The recent confirmation by the Health Ministry that two elderly women succumbed to West Nile fever at Rabin Medical Center has cast a spotlight on the growing threat of this virus. With 21 cases diagnosed so far, 17 of which required hospitalization, the urgency to address this public health issue has never been greater. Currently, three patients remain on ventilators, fighting for their lives against this potentially deadly virus.
The two women who lost their lives were residents of Petah Tikva and Rosh HaAyin, both over 80 years old. Their tragic deaths underscore the heightened risk that West Nile fever poses to older adults and those with compromised immune systems. At Tel Aviv Sourasky Medical Center and Meir Medical Center, several other patients are also grappling with severe symptoms of the virus, highlighting the widespread impact of this outbreak.
The Health Ministry has long been aware of West Nile fever’s presence in Israel, typically observing cases between June and November. However, this year’s outbreak has started earlier than usual, likely influenced by climate changes that have created more favorable conditions for mosquito breeding and development. The humid weather in central Israel is particularly conducive to the proliferation of mosquitoes, which are the primary carriers of the virus.
West Nile fever is a tricky disease, as about 80% of those infected show no symptoms, making it challenging to detect and control. For the remaining 20%, symptoms can range from mild, flu-like conditions to severe neurological complications such as acute encephalitis or meningitis. The most severe cases can be fatal, particularly among the elderly and immunocompromised individuals.
Since 2011, the majority of diagnosed patients in Israel have been over the age of 65, reinforcing the need for targeted health interventions for this vulnerable population. The Health Ministry has responded by refining its guidelines for medical professionals, stressing the importance of early diagnosis and vigilant monitoring. An epidemiological investigation follows each case, with findings shared with the Environmental Protection Ministry to implement local pest control measures.
Public awareness is also a critical component of the Health Ministry’s strategy. Informing communities about areas where infected mosquitoes have been detected can help residents take preventive measures, such as using insect repellent and eliminating standing water where mosquitoes breed.
The deaths of these two women are a sobering reminder of the dangers posed by West Nile fever. This outbreak serves as a wake-up call for both public health authorities and the general public. It underscores the need for increased vigilance, better diagnostic tools, and more effective preventive measures to protect those most at risk. As climate change continues to alter weather patterns and create more hospitable environments for disease-carrying vectors, the battle against West Nile fever and similar diseases will only intensify.
