Which group of people is at higher risk for severe outcomes from mosquito-borne illnesses?

Elderly individuals and those with weakened immune systems are at higher risk for severe outcomes from mosquito-borne illnesses due to several factors. As people age, their immune systems typically weaken, making it harder for their bodies to fight off infections, including those caused by mosquitoes. Additionally, individuals with compromised immune systems, whether due to chronic illnesses, medications, or other health conditions, have a diminished ability to respond effectively to pathogens. This can lead to more severe symptoms and complications when infected with diseases transmitted by mosquitoes, such as West Nile virus or Zika virus.

Understanding this higher vulnerability among certain groups is crucial for public health awareness and preventive measures, such as vaccination, mosquito control efforts, and community education aimed at reducing exposure, particularly in those populations that are more susceptible to the harmful effects of these illnesses.
