The cobras (genus Naja) of Myanmar: An updated species list with information on identification, distributions, and medical importance

The cobra diversity of Myanmar has long been a source of confusion, complicating public health responses to snakebites resulting from this medically important genus. By integrating distributional data, natural history information, and clinical evidence, we clarify the composition and distribution of Myanmar’s cobra fauna and evaluate the implications for envenoming and snakebite management. We confirm the presence of five cobra species (Naja fuxi, N. kaouthia, N. mandalayensis, N. siamensis, and N. sumatrana) in Myanmar through voucher specimens and/or diagnostic photographic records and identify one additional unconfirmed species (N. sagittifera) that may occur in the country based on distributional proximity. Encounter records showed significant within-year temporal variation, with reports peaking in December and during the dry season. Because data derive from opportunistic citizen science submissions, these patterns likely reflect seasonal differences in detection and human activity rather than biological seasonality. Differences from wet-season peaks reported elsewhere highlight the importance of sampling framework in shaping apparent temporal trends. Review of clinical and toxicological information shows that only one species is represented in locally produced antivenom, raising concern about limited cross-neutralization for other cobra species in the country. Traditional practices remain common in many communities and include harmful methods that delay access to medical care or worsen injuries. Clinical evidence demonstrates that neurotoxicity, respiratory failure, and localized tissue destruction are the principal complications of cobra envenoming, often requiring antivenom therapy, airway support, mechanical ventilation, infection management, and surgical intervention in severe cases. The broader-than-recognized diversity of cobras in Myanmar, combined with high encounter probabilities, synanthropic tendencies, and gaps in public awareness, continues to hinder effective management of snakebite. Improved community education, expanded venom and antivenom research, and timely access to appropriate medical care are essential for reducing the burden of cobra envenomation in Myanmar.
