Coronavirus Variants and Mutations
- Coronavirus variants arise from mutations during virus replication, sometimes leading to significant behavioral changes.
- Some mutations enhance transmissibility or immune evasion, raising concerns.
Increased Transmissibility of UK Variant
- The UK variant is estimated to be 50% more transmissible, potentially leading to exponential growth in cases.
- Even a small increase in transmissibility can drastically increase infections over time.
Mitigating Variant Spread
- Increase vigilance by wearing masks, social distancing, and reducing shared indoor air time.
- These measures remain crucial for controlling the spread of all coronavirus variants.
