Many people probably already know that. After being infected with the virus, symptoms will still appear as if you are sick. Even though we haven't detected the virus yet. Been cured for more than 28 days or a month or more. There are 3 main reasons:

1. Post viral syndrome is a symptom after infection with a virus. Which actually comes across every virus. have the flu or seriously ill and admitted to the hospital After we left the hospital The body will not recover well. Still feeling tired, fatigued, and not feeling refreshed. It's like we just fought, went through a war. Just like a soldier returning, he must recuperate. Sometimes wars drag on for a long time. When returning, soldiers may sometimes be tired both physically and mentally. It still makes me feel depressed. Or is it so severe that we call itPTSD (Post-Traumatic Stress Disorder) In fact, there are people talking about the same thing. PTSD after infection with the virus, found about 30% or 10 people, found 3 people with PTSD. That is, depression after we have recovered for more than a month or more. 

2. MIS (Multiorgan inflammatory syndrome) are various organs Still inflamed Even though the body had been healed for a month After measuring the inflammation in the bloodWe also found that the levels of inflammation in the blood were still high. Compare it to a fire that has not yet been completely extinguished. There is still fire in the body. There is still inflammation. Or try to think of a forest fire that spreads. Sometimes it can take weeks or sometimes even months for it to completely go off. If there are a lot of forest fires It must be up to our firefighting team to see if there are enough of them or not. If the more firefighting teams we have, for example, the less antioxidants we have. It may cause the fire to spread continuously. The inflammation will continue to spread. Causes inflammation in many organs.

3. Fibrosis is abnormal fibrous tissue. After the destruction of normal tissue Compared to the ruins of the war that had already been destroyed. All about the lungs fibrotic lung tissue muscle tissue nervous tissue All nervous systems that may not have returned, including the sense of taste and smell or numb hands and feet It may not have returned yet. 100% Especially since it's already been lost. Recovery takes time. Sometimes it may even last for several months. Until the new tissue is gradually restored. This is all the reasons that are the cause of Long Covid.

Many research studies include CDC (Centers for Disease Control and Prevention) also came out to say that “Symptoms after contracting the virus are not related to the severity of the disease.” It means that you are in the hospital or in home isolation. Whether you are seriously ill or mildly ill, you maySymptoms of illness after infection with the virus are approximately the same as 50%. This means that when you were sick you had few symptoms. But after recovering, it is still possible that there will be more symptoms.

There was a pair of patients who came to consult with a doctor. Be husband and wife When I was sick, my husband was more seriously ill and had to be hospitalized. have severe symptoms But my wife's condition is relatively mild, she has only minor symptoms and can be treated at home. But after recovering, it turned out that the husband was able to live a normal life. Symptoms after contracting the virus are very rare. But his wife still felt unwell. Plus, she looks more sick than when she was sick. Which has been cured for a month now but still hasn't healed. Even though trying to recover Trying to get back to running and exercising. But it turned out that “Running makes you tired.” More tired than usual.
