Urban Ticks in Estonia May Pose Greater Infection Risk Than Forest Ticks

Over 3,300 people in Estonia contracted Lyme disease or tick-borne encephalitis last year. Experts warn that ticks living in urban environments may be more dangerous than those found in forests. In some cases, the infection risk may even be higher in cities than in rural areas.

Over 3,300 people in Estonia contracted Lyme disease or tick-borne encephalitis last year – diseases spread by ticks. Although most people associate ticks with forests and rural areas, data shows that the threat also lurks in city parks, gardens and green spaces.

Urban environments increase exposure

In cities, tick habitats are closer to people than ever before. Park benches, children's playgrounds and dog-walking paths are often located on green areas where ticks actively hunt for hosts. Because city dwellers use these areas frequently and often without precautions, the probability of infection may be higher than for someone who regularly walks in forests.

Why urban ticks are more dangerous

According to scientists, the infection rate of urban ticks with Lyme disease bacteria and tick-borne encephalitis virus may be higher than in forest ticks. One reason cited is the high density of rodents living in cities, particularly mice – they are the primary sources of infection for ticks. The more infected host animals living in one area, the higher the infection rate among the ticks themselves.

Health experts recommend that city residents wear long clothing, use tick repellents and check themselves carefully after spending time in green areas. A vaccine against tick-borne encephalitis is available and is considered the most reliable protective measure. If a tick bites, it should be removed as quickly as possible and health should be monitored in the following weeks.
