ISLAMABAD: The dengue outbreak is likely to occur in 10 major cities across Pakistan including Karachi and Lahore in month of October.

The Pakistan Metrological Department said that dengue may see a significant rise in October, particularly in ten major cities across Pakistan, including Karachi, Lahore, Peshawar, Rawalpindi, Islamabad, Hyderabad, Faisalabad, Sialkot, Larkana, and Multan.

The other regions affected by post-monsoon rainfall are also at risk.

The dengue fever has severely impacted the health of population, particularly during the post-monsoon season.

The period from September 20 to December 05 has become increasingly dangerous for dengue spread, with environmental factors playing a significant role.

According to the PMD, dengue transmission is triggered when temperatures remain between 26 C and 29C for three to five weeks, with humidity levels of around 60 percent.

Similarly, rainfall exceeding 27mm, combined with a time lag of up to three weeks, further increases the risk.

The disease-carrying mosquitoes are most active two hours after sunrise and two hours before sunset, with breeding coming to a halt only when temperatures drop below 16 C.

Based on a detailed analysis of historical data and the current climate outlook, the PMD experts have warned that conditions have become highly conducive to dengue onset since mid-September.

The PMD has urged all relevant stakeholders, including national health agencies and dengue control centers, to take immediate preemptive measures in the affected districts.
