Do you know International regulations require proof of yellow fever vaccination for travel? Yellow fever can be prevented by vaccination.
Yellow fever is an acute systemic illness- a hemorrhagic fever – caused by the Flavivirus. Acute means it comes on (onset) rapidly, while systemic means it affects the whole body. In severe cases yellow fever causes a high fever, bleeding into the skin and the death of cells in the liver and kidney. Liver damage results in severe jaundice – yellowing of the skin; hence the name “yellow fever”.
Yellow fever can be prevented by vaccination. Travelers should also take precautions against mosquito bites when in areas with yellow fever transmission. Travelers should get vaccinated for yellow fever before visiting areas where yellow fever is found. If you continue to live or travel in yellow fever-endemic areas, you should receive a booster dose of yellow fever vaccine after 10 years.
In the United States, the vaccine is given only at designated yellow fever vaccination centers. International regulations require proof of yellow fever vaccination for travel to and from certain countries. People who get vaccinated should be given an International Certificate of Vaccination. Also note that the vaccine is to be given 10 days before travel to an endemic area.
If you continue to live or travel in yellow fever-endemic areas, you should receive a booster dose of yellow fever vaccine after 10 years.
After receiving the vaccine, you should receive an International Certificate of Vaccination (yellow card) that has been validated by the vaccination center. This Certificate becomes valid 10 days after vaccination and lasts for 10 years. You will need this card as proof of vaccination to enter certain countries.
