Yellow fever is a viral disease transmitted by mosquitoes in parts of Africa and South America. Vaccination is safe and effective and is a legal requirement for people travelling through infected areas. Avoiding mosquito bites is also recommended to reduce the risk of catching yellow fever or other mosquito-borne diseases.
Symptoms of yellow fever
The first symptoms of yellow fever appear three to six days after exposure to the virus. They include:
- Fever
- Nausea
- Vomiting
- Flushed face
- Constipation
- Stomach ache
- Headache
- Muscle pain
- Restlessness and irritability.
Mild cases of yellow fever end with the above symptoms. In severe cases, there may be a remission from these symptoms for several hours or days. The fever then returns and the patient develops the classic symptoms of jaundice (yellow eyes and skin) and black, ‘coffee-ground’ vomit. This can be followed by coma and death within days.
Yellow fever vaccination
If you are travelling or passing through areas infected with yellow fever, some countries require you to be vaccinated. A record of your immunisation must be entered and validated in your International Certificate of Vaccination or Prophylaxis. While some countries have no entry requirements, others may require an International Certificate of Vaccination for all travellers. It is best to get the vaccination to ensure that you meet the varying entry requirements.
You should find out if the countries you intend to visit have requirements for yellow fever vaccination. Also speak to your doctor at least two months before you travel to arrange vaccinations. You must have the yellow fever vaccine at least 10 days before entering a country that requires you to have it, otherwise you may have to go into quarantine.
Requirements and risks of yellow fever vaccination
Yellow fever vaccine is safe and effective and lasts for 10 years. The vaccine, however, has some strict requirements. It should not be given to people who are:
- Allergic to eggs or neomycin
- Immune-deficient
- Pregnant
- Under nine months of age – it should only be given to younger infants and pregnant women in unavoidable, high-risk circumstances.
Reactions to the vaccine are generally mild, and may include fever, headache and muscle ache, which occur five to 14 days after immunisation. Serious side effects are rare, but any problems should be immediately referred to a doctor.
Avoid mosquito bites
Whether or not you need to be vaccinated, it is always a good idea when travelling to protect against mosquito bites and so reduce the risk of catching a mosquito-borne illness. Some tips include:
- Wearing mosquito repellent that contains at least 30 per cent DEET
- Applying repellent, such as permethrin, to your clothes and bedding
- Wearing socks, long pants, and long-sleeved shirts when outdoors
- Using a bed net
- Staying in air-conditioned, screened accommodation.
