Dengue emergency has been imposed in twin cities of Rawalpindi and Islamabad owing to outbreak of dengue epidemic.
According to media reports the number of dengue patients has reached alarming proportion surpassing 450 in the twin cities while over 500 dengue patients have been reported in the private hospitals and clinics.
The heads of several departments will be changed if dengue is not contained within 8 to 10 days.
The deputy commissioners have directed the management of hospitals to increase dengue wards immediately.
Third party report has declared both sides of Nullah Leh and the areas located at confluence of Rawalpindi and Islamabad as dengue affected areas.
Dengue epidemic has erupted in twin cities after Eid-ul-Azha. Under the directives of deputy commissioner Muhammad Ali Randhawa, spray has been stated on emergent basis in affected areas.
Health experts on Friday asked citizens of twin cities of Rawalpindi and Islamabad to properly dispose of solid waste and stop water storage practices at their residences to prevent the breeding of dengue.
According to them, 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 rainwater.
Dr Khawar Sultan from the Pakistan Institute of Medical Sciences (PIMS) said that dengue viruses were transmitted to humans through the bites of infective female Aedes mosquitoes. He added that mosquitoes generally acquired the virus while feeding on the blood of an infected person.
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 the clinical features of dengue fever vary according to the age of the patient. He said that dengue haemorrhagic fever is a potentially deadly complication that was characterised by high fever, haemorrhagic phenomena.
He added that the rapid growth of the urban population is bringing ever greater numbers of people into contact with this vector, especially in areas that are favourable for mosquito breeding such as households where water storage is common and where solid waste disposal services are inadequate.
