Although there is no known red tide in Delaware, this Health Advisory is sent to inform health care providers\n\n\n  about symptoms associated with red tide and to request that they report patients exhibiting symptoms suspected to have been caused by red\n\n\n  tide.\n\n\n<\/p>\n\n\n<p>\n\n\n  Red tides are caused by an increase in algae populations, often called a bloom. The preferred term for these events is <em>algal\n\n\n  bloom<\/em> as there may be colors other than red or no color at all associated with potentially harmful algae population in water. There\n\n\n  may also be events that cause a red tint to the water that are not associated with an algal bloom.\n\n\n<\/p>\n\n\n<h3>\n\n\n  Occurrence\n\n\n<\/h3>\n\n\n<p>\n\n\n  Red tides have been known to occur in most of the coastal regions of the world. Delaware experienced a red tide in late August and early\n\n\n  September, 2007, due to the presence of <em>Karenia brevis<\/em> \u2013 a naturally-occurring dinoflagellate (single-celled phytoplankton\n\n\n  with two flagella). This is the first documented occurrence of the organism north of Cape Hatteras, North Carolina. The organism is\n\n\n  primarily found on the Gulf Coast of Florida, and it is believed that an eddy from the Gulf Stream brought <em>K. brevis<\/em> to\n\n\n  Delaware\u2019s near-shore waters. Outbreaks, if they occur, will typically be seen from mid- to late-summer through early fall.\n\n\n<\/p>\n\n\n<h3>\n\n\n  Health Effects\n\n\n<\/h3>\n\n\n<p>\n\n\n  The most well documented health effect from exposure to a HAB is through consuming shellfish that have been contaminated by one of the\n\n\n  various species of algae responsible for red tides. Health effects can vary depending on the organism. The organisms that have been found\n\n\n  in Delaware can cause neurotoxic shellfish poisoning (NSP). NSP can include gastrointestinal and neurological effects including nausea\n\n\n  and diarrhea; dizziness; muscular aches; and tingling and numbness in the tongue, lips, throat, and extremities. Scientists know little\n\n\n  about how other types of environmental exposures to brevetoxin\u2014such as breathing the air near red tides or swimming in red\n\n\n  tides\u2014may affect humans. Anecdotal evidence suggests that people who swim among brevetoxins or inhale brevetoxins dispersed in the\n\n\n  air may experience irritation of the eyes, nose, and throat, as well as coughing, wheezing, and shortness of breath. Additional evidence\n\n\n  suggests that people with existing respiratory illness, such as asthma, experience these symptoms more severely. Contact dermatitis is\n\n\n  possible if a person swims or bathes in water containing high amounts of the organisms.\n\n\n<\/p>\n\n\n<h3>\n\n\n  Limiting Exposure\n\n\n<\/h3>\n\n\n<p>\n\n\n  The best protection is to avoid contact with contaminated waters and nearby areas, as well as the ingestion of fish and shellfish from\n\n\n  such waters.
