Helping make an effective Covid exposure warning network

With high Omicron transmissibility, exposure alerts assume a higher priority IMHO. If you are an iPhone user (I don’t know about other platforms) don’t forget that you can turn on the built-in exposure alert system. And if you turn Covid-positive, it will serve others well if you remember to indicate it in the iPhone’s exposure monitoring system. you’ll find it in the Settings app under the Exposure Notifications section.
