Abstract

BACKGROUND: Anthrax is a zoonotic disease caused by Bacillus anthracis, a gram-positive, spore- forming bacillus. Several cases of anthrax have been reported in Korea; it occurred as an outbreak after ingesting raw meat of an anthrax-infected cow. Among those reported cases, most of them were of gastrointestinal anthrax and a case report of cutaneous anthrax was also included. An outbreak of anthrax occurred in a village of Chang-Nyeong, Kyoungsangnamdo, Korea on July, 2000. The source of infection was the meat of an infected cow. We investigated clinical features and epidemiologic characteristics of the outbreak.
METHODS
Subjects were inhabitants and visitors who were exposed to the contaminated meat by ingestion or handling. Diagnosis and classification of clinical forms of anthrax were done according to the CDC case definition. A group of investigators composed of epidemiologists and medical doctors visited the village, and examined the residents and visitors exposed to contaminated meat by interviewing with standard questionare and physical examination.
RESULTS
Among 40 persons who contacted meat by ingestion and/or handling, 5(12.5%) developed cutaneous anthrax and 2 of them died; 4 were confirmed cases and 1 was suspected case. B. anthracis was isolated from the vesicular lesions of hands or forearms in those 4 confirmed cases and, in one patient who died of meningitis, the organism was also isolated in blood culture. All patients were of cutaneous anthrax, 3 were recovered and 2 died due to complications : one of meningitis and the other of intracranial hemorrhage. All 40 people consumed meat in cooked state not in raw. No anthrax occurred in 28 persons who only ingested cooked meat without any contact with the raw meat. Five cases of cutaneous anthrax were developed among those 12 persons who handled raw meat in preparation for cooking.
CONCLUSION
Anthrax should be suspected in patients with cutaneous lesions of vesicle or eschar on their exposed area after contacting animals or animal products, especially in an outbreak.
