It’s not something people want to hear, but it’s something we all have to understand—it’s possible to become reinfected with COVID-19 after recovering from it. As frightening as that sounds, however, the news isn’t all doom and gloom.
COVID-19 hasn’t been around enough for researchers to know exactly how long immunity can last in a person. A few studies do indicate that immunity against COVID-19 can last for up to at least eight months. However, reinfection can occur even sooner than that, with some infections happening just a few months after an earlier infection. Yale University School of Medicine researchers published an article in the BMJ Case Reports informing people that early reinfections can—and do—occur. Let’s take a look at what the current research says about COVID-19 reinfections.
6. United Kingdom Study Regarding Reinfections
A study published on January 15, 2021, on 20,000 United Kingdom healthcare workers discovered that less than 1 percent of people who had COVID were infected again. Out of the 6,600 people with a previous COVID-19 illness, only 44 individuals came down with the disease again.
What’s more, people who were previously infected were also 83 percent less likely to be reinfected within five months after a COVID infection.
5. Research Performed in Marine Recruits
Also published in January 2021, in another study involving 3,000 Marine recruits, 10 percent of those who had a previous COVID infection had become reinfected with the illness. This information may sound disappointing, but just like the other United Kingdom study, those who had been infected before were over 80 percent less likely to have another COVID-19 infection compared to people who never had the illness.
