Researchers in Himachal Pradesh recorded two deaths and two survivors from the Central Asian cobra (Naja oxiana), marking India's fatalities from venomous snake.

Researchers have documented the first confirmed human deaths caused by the Caspian cobra in India, recording two fatalities and two survivals in Himachal Pradesh's Chamba district.

The bites involved the Central Asian cobra, scientifically classified as Naja oxiana. The documented cases mark the first time medical records in India have verified human fatalities attributed specifically to this venomous species.

A newly published medical case report detailed four distinct snakebite incidents within the northern mountainous district. Two victims died following envenomation, while two others survived after receiving treatment.

Documented incidents in Chamba district

Chamba district, located in the high-altitude region of Himachal Pradesh, forms part of the natural geographical range for Naja oxiana. The species is recognized by herpetologists as one of the most venomous cobra variants in Central and South Asia.

While the cobra species is known to inhabit northern mountainous regions of the Indian subcontinent, formal medical documentation of fatal human encounters had not previously entered national public health records.

Public health implications

The case report outlines the clinical challenges in treating bites from rare cobra species in remote regions. The survival of two individuals demonstrates the importance of immediate medical response and antivenom administration in high-altitude health centers.

Health authorities in Himachal Pradesh monitor regional snakebite cases to improve treatment protocols. The findings provide verified data for medical personnel working in districts where venomous snake species overlap with rural populations.
