Residents of Gulmohar Park in South Delhi are experiencing a troubling rise in cases of waterborne diseases, including typhoid and diarrhoea, amid a drinking water contamination crisis. Dr. Arjun Dang, CEO of Dr Dang Lab, highlights a concerning trend of mixed infections involving various pathogens such as E. coli, Shigella, and Salmonella, complicating diagnosis and treatment. Vulnerable populations, particularly children and the elderly, are at heightened risk due to compromised immune systems. Dr. SC Chatterjee emphasizes the importance of preventive measures, recommending the consumption of boiled or clean water and maintaining hygiene practices. The surge in infections among children has prompted the use of multiplex PCR testing to identify the specific pathogens involved, which can help avoid unnecessary antibiotic use. Experts stress that access to safe drinking water is critical for public health, especially during the summer and monsoon seasons when the risk of contamination increases. Advanced diagnostics are becoming essential for timely intervention and effective public health responses.
