Waterborne Epidemics Affect Multiple Indian Cities
Waterborne disease epidemics are spreading across several parts of India, with significant outbreaks reported in Palwal (Haryana), Kolkata, Gandhinagar, and Indore. The outbreaks have caused numerous illnesses and deaths, highlighting persistent challenges in providing clean water and sanitation.
- In Indore, the contamination was traced to raw sewage leaking from a police outpost's toilet, which lacked a septic tank, into a 30-year-old water pipeline, contaminating the supply for approximately 50,000 residents. Laboratory tests of the municipal water confirmed the presence of a lethal mix of E. coli, Salmonella, and Vibrio cholerae, among other pathogens. - The Gandhinagar typhoid outbreak, which resulted in over 130 cases, was linked to leakages in water and sewage pipelines that were approximately 35 years old. An increase in water pressure is believed to have caused failures at weak points in the aging infrastructure. - In Palwal's Chayansa village, a health emergency was declared after 15 deaths were reported between January 6 and February 11. While at least six deaths were attributed to liver-related complications like Hepatitis B and jaundice, screening of 1,500 residents also found 37 cases of Hepatitis C and one case of HIV, complicating the investigation into the exact source of the outbreak. - A major diarrhea outbreak in Kolkata's New Town affected over 300 residents of a single housing complex. Families reported that their complaints about contaminated water had been ignored by authorities prior to the widespread illness. - Waterborne diseases like acute diarrheal disease, typhoid, and viral hepatitis led to over 10,738 deaths in India in the five years leading up to 2019. Acute diarrheal diseases were responsible for the majority of these fatalities. - A 2023 study estimated that typhoid fever alone caused approximately 4.9 million cases and nearly 8,000 deaths in India during that year. The research also highlighted a significant concern with antimicrobial resistance, finding that over two-thirds of typhoid cases are resistant to fluoroquinolones, a common antibiotic treatment. - The Indian government's Jal Jeevan Mission, launched in 2019, aims to provide safe and adequate drinking water through individual household tap connections to all rural households by 2024. As of March 2025, about 73% of rural households were reported to have tap water connections. - Despite progress in providing tap water access, significant challenges remain, including aging infrastructure, contamination of water sources, and gaps in last-mile delivery, particularly in hilly or tribal regions. A 2024 report from the Union Ministry of Jal Shakti noted that in Gandhinagar, fewer than a third of households receive potable drinking water via tap connections.
