These days, it’s tempting to compare COVID-19 with the common cold or flu. It can similarly leave you with a nasty cough, fever, sore throat—the full works of respiratory symptoms. And it’s also become a part of the societal fabric, perhaps something you’ve resigned yourself to catching at least a few times in your life (even if you haven’t already). But let’s not forget: SARS-CoV-2 (the virus responsible for COVID) is still relatively new, and researchers are actively investigating the toll of reinfection on the body. While there are still a lot of unknowns, one thing seems to be increasingly true: Getting COVID again and again is a good deal riskier than repeat hits of its seasonal counterparts.
