At the VFN, we care for children and adults with chronic illnesses in several specialized departments. Therefore, we know from practice that the flu in these patients can have a different and more complicated course.

• Children are more likely to develop complications such as otitis media or sinusitis.
• In people with chronic diseases – such as heart, lung, kidney disease or diabetes – the flu can worsen the course of the underlying disease and significantly prolong the recovery time.
• In more severe cases, antiviral treatment can be used, which is effective against influenza viruses.
• However, antibiotics do not work on the flu, they are only intended to treat bacterial infections.
• Prevention and early protection are therefore key for risk groups.

Protect your health, prevention is key!
