As the COVID-19 situation around the world changes, CDC is monitoring COVID-19 risk in each country and making travel recommendations. If you are considering international travel, see CDC’s COVID-19 Travel Recommendations by Destination.

Key points

  • There is an outbreak of cholera in Cameroon's Centre, Littoral, South, Southwest, and North regions.
  • To prevent cholera, travelers should follow safe food and water guidelines, and wash their hands
  • Cholera in travelers is extremely rare but can occur, e.g., among humanitarian aid workers in outbreak settings where there may be limited access to safe food and water.
  • Vaccination against cholera is not routinely recommended because most travelers do not visit areas of active transmission. Travelers (including children) planning to visit regions with active cholera transmission should discuss getting vaccinated with their clinicians before travel.
  • Travelers should seek medical care immediately if they develop severe diarrhea (e.g., persistent and large amounts of watery diarrhea).

What is cholera?

Cholera is an acute diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae. Cholera is spread through contaminated food or water.

It usually takes 2-3 days for symptoms to appear after ingesting cholera bacteria, ranging from a few hours to 5 days.

Cholera can cause large amounts of watery diarrhea (described as a rice-water stool), nausea, and vomiting. Rapid loss of body fluids can lead to dehydration, shock, and even death..
