Viruses are constantly changing to create new variants. Some changes and mutations allow the virus to spread more easily or make it resistant to treatments or vaccines. As the virus spreads, it may change and become harder to stop. Even if an infection caused by a particular variant is less likely to cause severe disease compared to other variants, an increase in the total number of cases could cause an increase in hospitalizations, put more strain on healthcare resources, and potentially lead to more deaths. CDC is working with many public health officials and partners to monitor all variants.
