Question
How does the transmission of the following disease take place?
Amoebiasis
Solution
The disease called amoeba or amoebic dysentery is caused by a protozoan parasite called Entamoeba histolytica found in the large intestine of humans. The symptoms of this disease are constipation, abdominal pain and cramps, stools containing excessive mucus and blood clots, etc. The carriers of this disease are house flies, which carry the parasite from the stools of the infected person to food and food items, thereby contaminating them. Contaminated drinking water and food items are the major sources of infection. To avoid this, rules of hygiene should be followed and food items should be kept covered.
