Herd immunity played no role in decreasing COVID-19 cases: NYC’s top doctor
Herd immunity wasn’t a factor in decreasing the number of cases of coronavirus in New York City, a top city doctor said Friday.
COVID-19 cases in the city have consistently been on a downward trend during the reopening process — despite dozens of states across the country reporting upticks.
But Mayor Bill de Blasio and Dr. Jay Varma attributed the city’s good numbers to everything but herd immunity — including social distancing, good hygiene and an increase in testing and tracing.
“I think that herd immunity is a very unlikely explanation for this because we know the vast major of New Yorkers actually weren’t infected, so we’re not nearly at a level where we would expect that immunity would play a major role in decreasing transmission,” Varma, the city’s senior adviser for public health, said at the mayor’s daily press briefing.
“There’s still far too many New Yorkers that are susceptible,” he added.
De Blasio noted that the city is up to 40,000 coronavirus tests a day.
He also credited New Yorkers’ vigilance in fighting the spread of the deadly disease.
