The growth of pneumonic plague was first diagnosed in the city of Surat, Gujarat on  22^nd September 1994.  The reasons for the outbreak of plague at Surat was attributed to the unhealthy sewerage conditions. Two other natural calamities had occurred in the city before the outbreak of plague that contributed in bringing the flees and the rats in contact with the human community. A combination of heavy monsoon rain and clogged sewers led to massive flooding which resulted in unhygienic conditions and a number of uncleared animal carcasses. The problem of sanitation was also a reason considered for the 1994 outbreak of the disease in the city of Surat.
