Question

writes a composition about Coronavirus Pandemic.​

Answer 1

Respuesta: Coronaviruses are large enveloped RNA viruses. Human coronaviruses cause the common cold, can cause infections of the lower respiratory system, and have been said to be involved in gastroenteritis in infants. A new coronavirus was identified as the cause of a worldwide outbreak of severe acute respiratory syndrome (SARS) in 2003. Coronaviruses cause diseases of economic importance in pets; in wild animals they establish persistent infections in their natural hosts. Human viruses are difficult to cultivate and therefore have a poorer characterization.
