February Key Points
unknown vaccinations status
The number of varicella cases reported in February 2023 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 the United States of America.
In February 2023, 37 varicella cases were reported in 16 counties, outlined in black in the map. From November 2022 through January 2023 the average county rates varied throughout the state.
In 2023, 81 varicella cases were reported. The annual number of reported varicella cases increased from 2018 to 2019 and decreased significantly in 2020 and 2021.
In February, the varicella rate was highest among <1 year olds at 0.85 cases per 100,000 population. 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 February, 3 cases were household-associated 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 62% of cases reporting unknown setting in February.
People with shingles infection can transmit the virus that causes varicella to people without immunity. In February, 3 cases reported having contact with someone diagnosed with shingles during their exposure period.
