- Mosquito bite
- Mosquitoes that spread dengue fever usually bite during the day, especially in early morning and late afternoon and evening
- During pregnancy, from mother to child
- Organ transplants and blood transfusions from infected donors
- Starts with sudden fever.
- Can be accompanied by severe headache, muscle and joint pain, pain behind the eyes, nausea, vomiting, swollen glands and a rash.
- In some very severe cases, the disease can cause severe stomach pain, difficulty breathing and bleeding (known as “dengue haemorrhagic fever”), and even death.
- Prevention of mosquito bites by placing insect screens on windows and doors and wearing personal protection (apply repellents, wear long sleeved clothes, etc.)
- Community clean-up campaigns to remove rubbish and cover water containers
- Destruction of mosquito breeding sites by removing standing water, fogging, and applying larvicides
- Routine vaccination
- Social mobilization and behaviour change communication
- Any person in the community can get dengue fever; but babies and young children are at higher risk of severe dengue fever
- Dengue fever is important for pregnant women because they can pass the disease to their unborn baby
If an epidemic occurs
- Increase community-based surveillance
- Rapidly detect and refer serious cases to health facilities
- Increase social mobilization and behaviour change communication
- Promote community clean-up campaigns to remove rubbish and cover water containers
- Support mass vaccination campaigns if vaccination is part of country’s dengue control programme and encourage social mobilization to support them
- Promote the prevention of mosquito bites by placing insect screens on windows and doors and wearing personal protection (apply repellents, wear long sleeved clothes, etc.)
- Eliminate mosquito breeding sites by removing standing water, fogging, and applying larvicides
- Encourage young children and people who sleep during the day to sleep under a mosquito net (if windows and doors are not screened)
