What are my rights in missing work as a precaution with the virus?

Our employer has taken the gallant step of addressing Corornavirus by.............. putting an almost empty bottle of handsanitzer, a spray bottle of clorox and some paper towels on a table. In an office for 100 people.

Woke up with a fever and minor cough this morning after being in an office where everyone was hacking all over.

I freaked out and emailed in sick today and said I might take next week off just to be safe.

I haven't heard back.

I'm concerned my boss will be angry, mocking the severity of the issue or try to retaliate against me for doing this.

I work in a government office, health real estate related.

I have no idea what my rights are in this situation. Anyone?
