US coronavirus: As 22 states report rising Covid-19 cases, CDC chief says more than 90% of Americans remain susceptible to virus

At least 22 states — mostly across the US heartland and Midwest — are reporting an increase in new Covid-19 cases compared to the previous week. Nationwide, the US is averaging more than 43,000 new cases per day — about double what the country was averaging back in June when lockdown restrictions were easing.

And the country is no longer seeing the kind of decline in deaths it was seeing in late August, according to infectious diseases expert Dr. Jeanne Marrazzo.

“The bottom line is that it doesn’t matter what side of the aisle you’re on politically,” Marrazzo said during an Infectious Diseases Society of America briefing Wednesday. “The numbers are the numbers. You can’t argue with them. And they are not going in the right direction.”

20% of summer Covid-19 cases were in young people

Warnings from experts have remained the same for months: wear a mask, wash your hands, social distance and avoid crowded places.

A new report from the CDC now shows people ages 20 to 29 accounted for more than 20% of all confirmed Covid-19 cases between June and August.

In June, Southern states saw an increase in positive tests among 20 to 39-year-olds a little more than eight days before increases among those 60 or older were reported — suggesting younger adults drove community spread of the virus.

The CDC noted younger people are more likely to work frontline jobs that leave them exposed and they may be less likely to heed social distancing guidelines. And because younger groups are more likely to have milder symptoms or show no symptoms at all, they could have been spreading the virus without ever knowing.

Covid-19 cases increase in children

More than 587,000 children in the US have tested positive for the virus since the start of the pandemic, according to the American Academy of Pediatrics and the Children’s Hospital Association.

The organizations found that 74,553 child cases were reported between September 3 and 17 — a 15% increase in this group over two weeks, according to their weekly pediatric report.

Cases listed by age are provided by health department websites in 49 states, New York City, the District of Columbia, Puerto Rico and Guam, but only a subset of states report hospitalizations and mortality by age, the groups said. The AAP called for more detailed reporting from states.

“At this time, it appears that severe illness due to Covid-19 is rare among children,” the report said. “However, states should continue to provide detailed reports on Covid-19 cases, testing, hospitalizations, and mortality by age and race/ethnicity so that the effects of Covid-19 on children’s health can be documented and monitored.”

More Phase 3 vaccine trials could begin

According to Dr. Anthony Fauci, the nation’s leading infectious disease expert, a “large proportion” of the US will not be vaccinated against Covid-19 this year.

“We’re not going to have all of the doses available, for example, by the end of December, they will be rolling in as the months go by,” Fauci said. “By the time you get to maybe the third or fourth month of the 2021, then you’ll have doses for everyone,” he said.

Those prioritized for the vaccine will likely be healthcare providers, people with underlying conditions and vulnerable populations, he said.
