Ticks transmit rare bacterial strains – increased risk for vulnerable elderly people

A concerning medical discovery is drawing attention to the increased risks posed by ticks, particularly for elderly people. Researchers have identified a rare strain of the bacterium responsible for Lyme disease in a new geographical area, raising alarm bells among specialists.

This unusual strain has been detected for the first time in the region and displays characteristics that make it especially dangerous. According to doctors, the new bacterial variant can produce more severe clinical manifestations than the classic forms of Lyme disease, posing a particular risk to older adults with compromised immune systems.

Impact on the elderly population

Older people are especially vulnerable to tick-borne infections due to the weakening of the immune system that occurs through the natural ageing process. Symptoms of Lyme disease can include fever, headaches, extreme fatigue and characteristic skin rashes, which in elderly patients may be mistaken for other age-related conditions.

Specialists emphasise that early detection and prompt treatment are essential for preventing serious complications, which can include cardiac, neurological and joint problems. For older adults who spend time outdoors or live in rural areas, protective measures become all the more important.

Essential preventive measures

Doctors recommend following a few simple protective guidelines: wearing light-coloured clothing to make ticks easier to spot, using insect repellent, and carefully checking the entire body surface after outdoor activities. For elderly individuals, assistance in checking hard-to-reach areas can be crucial.

This discovery highlights the need for continuous monitoring of the progression of vector-borne diseases and for adapting prevention strategies in line with newly identified risks, particularly in the context of climate change, which is favouring the expansion of tick habitats.
