Lyme disease is the most common tick-borne illness in Europe and North America 

Lyme disease was first named nearly 50 years ago in Lyme, Connecticut, but the tick-borne disease is now found around the world 

A new study published in BMJ Global Health estimates that 14.5% of the world’s population has, at some point, been infected with Lyme disease 

It can cause short-term symptoms including a skin rash, fever, headache, and fatigue—as well as long-term ones 

The scourge also appears to be getting worse. Lyme prevalence has doubled from 2010 to 2021, compared to 2001 to 2010

“[Lyme disease] has become the most common tick-borne zoonotic disease worldwide,” the researchers wrote 

There is a need for preventive measures, which necessitates understanding the dynamics of tick-borne disease transmission 

Higher temperatures and longer springs and summers increase ticks’ range and the amount of time people spend outside
