People who get reinfected with COVID-19 have more health risks with each round of reinfection, a large national database study reveals.
People who get reinfected with the virus that causes COVID-19 have more health risks with each round of reinfection, a large national database study reveals.
"It is also possible that the first infection may have weakened some organ systems and made people more vulnerable to health risks when they get a second or a third infection," adds Al-Aly, a clinical epidemiologist at Washington University and chief of research and development at the VA St. Louis Health Care System."There are a lot of variables at play, but it is clear that reinfections contribute additional risks and they should be avoided.
"It makes sense, and let me explain why,” Mokdad says. “When you have somebody who got COVID-19 the first time and was impacted by it, maybe someone who was older or who had a chronic condition, the next hit would also cause more damage." He says a lot of people who get reinfected are testing positive at home. As a result, their cases don't make it into research. In contrast, the veterans in the study were"people who for whatever reason wanted to get a formal test."
