Covid 19:
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the coronavirus 2 that causes severe acute respiratory syndrome (SARS-CoV-2). In December of this year, the first known case was discovered in Wuhan, China. Since then, the disease has spread worldwide, resulting in a pandemic.
Fever, cough, headache, exhaustion, breathing difficulty, loss of smell, and loss of taste are some of the symptoms of COVID19. Symptoms might appear anywhere from one to fourteen days after being exposed to the virus. At least one-third of those who are afflicted do not show any signs or symptoms.
19 is spread by the air when droplets and small airborne particles containing the virus are inhaled. Breathing them in is most dangerous when individuals are close together, but they can also be inhaled over greater distances, especially indoors.
