Borreliosis / Lyme Disease

Infectious agent transmission

The agent of borreliosis or Lyme disease is Borrelia burgdorferi. Transmission to humans occurs most often by infected ticks that suck human blood.


There are several species of Borrelia bacteria. Depending on the species, different organs are affected in the disease. The first symptom of the disease can be local redness at the site of the bite, which extends and becomes annular. It disappears within a few days or weeks. Among a number of people, the second stage of the disease occurs after a few weeks, months or even years. During the latter,  joints, the nervous system, skin and more rarely the heart may be affected. Cases of Lyme disease can be treated with antibiotics. If the disease is not detected or if the illness is detected too late, it can result in lasting disability.

Geographical distribution and frequency

Lyme borreliosis is the most common tick-borne infection in the northern hemisphere (North America , Europe and Asia ). In Switzerland, about 5% to 30% of the ticks (up to 50% in some parts) are the Borrelia burgdorferi species. The Federal Office of Public Health estimated that in Switzerland, 3,000 persons are diagnosed each year.


Unlike FSME meningitis also transmitted by ticks, there is no vaccine against Lyme disease. To protect yourself against tick bites, you should wear protective clothing, apply insect repellents on skin and clothing, or generally avoid undergrowth. Tick ​​bites often go unnoticed, so it is necessary to examine your body and your clothes after a walk in the woods to detect ticks. Wearing light-colored clothing makes finding ticks easier. Pets such as dogs, cats or horses should also be inspected. Ticks found should be removed as soon as possible. The best to do this is to enter with a fine forceps just above the skin and extract. You should then disinfect the area of the sting.

Seasonal flu

Influenza vaccination is key to prevention

The flu (influenza) is an acute infectious disease known for centuries. It is a respiratory infection triggered by influenza A and influenza B viruses., which circulate especially in winter.

Symptoms of the flu can include high fever, muscle and joint pain, headache and sore throat. The intensity and severity of a flu epidemic varies from one year to another.

People over 65 years and the chronically ill are among those at higher risk. For those people at risk, the flu is not a benign disease. The flu can cause serious complications and loss of autonomy and even death. In Switzerland, the flu alone is the cause of 1,000 to 5,000 hospitalizations and 400-1,000 deaths of elderly every year.

The most effective prevention against influenza is vaccination, using an annual injection. The strains used in the vaccine are determined annually in February by the World Health Organization.
