Tonsillitis: Increasing transmission in Denmark
The number of cases of tonsillitis in Denmark has increased significantly in 2025. According to TV2 News, infections continue to rise, and there are no signs that the peak has been reached. At the same time, data from the Statens Serum Institut (SSI) show that around 600,000 Danes visit their doctor each year with a sore throat, of which 200,000 cases are caused by group A streptococcal bacteria (GAS).
Rising transmission in the winter season
The current rise in throat infections coincides with a general increase in respiratory infections. Figures from SSI show that from November 2024 to March 2025 there has been a higher incidence of streptococcal infections. This is partly because more people stay indoors during the winter months, where infections spread more easily.
Symptoms of tonsillitis
The most common symptoms of tonsillitis include:
- Sore throat and difficulty swallowing
- Fever above 38°C (100.4°F)
- Red and swollen tonsils, possibly with white spots
- Hævede lymfeknuder på halsen
- Fatigue and general malaise
Treatment of tonsillitis
Treatment depends on whether the infection is caused by a virus or bacteria:
- Virus: The body fights off the infection on its own, and treatment consists primarily of supportive measures such as rest, fluids and pain relief.
- Bacteria (GAS): Antibiotic treatment may be necessary to avoid complications such as peritonsillar abscesses or rheumatic fever.
How is tonsillitis transmitted?
The disease is spread via droplet infection, i.e. coughing, sneezing or close contact with an infected person. To reduce the risk of infection, it is recommended that you:
- Washing hands frequently
- Avoid sharing cutlery, cups and toothbrushes
- Cover your mouth and nose when you cough or sneeze
