Health authorities in Thailand reported 516 new cases of coronavirus on Saturday, by far the biggest one-day jump in a country that had previously brought the epidemic largely under control, according to Reuters.
The new cases were reported in Samut Sakhon province, where an outbreak has been reported linked to a shrimp market.
Opas Karnkawinpong, director general of the disease control department, told a news conference the new cases were found through testing among migrant workers and there were more cases at hospitals.
Most were asymptomatic, he said.

‘Tier 4’ lockdown measures expected in SE England 
Boris Johnson is expected to introduce tier 4 restrictions for London and the south-east of England in his press conference this afternoon, with the planned relaxation of regulations over Christmas scaled back for the rest of the country, writes Molly Blackall.
Tier 4 restrictions may spell an end to Christmas plans, with those living under the new top tier thought to be prevented from meeting other households over the holiday.
There are also suggestions that just two households will now be able to meet in the rest of England, rather than the planned three.
The prime minister will be joined by the chief medical officer for England, Chris Whitty, and the UK’s chief scientific adviser, Patrick Vallance, for a press conference at 4pm on Saturday, following an emergency meeting with cabinet ministers at 1pm.
It comes as cases of coronavirus surge, and concerns grow over a new strain of coronavirus which is spreading rapidly across the south-east of England.

Police are attempting to disperse anti-lockdown protesters who have gathered outside parliament in London.
The Metropolitan police said protesters were gathering in Parliament Square in significant numbers on Saturday afternoon. According to the force, organisers have not submitted a risk assessment for the demonstration.
“This protest is not exempt from the ‘rule of 6’ and should not be happening,” the force said on Twitter.

“I’m going to keep doing this until we’re free,” he said as he was led to a police van.

Prof Chris Whitty, chief medical officer for England, said the UK has informed the World Health Organization that the new coronavirus strain can spread more rapidly.
“As announced on Monday, the UK has identified a new variant of Covid-19 through Public Health England’s genomic surveillance,” he said in a statement.
“As a result of the rapid spread of the new variant, preliminary modelling data and rapidly rising incidence rates in the south-east, the new and emerging respiratory virus threats advisory group (Nervtag) now consider that the new strain can spread more quickly.
“We have alerted the WHO and are continuing to analyse the available data to improve our understanding.
“There is no current evidence to suggest the new strain causes a higher mortality rate or that it affects vaccines and treatments, although urgent work is under way to confirm this. Given this latest development, it is now more vital than ever that the public continue to take action in their area to reduce transmission.”
