Background

BA.2.75 is a subvariant of the Omicron variant of the SARS-CoV-2 virus, the virus that causes COVID-19.
It was first identified in India in May 2022 and has since been detected in several other countries, including the United States, United Kingdom, and Canada.

Characteristics

BA.2.75 has several mutations that distinguish it from other Omicron subvariants, including:
- L452R: This mutation is associated with increased transmissibility.
- E484K: This mutation may help the virus evade the immune system.
- Q493R: This mutation may also contribute to increased transmissibility.
Studies suggest that BA.2.75 is more transmissible than previous Omicron subvariants, such as BA.1 and BA.2.
However, there is currently no evidence that BA.2.75 causes more severe disease than other Omicron subvariants.

Transmission

BA.2.75 is transmitted through close contact with an infected person, similar to other COVID-19 variants.
The virus spreads through respiratory droplets produced when an infected person coughs, sneezes, talks, or sings.
It can also be spread through contact with contaminated surfaces or objects.

Symptoms

The symptoms of BA.2.75 are similar to those of other COVID-19 variants and may include:
- Fever or chills
- Cough
- Shortness of breath or difficulty breathing
- Fatigue
- Muscle or body aches
- Headache
- New loss of taste or smell
- Sore throat
- Congestion or runny nose
- Nausea or vomiting
- Diarrhea

Treatment

There are currently no specific treatments for BA.2.75.
Treatment for COVID-19 in general includes supportive care, such as rest, fluids, and over-the-counter medications to relieve symptoms.
Antiviral medications, such as Paxlovid and Molnupiravir, may be prescribed to high-risk individuals.

Prevention

The best way to prevent BA.2.75 and other COVID-19 variants is through vaccination.
Vaccines are highly effective in reducing the risk of severe disease, hospitalization, and death from COVID-19.
Other preventive measures include:
- Wearing a mask in indoor public settings
- Maintaining physical distancing
- Washing your hands frequently
- Staying home if you are sick
Getting tested for COVID-19 if you have symptoms or have been exposed to an infected person

Global Impact

BA.2.75 has become the dominant variant in several countries, including India, South Africa, and the United Kingdom.
Its increased transmissibility has led to a rise in COVID-19 cases in these regions.
However, there is no evidence that BA.2.75 is causing more severe disease or hospitalizations compared to other Omicron subvariants.

Conclusion

BA.2.75 is a more transmissible subvariant of the SARS-CoV-2 virus. While it is important to be aware of this variant, there is currently no evidence that it causes more severe disease than other Omicron subvariants. Vaccination remains the best way to protect yourself from COVID-19, including BA.2.75. Continue to follow preventive measures, such as masking and social distancing, to reduce your risk of infection.
