Respiratory illnesses like the flu, RSV and COVID have climbed after the holidays — though COVID levels are still far below what they were at the height of the pandemic. Many wonder how they've avoided COVID infections while in close contact with roommates and family members. Here's the science behind the spread:
➡️ By now, most immune systems can recognize the virus and initiate an immune response, meaning symptoms may show before you are contagious.
➡️ The infectious window and the amount of virus shedding vary from person to person.
➡️ For a pathogen to cause disease, you must be exposed to enough of it to overcome your immune system. Masks, open windows and HEPA filters can reduce the amount of virus in the air.
