Human anthrax in India: urgent need for effective prevention.

ABSTRACT

Anthrax is a zoonotic illness caused by Bacillus anthracis. Sporadic cases continue to be reported from many parts of the world. From India, both sporadic cases and outbreaks are being reported regularly. The Union Territory of Pondicherry (a former French colony) lies on the coast of Bay of Bengal, where the incidence of anthrax is on the rise with 28 cases being detected in the year 1999 and 2000 alone. So far, about 34 human cases have been encountered in this region. Recently, an increase in the number of anthrax cases has been noted in veterinary and human practice in this area. Most cases have occurred in agricultural labourers who gave history of handling animal meat or skin of infected animals. The meningitic form of the disease has a very bad prognosis. Patients with this form of disease died despite treatment with high dose penicillin. The typical bacilli were seen in the CSF in all cases of anthrax meningitis and was diagnostic of the condition. The cutaneous form of illness had a benign course and responded favourably to penicillin treatment. Awareness among clinicians and mandatory reporting of cases to public health departments along with public education will help control morbidity and mortality due to anthrax. Effective immunization of animals is the other important control measure for anthrax.
