Omicron Subvariant – BA.2.75

We all know that the RNA virus of COVID-19 (SARS-CoV-2) is constantly mutating, and new variants are emerging with time. After the first emergence, coronavirus has undergone numerous mutations. Most mutations are insignificant, but a few strains are variants of concerns, such as alpha, beta, delta, and omicron.

What is omicron and its subvariants?

The omicron variant of the coronavirus emerged at the end of 2021, and from then, it’s continuously mutating. The symptoms of the omicron variant are different from the classic coronavirus infection. Instead of classic symptoms like cough, cold, fever, and loss of taste and smell, the omicron symptoms are more like the common cold, such as runny nose, sneezing, and sore throat. According to some research, the omicron symptoms are milder in vaccinated than in non-vaccinated people.

Since omicron emergence, numerous mutant strains come into existence. The omicron virus is more potent in mutation than other variants of the coronavirus. The virus is still evolving, and we can see the rise in COVID cases. Now, most of the COVID-19 cases are due to omicron subvariants, and all the subvariants come in variant of concern category. In India, the new sub-lineage omicron BA.2.75 has emerged, which has also been classified, as a variant of concern.

What is subvariant BA.2.75?

BA.2.75 is the latest emergent sub-lineage of the omicron variant. As it is a recent evolution, extensive information is not available. But according to the latest statistics, the symptoms of this subvariant are more like cold symptoms, and the virus is highly transmissible.

With the continuously mutating and emerging new variants every time, they are becoming more contagious, and the chances of high or low seriousness vary, as we can’t predict the definite consequences. According to the latest statistics, the newly developed sub-lineage omicron BA.2.75 has become the prominent variant globally. Numerous virologists have analyzed this latest subvariant and stated that although it’s early to conclude anything about the course of action, still omicron BA.2.75 is more transmissible than other variants and has the power to detour the immunity developed from prior infections or vaccination”.

What are the symptoms of omicron BA.2.75?

According to the latest statistics on patients’ experience after omicron BA.2.75 infection, the ailments are mild with no distinct symptoms in most cases. With time, the number of severe COVID-19 patients decreases. The symptoms of omicron BA.2.75 are mostly flu-like and may last more than 4-5 days. The following are the symptoms of this subvariant:

  • The most common symptom is a sore throat that causes dryness, itching, and pain in the throat
  • Low-grade fever
  • Runny nose
  • Sneezing
  • Mild to moderate fatigue
  • Headache

Although the symptoms of the omicron BA.2.75 virus are mild, this subvariant is spreading rapidly and invading prior immunity, thus making it more alarming to the elders and persons with lower immunity.

What is the severity of the omicron BA.2.75 subvariant?

Virologists and experts till now can’t conclude whether the omicron BA.2.75 subvariant is a more severe infection than its predecessor’s corona variants. The chances of reinfection are much higher in omicron than in other variants.

Where has the omicron BA.2.75 subvariant been first detected?

According to the latest reports, the most recent sub-lineage of omicron, BA.2.75 strain, has been spotted in several states in India and spreading faster than other variants. Along with India, this subvariant is now also detected in numerous countries, including Canada, the United Kingdom, Germany, and Australia. Now, this sub-lineage has become a global matter of concern.

As we know, the coronavirus is continuously mutating, and every time a new variant or subvariant emerges and becomes more contagious.

Are vaccines effective against omicron BA.2.75 subvariant?

With the continuous evolution and transmission of the coronavirus, it becomes more dangerous. Even though this subvariant causes mild ailments, the infection rate is higher. According to numerous researchers and healthcare professionals, vaccines and booster doses don’t prevent getting an infection, but they reduce the risk of severity and morbidity. Vaccination and corona infections cause a gradual increase in herd immunity worldwide.

Healthcare professionals suggest that vaccines (both the primary and booster dose) are the best defense against hazardous coronavirus infections.

As we don’t have sufficient statistics against this latest subvariant, the healthcare providers suggest booster jabs, wearing the appropriate mask, sanitization, and social distancing. If you get the virus, isolate and quarantine yourself. We all want to return to our pre-pandemic routine, but with these continued mutations, we need to accept that living with these conditions with much alertness is the new normal.
