Their bites frequently cause local effects while rarely causing systemic envenoming, that may include acute kidney injury and coagulopathy. There are 3 species of genus Hypnale including H. hypnale, H. zara and H. nepa from which latter two are endemic to Sri Lanka. Virtually all studies on HNPV bites in Sri Lanka are focused on adults except two studies in paediatric group. The aims of this study were to describe the epidemiology and clinical manifestations of HNPV bites in a group of children admitted to a tertiary care hospital in Sri Lanka.<h4>Methodology/principal findings</h4>This was a prospective observational study carried out in Teaching HoPLoS neglected tropical diseasese0011013https://www.ebi.ac.uk/biostudies/studies/S-EPMC9822102biostudies-literatureEpidemiological and clinical features of hump-nosed pit viper (Hypnale hypnale and Hypnale zara) envenoming in children.PMC9822102Ranathunga PEANKularatne SAMRathnayaka RMMKNfalseEpidemiological and clinical features of hump-nosed pit viper (Hypnale hypnale and Hypnale zara) envenoming in children.<h4>Background</h4>Bites by the hump-nosed pit vipers (HNPV) of the genus Hypnale are the commonest type of venomous snakebites in Sri Lanka.
