The U.S. Centers for Disease Control and Prevention (CDC) has issued a Level 2 Travel Health Notice for parts of South America, including specific areas in Peru, due to an increase in yellow fever cases. This notice advises travelers to take enhanced precautions.
"According to the CDC, Machu Picchu is now an area where Yellow Fever vaccination is recommended for travelers," states the alert. Although the peak of Machu Picchu itself is not a risk zone, visitors often pass through affected regions on their way there. The CDC recommends that travelers to these newly identified areas receive vaccinations against yellow fever.
Yellow fever is transmitted through mosquito bites. The most effective prevention methods include avoiding mosquito bites and receiving the yellow fever vaccine when traveling to regions with known transmission risks. "There is no specific treatment or cure for yellow fever," emphasizes the CDC.
Symptoms of yellow fever initially manifest as fever, chills, severe headache, back pain, body aches, nausea, vomiting, fatigue, and weakness. More severe symptoms can include high fever, jaundice (yellowing of skin or eyes), bleeding, shock, and organ failure. Individuals suspecting they have contracted yellow fever should seek medical attention promptly.
Travelers are advised to get vaccinated at least ten days before visiting areas at risk for transmission. Pregnant individuals should consult healthcare providers regarding potential risks associated with travel plans.
The U.S. Embassy in Lima cannot provide or cover medical expenses but maintains a list of local medical providers on its website: https://pe.usembassy.gov/medical-assistance/.
