Specialised immune cells in the body are tasked with remembering each particular infection, so if you get infected again your body quickly starts producing the relevant antibodies
Current Affairs:A Hong Kong man who recouped from COVID-19 over four months back has apparently been reinfected with SARS-CoV-2, the infection that causes COVID-19. This time he didn’t have any manifestations.
This isn’t really unforeseen, in light of the fact that not many regular contaminations create a resistant reaction that totally forestalls reinfection. Rather, what by and large occurs after a disease is that the body’s safe reaction bit by bit decays over months after the contamination is cleared.
Specific insusceptible cells in the body are entrusted with recalling every specific disease, so on the off chance that you get contaminated again your body rapidly begins creating the important antibodies and other invulnerable cells (called T cells) in huge numbers. This helps clear the new disease all the more quickly and viably. So you can in any case get reinfected, yet you’re bound to have less manifestations or be asymptomatic.
This is the thing that appears to have happened to the 33-year-old Hong Kong man at the focal point of the most recent reports. The primary disease caused indications, which he purportedly experienced for quite a while. Be that as it may, the second time around he was asymptomatic, apparently on the grounds that his body successfully repulsed the illness.
