New story in Health from Time: CDC Head Estimates U.S. Coronavirus Cases Might be 10 Times Higher Than Data Show



In a press briefing on June 25, Dr. Robert Redfield, director of the U.S. Centers for Disease Control and Prevention (CDC), said that the current official count of COVID-19 cases in the U.S. may actually be a drastic underestimate.

Redfield said the new, much-higher estimate, is based on growing data from antibody testing, which picks up the presence of immune cells that react to SARS-CoV-2, the virus that causes COVID-19. People will test positive for antibodies to the virus if they have been infected—whether or not they ever got sick or even developed symptoms.

Previously, testing was focused only on those with symptoms. But because so many who become infected with SARS-CoV-2 could either have mild disease or not know they were infected at all, Redfield said, current information on the burden of cases is an underestimate. “The traditional approach of looking for symptomatic illness, and diagnoses obviously under estimated the total number of infections,” Redfield said. “Now that serology tests are available, which test for antibodies, the estimates we have right now show about 10 times more people have antibodies in the jurisdictions tested than had documented infections.”

That fact may also be contributing to the recent downward trend in the average age of people being diagnosed, since, as Redfield noted, those people were likely not being diagnosed in the past—younger people are less likely to experience the severe symptoms that bring them to the attention of the health care system, where the early cases were documented. Now that testing is more widely available in the community, it’s becoming clear that more people are currently infected or have recovered from COVID-19 than was previously believed.

On the press call, the CDC also announced changes to its definitions of people at high risk of COVID-19; it now includes those with asthma, dementia and a history of stroke, as well as people who are pregnant. The absolute risk of infection for these groups is still low, but compared to those without these conditions, the risk is worth noting. Based on new data, the CDC also updated its list of underlying medical conditions that could make people more vulnerable to COVID-19 to now include obesity and type 2 diabetes, conditions that are both common in the U.S. population, including among younger people.

New story in Health from Time: After Cruise Ships and Nursing Homes, Will Universities Be the Next COVID-19 Tinderboxes?

The fall semester has yet to begin, but student athletes training for the season can already be found on college campuses across the U.S. And so can COVID-19. Since the start of July there have been at least two outbreaks among student athletes, coaches, and staff—with 37 infected at the University of North Carolina (UNC) Chapel Hill and 22 at Boise State . Clusters of infection have been traced to college town bars popular with students. A common misconception is that young people with COVID-19 don’t die and therefore college re-openings pose little risk. Sadly, this isn’t the case. COVID-19 deaths in the young are rare, but they happen. Universities across the U.S. are mourning the loss of students in the lead-up to the school year, including Joshua Bush , a 30-year old nursing student at the University of South Carolina, Trevor Syphus Lee , a 27-year old senior at Utah Valley University, and Juan Garcia , a 21-year old Penn State undergraduate. One might imagine th...

New story in Health from Time: ‘We Are In Crisis.’ COVID-19 Exacerbates Problems for People With Disabilities

Jeiri Flores is normally a busy, upbeat 29-year-old. But amid the COVID-19 pandemic, her go-to thought has been dark. “If I get this,” she thinks, “I’m gonna die.” This is not an unfounded fear. Flores has cerebral palsy, uses a wheelchair and needs assistance with everyday tasks, including making food and getting dressed. Her disability means it’s tougher for her immune system to kick illnesses; she’s still recovering from a bout of pneumonia she had in January. So beating COVID-19 could easily mean a protracted battle and months in a hospital—a prospect that comes with a cascading series of challenges unique to people with disabilities. At a time when all Americans are facing unforeseen obstacles and concerned about their futures, Flores and more than 60 million Americans with disabilities like her are facing perhaps the toughest road of all. With hospitals restricting visitors amid the pandemic, Flores and others who rely on family and aides for assistance and advoca...
