Two years into the COVID-19 pandemic, and just when new cases and hospitalizations in the U.S are on the decline, an Omicron subvariant called BA.2 is gaining significant traction in some parts of the world. Dr. Monica Gandhi, an infectious disease specialist and professor of medicine at the University of California, San Francisco explains what we know about it.
The government has confirmed it is investigating the BA.2 variant of Omicron, but due to its specific mutations, it is proving to be harder to track.
At this point of the COVID-19 pandemic, with the highly transmissible Omicron variant, it may be an all-too-familiar story: You know of a fully vaccinated household where some people tested positive for COVID — and others in the same household never tested positive at all.

A new year is upon us, and with it, more discoveries as scientists race to fully understand potential threats the Omicron variant poses. Dr. Monica Gandhi, infectious disease specialist and professor of medicine at the University of California, San Francisco, sheds light on what is known about Omicron's transmissibility and severity and how current COVID-19 vaccines fare at preventing severe illness from the variant.
The government has continued to resist calls to slash the isolation period after testing positive for COVID-19 to five days.
Modelling by experts at Warwick University suggests there could be 2,890 deaths per day by mid-January under current 'Plan B' restrictions.
