A small number of newly crowned infected persons may have sequelae manifestations such as decreased lung function, loss of taste, loss of smell, and decreased sexual ability, etc. The details need to be further observed. New crown infection patients may lead to irreversible damage of lung tissue such as pulmonary fibrosis after healing, and after healing, they may have sequelae manifestations of decreased lung function such as breathlessness and frequent wheezing after exercise. Some neocollared infected patients may suffer from loss of taste, smell, or even taste and smell after the disease is cured. There are some reports of decreased sexual function in men as a result of neo-crown virus infection. However, on the whole, the probability of residual sequelae after neocollins infection is small, and the long-term sequelae need to be kept under observation.
