The city of [[Kolkata]], [[India]], in the state of [[West Bengal]] in the [[Ganges delta]], has been described as the "homeland of cholera", with regular outbreaks and pronounced seasonality. In India, where the disease is [[Endemism|endemic]], cholera outbreaks occur every year between [[dry season]]s and [[Wet season|rainy seasons]]. India is also characterized by high population density, unsafe drinking water, open drains, and poor sanitation, which provide an optimal niche for survival, sustenance, and transmission of ''Vibrio cholerae''.<ref>{{cite journal|vauthors=Mandal S|date=July 2011|title=Cholera epidemic in and around Kolkata, India: endemicity and management|journal=Oman Medical Journal|volume=26|issue=4|pages=288–9|doi=10.5001/omj.2011.71|pmc=3191718|pmid=22043439}}</ref>
