Researchers are reviewing hospital records of COVID-19 patients to understand whether certain medications—including flu vaccines, blood pressure medications (ACE inhibitors and ARBs), antihistamines, and —affected how patients recovered from COVID-19. The study will look at which patients were admitted to the hospital, how long they stayed, whether they needed intensive care, and their final outcome. If this medication appears to help patients recover better, doctors may recommend it more widely for COVID-19 treatment.
Early in the COVID-19 pandemic, doctors noticed that some patients seemed to recover better than others, and researchers wanted to understand why. By studying whether patients who were already taking certain medications or had received a flu vaccine did better or worse with COVID-19, doctors hope to identify treatments that could help future patients fight the disease.

You do not need to do anything active for this study. Researchers will simply review your existing hospital records from your admission to see what medications you were taking before you got sick, whether you received a flu vaccine, how long you stayed in the hospital, and what your outcome was. No visits, tests, or treatments are required on your part.
