Waterborne illness outbreaks are triggered by the monsoon.

KARACHI: Doctors have cautioned that an increase in cholera and diarrhea cases has resulted from the mixing of sewage into drinking water lines in certain neighborhoods, as the city continues to experience sporadic monsoon rains.

In an interview with The Express Tribune, doctors blame the inadequate sewage system for the degradation of the drinking water supply and the rise of waterborne diseases in the metropolis.
Data from major government hospitals in Karachi indicate that within the previous few days, there has been a noticeable increase in the number of cases of diarrhea and cholera. The number of diarrhea and cholera cases per day at JPMC has increased from 40–45 to 70–80. Comparably, 20–22 cases per day, up from 4-5 cases per day, have been reported by Civil Hospital.
The chief of Civil Hospital's Accidents and Emergency Department, Dr. Imran Sarwar, attested to the fact that an increase in cases is directly related to sewage contaminating water lines.
The situation has gotten worse since the recent monsoon rains, according to Dr. Irfan Siddiqui, the morning shift supervisor of JPMC's Accidents and Emergency Department. This has made the problem of sewage mingling with water lines worse. Those with compromised immune systems, adults, and children have been disproportionately affected by the rise in incidence. In order to lessen the danger of these waterborne illnesses, medical professionals urge the public to drink only boiling water and steer clear of poor quality food. Additionally, they emphasize how crucial it is to provide children and the elderly with watchful care at this time.
