Questions & Answers about Когда у дочки озноб, мама даёт ей тёплый чай и смотрит на градусник каждые полчаса.
Here it means when/whenever in a general, repeated situation.
So this sentence is not talking about one specific moment only. It means something like:
Whenever the daughter has chills, the mother gives her warm tea and checks the thermometer every half hour.
Russian often uses когда + present tense for this kind of habitual meaning.
Russian very often expresses physical conditions with the pattern:
у + genitive + noun
So у дочки озноб literally means something like at the daughter there is chills, but naturally it means the daughter has chills.
This pattern is very common:
- у меня температура = I have a temperature / fever
- у него кашель = he has a cough
- у ребёнка насморк = the child has a runny nose
Using иметь in these everyday health situations would sound unnatural.
