In addition, the research group investigated whether there was a relationship between receiving treatment with antiviral drugs and steroids when symptoms appeared after being infected with the new coronavirus and the persistence of symptoms, but there was a clear relationship. It means that it was not possible.

likely to have
taste abnormalities,

In addition, young and thin people are more likely to have abnormal taste and smell, and even if the symptoms of the new corona are mild, there are cases where the symptoms that are considered to be sequelae are prolonged.
Doctor "Vaccine may prevent sequelae. Inoculation of young people is important."
Dr. Shinichiro Morioka of the National Center for Global Health and Medicine, who conducted the survey, said, "It has been said that women are more likely to have sequelae than men, but this time we will discuss hair loss, taste / smell disorders, and malaise according to symptoms. It has become clear that women are more likely to develop corona. Men are at higher risk of corona aggravation in the acute phase, and elderly people tend to be obese. It's not clear. "
On top of that, "Even young, lean women should not underestimate the aftereffects. Rather, it is very important to accept the fact that taste and smell disorders are likely to occur. Also, taste and smell disorders are caused by young people. Sequelae are a major problem for both mild and young people with corona symptoms. Recently, those who have been vaccinated twice have 28 days compared to those who have not. As mentioned above, there are reports that the symptoms are difficult to continue. It is becoming clear that the vaccine may prevent sequelae, so it is very important for young people to take the vaccine twice just in case. However, even if you inoculate the vaccine, there is a risk of sequelae if you are infected with corona, so it is important to continue basic infection control measures. "
