The severity of symptoms varies, but most cases have been reported as mild. XEC doesn’t seem to cause more severe illness than previous variants.
Transmission and Spread
XEC spreads through respiratory droplets, similar to other COVID-19 variants. Its transmissibility is still being studied, but it appears to spread easily, especially in crowded indoor spaces.
Vaccine Effectiveness
Current COVID-19 vaccines are expected to remain effective against XEC in preventing severe disease. However, ongoing studies are assessing the variant’s potential impact on vaccine effectiveness.
