Omicron Sub-Variant BF.7: Concerns & Symptoms To Watch Out For

Recently, India’s first case of Omicron’s BF.7 was reported by Gujarat Biotechnology Research Centre. It is believed that this sub-variant has transmissibility. Experts are of the opinion that the sub-variant BF.7 and BA.5.1.7 are behind the recent surge of COVID-19 cases in China.

Concerns About BF.7 Sub-Variant

After emerging from Mongolia, the BF.7 sub-variant is now posing fresh threats to the United States, United Kingdom, Belgium, and Australia. It has come to light that this variant has a high propensity to evade the immune system and can even infect fully vaccinated people.

Health experts say that only a few viral particles can cause infection in someone. This implies that in contrast to the earlier variants, which required far greater exposure, this variant can cause infection even with little exposure to the infected person.
