Significantly higher (p<0.05) infection was observed in monsoon (98.88%) as compared to winter (74.17%), spring (78.88%) and summer (82.72%) season. Significantly higher (p<0.05) infection (100%) was observed during month of August and September while lowest infection was observed during month of November (56.67%).
