    We analyzed a potential relationship between changes in school absences in Sarasota County and Karenia brevis (Kb) count data. Brevetoxins released during Kb blooms could be a reason for students experiencing increased respiratory or gastrointestinal illnesses, causing an increase in absence rates. We designed a map to relate the locations of Sarasota County schools and the distributions of those Kb counts with a minimum of 10,000 cell counts per liter and above. Due to the proximity of Kb counts, we hypothesized that brevetoxins could have a greater effect on the schools near the coast of Florida rather than the schools inland. Because individuals could be affected by brevetoxins up to several days after being exposed, we expected to find a lagged effect of a bloom occurrence on school absences. Using a regression approach, we were unable to detect an association between Kb counts and student absences. In some cases, the direction of the effects were opposite to what would be expected (i.e., an increase in Kb counts was associated with a reduction in the percent absent rate). The results indicated that over 70% of the variation in the school percent absent rate could be explained by the latent characteristics of individual schools (such as variations in student populations across different schools), by school week, by month (such as the effects of flu outbreaks or and other seasonal factors), and by year.

    The neurological effects of Florida Red Tide (FRT) blooms [poster]

    Karenia brevis is a marine dinoflagellate responsible for Florida red tide (FRT) blooms off the west coast of Florida. K. brevis contains brevetoxins, a neurotoxin that is absorbed by shellfish as well as released into the air. Brevetoxins are known to cause disruptions in normal neurological functions and are associated with neurotoxic shellfish poisoning (NSP). Previous research has emphasized the effect of FRT blooms on human health, from gastrointestinal to respiratory illnesses. However, there has been little research examining the effect of FRT blooms on neurological illnesses. There is research highlighting the biochemical effects of brevetoxins on mammalian nervous systems, so these symptoms can be matched to hospital codes that describe a hospital patient’s affliction. With these hospitalization codes, it is possible to study the relationship between FRT blooms and the occurrence of neurological illnesses in affected counties. The hospital data consists of inpatient data from 1988-2010 and emergency room data from 2005-2010. We will also use data containing K. brevis cells per liter as a measure of red tide occurrences.
