COVID-19 vaccines and boosters offer our best protection against COVID-19, the Omicron variant, and its subvariants.
If you’re feeling even mildly ill, please stay home from work, avoid crowds, and get tested. Testing — especially before and after traveling or going to an event or meeting — is a great way to ensure you’re not inadvertently passing on the disease.
Masks are effective at preventing transmission of COVID-19 and other respiratory viruses. You may want to consider wearing masks indoors, in large crowds, and with people from outside of your household.
When meeting people from outside your household, gather outdoors if possible. If not, open windows and use fans to improve ventilation.
Wash or sanitize hands frequently.
