more than 14% of the world’s population has already contracted it, according to a large study

Ticks have been on the rise around the world for a dozen years. A meta-analysis provided an overall estimate of the epidemiology of Borrelia burgdorferi (Bb) infection in humans and refined knowledge of risk factors. Three regions on the planet are particularly affected and affect the northern hemisphere.

More than 14% of the world’s population has had Lyme disease, the most common tick-borne disease, according to a meta-analysis that compiles studies on the subject. Lyme borreliosis, or Lyme disease, is an infectious disease caused by a bacterium in the complex. Borrelia burgdorferi sensu lato transmitted to humans through the bites of infected ticks.

The Secrets of Lyme Disease, with Professor Benoît Jaulhac

According to the compilation published in the magazine on Tuesday BMJ Global Health, Central Europe has the highest infection rate with 20%. And men over the age of 50 living in rural areas are most at risk. To find out when Lyme disease is common in the world, researchers identified 137 eligible studies – out of 4,196 possible – and pooled data from 89 of them. In 14.5% of the approximately 160,000 participants in total, antibodies directed against the bacterium Borrelia burgdorferi (Bb) were found in the blood. « This is the most comprehensive and up-to-date systematic review of Bb’s global seroprevalence », The study indicates.

After Central Europe, the regions with the highest antibody rates are East Asia with 15.9%, Western Europe with 13.5% and Eastern Europe. East with 10.4%. The Caribbean, on the other hand, has the lowest rate, with only 2%.
