Dengue is the most common mosquito-borne viral disease of humans that in recent years has become a major international public health concern.
Yellow fever is a viral disease, found in tropical regions of Africa and the Americas. It principally affects humans and monkeys, and is transmitted via the bite of Aedes mosquitoes. It can produce devastating outbreaks, which can be prevented and controlled by mass vaccination campaigns.
Information extracted from the Malaria - Topics in International Health CD-ROM published by the Wellcome Trust, and from a Roll Back Malaria information booklet Introduction.
These are areas where the virus is present in monkeys and is a potential risk to humans as defined by the World Health Organisation. Some of these countries demand a yellow fever certificate from travellers as a condition of entry to their country. Many of these, and other countries, will ask you for a certificate if you are entering from an infected country.
Malaria is a serious, sometimes fatal, tropical disease spread by mosquito bites. The World Health Organization estimates 3.3 billion people (half the world’s population) are at risk from malaria, with approximately 250 million cases and nearly one million deaths every year.
Dengue is transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses. It occurs in tropical and sub-tropical areas of the world. Symptoms appear 3—14 days after the infective bite. Dengue fever is a febrile illness that affects infants, young children and adults.
Symptoms range from a mild fever, to incapacitating high fever, with severe headache, pain behind the eyes, muscle and joint pain, and rash. There are no specific antiviral medicines for dengue. It is important to maintain hydration. Use of acetylsalicylic acid (e.g. aspirin) and non steroidal anti-inflammatory drugs (e.g. Ibuprofen) is not recommended.
Dengue haemorrhagic fever (fever, abdominal pain, vomiting, bleeding) is a potentially lethal complication, affecting mainly children. Early clinical diagnosis and careful clinical management by experienced physicians and nurses increase survival of patients.
The best prevention is personal protection against the mosquito. Malaria mosquitoes generally bite after dark, wear long sleeves and trousers in the afternoon and evening; stay in-doors if possible. Use insect repellent on exposed skin.
You are advised to visit your general practice surgery or a travel medicine clinic at least 6 weeks before you travel. However, it is never too late to seek advice.
If you have a medical condition, you are advised to discuss the suitability of the trip before you book.
