You may be at risk of the disease if you travel to an area where mosquitoes continue to carry the yellow fever virus. These areas include sub-Saharan Africa and tropical South America.
Even if there aren't current reports of infected humans in these areas, it doesn't mean you're risk-free. It's possible that local populations have been vaccinated and are protected from the disease, or that cases of yellow fever just haven't been detected and officially reported.
If you're planning on traveling to these areas, you can protect yourself by getting a yellow fever vaccine at least several weeks before traveling.
Anyone can be infected with the yellow fever virus, but older adults are at greater risk of getting seriously ill.
