Coronaviruses are a large family of viruses. Some cause illness in people and others cause illness in animals. Human coronaviruses are common and are typically associated with mild illnesses, similar to the common cold.
COVID-19 is a new disease that has not been previously identified in humans. Rarely, animal coronaviruses can infect people, and more rarely, these can then spread from person to person through close contact.
The CDC recommends that patients with the coronavirus wear a face mask to protect others around them, or, if the patient cannot wear a face mask, others should, if they are in the same room together. Masks alone will not prevent the spread of COVID-19.
You must consistently and strictly adhere to good hygiene and public health measures, including frequent hand washing and physical (social) distancing.
