August Key Points
unknown vaccination status
The number of varicella cases reported in August increased from last month and was above 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 83 varicella cases in August were reported among the 23 counties outlined in black. From June through August 2019 the average county rate varied throughout the state.
From January 1, 2019 through August 31, 2019, 671 varicella cases were reported in 53 counties.
The annual number of reported varicella cases decreased from 2015 to 2017. Year-to-date cases counts as of August 2019 are higher than those seen at this time in previous years, as noted by the white bar in the figure.
In August, 17 (20%) of 83 total cases were associated with transmission within households and 11 (13%) 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.
One varicella outbreak was reported in August. This outbreak was reported in a detention facility in Miami-Dade County and as of the end of August 2019, consists of 11 cases.
So far in 2019, only one varicella outbreak has been reported.
