Ciguatera fish poisoning tied to painful sex

NEW YORK - In a new report, public health investigators describe a cluster of ciguatera fish poisoning cases in which one of the main symptoms was painful sexual intercourse.

Ciguatera is a neurotoxin that may contaminate certain predatory ocean fish, such as barracudas, groupers and moray eels, the investigators note in this week's Morbidity and Mortality Weekly Report. Humans develop ciguatera poisoning when they eat the fish contaminated with the ciguatoxin, which is very heat-resistant and can't be destroyed by conventional cooking. Up to 50,000 cases of ciguatera fish poisoning occur each year, and the problem is endemic in tropical and subtropical areas of the Indian Ocean, Caribbean and Pacific basin.

Symptoms of ciguatera fish poisoning typically include gastrointestinal symptoms, such as nausea, vomiting, abdominal cramps or diarrhea. Neurologic symptoms, however, may also be present and include reversal of hot and cold sensation, fatigue, muscle pain, itching, and tingling. Of the seven patients who were sexually active, six complained of painful sexual intercourse, the report indicates.

The two men in this group described painful ejaculation, and the four women reported "a burning sensation during intercourse and 15 minutes to three hours after intercourse." One of the men reported that the effect lasted for one week, and two of the women said they were affected for one month.
