s biggest chicken company.

“I’m sure on the part of the company they’re quite concerned and going back and reviewing all of their information and data to determine how in the world this got into the buildings,” said Bret Marsh, state veterinarian in Indiana, which had the nation’s only highly pathogenic bird flu case in poultry in 2016.

The initial case in Tennessee was the nation’s first infection of highly pathogenic bird flu at a commercial operation in more than a year. Tennessee also recently detected a less-dangerous case of low-pathogenic flu in another chicken flock.

On Thursday, Alabama said the USDA confirmed a suspected case of low-pathogenic flu in a guinea fowl at a flea market as H7N9. Aviagen, the world’s largest poultry breeding company, has culled chickens in the state over concerns about the disease.

Highly pathogenic bird flu led to the deaths of about 50 million birds, mostly egg-laying hens, in the United States in 2014 and 2015.

Another widespread outbreak could represent a financial blow for poultry operators because it could kill more birds or require flocks to be culled. It also would likely trigger more import bans from trading partners, after South Korea, Japan and other countries limited imports after the first highly pathogenic case in Tennessee.

China has also been grappling with an outbreak of H7N9, which has killed 161 people since October. U.S. authorities have said that strain is genetically distinct from the H7N9 in Tennessee and that the risk of the disease spreading to people from poultry or making food unsafe is low.

Tyson said it worked with Tennessee and federal officials to quickly euthanize birds in the infected flock and did not expect disruptions to its chicken supply.

“Our business is diversified and scaled across multiple states, so we plan to meet our customers’ needs,” spokesman Worth Sparkman said.

Tyson shares fell 1.7 percent to close at $62.00 on Thursday.

The company has said it tests all the birds it owns for the virus and flocks diagnosed with highly pathogenic flu are not processed.

Wild birds can carry the disease without showing signs of sickness and transmit it to poultry through feces, feathers or other forms of contract.

Poultry breeder Aviagen culls U.S. flock over bird flu fears

By Tom Polansek

CHICAGO (Reuters) – Aviagen [EWESJA.UL], the world’s leading poultry breeding company, has euthanized chickens at a farm in Alabama over concerns about bird flu, the company said on Tuesday, as likely cases of the disease emerged in a top chicken-producing state.

Alabama officials said they suspected that poultry at three sites in the state were infected with the virus, about a week after some 90,500 chickens were culled over infections at two commercial operations across the border in Tennessee.

Aviagen detected the presence of antibodies for the flu virus in a flock in Alabama that showed “no evidence of clinical disease,” company spokeswoman Marla Robinson said in an email. The company is based in Alabama.

The company euthanized the flock and “all eggs which were collected from that farm in the production system were traced and removed,” she said. Aviagen did not respond to a question about how many birds were killed.

Tony Frazier, Alabama’s state veterinarian, said the company chose to cull about 15,000 birds. The U.S. Department of Agriculture (USDA) said the farm had 153,000 birds.

A national USDA lab is testing samples from poultry in Alabama to identify the strain of the virus and how lethal it is for birds, after another agency-approved lab identified the H7 subtype of the disease in samples, USDA spokeswoman Lyndsay Cole said.

The birds in Alabama did not show clinical signs of sickness, which indicates they did not have a highly lethal, or pathogenic, form of the virus, Cole said.

In Tennessee, both cases were identified as H7N9. The USDA on March 5 confirmed that one was the United States’ first infection of highly pathogenic flu in commercial poultry in a year. Days later, the state said it had found the other case nearby and it was low pathogenic.

Highly pathogenic bird flu led to the deaths of about 50 million birds, mostly egg-laying hens, in the United States in 2014 and 2015.

Another highly pathogenic outbreak would likely represent a financial blow for poultry operators such as Tyson Foods Inc and Pilgrim’s Pride Corp because it would kill more birds or require flocks to be culled.

It also would likely trigger more import bans from trading partners, after South Korea, Japan and other countries limited imports after the highly pathogenic case in Tennessee.

Health officials have said the risk of bird flu spreading to people from poultry or making food unsafe was low.

Separately, Frazier said the owner of a backyard flock suspected of having the virus chose to cull about 70 birds. No poultry linked to the third suspected case, which involved birds at a flea market, have been culled, he said.

Frazier said the cases were still only suspected flu infections and needed to be confirmed by the USDA. Earlier, the Alabama Department of Agriculture and Industries called a news conference to discuss what it said were three findings of avian influenza.

Alabama raised more than 1 billion chickens for meat in 2015, making it the country’s third largest producer, according to the USDA.

The national USDA laboratory, to which samples from the state were sent, is the only one in the United States that officially confirms cases.

The World Organization for Animal Health requires that all confirmed low-pathogenic H5 and H7 bird flu subtypes be reported because of their potential to mutate into highly pathogenic strains. Highly pathogenic cases also must be reported.

Bird flu infects Alabama poultry, likely low pathogenic -officials

By Tom Polansek

CHICAGO (Reuters) – Bird flu has infected poultry at three sites in northern Alabama shortly after being found at two farms in neighboring Tennessee, and more chickens have been culled to contain the virus, state and industry officials in Alabama said on Tuesday.

The cases in Alabama are suspected to be the less dangerous form of the disease, known as low pathogenic, because the infected flocks did not have high levels of mortality, said Ray Hilburn, associate director of the Alabama Poultry and Egg Association, an industry group.

The flocks were near the spot in southern Tennessee where the U.S. Department of Agriculture confirmed on March 5 the nation’s first case of highly pathogenic flu in commercial poultry in more than a year. Days later, Tennessee said it had detected low-pathogenic flu at another chicken farm nearby.

Highly pathogenic bird flu is often fatal for domesticated poultry and led to the deaths of about 50 million birds, mostly egg-laying hens, in the United States in 2014 and 2015. The less-serious low pathogenic flu form can cause coughing, depression and other symptoms in birds.

The spread of highly pathogenic flu could represent a financial blow for poultry operators such as Tyson Foods Inc and Pilgrim’s Pride Corp because it would kill more birds or require flocks to be culled. It also would trigger more import bans from other countries, after South Korea, Japan and other nations limited imports following the highly pathogenic case in Tennessee.

Alabama has not received any definitive test results that show its cases are highly pathogenic, said Amy Belcher, spokeswoman for the Alabama Department of Agriculture and Industries. No epidemiological connections have been made between the cases in Tennessee and Alabama, she added.

Belcher declined to discuss culling of the birds ahead of a news conference on bird flu, or avian influenza (AI), in the state on Tuesday.

Hilburn said infected birds had been culled but did not know how many. He said one case in Alabama was at a commercial breeding facility for chickens raised for meat and one involved a backyard flock.

“As soon as they find out that its possibly any type of AI, they’re going to get rid of the birds,” Hilburn said. “They don’t take a chance on anything.”

Health officials have said the risk of bird flu spreading to people from poultry or making food unsafe was low.
