The most common symptons of typhoid include a high fever, stomach pain, headache and constipation or diarrhoea. If the symptons are not treated there is a possibility for the them to become worse and lead to the a higher risk of the disease being fatal.
Travellers travelling to at risk coutries are advised to receive a typhoid vaccination. The vaccination can either be given orally (a course of 3 capsules) or an injection. The oral typhoid vaccination is approximately 80% the effectiveness of the injection and is advised for people who are unable to receive the injection. The typhoid injection is effective for up to 3 years.
