Dengue Cases in Pakistan Surge Over 3,000% in a Decade, Estimated 3.28 Million Infections in 2022

New Delhi, November 1 (Daily Kiran) : A recent study has revealed a staggering increase in dengue infections in Pakistan, with cases rising over 3,000% in the last decade. The research, led by Aga Khan University, estimates that the number of dengue infections soared from approximately 100,000 in 2012 to around 3.28 million in 2022.

Published in the esteemed journal PLOS One, the study indicates that the actual number of dengue cases in Pakistan far exceeds those regularly reported. Researchers found that the current disease surveillance system captures only a fraction of the true infection rate.

Using statistical modeling and laboratory data, the researchers assessed the spread of dengue, a mosquito-borne illness that is rapidly proliferating across the country. The most significant increase in infections was observed among adults aged 15 to 49.

These findings challenge the common belief that dengue is primarily a seasonal illness that peaks after the monsoon. The researchers assert that dengue has now become a year-round threat in Pakistan.

The Sindh province was identified as the most affected area, with an estimated 2.63 million cases reported in 2022. Within the province, Karachi East recorded the highest infection rates. The growing prevalence of dengue in densely populated urban areas poses a substantial public health challenge.

Several factors contributing to the rise in dengue infections were identified in the study, including rapid urbanization, poor drainage systems, stagnant water, and the impact of severe flooding. According to the researchers, these conditions create a conducive environment for the breeding of dengue-carrying mosquitoes, leading to an accelerated spread of the disease. Dr. Jameen Naseem, the lead author of the study, emphasized that dengue in Pakistan is no longer confined to short seasonal outbreaks; it has become a year-round health risk.

The study also highlighted that Pakistan’s current surveillance system fails to accurately assess the true burden of the disease. This shortcoming could hinder effective prevention measures and public health initiatives. The researchers recommended significant reforms to the country’s disease surveillance system, improvements in municipal sanitation and drainage, and the expansion of testing facilities. To tackle the escalating threat of dengue and mitigate the impact of future outbreaks, robust surveillance, better testing capabilities, and effective preventive measures are essential.
