Dr. GEORGE ROMBO Cholera This is an infection of the small intestine caused by bacterium vibrio cholera. Transmission is mostly from the fecal contamination of food and water that is caused by poor sanitation Susceptibility About 100 million bacteria must typically be ingested to cause cholera in a normal healthy adult. Children are also more susceptible with 2- 4 year old having the highest rates of infection Individual susceptibility to cholera is also affected by their blood type with
