How to be sure that you have an Omicron BF.7 infection?
Symptoms can often be very vague. In fact, it has been found that COVID tests do not detect the exact strain. After the first strain of Omicron was detected, sub variants of Omicron quickly emerged, with BA.2 becoming the most prevalent strain in the spring and BA.5 becoming the most common by late summer. Later in the fall, B.Q.1 and B.Q.1.1 merged to become the most common forms of the virus in America. There are numerous omicron sub variants out there besides BA.5. These include XBB and BF.7, and yes, even BA.5.
Omicron BF.7: How effective is the double- vaccination against Omicron BF.7?
The Omicron variants are super-infectious and can cause re-infection in many patients. Even people who have been immunized against COVID through double vaccination are at risk of infection from Omicron BF.7.
The reason why this happens has been found. The BF.7 mutant exhibits 4.4-fold stronger neutralization resistance than the original Wuhan virus, as reported in a study published in the journal Cell Host and Microbe. As a result, the COVID vaccine's protective antibodies are ineffective.
Will the new booster doses protect you from the omicron sub variants?
During the first omicron wave, people who were up-to-date on their original COVID shots had less severe symptoms. However, a revised Covid booster, which interferes with the BA.4 and BA.5 subvariants' spike proteins, was approved by the FDA in August.
It was later discovered that the updated booster dose is also effective against the 2019 Wuhan virus strain that was first discovered. A CDC report confirmed that updated vaccine boosters, especially for those 65 and older, were more beneficial than the original vaccine booster at reducing hospitalization. This revised booster was approved for use in December, and it is now recommended for children older than 6 months.
Omicron cases in India
Dr. V. K. Paul, a member of India's NITI Aayog who focuses on health policy, reports that about 27–28% of the population has received the COVID-19 preventative shot so far. Recently, the number of COVID-19 cases reported from China, Japan, South Korea, France, and the United States has gone up in a scary way. In India 4 cases of Omicron BF.7 infections have been discovered.
