It can be mild, as seen in most of the cases. But the possibility of a severe infection can not be ruled out.

Since the emergence of the Omicron variant, cases of COVID reinfection have sprung up. The main reason behind this surge in reinfection cases, experts say, is lack of immune power against the new variant.

Omicron is notorious for its super transmissibility and its immune evading power. Due to the several mutations this variant of coronavirus has, the immune system is unable to recognise it.

Hospitalization cases were less during the Omicron-led COVID wave. While many assume it to be the mild nature of the variant, health experts say it might be because of the vaccination. The body has partial memory of the attacker and hence could protect it from the severity of the viral attack.

This draws attention towards how severe the COVID reinfection can be. With an immune system that has lost its memory since the last infection or vaccination, the body is almost entirely susceptible to the viral attack as it was during the first time.
