So you’re fully vaccinated, but you just got word that someone you interacted with has tested positive for Covid-19. What do you do? In a situation that is likely to become more common as the Delta variant spreads, health officials have a few recommendations for how to navigate this tricky situation.

First and foremost, the good news is that new research indicates that less than one percent of fully vaccinated individuals have experienced a breakthrough infection, and in many states, the percentage of fully vaccinated individuals hospitalized for Covid-19 is effectively zero. With that said, it’s still smart to take some cautionary steps if you know you have been exposed.

Monitor for symptoms and get tested 

Although infection potential is low, it’s important to be on the lookout for symptoms and get tested immediately. If you test negative, experts recommend a follow-up confirmation test five to seven days after the first one. If you do begin to experience symptoms like fever, coughing, congestion, fatigue, or shortness of breath, you should self-isolate.

Mask up and take at-home precautions

If you’ve been exposed and are not exhibiting symptoms, it’s still prudent to wear a mask when going out in public and even in the home. If you can, avoid crowded public spaces until you receive a negative result. Make sure you’re washing hands regularly and practice spread prevention measures at home.

Avoid vulnerable friends and family 

Although vaccines provide a very high protection rate, many immune-compromised or elderly individuals can still experience illness. It is a good idea to avoid direct contact with vulnerable or unvaccinated friends and relatives until you receive a negative test result. If you work in a public setting, inform your superior about your exposure so you can follow company procedures regarding exposure.
