National health officials say some areas of the country will see a spike in new coronavirus infections over the next few months.

There are now more than 2 million confirmed cases in the U.S., according to Johns Hopkins University.

Experts say COVID-19 will pose a significant threat this summer. "Right now we have between 800 and 1,000 people dying every single day in America.  And all of the models, all of the data suggests that things are going to get worse. We're going to have increases," says Dr. Ashish Jha, of Harvard Global Health Institute.

The Harvard Global Health Institute predicts 100,000 more coronavirus-linked deaths in the U.S. by September. "The virus hasn't gone away, it's not like we're looking for the second wave.  The first wave isn't gone,"  Dr. Jonathan Reiner, professor at the George Washington University School of Medicine & Health Sciences.

Twelve states have seen coronavirus hospitalizations rise since Memorial Day, according to data from the COVID-19 tracking project
and there's been at least a 10% increase in week-to-week cases reported in 19 states, according to Johns Hopkins University. "Hospital leaders, they should be preparing for the next surge now, so that we don't run into the problem of not having enough masks and personal protective equipment.  I mean it was a national disgrace that we ran out last time," says Dr. Leana Wen, former Baltimore Health commissioner.

Johnson and Johnson is expected to start double-blind, randomized human vaccine trials next month. But in the meantime, health officials remind Americans to err on the side of caution. "I'm not trying to scare people to stay home, what I want is people to wear masks, I want them to do social distancing," says Dr. Jha.
