In ten large cities, the climate is perfect for a dengue outbreak

The Pakistan Meteorological Department (PMD) has warned of the possibility of a dengue outbreak in ten major cities and flood-affected areas due to climatic conditions in the post-monsoon season, according to The News on Saturday.

According to the PMD, atmospheric factors provide optimal circumstances for mosquito multiplication and, as a result, the spread of vector-borne diseases, as evidenced in previous data analysis and climate forecast.

“Based on the analysis, the atmosphere has become suitable for dengue outbreak next month, particularly in 10 major cities, including Karachi, Lahore, Peshawar, Rawalpindi, Islamabad, Hyderabad, Faisalabad, Sialkot, Larkana, and Multan,” the meteorological service said in a Friday advisory.

It went on to say that dengue fever has spread and afflicted people in the country over the last ten years, with the problem peaking during the post-monsoon season, which runs from September 20 to December 5, assuming conditions are favourable.

“The dengue thrives at 26-29°C temperatures and 60% humidity, as well as more than 27mm rainfall with a maximum time lag duration of 3 weeks,” according to the PMD advisory.

The active period for dengue attacks is two hours after sunrise and two hours before dusk, and breeding ceases when the temperature drops below 16°C, according to the advisory.

The PMD asked stakeholders to adopt preventative measures against the dengue epidemic in the districts, and noted that national health agencies and dengue control organisations will be involved.
