Kohima, April 12: A recent scientific study conducted in Nagaland has raised concerns over the presence of venomous aquatic insects, with experts warning that similar species could also exist in neighbouring Assam, posing a potential but largely overlooked public health risk.
The research, led by Karthik Sunagar and his team, was published on March 26 and focused on three species of water-dwelling insects found in a pond in Dimapur. The study revealed that the venom of these insects contains proteins comparable to those found in viper snake venom, enabling them to immobilise prey almost instantly.
According to the findings, these insects use ultra-fine, needle-like appendages—thinner than a syringe—to inject venom. They are capable of both swimming and flying, and are typically found concealed beneath mud or debris in stagnant water bodies.
Experts noted that while these insects generally avoid human contact, accidental encounters may occur during activities such as fishing or wading in ponds. Surajit Giri, associated with rural healthcare initiatives in Assam, said such bites can be extremely painful and may cause severe swelling, with rare cases potentially leading to serious complications.
Dr Giri further explained that the venom could, in certain instances, interfere with blood clotting, producing effects similar to viper bites and possibly resulting in prolonged bleeding or internal haemorrhage. He referred to a suspected case in Assam where an elderly man reportedly died after experiencing intense pain and stroke-like symptoms, which may have been triggered by venom-induced bleeding in the brain.
Medical experts have cautioned that such incidents could often be misidentified as snakebites due to the sudden onset of symptoms and the absence of visible bite marks. They have called for increased awareness, proper documentation, and further scientific investigation into unexplained injuries or deaths linked to water bodies.
Authorities and healthcare professionals have urged the public to remain vigilant and report any unusual insect sightings or unexplained water-related injuries, stressing the importance of community participation in identifying and addressing this emerging concern.
The findings highlight the need for continued research and preventive measures to better understand and mitigate what could become a significant environmental and public health issue in the region.
