Whether you have a cold, the flu or any number of common illnesses, you could easily be spreading your germs to countless friends, family members and strangers without even realizing it. However, if you are aware of when you are most contagious with these illnesses, you can cut down on the number of people you expose to your germs and hopefully avoid infecting at least a few other people.
Sometimes it's impossible to prevent spreading your germs because you are contagious before you even know you are sick. Other times it's a little easier to know when to stay away from others (fevers are typically a good sign that you are contagious). Find out more about when you might be contagious when you have a cold or the flu.
