If you are planning to travel to exotic destinations, such as tropical regions in Africa and Latin America, you may need to get vaccinated against yellow fever. This article helps you with important information about the need for vaccination, risk areas and how to protect yourself during your travels.

Importance of yellow fever vaccination

Vaccination against yellow fever is essential for anyone traveling to endemic areas. It is a highly effective preventative measure against a disease that can be serious, transmitted by infected mosquitoes.

What is yellow fever?

Yellow fever is a viral disease transmitted by the bite of infected mosquitoes, such as Aedes aegypti. Initial symptoms include fever, headaches, nausea, muscle pain, fatigue and jaundice (yellowing of the skin). Although many people recover within a few days, around 10 to 20% of those infected can develop severe forms of the disease that can be lethal.

Why should you get vaccinated?

If you are going to an area where yellow fever is endemic, vaccination is a fundamental preventative measure. There is a safe and very effective vaccine that is recommended for those traveling to risk areas. However, there are specific contraindications to this vaccine, and it is important to get advice beforehand at the traveler's clinic.
