A comprehensive study by EPFL and Lausanne University Hospital (CHUV) has enabled researchers to map the geographical distribution of ticks in Switzerland for the first time, as well as to determine whether they are carriers of chlamydia. Little is known about these bacteria, but ticks can potentially pass them to humans. The team found that zones conducive to tick proliferation have expanded by 10% over the last decade.
