ISLAMABAD: The Provincial Disaster Management Authority (PDMA) on Monday warned of a “severe” dengue outbreak in major cities of the eastern Punjab province along with those areas affected by floods, urging district administrations, health officials and the public to take pre-emptive measures against the disease.

Dengue is a viral infection caused by the dengue virus, which is transmitted to humans through the bite of infected mosquitoes. While many dengue infections are asymptomatic or produce only mild illness, the virus can occasionally cause more severe cases, and even death.

Floods in Punjab have killed 104 people since late August, affected over 4.5 million people and displaced more than 2.5 million. Authorities say they have launched the largest search and rescue operation in the province, as floodwaters recede and head toward the southern Sindh region.

In its latest alert, the PDMA Punjab warned that favorable weather for the virus and flood-related waterlogging have made conditions conducive for the onset of dengue from Sept. 20 onwards.

“It is predicted that this season poses an unprecedently high-risk of a severe dengue outbreak, particularly in major cities, Lahore, Faisalabad, Sialkot, Rawalpindi and Multan as well as in flood affected areas across the Punjab,” the PDMA alert read.
