SARS-CoV-2, or severe acute respiratory syndrome coronavirus 2, is a single-stranded RNA virus that causes the disease known as COVID-19 in humans. Disease symptoms and modes of transmission are tightly linked to respiration processes. The virus is primarily spread via small, virus-laced particles called respiratory droplets that are released when an infected person coughs, sneezes, talks or exhales. Disease severity ranges from mild-to-severe, and common symptoms include fever, cough, shortness of breath, fatigue, sore throat, runny nose and body aches. Loss of taste or smell may also accompany infection.
