Zambia has recently confirmed the detection of poliovirus in environmental samples collected in Zambia, specifically in the capital city, Lusaka. Although no confirmed cases of paralytic polio have been reported, the presence of the virus in wastewater signals possible silent transmission within communities, particularly among unvaccinated children.Polio is a highly infectious viral disease that primarily affects children under five years of age. It spreads through contaminated water, poor sanitation, and close person-to-person contact. In severe cases, it can cause irreversible paralysis and even death. While Zambia had previously achieved polio-free status, this recent detection highlights how easily the virus can re-emerge if population immunity declines.Globally, the fight against polio has been led by initiatives supported by the World Health Organization and international partners, resulting in dramatic reductions in cases over the past decades. However, outbreaks continue to occur in areas where immunization coverage is incomplete, reinforcing the need for sustained vaccination efforts and strong surveillance systems.In response, Zambian health authorities have activated emergency response measures, including intensified surveillance and targeted immunization campaigns aimed at protecting all eligible children. These efforts are critical to preventing further spread and safeguarding public health.The recent outbreak serves as an important reminder: polio eradication requires constant vigilance, community participation, and full vaccination coverage. Protecting every child through immunization remains the most effective way to stop the virus and keep Zambia polio-free.
