Concept Explanation
 

Amoebic Dysentery

Most of Australia is supplied with fresh, clean water, and sewage is treated effectively. This protects us from many diseases found in other parts of the world. You might come into contact with these diseases if you travel overseas, or if some disaster at home damages the sewage system or contaminates the drinking water. One disease spread through contaminated water is amoebic dysentery. This disease causes 50,000-10,00,000 deaths per year worldwide.

Amoebic dysentery is caused by a unicellular (single-celled) organism that is most common in tropical areas. People become infected by swallowing a cyst containing the parasite in contaminated food or water. The cyst is one stage in the cycle of the parasite.

People who contract the disease can remain infectious for years, so it is best to prevent infection when travelling in areas where amoebic dysentery occurs - only drink boiled water or sealed, bottled water, don't have ice in your drinks and don't eat fruit or vegetables that may have been rinsed in tap water and not cooked.
