BF.7 (also known as BA.2.75.2) is a sub-lineage of the Covid Omicron variant BA.5.2.1.
The latest surge in global Covid cases, majorly driven by the Omicron sub-variant BA.5, may be causing increasing reinfections, meaning more people are catching Covid-19 for the second or third time, according to a media report.
New Zealand is currently under the orange settings of the Covid-19 Protection Framework, where there is no limit for gatherings.
Unlike the Delta variant, previously considered to be the main variant of concern in most countries, the dynamics of the Omicron variant showed different characteristics, they said.

The New York State Health Department identified two contagious variants having evidence of community spread. The sub-variants detected in Delhi, Haryana, Tamil Nadu, Maharashtra etc
According to WHO, the SARS-CoV-2 virus continues to evolve. With such intense transmission worldwide, further variants, including recombinants, will emerge. This is expected."
Both BA.4 and BA.5 have also been added to the UK agency's monitoring list. One case each of BA.4 has already been detected in Scotland and England, up to March 30, according to the UKHSA.
