Climate change isn't just warming the planet — it's changing the skin diseases doctors see every day. A sweeping new study from the International League of Dermatological Societies (ILDS), presented at the European Academy of Dermatology and Venereology Congress, found that more than 40% of WHO member countries reported climate-related shifts in the prevalence or severity of skin diseases. The impact is far from evenly distributed: low- and middle-income countries are feeling it most, driven by weaker healthcare infrastructure and limited access to dermatologists.

The study surveyed 136 of 194 WHO member countries and found that regions like the Western Pacific, Eastern Mediterranean, and South-East Asia reported the highest rates of climate-linked skin disease changes. Meanwhile, only 16% of European countries flagged similar concerns. Experts warn that rising temperatures, shifting rainfall patterns, and expanding vector habitats are fueling conditions that health systems — especially in resource-limited settings — may not be equipped to handle.

By the Numbers:

• 55.6% of low-income countries reported climate-related skin disease changes
• 52.5% of lower-middle-income countries reported the same
• 28.3% of high-income countries reported changes — less than half the rate of low-income nations
• Top conditions: heat rash (81%), inflammatory skin diseases (75.9%), infectious disease shifts (62.1%), vector-borne diseases (50%)

Why it matters: Dermatologists on the front lines are already seeing the effects — from more frequent disease flares to unfamiliar infections creeping into new geographies. Addressing these disparities requires better global surveillance, locally tailored solutions, and clinicians prepared to recognize a shifting disease landscape.
