A study published in Lancet Planetary Health has warned that many countries will be unprepared for a potential increase in snakebites due to the migration of venomous snakes caused by climate change. The research modeled the geographic distribution of 209 venomous snake species to understand where they will find favorable climate conditions by 2070. While some species will see their habitats expand, others will experience significant range contractions.
Low-income countries in South Asia, Southeast Asia, and parts of Africa are expected to see a rise in snakebite cases as a result of habitat destruction and fragmentation due to agriculture and livestock raising. These displaced snakes are likely to migrate into new areas, potentially putting human populations at risk.
Snakebite envenomation is considered a neglected tropical disease and poses a significant public health challenge. The World Health Organization estimates that millions of people are bitten by venomous snakes each year, resulting in thousands of deaths and permanent disabilities. As climate change continues to impact snake habitats, there is a growing concern about the potential increase in snakebite cases and the need for preparedness measures to mitigate the impact on human health.
The findings of the study emphasize the importance of understanding how climate change affects the distribution of venomous snake species and how this can lead to increased risks for human populations. It is crucial to develop strategies for prevention, education, and treatment to address the growing threat of snakebites in regions vulnerable to snake migrations. By increasing awareness and preparedness, countries can better respond to the changing landscape of venomous snakes and reduce the burden of snakebite envenomation on public health.
