Eleven districts of Bengal, mostly in the northern part of the state, have reported at least 65 cases of black fever, also called 'kala-azar', in the last couple of weeks, a senior official of the health department said on Friday, citing results of state-administered surveillance.
Districts, where a maximum number of cases was recorded, include Darjeeling, Malda, Uttar Dinajpur, Dakshin Dinajpur, and Kalimpong, he told PTI. "Kala-azar was practically eradicated from West Bengal. Recent surveillance, however, led to the detection of 65 cases in 11 districts. Now that these cases have been detected, the state will be able to tackle the spread of the disease,” the official said.
The districts of Birbhum, Bankura, Purulia, and Murshidabad have also reported a few cases of black fever, mainly transmitted by bites of sandflies infected with the parasite Leishmania donovani. According to the official, no case was detected in Kolkata thus far.
"It was found that the disease was most prevalent in people who have spent a considerable amount of time in Bihar, Jharkhand, and Uttar Pradesh. Some individuals from Bangladesh, too, have been showing symptoms of kala-azar," the official said, adding that the surveillance process will continue. A top bureaucrat at the state secretariat said that the government has taken the decision to treat all diagnosed with the disease "free of cost".
"Even if the infection is detected in a private laboratory or hospital, the doctor should immediately bring the matter to the attention of the district health officer. All expenses of treatment along with meals will be borne by the state health department. The district chief health officer will monitor the whole matter," the bureaucrat told PTI.
Arrangements are also being made to provide nutritious food to the patients, he added.
