The new coronavirus (COVID-19) and the social impact on the elderly population in Brazil

Abstract

Coronavirus is a family of viruses that cause respiratory infections. The new coronavirus agent was discovered on 12/31/19 after cases registered in China. It causes the disease called coronavirus (COVID-19). The first human coronaviruses were isolated for the first time in 1937. However, it was in 1965 that the virus was described as coronavirus, due to the profile under microscopy, looking like a crown. Most people become infected with common coronaviruses throughout their lives, with young children being more likely to become infected with the most common type of virus. The most common coronaviruses that infect humans are alpha coronavirus 229E and NL63 and beta coronavirus OC43, HKU1.
