How is red tide related to respiratory irritation?
People experience respiratory irritation (coughing, sneezing, and tearing) when the red tide organism (K. brevis) is present along a coast and winds blow its toxic aerosol onshore. CAUTION: People with severe or chronic respiratory conditions (such as emphysema or asthma) are advised to avoid red tide areas. Generally, symptoms are temporary. Once exposure is discontinued, symptoms usually disappear within hours.
