Red Tide: Overview and Clinical Manifestations.

Abstract

Harmful algal blooms occur when toxin-producing algae grow rapidly. These occur worldwide and have significant impacts on aquatic ecosystems and on human health. Specifically, the toxic blooms of Karenia brevis in Florida may affect humans via inhalation or ingestion. On retrospective reviews, health care costs appear to rise during these outbreaks because of respiratory and gastrointestinal manifestations. Treatment for exposure is supportive care, though traditional inhalers may help with respiratory complications.
