March Key Points
highest incidence rate
unknown vaccinations status
The number of varicella cases reported in March 2021 increased from the previous month and remained below the previous 5-year average. Due to robust vaccination programs, there is no longer discernable seasonality for varicella cases in the United States.
In March 2021, 26 varicella cases were reported in 16 counties, outlined in black in the map below. From January 2020 through March 2021 the average county rate was highest in Northwest Florida
In 2021, 63 varicella cases were reported in 26 counties. The annual number of reported varicella cases decreased from 2016 to 2017. In 2020 and 2021, case counts are lower than those seen in previous years at this time.
In March, 3 cases were transmitted within households and no cases were associated with an outbreak,. For most varicella cases, exposure to other known cases is not identied. In Florida, transmission setting is not routinely identied for non-outbreak cases, resulting in 58% of cases reporting unknown setting in March.
People with shingles infection can transmit the virus that causes varicella to people without immunity. In March, 7 cases reported having contact with someone diagnosed with shingles during their exposure period
