So far, no satisfactory answer has been found as to whether a person once infected with corona can get it again. Some scientists say that once an infection occurs, the human body develops immunity against it. But there have been some cases in China in which people got re-infection a few weeks after their discharge from the hospital. According to a study in China, so far only a particular species of monkey has been successful in developing immunity against it.

If the human body develops resistance then the question is how many days this capacity will remain intact. Till now it has been seen that immunity against such viruses does not last long.  People who have a lot of antibodies can also get infected. In the case of SARS, it was revealed that the body of a man once cured has immunity even for 15 years. At the same time, in the case of Mars, resistance was seen to decrease very fast. So now the whole thing is that even if the human body develops resistance to corona, it will be long term or short term.

However, there has come an exception to it. Initially, there were cases in many countries where the corona report of the patient came back positive even after treatment. There have been many types of research about this, the researchers claim that the patient report came positive after weeks of recovery. There is no danger.

Research by scientists from the Center of Disease Control and Prevention of South Korea has revealed that reports of corona patients recovering after treatment are positive. The reason for this can be the dead particles of corona virus present in their body. But there will be no risk of infection from this.
