The World Health Organization (WHO) has expressed serious concern over a possible polio outbreak in Gaza following the detection of traces of the virus in wastewater samples. Dr. Ayadil Saparbekov, the WHO’s head in the Palestinian territories, revealed that a risk assessment is underway and health workers are advising Gaza’s 2.3 million residents on protective measures. However, the effectiveness of these measures is compromised by the region’s deteriorating water and sanitation infrastructure.
Polio traces, which were discovered in sewage from two sites in Gaza a month ago, suggest that the virus may be circulating in the area. Although no paralytic cases have been reported yet, the Israeli military has commenced a vaccination campaign for its soldiers and is working with various organizations to deliver vaccines to Palestinians in Gaza. Since the start of the conflict between Israel and Hamas in October, about 300,000 vaccines have been sent to the region.
The WHO and UNICEF are considering a mass vaccination campaign, but logistical challenges, including frequent aid delays and security issues, are hindering these efforts. The Israeli military is collaborating with organizations to facilitate vaccine distribution amidst the ongoing conflict.
Polio, a highly infectious virus spread through contaminated feces or respiratory droplets, can cause paralysis and, in severe cases, death. Immunization rates in Gaza were high before the conflict, with coverage at 99% in 2022. However, this rate fell to 89% last year due to the war’s impact on healthcare infrastructure. The destruction of Gaza’s health system, with only 16 out of 36 hospitals operational, combined with poor water quality and sanitation, has further exacerbated the risk of disease spread.
Dr. Saparbekov highlighted the dire conditions in shelters, where inadequate sanitation facilities are increasing the risk of polio transmission. The Hamas-run health ministry has warned of a “health catastrophe” following the polio detection.
The WHO has stressed the need for a ceasefire to allow an effective response to the health crisis. This call is echoed by eight Israeli public health professors who have urged for urgent action to protect both Palestinian and Israeli infants who are at risk of not completing their vaccinations.
