An epidemiological study of snakebites from rural Haryana

Abstract

Background: Snakebite is a frequently encountered medical emergency faced mainly by rural populations. It is a significant public health problem in many parts of the world, especially in South Asian countries. Aims: This study aimed to analyze the epidemiological aspects of snakebite among human snakebite victims admitted to the emergency ward of a tertiary care teaching hospital between 2010 and 2012 in rural Haryana. Additional objectives were to study other factors that have a bearing on the outcome of snakebite. Methods: In this cross-sectional study, lists of addresses and contact numbers were prepared for all the snakebite cases admitted to the emergency ward of Maharishi Markandeshwar Institute of Medical Science & Research (MMIMSR), Mullana, Haryana, between June 2010 and May 2012. The subjects eligible for the study were then interviewed to gather epidemiological information. Necessary clinical data were obtained from records. Results: The majority or 49.4% of the victims were in the age group of 31-45 years, followed by 32.91% in the age group of 16-30 years. Of the victims, 20.3% were illiterates. A majority (48.1%) of the victims were manual laborers and farmers. The foot was the most commonly (62.03%) involved part of the body. Most (48.10%) of the snakebite incidents occurred while the victims were doing agricultural work. Further, 64.56% cases were reported during the monsoon season and 41.77% victims were bitten in the bush. Among the subjects, 60.76% received first aid at the site of incident, and 20.25% of them sought hospital care after consulting the traditional healers (ozhas). Time lapsed for seeking hospital treatment was less than 4 h in 55.69% of the cases. The overwhelming majority (83.54%) of snakebite victims recovered after the treatment. Conclusion: This study highlights the need for improving community education, prompt transport of bitten patients to medical care, capacity-building of medical staff at all levels, and availability of anti-snake venom in rural health facilities to reduce snakebite deaths.
