Ashish Jha explains why he is concerned about the spread of the UK variant

Dr. Ashish Jha said on Monday that the United States is “on the road to recovery” from COVID-19, but there are still some “bumps”.

One of the biggest is the virus variant first detected in the UK, B.1.1.7, which spreads easier and faster than other strains.

To date, 690 cases of the variant have been detected in the United States, according to the Centers for Disease Control and Prevention, which warned B.1.1.7 could become the dominant source of coronavirus infections in the country in March. Seven cases have been confirmed so far in Massachusetts, according to the CDC.

Jha, dean of the Brown University School of Public Health, said on Monday that the United States is seeing positive trends, including falling rates of infection and hospitalizations. He also expects vaccines to be “plentiful” in late spring.

“I am optimistic about the end of spring and summer,” wrote Jha on Twitter. “But worried about the coming months.”

The doctor pointed out data from Ireland and Germany that illustrate how B.1.1.7 can “quickly oppress a nation”. Ireland, he noted, used a blockade to control infections in October. But as the UK variant started to circulate, the country saw “exponential growth”, seeing its number of cases multiply more and more in three weeks. The country went into total blockade at the end of december.

At its peak in early January, Ireland saw 132 new cases per 100,000 people, according to Jha – a rate the United States has never seen.

Our vacation ‘peak’ was small in comparison, ”wrote Jha.

As it stands, Jha estimated that “maybe” 2% of COVID-19 infections in the US are caused by the UK variant.

“But we don’t know why we’re not doing enough genomic surveillance yet,” he wrote. “Therefore, most public health experts expect a peak in B117. But we can avoid a horrible spike that destroys our hospitals and kills tens of thousands. “

To prepare for and contain this increase in the variant, the United States needs to “substantially increase” genomic surveillance to research the strain.

Once infections start to increase, actions must be taken quickly to contain the spread, he said.

“Our vaccines will work against B.1.1.7,” wrote Jha. “And they will mitigate the effects on people at high risk if we can get them into combat quickly enough. Today’s analysis shows that B117 will spread across the United States, but it does not need to destroy us. We have the tools to beat it. “
