Coronavirus is a virus that typically affects the airways of birds and mammals, including humans. Doctors have linked them to the common cold, bronchitis, pneumonia, severe acute respiratory syndrome (SARS) and covid-19. They also affect the gut.
These viruses are more likely to cause the common cold than serious illness. However, coronavirus has also caused some more serious outbreaks.
Over the past 70 years, scientists have discovered that coronavirus can infect mice, rats, dogs, cats, turkeys, horses, pigs and cattle. Sometimes, these animals transmit coronavirus to humans.
In the 1960s, scientists found the first evidence of human coronavirus (HCoV) in the noses of people with the common cold. Two human coronaviruses are responsible for most common colds: OC43 and 229E.coronavirus Judge Memorial Catholic High School
