COVID-19 Surge In China: Omicron Subvariant BF.7 Symptoms To Watch Out For

3rd Edition of HealthCare Heroes Awards 2023

China has recently seen a surge in the number of COVID-19 cases, leaving offices and public places shut, and much of it is due to the highly infective Omicron subvariant BF.7. Like other COVID-19 variants, BF.7 can also be serious for people who have a weak immune system. The symptoms of Omicron subvariants BF.7 are linked to the symptoms of other Omicron subvariants, which include fever, sore throat, cough, and fatigue.

What Is Omicron Subvariant BF.7?

After its emergence in 2021, Omicron has evolved into a number of subvariants, one of which is BF.7. This subvariant is in the sub-lineage of the Omicron variant BA.5, which spreads faster than other variations, and has a shorter incubation time. This variant has a higher capacity to escape the immune system, implying that it can infect people who have been already infected by COVID-19 or have been vaccinated or both.

Its shorter incubation period and high transmission rate explain the reason for the surge China has been experiencing recently. A study has shown that Omicron's average R0 value (basic reproduction number) is 5.08, and it is believed that this value for BF.7 averages around 10 to 18.6. This implies that a person infected with this variant can transmit the virus to at least 10 to 18.6 other people.

Health experts suggest that around 60% of China's population could be infected with the virus, and over two million people could lose their lives.

Omicron Subvariant BF.7 Symptoms

The symptoms of Omicron subvariant BF.7 are linked to the symptoms of other Omicron subvariants, which are related to issues in the upper respiratory system. The symptoms to watch out for are as follows:

  • Fever
  • Cough
  • Sore Throat
  • Runny Nose
  • Fatigue
  • Gastrointestinal issues like vomiting and diarrhoea in some people
 

Like other COVID-19 variants, BF.7 can also be serious for people who have a weak immune system.

Bottomline

Since Christmas and New Year are approaching, public places are likely to see a high footfall, increasing the likelihood of spreading the virus. Thus, it is crucial to avoid unnecessary movement in crowded places. In case a need arises to move out of the house, wear a mask and follow social distancing.
