Signs and Symptoms

Infections of the gut cause diarrhoea and sometimes vomiting and fever. Other symptoms typically include stomach cramps and headache. Vomiting usually settles quickly but diarrhoea may last for a week or more. When the cause is bacterial, the diarrhoea may contain blood and mucus.

Illness due to viruses and bacteria usually develops in one to three days after exposure to the organism. Diarrhoea due to parasites usually develops five to fifteen days after exposure to the organism.
