Varicella (Chickenpox) in Florida
Florida HealthDisease Control
May Key Points
highest incidence rate
unknown vaccinations status
The number of varicella cases reported in May 2022 decreased from the previous month and was below the previous 5-year average. Due to robust vaccination programs, there is no longer discernable seasonality for varicella cases.
In May 2022, 45 varicella cases were reported in 21 counties, outlined in black in the map. From March 2022 through May 2022 the average county rates varied throughout the state.
In 2022, 191 varicella cases were reported.
The annual number of reported varicella cases increased from 2017 to 2019 and decreased significantly in 2020 and 2021.
In May, the varicella rate was highest among infants <1 year old at 1.7 cases per 100,000 population, which is consistent with previous months. infants <1 year old are too young to receive varicella vaccination, which is why vaccination of siblings, parents, grandparents and other age groups is important in infection prevention among infants.
In May, 2 cases were transmitted within households and no cases were outbreak-associated. For most varicella cases, exposure to other known cases is not identified. In Florida, transmission setting is not routinely identified for non-outbreak cases, resulting in 82% of cases reporting unknown setting in May.
People with shingles infection can transmit the virus that causes varicella to people without immunity. In May, 4 cases reported having contact with someone diagnosed with shingles during their exposure period.
