During water analysis in a hostel, amoebic cysts were seen. The best step to manage it is –
"Amoebic infection is spread by ingestion of food or water contaminated with cysts. since an asymptomatic carrier may excrete upto 15 million cysts/day. Prevention of infection requires adequate sanitation and eradication of cyst carriage. In high risk areas infection can be minimized by avoidance of unpeeled fruits and the use of Bottled water.
Because cysts are resistant to readily attainable levels of chlorine, disinfection by iodination (Tetraglycine hyperiodide) is recommended." - Harrison
