What is COVID-19?

 

COVID-19, short for "coronavirus disease 2019," is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 

It was first identified in December 2019 in Wuhan, Hubei province, China, and has since become a global pandemic. COVID-19 primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks, and it can also spread by touching contaminated surfaces and then touching the face. 

Symptoms of COVID-19 can range from mild to severe and include fever, cough, shortness of breath, fatigue, body aches, loss of taste or smell, sore throat, congestion, nausea, and diarrhea. In severe cases, COVID-19 can lead to pneumonia, acute respiratory distress syndrome (ARDS), organ failure, and death. 

Prevention measures include wearing masks, practicing physical distancing, frequent handwashing, and vaccination.
