Venomous Snake Migration: Study Warns of Potential Rise in Snakebite Cases Due to Climate Change
A study published in the journal Lancet Planetary Health warns that many countries will not be prepared for an increase in snakebites as a result of venomous snakes migrating to new areas due to climate change. Researchers predict that Nepal, Niger, Namibia, China, and Myanmar will be most affected by the influx of venomous snake species from neighboring regions. Low-income countries in South Asia, Southeast Asia, and parts of Africa are expected to see a rise in snakebite cases.
The study utilized models to predict the potential geographic distribution of 209 venomous snake species by 2070, taking into account climate conditions. While some species will experience range contractions, others, such as the West African gaboon viper, are projected to see their range increase significantly. Habitat loss due to land conversion for agriculture and livestock is a major factor contributing to the displacement of snakes.
Snakebite envenomation is classified as the top neglected tropical disease by WHO, with millions of people being bitten by venomous snakes each year resulting in thousands of deaths and cases of permanent disability. Researchers emphasize the importance of understanding how climate change impacts snake distribution to better prepare for the potential increase in snakebite incidents.
With proper awareness and preparation, countries can better mitigate the impact of snakebites on public health. The World Health Organization (WHO) estimates that millions of people are bitten by venomous snakes each year and stresses the need for proactive measures to address the risks posed by venomous snakes moving into new territories.
