Almost all Out patient Departments (OPDs) across Delhi hospitals are getting at least 2-3 cases of gastroenteritis and hepatitis A infections daily.
"The situation is usually bad this time of the year but this year particularly several patients are complaining of dirty water supply in their areas," said a doctor from the department of medicine at Aiims.
A person falls sick by drinking polluted water either directly or by use of such water in cooking, washing or for other personal purposes. The microorganisms of these diseases multiply in the body and the infection is excreted with the person's stool or urine. Situation at Delhi government's biggest hospital Lok Nayak is no different.
"Although we haven't seen many typhoid cases this season, diarrhoea, jaundice and gastroenteritis patient load is huge," said a doctor at Lok Nayak, wishing to remain anonymous.
"We are asking patients not to self-medicate. Most cases are that of viral infection, which needs re-hydration treatment besides lots of rest. Only bacterial infections like typhoid need antibiotics," said the doctor.
Private hospitals are also getting their share of cases with symptoms of water-borne infections in equally high number.
"Children less than five years of age are more prone to diarrhoea as they tend to consume water while brushing or bathing," said Dr Rahul Nagpal, head of department of paediatrics at Max Healthcare.
"I see at least three people in a day who complain of diarrhoea and vomiting. Most of them test positive for jaundice," said Dr Suranjit Chatterjee, senior consultant, internal medicine at Indraprastha Apollo hospital.
Doctors at Fortis Hospital at Vasant Kunj are also receiving 2-3 cases of gastro-intestinal infections. Records from a single OPD last week showed five cases of jaundice.
Faridabad, too, has been witnessing a sharp rise in gastroenteritis cases.
