March Key Points
unknown vaccination status
The number of varicella cases reported in March decreased from last month and was below the previous 5-year average. Due to robust vaccination programs, there is no longer a discernable seasonality for varicella cases in the United States.
The 32 varicella cases in March were reported among the 19 counties outlined in black. From January 2020 through March 2020 the average county rate varied throughout the state.
From January 1, 2020 through March 31, 2020, 189 varicella cases were reported in 42 counties.
The annual number of reported varicella cases decreased from 2015 to 2017. In 2020, case counts were similar to those seen in previous years, as indicated by the white bars in the graph.
In March, 5 (16%) of 32 total cases were associated with transmission within households and no cases were outbreak-associated. For most varicella cases, exposure to other known cases is never identified, and they are not able to be linked to outbreaks.
No varicella outbreak was reported in March.
