Hi, I have been sick for a few days. Home from work today. I work at a nursing home. Many residents and some coworkers have something. They just call it an upper respiratory thing . I have a very painful sore throat, some coughing, some mucous draining down throat, when sniffling mainly, and fatigue. Also laryngitis. is this contagious? Does it have a specific name? How best to treat it. (I have low income and no insurance. Thank you.
