Lyme Disease Cases 2025: Rising Rates & What to Know

Lyme Disease Cases Surge across Germany in 2025, Raising public Health Concerns

A significant increase in Lyme disease and tick-borne encephalitis (TTE) cases has been reported across Germany in 2025, prompting health officials to urge vigilance. Data released on December 29th reveals a dramatic rise in infections, with several states experiencing record-high numbers.

Saxony Leads the Increase

The state of saxony has been particularly affected, recording 2,623 cases of Lyme disease by the end of December. This represents approximately 1,000 more infections than were reported during the entirety of the previous year, which saw 1,626 cases. In 2023, Saxony registered 1,484 cases, demonstrating a clear upward trend. According to reports from the State Research Institute (LUA), the surge is substantial and warrants close monitoring.

Did you know? – Ticks don’t jump or fly. They crawl onto hosts, frequently enough from grasses or shrubs. Thorough tick checks are crucial after outdoor activities.

TBE Cases Also on the Rise

Alongside Lyme disease, cases of tick-borne encephalitis (TTE) are also increasing. Last year, Saxony recorded 47 cases of TTE, a notable jump from the 63 cases reported in the prior year, and a significant increase compared to the 34 cases registered in 2023. Fortunately, a vaccine is available for TTE, offering a preventative measure against the disease.

Understanding Lyme Disease and TTE

Both Lyme disease and TTE are transmitted to humans through the bite of infected ticks.While TTE can initially present with flu-like symptoms and perhaps lead to nervous system complications, Lyme disease frequently enough manifests as fatigue, loss of performance, difficulty concentrating, muscle and joint pain, and fever. A characteristic red circle frequently enough appears around the site of the tick bite.If left untreated, Lyme disease can escalate to inflammation of the joints, heart muscle, and nerves. Lyme disease is typically treated with antibiotics.

Pro tip – when removing a tick, use fine-tipped tweezers to grasp it as close to the skin as possible and pull upward with steady, even pressure. Avoid twisting or crushing the tick.

Peak Tick Season and Activity

The period from March to September is considered peak tick season in Germany, with activity levels directly correlated to temperature.The Robert Koch Institute (RKI) indicates that ticks become active when temperatures reach around six degrees Celsius.

Nationwide Trend

The increase in Lyme disease cases isn’t limited to saxony. Other German states are also reporting significant rises. In Berlin, epidemiologists have counted 1,406 cases as of mid-December – the highest number recorded as mandatory laboratory reporting began in 2013. Bavaria has reported 5,469 cases of Lyme disease by mid-December, an increase of approximately 1,500 cases compared to the same period last year.

The escalating numbers underscore the importance of preventative measures and early detection in combating these tick-borne illnesses.

Expanded News Report:

Why: The surge in Lyme disease and TTE cases in Germany during 2025 is attributed to a combination of factors, including milder winters allowing for increased tick survival and activity, and potentially changes in land use or animal populations that contribute to tick proliferation. the RKI notes that tick activity is directly correlated to temperature, with ticks becoming active when temperatures reach around six degrees Celsius.
