Explanation / Answer
1. Since the diarrhea existed for more than 2 weeks, it can be a case of PERSISTANT/ CHRONIC DIARRHEA. Microbial as well as other reasons could the cause of this condition. Still biological causative agents could be parasites and overgrowth of bacteria in small intestine. More specific disease could be "Giardiasis" and causative agent is Giardia [anaerobic and a protozaon].
2. He became infected due to contact with contaminated water / food/ soil. Also drinking water contaminated with feces can be the reason.
The symptoms are seen two days after the person is infected.Indications include diarrhea and gas, along with stomach cramps. This may be lead to dehydration and excessive loss of nutritients from the body which may need prompt medical treatment. The typical and slight infection can be treated without medications. Symptoms are visible for two to six weeks, but can become more severe.
3. Virulence factors are the cysts which are consumed orally.
Intake of water and drugs like tinidazole or auranofin can be used.
5. Since doctors are not able to detect the causative organism in the intial days of infection. This leads to making the condition quite critical. Death may occur but this is rare and mainly due to excessive loss of water from the body.
