Florida's Respiratory Syncytial Virus Surveillance

A statewide Respiratory Syncytial Virus (RSV) surveillance system was implemented in Florida in 1999 to support clinical decision-making for prophylaxis of premature infants. RSV infections usually occur during the late fall, winter, or early spring months (CDC). Data collected by the Florida RSV surveillance system from 1999 - present allow us to identify geographical regions where high infection rates also occur during the summer month.

Data are collected weekly from 12 sentinel hospitals throughout Florida. Each site reports the total number of RSV tests performed and the total number positive to the Bureau of Epidemiology via email or fax. Regional and statewide data are made available to public health professionals, health care providers and the public via a website.

RSV activity typically peaks in the months of November through January and is least active in summer. Although summer months typically have less RSV activity in Florida, participating facilities, especially in South Florida, consistently report greater than 10% of laboratory tests as positive in most summer months.

The determination of unique seasonal and geographical trends of RSV activity has important implications as it relates to prescribing patterns for initiating prophylaxis to children at high-risk for RSV infection. The data obtained through RSV surveillance have proven to be a useful guide to Florida's healthcare professionals in understanding the unique seasonal and geographical RSV trends in Florida. This unique trend has also been validated by the CDC.

We really appreciate all of the quality data that our sentinel hospitals provide. If you would like further information regarding becoming a sentinel hospital please contact the Bureau of Epidemiology at (850) 245-4401.

For more information about regional or county specific respiratory disease activity please contact your local county health department.

Current Florida RSV Surveillance Information:

Recent changes to the Centers for Disease Control and Prevention's National Respiratory and EntericVirus Surveillance System (NREVSS) has led to a reduction in the number of hospitals participating inNREVSS. Those changes are reflected in the most recently published RSV tables and graphs. The FloridaDepartment of Health is reaching out to hospital laboratories to strengthen Florida's RSV surveillancesystem.

For the most recent trend information please view the final figure (Figure 25) in the Florida Flu Review.

RSV Surveillance Summary

Week 48: November 26 – December 2, 2017

Respiratory syncytial virus (RSV) activity:

Respiritory Syncytial Virus Surveillance Map
  • In week 48, the percent of children <5 years old diagnosed with RSV at EDs and
    UCCs decreased but remained well above levels observed in previous seasons at
    this time.
  • RSV activity this fall has remained higher than levels observed in previous seasons for several months in a row. All regions are currently in RSV season.

RSV seasonality:

  • RSV activity in Florida typically peaks in November through January, though activity can vary dramatically by region. According to CDC, the start of RSV season is marked by the first two consecutive weeks during which the average percentage of specimens testing positive for RSV is ≥10%.
  • Florida has established regular RSV seasons based on these thresholds.
  • Florida’s RSV season is longer than the rest of the nation and has distinct regional seasonality. For more information on RSV seasonality in Florida, see the American Academy of Pediatrics’ (AAP) 2015 Red Book.
