The new study found ‘significant’ cases of COVID-19 that were not reported, OHA said



PORTLAND, Ore. The Oregon Health Authority released a coronavirus study on Friday indicating that a “significant” portion of Oregonians had an undiagnosed and unreported case of COVID-19.

Research, conducted by OHA epidemiologists, found that 1% of Oregonians without COVID-19 had evidence of a virus infection in their blood.

The number is 10 times higher than the reported infection rate detected through conventional testing, officials say.

“We suspect that a large portion of the Oregon population has been exposed to and infected with COVID-19,” said Paul Cieslak, MD, study co-author and OHA medical director for infectious diseases and immunizations. Traditional diagnostic tests. “But these results also tell us that the majority of Oregonians are still sensitive to the virus.”

Nine out of 897 blood samples collected from 19 health care facilities across Oregon between May 11 and June 15 contain antibodies against the virus that causes COVID-19.

The incidence of infection has been shown to increase with age, with no antibodies found in the blood of children 17 years of age and younger.

The first case of coronavirus infection in Oregon was diagnosed on Feb. 28. As of May 31, 4,243 people had tested positive, but this data did not include those who did not seek the test.

“Because most of us are still sensitive, we need to keep practicing long distances and cover our faces until we have effective vaccines, treatments or disease relief methods,” Cieslak said. . “

Cieslak says antibodies don’t appear in your bloodstream until two to three weeks after coming into contact with the virus. At this point, he added, experts are unsure if antibodies will guarantee protection against COVID-19.
