Second COVID-19 infections are rare and likely mild, research finds


People who catch COVID-19 twice will likely have a milder bout with the disease the second time around, an analysis of U.K. government figures found.
The research, conducted by the U.K.'s Office for National Statistics, indicates that viral loads are higher for people who are dealing with their first infection than those who have been reinfected. The more virus that's present in the body tends to lead to a more intense case of COVID-19.
The study also found that the rate of reinfection was low overall, and the rate of reinfection with a "strong positive test," which suggests a higher viral load, was even lower. All told, the numbers hint that previous exposure to the coronavirus helps protect people from future run-ins. Read more at Bloomberg and check out the full research U.K. analysis here.
