More Information
Dengue fever is prevalent in tropical and subtropical regions. It is transmitted by Aedes mosquitoes, particularly Aedes aegypti. Effective raising of public awareness and mosquito control are critical in managing outbreaks.
Tips
Not recognizing the biphasic nature of the fever (saddle-back fever) and missing the critical early diagnostic signs can delay treatment.
