How to ask for leave when the epidemic is afraid of the sun?

The reasons for taking time off for fear of sun exposure are as follows:

1. I was diagnosed as COVID-19 positive, with a splitting headache, hoarse voice and weak body. I'm afraid I can't work normally anymore. I'm going to be isolated at home for a while in order to recover.

2. Because people around us have been infected with novel coronavirus recently, and there are elderly people at home, the resistance is still relatively weak, and it is even more difficult to prevent the epidemic virus.
