The flu is probably the most common viral illness in northern latitudes. Many people put up with the risk of contracting it and do without a vaccination. But influenza can have serious consequences for certain population groups. If you belong to one of these groups, you should consider vaccination or other protective measures. The best thing to do is to consult your trusted doctor.
People with chronic lung disease
If you have chronic lung diseases such as asthma or chronic bronchitis, you are particularly at risk when the flu spreads. The flu also weakens your respiratory tract, so that bacteria have an easy time of it and can trigger pneumonia, for example. This can make chronic lung diseases significantly worse.
The flu in people over 65
Many people accept that the flu season inevitably leads to illness each year. However, after a certain age it may be appropriate to protect yourself against infection with a vaccination. The Robert Koch Institute warns that there is a risk, especially in the older population groups, that the flu will be fatal.
People with weakened immune systems
You are at greater risk of the flu if you have immunodeficiency diseases or if your immune system is suppressed from medical treatment. Inadequate nutrition also increases the risk of infection.
