“Recent evidence suggests that children likely have the same or higher viral loads in their nasopharynx compared with adults and that children can spread the virus effectively in households and camp settings,” the guidance states.
Transmission of the virus to and among children may have been reduced in spring and early summer due to mitigation measures like stay-at-home orders and school closures, the CDC says.
“So if I'm put into a classroom of 30 or more kids, it's a small room, there's one exit, the ventilation isn't all that great for schools,” Arizona teacher Matt Chicci, who quit his job, told CNN. “It's not a good situation.”
In Georgia, where several districts reopened in recent weeks, more than 1,000 students and staff were asked to quarantine following cases of coronavirus or exposures to someone infected. While some US officials — including the President — have downplayed the risk coronavirus positions on children, the new CDC guidance notes children can develop severe illness and complications, even if that risk is lower compared to adults. The rate of hospitalizations among children is increasing, the guidance says, and among those hospitalized, one in three children is admitted to intensive care — the same as adults. In the US, more than 5.3 million people have been infected with the virus and at least 168,446 have died, according to Johns Hopkins University.
Black and Latino populations hit hard in hotspots
Research published Friday from the CDC also showed that in hotspot counties across the US, Black and Latino people were hit hard by the virus, with a majority of the counties reporting disparities on coronavirus cases in one or more racial or ethnic groups.
“These findings illustrate the disproportionate incidence of Covid-19 among communities of color, as has been shown by other studies, and suggest that a high percentage of cases in hotspot counties are among person of color,” said the authors.
In Milwaukee, Wisconsin, health officials say collecting coronavirus impact data by race helped them better strategize a response to the pandemic.
“[It] helped us alter our strategy so we could increase our outreach, add additional testing sites, just really help our communities of color prevent their exposure to Covid-19,” said Jeanette Kowalik, commissioner of health at the Milwaukee Health Department.
Kowalik said the data drove conversations that wouldn't have taken place if officials weren't aware more people of color were impacted by the virus.
Doctors warn of lasting heart complications
With new evidence and data on the virus emerging almost weekly, health officials now have another warning: the risk of death from coronavirus-related heart damage seems to be far greater than previously thought, the American Heart Association said.
Inflammation of the vascular system and injury to the heart occur in 20% to 30% of hospitalized coronavirus patients and contribute to 40% of deaths, the association said Friday.
Dr. Mitchell Elkind, the association's president, said that the cardiac complications of Covid-19 could be “devastating” and linger after recovery.
The AHA said research indicates coronavirus could lead to heart attacks, acute coronary syndromes, stroke, blood pressure abnormalities, clotting issues, heart muscle inflammation and fatal heartbeat irregularities.
It's a statement that's long been hinted by coronavirus patients across the country, whose bodies were attacked in different ways by the coronavirus.
In Florida, a 21-year-old suffered heart failure while in the hospital and weeks since his recovery, his heart rate is still monitored and he's on medication for his blood pressure — medications his doctors have said could continue for at least another year.
There is a critical need for more research, Elkind said.
“We simply don't have enough information to provide the definitive answers people want and need.”
