CDC study finds nursing home residents who appear to have recovered from Covid were reinfected with an even worse case

In fact one of the reinfected persons died.

A new CDC study published Thursday suggests some people may be susceptible to reinfection from the coronavirus and could have worse outcomes following their second infection.

Reinfection means that a person was infected with the virus, recovered and then later became infected again, though it’s thought to be rare, according to the CDC.

The new study found five nursing home residents tested positive during two separate outbreaks with multiple negative tests in between, suggesting they were reinfected with the virus.

My question would be if they were reinfected with a variant.

Study Shows Young COVID Survivors Can Get Reinfected

The finding stems from tracking nearly 3,250 young U.S. Marine recruits between May and October. Of those, 189 had previously tested positive for the SAR-CoV-2 virus. During the six-week study itself, 10% of those who had tested positive got reinfected.

"You don't have a get-out-of-jail-free card just because you have antibodies from a previous infection," said study author Dr. Stuart Sealfon.

He's a professor of neurology at Icahn School of Medicine atMount Sinai in New York City, which conducted the study in collaboration with the Naval Medical Research Center.

The findings were recently published in the preprint server medRXiv and have not been peer-reviewed.

All the Marines were beginning basic training and were initially held in Navy quarantine for two weeks, after two weeks of at-home quarantine, according to the study. Once training began, recruits were tested for COVID-19 every two weeks over a six-week period.

The result: 19 of the 189 recruits who already had COVID tested positive for a second infection during the study.

Researchers said first- and second- infections involved the same strain of the SARS-CoV-2 virus and none involved the new, more transmissible U.K., South African or Brazilian strains that have raised alarm in recent weeks.
