Coronavirus disease 2019 or (COVID-19) is an infectious disease caused by the coronavirus SARS-CoV-2.^[5] This virus is kind of like the older SARS virus.^[6][7][8]

The virus, SARS-CoV-2, is the cause of the COVID-19 pandemic.^[9][10] People who get the infectious disease, COVID-19, may get a fever or a dry cough. They might get fatigued, which is being very tired. People might lose their taste, smell, and a way to breathe. They might get sore throat or runny nose, and they might sneeze.^{[11][12][13][9]} COVID-19 can kill people. COVID-19 has killed more than six million people around the world.^[14] Some infected people are asymptomatic, which means that they can make others sick, without looking sick.

5 to 50 percent of people who get the disease, COVID-19, will get Long COVID.^[15]

The COVID-19 virus, SARS-CoV-2, goes from one person to another by droplets. It can also go from one person to another by small airborne particles. Droplets and particles are made when a person breathes, sneezes, or talks.^{[16][17][18][19]}
