You may be thinking that getting infected by (SARS-CoV2) and surviving it would give you protection from further infection. But is this assumption really true? Will you indeed be immune to the SARS-CoV2 after you’ve recovered from a COVID-19 infection? Some reports out of Japan and China seem to suggest otherwise.
Recently, a female tour bus guide in Japan was tested positive for the virus after recovering from a COVID-19 infection.
Does this case actually prove that re-infection with the virus is possible? Or was this just a mistake in the testing? Or did the person have a particularly weak immune system so that she couldn’t generate immunity?
According to a more recent NHK-World Japan report, a man in his 70’s, who first tested positive for SARS-CoV2 on February 14 while on a Diamond Princess cruise ship, has tested positive for the virus again.

Remember, no test is perfect. If people can screw up a drink order, they can certainly mess up a medical test. Even if a test is performed properly, you could still get a positive result when you don’t actually have an infection. On the flip side, just because you test negative doesn’t necessarily mean that there is no way that you are carrying the virus. That’s why a doctor may test you multiple times to be sure of a result.
It all depends on Your Immunity System
the amount of immunity that you build up after being exposed to any virus depends on not only virus itself but surprise, surprise your immune system and its response. When your immune system sees a particular virus for the first time, it can essentially get caught with its pants down, not ready to defend your body against this new invader. However, exposure to the virus either through a vaccine or getting infected may train your immune system.
