Sindh is experiencing a significant dengue outbreak, as figures from major Karachi hospitals reveal over 12,000 cases in just six weeks. This number starkly contrasts with the 819 cases officially reported by the Sindh health department for the entire year. Consequently, health authorities are facing increasing scrutiny over the accuracy of their public health data. Meanwhile, this concerning situation highlights challenges in disease surveillance and response in the region.
Discrepancy in Sindh Dengue Cases Data
Official data released by the health services director general states 579 confirmed dengue cases in Karachi and 119 in Hyderabad this year. However, a wide gap exists between these government statistics and those compiled by major healthcare facilities. For instance, Indus Hospital, Liaquat National Hospital, and the Sindh Infectious Diseases Hospital and Research Centre together recorded 2,972 dengue cases between September 1 and October 16. Furthermore, Jinnah Postgraduate Medical Centre alone registered 1,062 cases since July. Similarly, Aga Khan University Hospital reported a spike in dengue cases, surpassing last year’s figures, along with several deaths. Data from the Diagnostic and Research Laboratory of Liaquat University of Medical and Health Sciences (LUMHS) in Hyderabad and its branches further corroborate the severity, showing 9,075 confirmed cases from September 1 to October 14.
PMA-Sindh President Bashir Ahmed Khaskheli emphasized that the situation is far more serious than official statistics indicate. He explained that there is no formal mechanism to gather feedback from private clinics, hospitals, and even informal practitioners. This absence of comprehensive data collection means many cases, especially among those with limited financial resources who bypass laboratory tests, remain unrecorded.
Factors Contributing to the Dengue Outbreak
Experts attribute the rise in Sindh dengue cases to poor drainage and ineffective fumigation efforts, particularly after heavy monsoon rains. When rainwater accumulates, it creates ideal breeding grounds for vectors like mosquitoes, increasing disease transmission. Mirza Ali Azhar of the PMA pointed out that standing water in ponds and inadequate sewerage systems contribute significantly to mosquito habitats. He also noted that few government fumigation drives have been conducted to control vector-borne disease spread.
Professor Faisal Mahmood, an infectious diseases specialist at Aga Khan University Hospital, confirmed the sharp increase in dengue cases, observing that October typically marks the peak of the dengue season. Moreover, he mentioned that dengue rates exhibit cyclic patterns over the past decade due to factors like weather and viral strain changes. He suggested that recent rain floods likely played a role in this year’s surge. Similarly, LUMHS Dean of Medicine Imran Shaikh highlighted a significant increase in positive cases since September, showing no signs of decline yet.

Co-occurring Malaria Cases
Beyond dengue, the health department also reported 215,270 malaria cases across Sindh this year, with 3,072 in Karachi between January 1 and October 15. The districts most affected by malaria include Jamshoro, Larkana, Jacobabad, Badin, Mirpurkhas, and Shaheed Benazirabad. However, hospital data from Indus Hospital, SIDHRC, LNH, and JPMC contradicted official figures, indicating over 1,800 malaria cases in Karachi from September 1 to October 16. Dr. Mahmood further observed that malaria appeared at least a month earlier this year than is typical.
Public Health Response and Expert Concerns
While the health department has not addressed queries regarding the data discrepancy, Sindh Health Minister Azra Pechuho urged public participation in preventing mosquito breeding. She stated that the government is implementing comprehensive measures to curb disease spread. Anti-dengue campaigns have been intensified across all divisions, including Karachi, where daily fumigation and spraying operations are underway. Additionally, hospitals have received instructions to provide specialized medical attention and immediate treatment to dengue patients. Health department teams are monitoring suspected and confirmed cases across districts and coordinating with local administrations for preventive and remedial actions.
