Hong Kong’s scientist has announced the first confirmed case of reinfection by the coronavirus and is backed up by genetic sequences of the 33-year-old man who was infected in March and in August 2020. But there is no much of the evidence about the reinfection of COVID19 after nearly nine months following the first infection.
People in India and China are also about the new cases of coronavirus re-infection.
The reinfection of coronavirus is common says the virologists and immunologists are trying their best to determine about the signs of protective immunity that will last in healed patients. There is no need for any alarm.
The new increase of the virus is very short-lived and the infection is defeated before the infected person experiences the symptoms or even notices.
The Hong Kong patient did not show any signs of the reinfection, which was found after regular testing at the airport.
The people who are reinfected without any symptoms are contagious equally to the ones who are showing symptoms. Hence, wearing face masks would avoid infecting other people and also avoid getting infected.

Hence, wearing face masks would avoid infecting other people and also avoid getting infected. The virus from previous colds have given some with memory T cells that can also prepare against the coronavirus and this could reveal about the people who spared severe disease.
There is no sign for disease enhancement in coronavirus with over 23 million confirmed cases of COVID-19 globally.
Some of the patients who are reinfected twice may not have adequate immunological memory left to defend from infection. This could result because of the first infection that did not need antibodies or T cells to be resolved, possibly because other deployed immune defences were sufficient to constrain.
The antibody and T cell responses different in COVID-19 patients that anticipate immune protection if efficient and may vary in different people.
The strength and duration of the immunity are when it strikes a large number of healed patients immune to reinfection. It will protect the most exposed. Hence vaccination is important to produce and maintain the immune system.
Vaccination can get more effective and immune responses in the long run compared with natural infection, and these can be nurtured by booster vaccinations when needed. Hence, the scientists were not shocked to learn about reinfection.
