These measures are crucial for limiting the transmission of the bacterium *Vibrio cholerae*, which causes the disease and is typically spread through water or food contaminated with feces [\[1\]](). Oral cholera vaccines can help provide additional protection, especially in areas at risk of outbreaks. It is also essential to be aware of the symptoms of cholera and how to act quickly if they appear. ## The Importance of Clean Water and Sanitation Providing clean drinking water and basic sanitation are among the most important pillars of cholera prevention. Cholera is primarily transmitted by consuming water or food contaminated with the *Vibrio cholerae* bacterium [\[1\]](). Therefore, one must ensure all drinking water sources are safe. This can be achieved by boiling water, using iodine tablets for purification, or relying on bottled water [\[2\]](). Additionally, sanitation infrastructure plays a vital role in preventing the spread of cholera. Areas that lack water treatment and proper sanitation are more susceptible to outbreaks [\[3\]](). One must take care to dispose of human waste safely to prevent contamination of water and food sources. ## Personal Hygiene and Food Safety Good personal hygiene practices, especially handwashing, are essential for preventing cholera. Hands should be washed regularly with soap and water, especially after using the toilet and before preparing or eating food [\[2\]](). This simple habit significantly reduces the risk of bacterial transmission. Regarding food safety, ensure food is cooked thoroughly and served hot. Avoid raw fruits and vegetables that have not been washed or peeled [\[2\]](). It is also advised to avoid food sold by street vendors if you are unsure about the hygiene of its preparation. Storing food safely and avoiding cross-contamination between raw and cooked foods also contributes to prevention. ## The Role of Oral Cholera Vaccines Oral cholera vaccines are available and can provide protection against the disease [\[1\]](). There are three WHO-prequalified oral vaccines: Dukoral®, Euvichol-Plus®, and Euvichol-S® [\[1\]](). These vaccines generally require two doses to provide full protection for adults, although one dose of Euvichol-Plus® or Euvichol-S® can provide short-term protection [\[1\]](). Vaccines are recommended for people traveling to areas experiencing active cholera outbreaks or during mass vaccination campaigns [\[1\]](). Although vaccines are effective, they do not eliminate the need for strict adherence to clean water, sanitation, and personal hygiene practices. ## What to Do if You Suspect Infection If you experience cholera symptoms, such as severe watery diarrhea, vomiting, or leg cramps, it is essential to seek medical attention immediately [\[2\]](). Rapid dehydration can lead to serious complications and can be fatal within hours if left untreated [\[1\]](). Basic treatment involves replacing lost fluids and salts, typically using oral rehydration solution; severe cases may require intravenous fluids and antibiotics [\[1\]]().
