What is typhoid fever?
Typhus abdominalis, or typhoid fever or typhoid for short, is caused by a specific subgroup of Salmonella (Salmonella enterica ssp. enterica Serovar Typhi). This is not the normal salmonella disease common in Europe (Salmonella enterica ssp. enterica Serovar Enteritidis). The disease is transmitted through contaminated food or water. Symptoms include a high fever, headache, dry cough, slow pulse, abdominal pain, and there may be a pale, small-spotted rash. Diarrhea and constipation may alternate. The disease can be treated with antibiotics, but in rare cases can be fatal.
