Dangerous Free-Living Amoebae Spreading Globally as Climate Warms, Scientists Warn
Scientists are sounding the alarm about free-living amoebae becoming an increasing global health threat due to climate change and outdated water systems. Some species can cause deadly infections and survive harsh conditions, including standard water disinfectants like chlorine.
Global Amoeba Threat Growing
Free-living amoebae are emerging as a global health concern, fueled by warming temperatures and outdated water systems. While many are harmless, some can cause deadly infections and even protect other dangerous microbes.
Why They're Particularly Dangerous
According to researcher Longfei Shu of Sun Yat sen University, "What makes these organisms particularly dangerous is their ability to survive conditions that kill many other microbes. They can tolerate high temperatures, strong disinfectants like chlorine, and even live inside water distribution systems that people assume are safe."
This resilience means that standard water treatment methods may not always be enough to eliminate them, especially in older or poorly maintained systems.
Climate Change Factor
Rising global temperatures are expected to make the problem worse, as many of these amoebae thrive in warm conditions, so as water temperatures increase, they are likely to expand into new regions where they were once uncommon.
Call for Action
To address the growing threat, researchers are calling for a broader, more coordinated response using a One Health approach, which brings together experts in human health, environmental science, and water management. Improving surveillance systems is a key priority, along with developing faster and more accurate diagnostic tools.
