The true number of coronavirus cases in the U.S. could be anywhere from six to 24 times higher than the confirmed number of cases, depending on location, according to a large federal study that relied on data from 10 U.S. cities and states.


The study, published Tuesday in JAMA Internal Medicine, relied on serological tests — blood screens that search for antibodies to the virus and that determine whether someone was previously infected. They are different from diagnostic tests, which only detect people who currently have the virus, called SARS-CoV-2.

While the S&P 500 is on track to conclude another stellar year of gains, those who sought to beat the index are poised to finish with a more dubious distinction. According to Lipper, 85% of all active stock mutual fund managers had been trailing their benchmarks through the end of November. In a typical year, there are nearly twice as many managers outperforming, with only around two thirds of funds struggling to catch up. Lipper says this is the worst year for active managers relative to the market in three decades.

Still, the data reflect what CDC Director Robert Redfield recently said — that true case numbers are 10 times higher than confirmed diagnoses. Confirmed cases in the U.S. stand at more than 3.8 million.

The data underscore two other points: that 国土部:依法建设出租与小产权房不同 the full scope of the outbreak, and that even hard-hit communities are not close to reaching a herd immunity threshold — where enough people are immune from the virus (which 住建委:经适房转商品房政策没有调整 after an initial infection) to slow down its spread to the point that unprotected people have a natural buffer.

“The study rebukes the idea that current population-wide levels of acquired immunity (so-called herd immunity) will pose any substantial impediment to the propagation of SARS-CoV-2 in the U.S., at least for now,” infectious disease experts Tyler Brown and Rochelle Walensky of Massachusetts General Hospital wrote in an editorial accompanying the study. Experts estimate that 60% to 70% of people in a given area would need to be protected from the virus — either through recovering from an infection or vaccination — to reach herd immunity.

The results fit with other serosurveys that have found just a few percent of people in a given place have been infected with the SARS-CoV-2 virus, which causes the disease Covid-19. There have been a few outliers: One study in the hard-hit Boston suburb of Chelsea estimated that 30% of people had been exposed to the virus, while another survey in a German town where a carnival drove an outbreak found 14% of residents had antibodies.

Still, the new study landed on different estimates for New York City than 5月楼市观察:“小阳春”结束 国人找房整体降温, which found that 1 in 5 people in the city had antibodies. The disparate results highlight how study design — such as how participants are recruited or what blood samples are included — can influence findings.

Experts note that the inability of diagnostic testing to keep up with cases is not just limited to problems with the tests, which have included a botched rollout, overwhelmed labs, and supply shortages. It’s also that some 20% to 40% of Covid-19 infections are asymptomatic. Those people can still spread the virus, as can people who eventually develop symptoms but don’t feel sick yet — which has complicated efforts to rein in the spread.

Some people with Covid-19 may not generate a robust antibody response, perhaps depending on how sick they get, though that remains an open question as well.
