hohes Fieber

You will almost always use this with the verb haben (to have). For example, Ich habe hohes Fieber. If you are talking about someone else, you'd say Er hat hohes Fieber. You can also use it with bekommen (to get) if the fever is just starting. It's a very straightforward collocation. You don't need fancy grammar to make this work. Just pair the noun phrase with a simple verb and you're good to go.

Use this when you need to justify an absence. It works perfectly when calling your boss or your child’s school. It’s also the first thing you’ll tell a doctor or pharmacist. If you're texting a friend to cancel dinner, hohes Fieber is the ultimate 'get out of jail free' card. No one expects you to show up to a party when you're burning up. It’s a serious but common medical description.

Don't use this if you just feel a bit 'off' or slightly warm. For a mild temperature, Germans use erhöhte Temperatur (elevated temperature). If you use hohes Fieber for a tiny sniffle, your German friends might get overly worried and try to call an ambulance for you. Also, avoid using it metaphorically like 'Bieber Fever'—Germans don't really use Fieber for excitement in the same way English does.

Germans have a specific relationship with fever. While some cultures reach for medicine immediately, many Germans believe a moderate fever is the body healing itself. However, once it becomes hohes Fieber, the 'Wadenwickel' come out. This is a traditional home remedy involving wet, cool towels wrapped around the calves. If a German grandma hears you have hohes Fieber, she will likely insist on this treatment before letting you take a pill.

You might hear leichtes Fieber for a mild fever. If the fever is dangerously high, someone might say sehr hohes Fieber. If you are feeling feverish but haven't measured it yet, you can say ich fühle mich fiebrig. In a medical context, a doctor might ask if the fever comes in waves, but for everyday life, hohes Fieber is your go-to phrase.
