A recent study published in the journal Lancet Planetary Health has shown that many countries will not be prepared for an increase in snakebites due to climate change. Researchers predict that countries such as Nepal, Niger, Namibia, China, and Myanmar will be most affected by the influx of venomous snake species from neighboring regions.
The study utilized models to predict the potential geographic distribution of 209 venomous snake species by 2070, taking into account climate conditions. Some species are projected to see their range decrease due to factors like habitat loss and changes in temperature, while others, such as the West African gaboon viper, are expected to see their range expand significantly. Habitat loss due to land conversion for agriculture and livestock is a major contributor to the displacement of snakes.
Snakebite envenomation is classified as a neglected tropical disease by the World Health Organization (WHO), which estimates that millions of people are bitten by venomous snakes each year, resulting in thousands of deaths and cases of permanent disability. The WHO emphasizes the importance of understanding how climate change impacts snake distribution in order to better prepare for potential increases in snakebite incidents.
Researchers stress the need for proactive measures to address the risks posed by venomous snakes moving into new territories. With proper awareness and preparation, countries can better mitigate the impact of snakebites on public health.
