Israel Grapples with Mosquito Illnesses: West Nile and Dengue Fever

Israel is facing a surge in mosquito-borne illnesses, with recent reports highlighting the spread of both West Nile virus and dengue fever. The Health Ministry has confirmed seven new cases of dengue fever in Sharm el-Sheikh and at least 100 cases of West Nile virus in central Israel, marking a troubling trend in the region.

West Nile Virus Outbreak

The West Nile virus has led to the hospitalization of numerous patients across central Israel, with Meir Medical Center in Kfar Saba treating 25 individuals, two of whom are in serious condition. Several patients are in critical condition at Sheba Medical Center, with three on ventilators. The Rabin Medical Center-Beilinson Campus in Petah Tikva reports five deaths attributed to the virus.

West Nile virus is typically transmitted from birds to humans through mosquito bites. Most cases are mild, presenting with flu-like symptoms, but severe cases can lead to neurological complications such as meningitis and encephalitis. Patients with chronic illnesses, weakened immune systems, infants, and the elderly are at higher risk for severe outcomes.

Dengue Fever on the Horizon

Dengue fever, another mosquito-borne disease, is emerging as a new threat. The Health Ministry has reported seven cases of dengue fever in travelers returning from Sharm el-Sheikh. According to Prof. Eli Schwartz from Sheba Medical Center, the Asian tiger mosquito, which transmits dengue fever, is already present in Israel. Climate change is likely to exacerbate the spread of this virus.

Dengue fever is prevalent in Southeast Asia, Latin America, and Africa, and its presence in Israel is a matter of when, not if, according to the experts. Dengue fever symptoms include high fever, severe headaches, muscle and joint pain, and a rash. Severe cases can result in bleeding, organ failure, and death.

Mitigation and Prevention Efforts

Israeli health authorities are intensifying efforts to combat the spread of these diseases. The Environmental Protection Ministry is focusing on mosquito control, particularly in areas with standing water where mosquitoes breed. Public awareness campaigns are urging residents to use mosquito repellents and take precautions to avoid bites.

In light of the dengue fever threat, Israel has introduced the Q-dangue vaccine, available in travelers’ clinics. This vaccine is recommended for those traveling to high-risk areas or those who have previously contracted dengue fever.

Prolonged fever, severe headaches, rapid breathing, and decreased consciousness are warning signs that require urgent care.
