For many years, doctors have been concerned about overuse of antibiotics to fight infections caused by bacteria. COVID-19 is a virus and does not respond to antibiotics. Recently, people who are hospitalized because of COVID-19 have been given antibiotics to prevent a second infection from other bacteria. This is worrying because it could lead to a situation where bacteria become resistant. This occurs when the antibiotic does not work anymore, and could leave us vulnerable to even more infections.
