My work tracks all employees who test positive. We’ve had 1300 or so people test positive (it’s a large hospital system). 1 person died and he was a man with extensive health history.You will be okay. I've been working through this entire pandemic. I've been around people with Covid. I may have gotten it in March, but don't know for sure because I couldn't get tested due to low amount of testing in my state. Just wear a mask and wear it correctly. Hopefully the school has students wearing masks as well. Everyone I know who has gotten it survived. Some said it felt like they had a really bad flu and others said they just had a bad headache that week.
