You should follow CDC guidelines with regard to your employment environment:
If you are unable to work due to illness, you should use Paid Time Off, as appropriate, until you have recovered. If you do not have enough accrued PTO, we are allowing employees to go into a “negative PTO” balance during this time.
Upon returning to work following an absence due to a personal illness, you may be required to provide a return-to-work clearance from your healthcare provider to Human Resources. You may contact them at firstname.lastname@example.org or 561-300-2410 x504. if you have any questions regarding the return to work process.
