A new study published in the journal Lancet Planetary Health warns that many countries will not be adequately prepared for an increase in snakebites due to venomous snakes migrating to new areas as a result of climate change. Researchers predict that Nepal, Niger, Namibia, China, and Myanmar will be the most affected countries. Low-income nations in South Asia, Southeast Asia, and parts of Africa are expected to experience a rise in snakebite cases.
The study used models to forecast 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 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 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. The World Health Organization (WHO) emphasizes the importance of understanding how climate change impacts snake distribution to better prepare for the potential increase in snakebite incidents.
Researchers warn that snake species will adapt to changing climate conditions and potentially lead to more encounters with humans. Proactive measures must be taken 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.
