## Adenovirus: Everything You Need to Know
According to the Centers for Disease Control and Prevention (CDC),the incubation period – the period between infection and the onset of the first symptoms – is typically two to fourteen days. Patients are contagious when the first signs of illness begin and can remain contagious for up to two weeks, or even longer in some cases.
Does an infection wiht the adenovirus have to be reported?
Table of Contents
In most regions, adenovirus infection is *not* a nationally reportable disease. Tho, some states or local health departments may have specific reporting requirements, especially in cases of severe illness or outbreaks. the Robert Koch institute (RKI) monitors adenovirus activity through its surveillance of acute respiratory infections, but does not require individual case reporting unless part of a specific outbreak investigation.
How can I protect myself and others from the adenovirus?
Five tips to help protect against adenoviruses:
- Wash your hands frequently and thoroughly with soap and water.
- Pay attention to hygiene,especially in shared facilities such as workplaces,schools,and childcare centers.
- Avoid close contact with people who are sick.
- Regularly clean and disinfect frequently touched surfaces such as tables, doorknobs, and electronic devices.
- Wash towels and bedding frequently, especially if shared, using hot water (at least 60°C / 140°F).
Is the adenovirus dangerous?
For most healthy adults, adenovirus infections are mild and resolve on their own, similar to the common cold. However, certain groups are at higher risk of severe illness: people with weakened immune systems, individuals with underlying heart or lung conditions, children, and the elderly. Severe complications can include pneumonia, myocarditis (inflammation of the heart), and encephalitis (inflammation of the brain).
Current Viral Activity (January 9, 2026): Viral infections, including adenovirus, influenza, and COVID-19, continue to circulate. healthcare systems are monitoring trends and providing guidance.
How many people are currently infected with the adenovirus in Germany?
Due to the lack of mandatory reporting, determining the exact number of adenovirus infections in Germany is challenging. The Robert Koch Institute (RKI) monitors the proportion of adenovirus detected in samples submitted for respiratory virus testing as part of its ARE (Acute Respiratory Infections) surveillance system.As of the latest ARE report from week 50 (December 8th to 14th, 2025), adenovirus accounted for approximately 4% of positive samples. In comparison,influenza viruses (A and B combined) represented 34% of positive results.*It’s important to note that these percentages fluctuate throughout the respiratory virus season.* You can find the most up-to-date ARE report here:
