TUESDAY, June 30, 2020 (HealthDay News) -- Top U.S. infectious disease expert Dr. Anthony Fauci warned Congress on Tuesday that COVID-19 infections could climb to 100,000 new cases daily unless ongoing outbreaks are contained. "For people who are younger, people who don't look like me, they probably need to be hearing this, not just from government officials but from people who are in their circles, their influencers, people who they respect. The federal government has included community engagement programs at the sites of vaccine clinical trials to help build trust in vaccination among participants, Fauci said.
