New York State runs about 1,000 genome tests every week to look for new, contagious variants of Covid, said state health commissioner Dr. Howard Zucker, at a news conference on Friday.

“The new varieties are terrifying: the British variety, the Brazilian variety, now the South African variety,” said Governor Andrew Cuomo at the briefing. “The British variety is here.”

Zucker said the state has done about 6,000 genome tests so far and only found the strain that came from the UK. New York officials have so far identified 25 of these cases, including two new cases in Westchester County and one new case in Kings County. Said Cuomo. According to Zucker, there were no deaths in these cases.

British Prime Minister Boris Johnson told reporters on Friday that there was “some evidence” of the mutated tribe could also be more deadly than the originalwhich has its origin in Wuhan, China.

The Centers for Disease Control and Prevention previously said there was no evidence that any of the new variants were more deadly or causing more serious illness.

When asked about the potential for higher mortality associated with the British tribe, Zucker said he was in contact with the British science advisor and the evidence is still preliminary.

“The fact that it’s more communicable means there will be more cases. If there are more cases, there will be more hospitalizations, and obviously if there are more hospitalizations there is an obvious risk of more deaths,” Zucker said.

At the meeting, Cuomo said he hoped President Joe Bidens The new administration will boost vaccine production and allow increased vaccine distribution. New York gave more than 975,000 people at least one dose of the vaccine on Thursday, according to the state Vaccine tracker.

“The British tribe is spreading. We still only have a vaccination rate of 60% to 70% of our hospital workers. This is a problem,” said Cuomo.
