The World Health Organization (WHO) has issued a grave warning regarding Ukraine's health system as it faces its third winter of war, anticipating it to be the most challenging yet. Dr. Hans Kluge, WHO's regional director for Europe, highlighted the severe impact of ongoing Russian airstrikes on Ukraine's energy and healthcare infrastructure, which threatens the storage and distribution of vaccines and could lead to increased preventable diseases. Since the invasion began in February 2022, nearly 2,000 attacks on healthcare facilities have been documented, exacerbating vulnerabilities as temperatures drop. The WHO also raised concerns about possible water contamination and rising antimicrobial resistance due to antibiotic misuse. In response, the organization plans to install heating units in hospitals and deploy backup power solutions to mitigate the crisis. The urgency of these measures is underscored by the recent deaths of Red Cross staff in a Russian artillery strike, marking the ongoing peril faced by humanitarian efforts in the region.
