Pakistan’s Combating Wild Poliovirus (WPV): Efforts and Lessons Learned

Dr. Bahadar Shah — Mon, 30 Jun 2025 00:00:00 +0000

Pakistan stands at a critical juncture in the history of public health. As one of only two remaining countries endemic for wild poliovirus (WPV), alongside Afghanistan, the nation carries a significant burden—and an even greater responsibility—in the global quest for eradication. The fight against polio in Pakistan is a complex tapestry woven with threads of remarkable resilience, innovative strategies, hard-won successes, and persistent, daunting challenges. From a public health perspective, understanding this landscape is paramount, not just for Pakistan but for the health security of the world. Despite decades of effort, WPV transmission stubbornly lingers, primarily in specific high-risk zones of Khyber Pakhtunkhwa (KP) and parts of Balochistan and Sindh. The year 2023 saw only 6 reported WPV1 cases – a significant reduction from peaks exceeding 300 annually, demonstrating progress. However, the continued detection of the virus in environmental samples from major cities like Karachi, Peshawar, Quetta, and Bannu underscores the silent circulation and the ever-present risk of resurgence. Key reservoirs remain in areas characterized by insecurity, population mobility, low routine immunization coverage, and persistent community refusals. Pakistan has come too far and invested too much to falter now. The recent low case numbers are encouraging but fragile. The virus exploits any gap with ruthless efficiency. The strategies are proven; the successes demonstrate what is possible. The end of polio in Pakistan is within sight. Achieving it will be one of public health's greatest triumphs, a testament to human perseverance and collaboration. It is not just an option; it is an ethical and practical imperative for the health of Pakistan's children and the world. The time for the final, decisive push is now.

Protozoa are unicellular eukaryotic organisms that exist in biomes, both land and water. Out of about 200,000 currently known species of protists, over 199,000 (or about 99 %) are autotrophs or heterotrophs that occupy free-living niches, while the rest, only 1%, are obligate symbionts that live inside or on a definite host organism. The research aimed to conduct an empirical study of the prevalence of free-living protozoans from the River Indus, Sindh, Pakistan. In the case of a research study on the water quality of rivers in Hyderabad, Sindh, Pakistan, the polypropylene water bottles and plastic zip-lock bags were used to fill the samples of river water in the River Indus. To ensure the understanding of measurements of dissolved oxygen, free CO₂, phosphate, nitrate, and biological oxygen demand, water samples were put through several standard analytical processes. Results indicate that Amoeba proteus exists at high levels in every season, particularly in winter and summer. The Paramecium was most abundant during the summer. In contrast, the number of Tintinnopsis became moderate all year, but they increased a bit during the monsoon. The winter and summer months saw the lowest numbers for Oxytricha, possibly because it isn’t as adaptable to its surroundings. This virus remains stable most of the year, except for a small increase in the summer. These results highlight the usefulness of protozoan surveillance as a bioindicator in measuring the level of water quality, as well as give credence to the notion that there should always be periodic surveillance and analysis in determining policies guiding the preservation efforts.

Rare diseases, which affect less than 1 in 2,000 people, are difficult to diagnose and treat due to their complex pathophysiology and genetic variation. Recent advances in artificial intelligence (AI) and multi-omics technologies, including proteomics, metabolomics, and genomics, may help us better understand the molecular mechanisms underlying these diseases. This study was aimed to explore how AI integrates multi-omics data to identify biomarkers, forecast treatment targets for rare diseases, and uncover disease-causing pathways. It highlights how AI may help with data complexity, enable personalized care, and enhance predictive modeling. Despite progress, problems like consistency, model interpretability, and data scarcity persist. By integrating recent research, this paper proposes future directions to accelerate clinical translation and highlights AI-driven multi-omics as a groundbreaking approach to understanding the mechanisms underlying uncommon diseases.

Global Strategies for Combating Antimicrobial Resistance through the One Health Approach: A Mini Review

Sun, 27 Jul 2025 00:00:00 +0000

The introduction of antibiotics revolutionized medicine by significantly reducing the burden of bacterial infections. However, antimicrobial resistance (AMR) has emerged as a major global health and economic challenge. AMR arises primarily from the misuse and overuse of antimicrobials in human health, agriculture, and animal husbandry. It leads to treatment failures, prolonged illnesses, and increased mortality. The One Health approach, which integrates human, animal, and environmental health, provides a comprehensive framework for addressing AMR. The extensive use of critically important antimicrobials such as fluoroquinolones, cephalosporins, colistin, tetracyclines, and macrolides in food-producing animals is a key driver of resistance. Prudent antimicrobial use, infection prevention, and enhanced hygiene are vital in human healthcare. In animal agriculture, reducing prophylactic and growth-promoting antimicrobial use is essential. Surveillance systems help track resistance trends across sectors. Internationally, the WHO-led Global Action Plan (GAP), supported by the FAO and WOAH, emphasizes antimicrobial stewardship, resistance surveillance, and policy harmonization. At the national level, countries implement National Action Plans (NAPs) that promote public awareness, antimicrobial regulation, and research into alternatives. Tackling AMR requires a coordinated multisectoral response. The One Health approach embedded in both national and global strategies is crucial for preserving the efficacy of antimicrobials and safeguarding health across species and environments.

Genomic Analysis of Cephalosporin Resistance in Salmonella: A One Health Perspective on the Transmission of Resistance Genes between Animals, Humans, and the Environment in Punjab, Pakistan

Sun, 27 Jul 2025 00:00:00 +0000

Antimicrobial resistance (AMR) in Salmonella, particularly to third-generation cephalosporins, is a rising public health threat, especially in developing regions with dense human-animal-environment interactions. This study evaluates cephalosporin resistance in Salmonella through a One Health lens in Punjab, Pakistan, using whole-genome sequencing (WGS) to uncover resistance mechanisms and transmission dynamics. Phenotypic resistance was determined through antimicrobial susceptibility testing, while genotypic resistance was characterized using WGS. Phylogenetic analysis and multilocus sequence typing (MLST) were used to map potential transmission routes. Salmonella was isolated from 33.4% of samples, with the highest prevalence in poultry (42%). Cephalosporin resistance was phenotypically observed in 52.7% of isolates, with 72.7% being ESBL-producers. WGS revealed the presence of CTX-M-15 (58%), TEM-1 (29.5%), and CMY-2 (20.5%) among resistant strains. Significant SNP-based phylogenetic relatedness was observed between human, animal, and environmental isolates, indicating active cross-sector transmission. Notably, poultry and wastewater sources were major transmission hubs. This study presents robust genomic evidence that cephalosporin-resistant Salmonella is circulating across animal, human, and environmental sectors in Punjab, Pakistan, with poultry acting as a key reservoir. The detection of widespread resistance genes such as CTX-M-15, TEM-1, and CMY-2, along with evidence of mobile genetic elements (e.g., IncFII, IncI2 plasmids), underscores the critical role of horizontal gene transfer in resistance propagation. The strong genetic relatedness between isolates from live bird markets, hospitals, and wastewater suggests ongoing transmission across the One Health spectrum.
