(Reuters) – Here’s what you need to know about the coronavirus right now:

Biden rejects Trump claim that vaccine is imminent

U.S. Democratic presidential candidate Joe Biden on Thursday bluntly contradicted President Donald Trump’s suggestion that a coronavirus vaccine may be only weeks away, warning Americans they cannot trust the president’s word.

“The idea that there’s going to be a vaccine and everything’s gonna be fine tomorrow – it’s just not rational,” Biden said during a CNN town hall in Moosic, Pennsylvania.

Trump again said on Wednesday that a vaccine for COVID-19 could be ready for distribution ahead of the Nov. 3 election.

Most health experts, including Robert Redfield, the director of the Centers for Disease Control and Prevention, have said a vaccine will likely not be widely available until mid-2021.

Israel imposes second lockdown

Israel will enter a second nationwide lockdown on Friday at the onset of the Jewish high-holiday season, forcing residents to stay mostly at home amid a resurgence in new coronavirus cases.

The country’s initial lockdown was imposed in late March and eased in May as new cases tapered off, reaching lows in the single digits.

But in the past week, new cases have reached daily highs of over 5,000, and Israeli leaders now acknowledge they lifted measures too soon.

The new lockdown will last three weeks and coincides with the start of the Jewish New Year, Rosh Hashana, traditionally a time for large family gatherings and group prayer.

UK COVID hospital admissions double every eight days

Britain’s health minister said that the novel coronavirus was accelerating across the country, with hospital admissions doubling every eight days, but he refused to say if another national lockdown would be imposed next month.

The United Kingdom has reported the fifth-highest number of deaths from COVID-19 in the world after the United States, Brazil, India and Mexico, according to data collected by Johns Hopkins University of Medicine.

COVID-19 cases started to rise again in Britain in September, with between 3,000 and 4,000 positive tests recorded daily in the last week. More than 10 million people are already in local lockdowns.

China reports highest new cases since Aug. 10

Mainland China reported 32 new COVID-19 cases on Thursday, marking the highest daily increase in more than a month and up sharply from nine cases reported a day earlier.

Although the latest increase still remains well below the peaks seen at the height of the outbreak in China early this year, it is the biggest since Aug. 10 and suggests continued COVID-19 risks stemming from overseas travelers coming into the country as the pandemic rages on in other parts of the world.

The National Health Commission said that all new cases were imported infections. Mainland China has not reported any local COVID-19 infections since mid-August.

Canada’s Ontario clamps down on parties

Canada’s most populous province will clamp down on social gatherings to prevent “reckless careless people” from spreading the coronavirus at illegal parties, Ontario Premier Doug Ford said on Thursday.

His warning came as the nation’s top medical officer said authorities could potentially lose the ability to manage the pandemic.

Indoor social events in Toronto, Canada’s biggest city – along with Ontario’s Peel and Ottawa regions – would be authorized to include no more than 10 people, down from a previous limit of 50, Ford said.

“This is a serious situation, folks. We will throw the book at you if you break the rules,” he told a news conference.
