During water analysis in a hostel, amoebic cysts were seen. The best step to manage it is –
**Core Concept**
The presence of amoebic cysts in water indicates a potential outbreak of amoebiasis, a parasitic infection caused by Entamoeba histolytica. Proper management requires identifying the source of contamination and taking measures to prevent further spread.
**Why the Correct Answer is Right**
The most effective step in managing an amoebic outbreak is to **disinfect the water supply**. This involves treating the water with chlorine or ozone to kill the cysts, thereby preventing further transmission to individuals who may consume the contaminated water. Disinfection is crucial because it directly targets the pathogen, reducing the risk of infection.
**Why Each Wrong Option is Incorrect**
**Option A:** Closing the hostel would be an extreme measure and may not be feasible or necessary, especially if the outbreak is contained and the water supply is treated.
**Option B:** Treating individual patients with antiparasitic medication is not the best initial step, as it may not address the source of the contamination and could lead to further spread of the infection.
**Option C:** Testing the water for other pathogens is not directly relevant to managing an amoebic outbreak, although it may be useful in identifying other potential health risks.
**Clinical Pearl / High-Yield Fact**
When dealing with waterborne outbreaks, always prioritize disinfection of the water supply as the primary step in management.
**Correct Answer: C. Disinfect the water supply**
