RESUMO
A virus is an infectious agent that can only replicate within a host organism and can infect a variety of living organisms, including bacteria, plants, and animals. Viruses are so small that a microscope is necessary to visualize them, and they have a very simple structure. A coronavirus is a group of viruses that can cause diseases, for instance, the basic cold, severe acute respiratory syndrome (SARS), and the Middle East respiratory syndrome (MERS). The patients affected with the COVID-19 infection will encounter respiratory sickness and can recuperate without requiring normal therapy. Individuals with clinical issues like cardiovascular problems, diabetes, and respiratory illness will suffer from the ailment. COVID-19 disease spreads through aerosols or the nose when an infected individual hacks or sneezes. In 2019, a new disease, known as novel coronavirus disease 2019 (COVID-19), was discovered in China, and on March 11, 2020, it was declared a pandemic disease by the World Health Organization (WHO), spreading rapidly across 194 countries in Europe, North America, Asia, the Middle East, Latin America, and Africa. The best way to stop the spread of the transmission is to be instructed about COVID-19 and how it spreads. In this survey, we are endeavoring to focus on the drugs and vaccines that are used for the treatment and prevention of COVID-19.
