The expanded COVID-19 survey dataset now consists of responses from practically 100,000 contributors, which might enable researchers to glean new insights from the wide-ranging info.

“It is a actually numerous group,” All of Us Chief Govt Officer Josh Denny instructed Healthcare IT Information. “They’re very engaged, and we’re enthusiastic about the place issues are.”
