Doctors advise dengue preventive measures

ISLAMABAD: The medical experts have advised the citizens to take special preventive measures to protect themselves against the dengue virus.According to them, the citizens should properly dispose off the solid-waste and stop water storage practices at their residences to prevent access to egg-laying female mosquitoes. They said that the mosquitoes breed primarily in containers like earthenware jars, metal drums and concrete cisterns used for domestic water storage, as well as discarded plastic food containers, used automobile tyres, and other items that collect rain water. Wasim Khawaja from Pakistan Institute of Medical Sciences (PIMS) said that dengue is a mosquito-borne infection, which in recent years has become a major public health concern.He said dengue fever is a severe, flu-like illness that affects infants, young children and adults. He added that the spread of dengue is attributed to expanding geographic distribution of the four dengue viruses and of their mosquito vectors, the most important of which is the predominantly urban species aedes aegypti. He said that the rapid growth of urban population is bringing ever greater numbers of people into contact with this vector, especially in areas that are favorable for mosquito breeding like where household water storage is common and where solid-waste disposal services are inadequate.He said that after the virus incubation for eight to ten days, an infected mosquito is capable, during probing and blood feeding of transmitting the virus to susceptible individuals for the rest of its life. He said that the virus circulates in the blood of the infected humans for two to seven days, at approximately the same time as they suffer from fever. He added that the clinical features of dengue fever vary according to the age of the patient.
