Longer Mosquito Season Increases Disease Risk

In a proactive effort to combat mosquito-borne diseases, vector ecologist Zurina Yusoff employs a bulky pellet sprayer to eliminate mosquito eggs, while her colleague Hamiltan Simean sets overnight traps for adult mosquitoes. These public health teams are particularly active during the cooler months, focusing on counting hibernating mosquitoes in dark, damp environments. The urgency of their work is underscored by recent warnings from U.S. health officials regarding a surge in dengue fever cases, which have reached international record levels this year. The West Nile virus remains a significant concern, with symptoms that can severely impact those infected. Carol Wallach, a West Nile virus survivor, recounted her harrowing experience after contracting the disease in the summer of 2022. Wallach described a night of passing out in urgent care, followed by hospitalization due to a combination of fever, rash, severe nerve pain, and difficulty walking. While many West Nile virus infections are asymptomatic, the Centers for Disease Control and Prevention (CDC) reports that approximately 20% of those infected will exhibit symptoms, including headaches, body aches, joint pains, and vomiting. Although most individuals recover completely, some may experience lingering fatigue and weakness for weeks or even months. Wallach's experience highlights the seriousness of mosquito-borne illnesses, prompting her to adopt a more vigilant approach to using insect repellent. Her story serves as a reminder of the ongoing public health challenges posed by these diseases.
