How to ask for leave in the group if you have a fever while working in a factory during the epidemic?

If you have a fever while working in the factory and ask for leave in the group as follows:

1. Leader, I have a fever and need to take one day off. Please approve it. Thank you.

2. Leader, I'm really sorry. I have to go to the hospital today due to a sudden fever. I am very weak now and really can't go to work. I would like to take a day off. I hope it will be approved.

3. The leader has a fever of 38.5 degrees Celsius and feels dizzy and weak in limbs. He wants to take a day off. I can't come to work today, so I'm asking for leave.
