Coronavirus

Coronaviruses are a family of RNA viruses affecting mammals and birds. In humans, they primarily cause respiratory infections, ranging from mild colds to severe diseases like SARS, MERS, and COVID-19. Other animals experience different symptoms; cows and pigs get diarrhea, while mice can develop hepatitis and encephalomyelitis. The severity and specific symptoms vary significantly depending on the virus strain and the host species.
