COVID Variants Raise New Challenges For Health Care Workers

The video discusses the impact of two coronavirus variants: the UK variant B117 and the South African variant E484K. The UK variant is more contagious but not more deadly, with cases documented in several US states. The South African variant has not yet appeared in the US but is present in other countries and may affect vaccine efficacy. Testing is ongoing to understand how these variants interact with vaccines and antibodies. Despite concerns, the care for COVID-19 patients remains unchanged.
