A new case of coronavirus BF.7 variant was reported in Karachi on Tuesday, reported 24NewsHD TV channel.

The health sources revealed that a case of Omicron sub-variant BF.7 was emerged in Karachi. 

The current surge in Covid-19 infections in China is believed to be driven by the BF.7 sub-variant of Omicron. But this isn’t the first time that BF.7 has made news — in October, it started to replace the variants that were then dominant in the United States and several European countries.

Sources said the variant was detected after sequencing of the virus. 

This is the first case of BF.7 variant in Pakistan.

The symptoms seen in individuals infected with this variant are fever, cough, sore throat, runny nose and fatigue.

Generally these symptoms are that of mild 'flu'. However, occasionally some people do get severe symptoms like breathlessness, coughing, fatigue and low oxygen level.

The BF.7 accounted for more than 5% of US cases and 7.26% of UK cases in October.
