variants (of SARS-CoV-2)

Variants of SARS-CoV-2 are versions of the virus that have slight genetic differences, usually caused by mutations. These changes can affect how the virus spreads, the severity of illness, or how well vaccines and treatments work. Some variants become more common if they have advantages, like being more contagious. Scientists closely monitor these variants to understand their impact and adapt public health responses accordingly. While many mutations are minor, significant variants are studied to ensure they don’t pose increased risks. Overall, variants are a natural part of virus evolution and help us learn to manage the disease better.
