Persistence of Vibrio cholerae in inter epidemic period--preliminary observations on analysis of water.
Out of the 61 water samples collected from hand pumps and wells from cholera endemic areas of Varanasi City, Vibrio cholerae non 01 was detected in only one sample. However, seven (18.9 per cent) samples out of 37 samples of river water were positive for V. cholerae non 01. None of the samples showed Vibrio cholerae. These observations indicate transmission and dilution of Vibrio cholerae bacillus in environment.
