Although the cases of corona have come down, it is completely wrong to assume that the danger of corona is completely averted. Recently another sub-variant of Omicron has been found in our country. It has been named XBB. This variant has been found in Odisha, Karnataka, Gujarat and Rajasthan. Earlier this variant has also been found in Europe and America. For information, let us tell you that in India, more than 50 cases of new sub-variants have been registered so far. According to a report published in TV9, Dr. Jugal Kishore says that there is a constant mutation in the corona virus and due to this new sub-variants are coming. Dr Kishor says that in the history of the last nearly three years of Corona, it has been seen that after any major festival in India, the cases of virus start increasing. Since people meet during festivals and do not even follow the rules of prevention from Kovid during this, due to which the virus gets a chance to spread. In such a situation it is very important that people wear masks.

Now a new sub-variant of the new variant of the coronavirus, Omicron, has also been revealed. This new sub-variant of Omicron has been named Stealth Omicron (BA.2). After Denmark, UK, Sweden and Singapore, this variant has also come to India. The symptoms of the Omicron variant are less severe than the Delta variant, but the Omicron's sub-variant stealth has been voicing concerns among experts.

What are the characteristics of Stealth Omicron (BA.2) sub-variant of Omicron?

The most worrying thing about Omicron's sub-variant stealth is that this virus is not catching even in the RT-PCR test. Let us tell you that all the variants of coronavirus were confirmed only by RT-PCR test.

• According to the WHO, the symptoms of each variant of the corona are different from the earlier variants.

• Most infected people with Omicron complain of a runny nose or a prick in the throat and did not notice a loss of taste or aroma as in the previous variants.

• Symptoms such as sore throat, runny nose, headache, tiredness, sneezing may occur

• According to WHO, research needs to be done for how dangerous BA.2 can prove to be.

• The sub-variant of Omicron is more affecting the lungs of BA.2 infected. According to experts, 5% to 40% infection has been seen on the lungs of patients.

• According to the information available till now, BA.2 strain has been found in 57 countries in the last 10 weeks.

Maria Van Kerkhove, COVID-19 technical chief at the WHO, has said that there may be several sub-variants of Omicron that we are tracking. In Europe, cases of Kovid are increasing continuously in Armenia, Azerbaijan, Belarus, Georgia and Ukraine.

What should be done if the report comes negative after being infected?

Most importantly, if you have common symptoms of Omicron such as cold, cough and fever, do not ignore it. If the report comes negative even after seeing such symptoms, then get the test done again after 1 day or 2 days. If symptoms are visible and the report is negative, then it is important for you to isolate yourself. However, at the same time, doctors say that the BA.2 sub-strain is not more lethal than the BA.1 sub-strain of the micromicron. There is a slight difference in the form of both. Giving information, Professor of Community Medicine of AIIMS, Dr. Sanjay Rai has said that there are not only these two sub-strains of Omicron, but there are many sub-strains. The BA.2 strain was also identified a few days after Omicron's infection began. These two sub-strains are very contagious in the same way but there is no difference in disease severity.
