Covid-19: What We Know About BF 7 & XBB 1.5 Corona Variants

Many individuals are concerned about which variation is the most harmful in India and how their symptoms differ from old covid variants. Therefore, let’s discuss XBB.1.5 strains and Omicron BF.7 variants.

New variants of the omicron coronavirus BF.7 have been identified in China, and XBB1.5 have been identified in the United States (USA). According to data and research, over 40 percent of new COVID-19 cases in the United States belong to the new super variant XBB1.5 strain.

BF 7 or BF.7

BF 7 is a mutation of omicron BF.5. BF.7 has a mutation in the spike protein gene. And since last month, these new omicron variants BF.7 or BF 7 are rapidly spreading in China, infecting many people.

It is still unclear where this variant of omicron originated, but it is spreading rapidly in China.

XBB 1.5 Variant

Super variant XBB.1.5 of Corona is a subtype of XBB. Multiple models show that the transmission R-value and infection rate of the XBB1.5 variant are significantly worse than prior variants; hence, this strain is also known as the super variant. A novel recombinant strain, XBB1.5, is more immune-evasive and infectious than BQ and XBB corona variants.

Why are XBB1.5 and BF 7 variations different from old variants?

1. XBB1.5 and BF 7 spread significantly more rapidly than their previous versions.

2. XBB1.5 & BF 7 are the most immunity-evasive variations.

3. XBB1.5 and BF 7 are more infectious than their predecessors.

4. XBB1.5 and BF 7 individuals with weakened immune systems and pre-existing medical issues are more likely to suffer serious diseases.

Symptoms of XBB1.5 & BF 7 corona variants

1. High Temperature (Fever)

2. Sore throats

3. Runny nose

4. Cough

5. Diarrhea

XBB1.5 strains & BF 7 Variants in India

There are already XBB1.5 and BF 7 cases in India. In Gujarat, India verified its first case of Omicron variant XXB.1.5. According to health experts, India has few cases; XBB1.5 and BF 7 have been present in the country for some time, but they have not caused an outbreak. Consequently, based on the data, India is doing well.
