Nothing. An employee's medical condition is confidential. If there's a chance you came into contact with this person, you will be notified. However, they won't tell you who it is for the safety of that person. Did you know that coronaviruses are one of the many common viruses that cause the common cold? People hear the word coronavirus and they automatically think ventilator or death sentence. While it is true that this strain of the virus (Covid-19) is more to dangerous to some people, the overwhelming majority of people who catch it will have no symptoms or only cold-like symptoms. While the number of positive cases is going up due to more people getting tested, the actual percentage of deaths is going down according to the CDC website.
They can't due it being an violation of hippa if they would, person privacy is the most important thing with this.
Its a violation of hippa to share who/how/what they might have been positive, but if they determined you worked in close proximity for a long person of time, they should send you home to get tested/quarantine. I would think most associates that work together daily, would share this information with each other openly. COVID shouldn't be something you would hid from telling people you had, or tested positive for.
You can do absolutely nothing about it. Employee health records are strictly confidential. Management did its job by informing the employees. Now what they need to do is step up their cleaning and deep clean the whole entire store. If you wish to, get tested.
I do understand your worry. Nobody wants COVID. But the company cannot and will not tell you. If they did, they can be sued big time for breach of privacy.
