Typhoid fever is caused by the bacteria Salmonella typhi.
Typhoid is caught by consuming food or drink that has been handled by someone shedding the bacteria, or if sewage contaminated with S. typhi gets into water used for drinking or washing food.
Hepatitis A is an infection of the liver caused by the hepatitis A virus.
The hepatitis A virus is found in the faeces of infected people. It's spread because of poor personal hygiene, such as when people don't wash their hands after using the toilet.
The most common causes of infection are contaminated food or water and person-to-person contact.Food prepared or washed with contaminated water can also easily transmit the infection. Fruits, salads, raw vegetables and any uncooked foods are considered to be high risk, as are ice, iced drinks and ice cream.
Food that comes into contact with contaminated seawater, for example, shellfish, can also transmit the infection.
