Step-by-step explanation:
Amoebiasis, also known as amoebic dysentery, is most commonly contracted through the ingestion of water or food contaminated with the parasite Entamoeba histolytica. The main route of transmission is through the consumption of fecally contaminated food or water. The infection occurs when a person ingests the cyst form of the parasite, which is found in contaminated food or water sources.
Some common sources of contamination include:
1. Contaminated water: Drinking untreated or improperly treated water from contaminated sources, such as rivers, lakes, or wells, can introduce the amoeba into the body.
2. Contaminated food: Consuming raw or undercooked food that has been contaminated with the cysts of Entamoeba histolytica can lead to infection. This can include fruits, vegetables, or salads washed with contaminated water, as well as raw or undercooked meat or seafood.
3. Poor hygiene practices: Lack of proper hygiene, such as inadequate handwashing after using the toilet, can contribute to the spread of the parasite. This can lead to contamination of surfaces, objects, or food that may be touched or consumed by others.
4. Person-to-person transmission: Direct contact with an infected individual who has poor hygiene practices can also facilitate the transmission of the parasite. This can occur through activities such as sexual contact or the sharing of personal items contaminated with fecal matter.
It is important to note that not all individuals infected with Entamoeba histolytica develop symptoms. However, for those who do, symptoms can include diarrhea (which may contain blood or mucus), abdominal pain, cramping, and fever. Prompt diagnosis and treatment are crucial to prevent complications and the spread of the infection to others.
