With over 2 million cases in the US since the coronavirus pandemic began in late December, there are now many people who have recovered from COVID-19. At the same, there have been reports of people who continue to have long-term side effects from the infection.   I am a professor and physician and I specialize in infectious diseases of adults. I not only care for patients with bacterial, parasitic and viral infections - including COVID-19 – but actively teach and perform research into diseases that infectious pathogens cause.
