1. Under normal circumstance, a person that got infected with coronavirus such as MERS-CoV will automatically develop immunity immediately his body get rid of the acute disease causing virus. But as far a Covid-19 causing SERS-CoV2 is concern, there are a number of studies that disclosed that those who have been infected with the new virus are still at risk of re-infection after they recovered from the previous infection, that means they can still get sick from it.
2. Thus, I ask these TWO questions as follows:
a) Does that means our bodies are only developing a temporary/short-term immunity for the new virus or what exactly is going on?
b) Or is it that the virus is continuously mutating so that when a former covid-19 patient contract the virus for the second time, his body will not identify it as a similar virus to the previous one, so, the body has to produce different set of antibodies to fight it, making the already existing antibodies useless, since antibodies are always specific to antigens?
3. Anyway, such questions can only be answered by clinical researchers such as Dr Abdulaziz Tijjani, Dr Sadiq Saad and Dr Waziri Garba Dahiru. But I being a Geographical Epidemiologist, all I can say for now is:
a) Whether Covid-19 has come to go or to stay, mankind is going to survive it through what Charles Darwin called ‘The Survival of the Fittest’. As you you can vividly see that the unfit ones are already dying in tens of thousands by day, some knowingly, some knowingly.
b) Behold! The virus should be told that, it is not the only one that can mutate. Humans too ‘can’ also be mutants and adapt it.
4. It is important to recall that when almost 80% of native Americans died as a result of the arrivals of European colonialists and African slaves where the ‘leading cause’ of their deaths was known to be ‘Virgin Soil Epidemic’. That means, the guests came with new diseases such as smallpox, yellow fever, measles, flu and malaria among others to the native American hosts. And since the hosts’ systems have never had any experience of such diseases, then their bodies are immunologically highly vulnerable to the new diseases at first contact. Moreover, whenever there are more than one infections, the vulnerability increases. But yet those that are genotypically and phenotypically fit enough were able to survive, and there generations live to this day, in either their pure form as unmixed Amerindians, or in mixed forms such as mestizos, castizos, etc.
4. As for the current pandemic, thank God the Covid-19 causing SERS-CoV2 is already weak on young and healthy human systems at arrival.
