The health authorities have sounded caution on the prevalence of mosquito-borne diseases during the summer months. Ernakulam has reported a total of 239 dengue cases, of which 78 were confirmed cases in April. A case of malaria was reported from Thrikkakkara on April 25.
Mosquito-borne diseases, including dengue, chikungunya, West Nile fever, and malaria, continue to be reported in the district, said Dr. R. Shahirsha, District Medical Officer, Ernakulam.
“Although the incidence is lower compared to last year, vigilance remains crucial in preventing these diseases. Source reduction and preventing mosquito breeding sites must be prioritised. Along with this, observance of the mandatory ‘Dry Day’ is essential at homes and establishments,” he said.
He added that in the case of diseases such as dengue and chikungunya, transovarial transmission could spread the pathogen up to six generations, making source reduction a necessary part of daily life. “Even indoor plants kept in water can become breeding grounds, and they should be avoided. Regular screening for malaria among migrant populations in cases of fever is also important,” he said.
Dr. Reshmi Ramachandran, Associate Professor, Community Medicine, Government Medical College, Ernakulam, said malaria cases had been observed among migrant labourers.
