This pandemic-level virus that impacts the lungs is easily spread by small droplets through the nose and mouth and can survive on surfaces for a certain amount of time. COVID-19 is more contagious than the seasonal flu. While most of all COVID-19 cases to date are being reported as mild, some people become seriously and critically ill. People with lung health issues are among the most at risk, as they already have compromised lung health. Further damage to their lungs could be extremely detrimental.
