Yellow Fever
1 The official WHO list of countries with risk of YFV transmission can be found in Table 3-21. Proof of yellow fever vaccination should be required only if traveling from a country on the WHO list, unless otherwise specified. The following countries, containing only areas with low potential for exposure to YFV, are not on the WHO list: Eritrea, São Tomé and Príncipe, Somalia, Tanzania, Zambia.
2 An elevation of 2,300 m is equivalent to 7,546 ft.

Malaria
3 This risk estimate is based largely on cases occurring in US military personnel who travel for extended periods of time with unique itineraries that likely do not reflect the risk for the average US traveler.
4 Refers to P. falciparum malaria unless otherwise noted.
5 Primaquine can cause hemolytic anemia in people with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Patients must be screened for G6PD deficiency before starting primaquine.

Yellow Fever Maps
1 Yellow fever (YF) vaccination is generally not recommended in areas where there is low potential for YF virus exposure. However, vaccination might be considered for a small subset of travelers to these areas who are at increased risk for exposure to YF virus because of prolonged travel, heavy exposure to mosquitoes, or inability to avoid mosquito bites. Consideration for vaccination of any traveler must take into account the traveler’s risk of being infected with YF virus, country entry requirements, and individual risk factors for serious vaccine-associated adverse events (e.g., age, immune status).
