• Symptoms of Dengue:
  • Common symptoms include high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding.
  • Severe cases can lead to Dengue Hemorrhagic Fever or Dengue Shock Syndrome, which can be fatal.
• Prevention of Dengue:
  • Preventive measures include the elimination of mosquito breeding sites, using mosquito repellents, and wearing protective clothing.
  • Community-level interventions like fumigation and awareness campaigns are crucial in controlling outbreaks.
• Global Impact:
  • Dengue is a major public health concern in tropical and subtropical regions, affecting millions annually.
  • According to the World Health Organization (WHO), the incidence of Dengue has grown significantly in recent decades.
