What is the Florida Red Tide?
Florida’s infamous red tide, also known as Karenia brevis, is a catastrophic type of harmful algae bloom (HAB) that occurs in the Gulf of Mexico. These blooms contain microscopic marine algae, which tint the water red, brown, or green. While numerous species are capable of creating a red tide,‘ it is predominantly the bacterium named after its home state, Karenia brevis, that does it here.
Dangers of Red Tide
The poisonous algae that causes the red tide releases potent neurotoxins known as brevetoxins, which can be harmful to marine life, resulting in large fish kills and the deaths of sea turtles, birds, dolphins, and manatees. Even after these organisms die and their cells degrade, the toxins stay in the water and can become airborne through smashing waves.

Risks for Humans from Red Tides
Respiratory irritation: Brevetoxins in the air can induce coughing, sneezing, and burning in the eyes, nose, and throat, especially in patients who already have asthma or COPD.
Neurological symptoms: In severe circumstances, eating contaminated seafood or inhaling airborne contaminants can cause neurological symptoms like headaches, dizziness, disorientation, and even seizures.
Shellfish poisoning: Consuming shellfish infected with brevetoxins can result in neurotoxic shellfish poisoning (NSP), which causes severe gastrointestinal and neurological symptoms.

Why Immunocompromised People Should Be Extra Cautious?
Immunocompromised people, especially those with reduced immune systems owing to sickness, aging, or medical treatments, are more likely to suffer serious health consequences from red tide exposure. Consuming contaminated seafood may increase their susceptibility to respiratory irritation, neurological problems, and infections. As a result, these people must take special measures during a red tide episode.
Conclusion
Florida’s red tide is a fascinating natural occurrence, but it may also be harmful, particularly for immunocompromised people. Staying informed, avoiding vulnerable locations, and taking essential steps can help you limit your chance of exposure and stay safe during a red tide event.
