Community-level initiatives:
- Public awareness campaigns: Educate communities about dengue prevention, early detection, and seeking medical care.
- Vector control activities: Implement fogging, larviciding, and other mosquito control measures in collaboration with local authorities.
- Improved sanitation: Advocate for and participate in initiatives to improve sanitation infrastructure and practices.
National Dengue Surveillance System
Considering escalating dengue cases, Pakistan’s Ministry of Health established a National Dengue Surveillance Cell in 2010 and a Dengue Expert Advisory Group in 2011 to facilitate surveillance coordination and outbreak responses.
Additionally, a national integrated dengue surveillance system collects data from District Health Authorities to monitor long-term trends nationwide. Information flows from health institutions to field epidemiologists, district authorities, provincial units, and finally, central analysis.
This data captures details like geographical spread, frequency, demographics affected, and deaths. It enables observing relative seasonality and high-risk areas for targeted prevention and control planning.
Current Status of Dengue in Pakistan
In 2022, over 37,425 dengue cases and 92 related deaths occurred countrywide. National Dengue Control Comparatively, 2019 saw 50,161 cases, while 2020 reported 23,849 during COVID-19 pressures on health infrastructure limiting outbreak responses.
The 2022 data until December shows the seasonal caseload peaking in October across Pakistan after the post-monsoon period, fostering ample mosquito breeding grounds.
The majority of cases occurred in Sindh at 22,964, followed by Punjab at 10,711. Karachi and Lahore saw 11,540 and 8,342 cases, respectively. Islamabad’s capital area saw 3025 instances. September-November remain peak months historically for dengue incidence in Pakistan’s tropical climate.
When Will The Dengue Season End in Pakistan?
Dengue transmission season in Pakistan generally spans the warmer monsoon months between September to November. National Dengue Control Cases begin rising in August, hit a peak in October, and start declining by December as temperatures cool.
By January to March, viral transmission tapers off across most regions of the country. However, warmer city areas and southern coastal regions maintain breeding cycles that enable a few sporadic cases even in cooler months.
Overall, December through February represent minimal transmission periods before the cycle begins again post-March. National Dengue Control Disease surveillance data over the past decade clearly maps out this seasonal dengue pattern in Pakistan.
Authorities hope ongoing control measures will help flatten incidence curves and shorten high transmission periods in coming years.
Current Control and Prevention Strategies
Pakistan aims for comprehensive, integrated vector management by synergizing chemical, biological, and educational tactics.
Key initiatives include:
- Larvicidal spraying of water bodies using temephos
- Space spraying pyrethroid insecticides
- Distributing larvicide chemicals and cleaning agents
- Fish introduction in water reservoirs
- Promoting protective clothing, nets, and repellents
- Awareness campaigns for community participation
- Establishing improved disease monitoring and reporting
The Dengue Expert Advisory Group routinely advises updating diagnostics, treatment protocols, and surveillance systems per evolving epidemiology.
