COVID-19 Cases Detected in US Earlier Than Previously Reported
In the United States, COVID-19 cases were detected earlier than previously reported, revealed a new study by the US National Institutes of Health (NIH).
NIH researchers analysed more than 24,000 stored blood samples from all 50 US states between January 2 and March 18, 2020, Xinhua news agency quoted the study as saying.

They detected antibodies against SARS-CoV-2, the virus that caused Covid-19, using two different serology tests in nine participants' samples.

Seven of those samples were seropositive prior to the first confirmed case in the states of Illinois, Massachusetts, Wisconsin, Pennsylvania, and Mississippi, according to the study published by the Clinical Infectious Diseases journal.

The study is the latest to suggest the coronavirus first appeared in the US earlier than previously known.
