"The decision about whether or not to go to work really needs to be a personalized decision based on how effective you'll be at doing your job", says Dr. Daniel Alley, of Abilene Regional Medical Center.
When this happens, doctors say you should really ask yourself one thing.
"The question is: are you infectious or not? Can you give what you have to somebody else?", explains Dr. Alley.
And it doesn't take a medical professional to figure that out.
"That is typically fairly easy to determine. If you've been sick with a cold, and have a sore throat, runny nose and a cough, about the time you start to feel better, is about the time you're not longer contagious", Dr. Alley tells us.
But what if you're the healthy one? Going into the germ-filled office full of coughing coworkers?
"If you're around someone with a cold and you want to avoid getting a cold, keep your hands way from your face. If you have to rub your eyes or itch your nose, make sure you was your hands before you do that. That will break the transmission cycle and help to keep as many people healthy as possible", Dr. Alley suggests.
Whether you're feeling under the weather and the thought of clocking in puts you over, or you're as healthy as can be, and intend stay that way--Dr. Alley says they key is always prevention.
