coronavirus variants

Coronavirus variants are versions of the virus that have slight genetic changes, called mutations. These mutations can occur as the virus spreads and multiplies. Some variants may spread more easily, cause different symptoms, or affect how well vaccines work. Scientists monitor these changes to understand their impact on public health. Not all variants are more dangerous, but tracking them helps us stay ahead in managing the pandemic. Overall, variants are a natural part of how viruses evolve, and ongoing research helps ensure our responses remain effective.
