Humans are likely to contract COVID-19 several times a year due to variations

A person can be reinfected with COVID-19 multiple times by being infected with different variants of SARS-CoV-2. This is a new warning issued by health authorities in many countries.

Director of the Scripps Research Institute in the US, professor of molecular medicine Eric Topol said that mutations of Omicron proliferate rapidly. All of these mutations have a disturbing feature in common: they can evade the immune system. With the rate of immune evasion increasing, experts warn it’s time to rethink our reliance on existing vaccines and work on next-generation vaccines. more effective against new variants.

Health officials also need to pay close attention to monitoring cases of people infected with the virus multiple times a year because of the potential for a host of other health problems, including post-COVID.

The SARS-CoV-2 virus continuously mutates through mutations, and sometimes these mutations lead to a New variant of the virus. If certain types of variation appear and disappear, others continue to rage. New variations will continue to appear.

Scientists track all variations, but can categorize certain types into the variant being tracked, the variant of concern, the variant of concern, or the variant with serious consequences.

Some variants spread more easily and faster than others, which could lead to more COVID-19 cases. Even if the variant causes less severe disease in general, an increase in the total number of cases could increase the number of hospital admissions, put additional strain on health care resources, and possibly lead to an increase in the number of deaths. death.

Omicron is one of the worrisome variants with many sub-strains B.1.1.529, BA.1, BA.1.1, BA.2, BA.3, BA.4 and BA.5. The data show that the Omicron variant is generally less severe. However, because it spreads more easily than other variants, a spike in cases can lead to increased hospitalizations and deaths.
