Typhoid Fever kills...news today

1986 I have seen a ward occupied by 28 Typhoid patients. All 28 of them suffered high fever and other complications. Almost all of them contact a common dirty water source adn use it for washing plates, spoons, cups. They boiled their drinking water but not the water used for bath, face washing, an other washing purposes....so where is the source ?of serious Typhoid....

How can you avoid typhoid fever? Two basic actions can protect you from typhoid fever: 1. Avoid risky foods and drinks. 2. Get vaccinated against typhoid fever. It may surprise you, but watching what you eat and drink when you travel is as important as being vaccinated.

"Boil it, cook it, peel it, or forget it"
If you drink water, buy it bottled or bring it to a rolling boil for 1 minute before you drink it. Bottled carbonated water is safer than uncarbonated water.
Ask for drinks without ice unless the ice is made from bottled or boiled water. Avoid popsicles and flavored ices that may have been made with contaminated water.
Eat foods that have been thoroughly cooked and that are still hot and steaming.
Avoid raw vegetables and fruits that cannot be peeled. Vegetables like lettuce are easily contaminated and are very hard to wash well.
When you eat raw fruit or vegetables that can be peeled, peel them yourself. (Wash your hands with soap first.) Do not eat the peelings.
Avoid foods and beverages from street vendors. It is difficult for food to be kept clean on the street, and many travelers get sick from food bought from street vendors.
