the national <a href=\"https:\/\/www.health.gov.za\/\" type=\"link\" id=\"https:\/\/www.health.gov.za\/\">Department of Health<\/a> says there is no need for panic as no human cases have been identified.<\/p>\n\n\n\n<p>The National Institute for Communicable Diseases (NICD) informed the department that the strains, identified as VDPV3 and nOPV2-L, were detected during routine environmental and wastewater surveillance in the Western Cape.<\/p>\n\n\n\n<p>The department said in a statement, the testing forms part of proactive disease monitoring aimed at detecting emerging outbreaks and viral variants before clinical cases appear.<\/p>\n\n\n\n<p>Officials stressed that the detections are classified as \u201cvaccine events\u201d because the viruses were not found in any person.<\/p>\n\n\n\n<p>\u201cNo outbreak has been declared and no additional vaccination campaign is required,\u201d read the statement.<\/p>\n\n\n\n<p>Polio is a vaccine-preventable disease, and South Africa was officially declared polio-free by the World Health Organization\u2019s African Regional Certification Commission in September 2019.<\/p>\n\n\n\n<p>According to the department, the viruses detected are likely linked to imported cases involving people vaccinated with different vaccines from those used in South Africa.<\/p>\n\n\n\n<p>The department said it is working with the NICD and has since strengthened surveillance measures and increased the frequency of wastewater sampling as part of ongoing monitoring and outbreak preparedness.<\/p>\n\n\n\n<p>It said the detections do not translate into an outbreak and reassured the public that there is no need for panic.<\/p>\n\n\n\n<p>However, residents are encouraged to remain vigilant and report any suspected symptoms to healthcare providers.<\/p>\n\n\n\n<p>Symptoms associated with polio can include progressive muscle or joint weakness and pain, fatigue, muscle wasting, breathing or swallowing difficulties, and sleep-related breathing disorders, although these symptoms may also be linked to other medical conditions.<\/p>\n\n\n\n<p><strong>ALSO READ<\/strong>: <a
