KARACHI - Health experts have warned the provincial government against the possible outbreak of dengue in August and September, keeping in view the forecast of heavy rainfall.

They have vigorously advised the citizens to prevent themselves from mosquito bites by using repellents, insecticides, and wearing proper dresses. They urged the authorities concerned to remove stagnant water from the streets and other areas of the city because water activates breed mosquitoes, causing dengue fever and malaria.

Talking to TheNation, Pakistan Medical Association (PMA) central leader Dr S M Sajjad Qaiser pointed out that August and September are very important in connection with dengue fever as these two months are specific for the breeding of mosquitoes. He maintained that the rainy season creates new breeding pools, while the breeding of mosquitoes could multiply if the water of these pools was not drained properly. The temperature from 22 to 30 degree centigrade helps in breeding of mosquitoes, he added.

It is pertinent to mention here that dengue mosquito bites during the day, lives indoors in domestic settings and breeds in both clean and polluted water, while adult mosquito is destroyed in temperature beyond 38 C. The eggs can withstand desiccation and can hatch next year as well whenever conditions are conducive.

Dr Sajjad praised efforts of the Sindh government during last year. He urged the citizens to help the government in term of eradicating deadly mosquitoes from the city. He said that proper fumigation drive is need of the hour to stop spread of the fatal disease.

As per WHO, “dengue is transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses. It occurs in tropical and sub-tropical areas of the world. Symptoms appear 3—14 days after the infective bite. Dengue fever is a febrile illness that affects infants, young children and adults.

Symptoms range from a mild fever, to incapacitating high fever, with severe headache, pain behind the eyes, muscle and joint pain, and rash. There are no specific antiviral medicines for dengue. The incidence of dengue has grown dramatically around the world in recent decades. Some 2.5 billion people – two fifths of the world’s population – are now at risk from dengue. WHO currently estimates there may be 50 million dengue infections worldwide every year. A senior official of Dow University of Health Sciences, Ojah Campus, Dr Qutbudeen said that dengue fever is a largely urban phenomenon, which starts from August and gets momentum in September and October.

As per the report of the Provincial Dengue Surveillance Cell of Sindh Health Department, issued on Saturday, as many as 138 cases have been reported in the city during the ongoing year. Out of the total cases, 136 cases were found positive with the virus. As per the report, as many as 83 patients have been admitted to various hospitals in the City, while three patients are still housed in various health facilities. Two more new confirmed dengue cases have been reported on Saturday in the City.
