At my workplace, we are required to wear face masks throughout the day and to do our best to keep a six foot distance from other coworkers to reduce the spread of COVID-19. A few days ago, I noticed that one of my coworkers came into work carrying a plastic bag and that he quickly threw the bag into a drawer beneath his desk.
Over the past few days, I have noticed that whenever he comes over to talk to me there is the smell of cough drops in the air. This is really worrying me because I suspect that he may be trying to suppress a bad cough that he has due to him having the COVID-19 virus. He coughs for a couple of seconds about every 15 minutes. I believe that the plastic bag he had brought in on Monday morning contained one of those big bags of cough drops.
I am planning to approach my manager today to tell him that I suspect that my coworker has COVID-19, but I am very concerned about my coworker getting angry with me for snitching on him and him then retaliating against me in some way in the future, especially if he is sent home this afternoon. He is not the friendliest guy in the world and I think he is someone who could really benefit from taking an anger management class.
I have considered leaving an anonymous note on my manager's desk informing him that my coworker has been taking a lot of cough drops and thus may have COVID-19, but I'm pretty sure that my manager will know it is from me since I work in close proximity to my coworker. I am thinking that my manager may have to tell my coworker, due to legal/workplace policy reasons, that it is I who suspects him of having COVID-19.
The other option I have is to say nothing about it and to mind my own business, but I think it would be very irresponsible of me not reporting someone who very likely has COVID-19.
Should I notify my manager that a coworker has been taking a lot of cough drops over COVID-19 concerns?
UPDATE
Based on the answers that I have received, I decided not to talk to my manager today about my coworker. I think now that it is in my best interest to just concentrate on my work and to hope that my manager eventually notices him coughing and decides to talk to him about it.
