My friend is ill and has a fever. What should I do? Say what?

My answer: if you are sick, treat it first. For physical reasons. Measure the temperature with a thermometer. From Baidu

If you have a fever, take antipyretics and ask him if he is allergic to anything. From Baidu

And wet the towel with cold water and apply it to your forehead. If possible, wet the towel with cold water and wipe the whole body to cool down.

If it is serious, go to the hospital.

For spiritual reasons. If the patient is upset because of the disease, comfort him: for example: 1. Nothing, just have a rest. I'll stay with you. If you need anything, call me.
