Though the Chikungunya epidemic that devastated Ratnapura district with over 10,000 reported cases brought misery and pain to many, it had been a windfall for private medical practitioners, a ministry spokesman said yesterday. "A survey conducted by the Ministry of Health for the sharp increase of Chikungunya has revealed the Epidemiologist Unit has not taken action to prevent the spread of the disease and has also failed to report the first case of Chikungunya where a pilgrim at Eratne had infected Chikungunya after he made a pilgrimage to India,' the spokesman said.
