Typhoid and cholera are spread in the same way as hepatitis A.
Typhoid produces a persistent high fever with malaise, headaches and abdominal pains, followed by diarrhoea. Vaccination can be by injection or orally, but the oral alternative is less effective, more expensive and only lasts a year, as opposed to three for a shot in the arm.
Cholera appears in epidemics rather than isolated cases - if it's about, you should know. It is characterized by sudden attacks of watery diarrhoea with severe cramps and debilitation. The vaccination is no longer given anywhere as it is ineffective.
