Coronavirus (COVID-19)

Coronaviruses are RNA enveloped viruses than can infect animals and humans. So far, there are six known human coronaviruses. Four of these coronaviruses are less pathogenic, generally causing only minor respiratory symptoms like the common cold. Two other coronaviruses—Severe Acute Respiratory Syndrome Coronavirus (SARS CoV) and Middle East Respiratory Syndrome Coronavirus (MERS CoV) —can cause serious respiratory diseases.
