Prevention of Typhoid Fever
To prevent the disease, the following hygiene and dietary measures are recommended:
Washing hands before meals.
Drinking bottled water, and also using it for brushing your teeth.
Peeling fruit with clean hands.
Avoiding raw, marinated or smoked foods.
Not consuming ice in drinks, artisanal dairy products or fresh fruit juices.
Vaccines
There are two types of vaccines against Salmonella typhi which reduce the probability of catching the disease by up to approximately 80%. One of them is a live attenuated vaccine that is administered orally, and the other is an inactivated vaccine injection.
They are recommended for travellers going to endemic or risk zones. It is important to remember that the protection generated by the vaccine does not last in the long term, which means that booster vaccinations are needed every three years if there is continued exposure to the disease.
