SARS-CoV-2 is the seventh coronavirus to cause human-to-human infection, and as of May 2021, variants that have acquired mutations associated with increased transmissibility and immune evasion are a worldwide problem. About 30-40% of infected people are considered asymptomatic, but the incubation period of those who develop the disease is about 5 days, and they develop flu-like symptoms. Olfactory and gustatory disturbances are highly specific to COVID-19. The typical course of the disease is that about 20% of patients become severely ill 7 to 10 days after onset. Elderly people, patients with underlying diseases, and obese patients are at increased risk. The so-called sequelae of LONG COVID, in which symptoms persist even after the patient has recovered from the acute phase has become an important topic.
