Patients usually have fever that rises over 2-3 days. They have toxic look, gaseous distension of abdomen and a coated tongue. In few patients, mild jaundice and swelling over the liver may be present.

Other is an injectable vaccine that needs to be given intramuscular as one shot. Both vaccines give protection for 2-3 years following which repeat shot may be required to ensure continued protection. Injectable vaccine can be given after 2 years of age and oral vaccine capsule can be given after 6-8 years of age.
Drinking boiled water with regular washing of raw fruits and vegetables before consumption ensures reasonable good prevention.
