At the beginning of a viral infection, like the cold and flu, you can be contagious while showing no symptoms at all for a day or even two. However, the rule of thumb is that after having a fever with the flu and then it subsides, once you have gone a full 24 hours after that without a fever (when taking no fever-reducing medicines), you are considered no longer contagious and can go back into public again.
yes it can be contagious
Yes. You are contagious with low grade fever. Some times you are contagious without fever also. Some times you get asymptomatic infections.
The fever itself is not contagious -- the virus causing a fever is, though, and when you have a fever from a virus, you are contagious with that virus and should stay away from people if you can.
no
Yes, the glandular fever is very contagious. It is generally transmitted by saliva. It is known as "the kissing disease" or "mono."
A fever by itself is not contagious. Fever is a generic symptom and sign that only says the body is fighting something. It is what is causing the fever that MAY be contagious.Contagious WITH fever as well:Measles, Mumps, Rubella (MMR vaccine has been controlling these)Strep, and MeningitisFlu, Bronchitis, Upper Respiratory Infection, viral or bacterialThe PlagueEbola virusAs just ONE example of a non-contagious problem that can produce fever:inflammation in the body, from ANY cause, such as cancer, which is never contagious
You are still contagious for 24 hours after the last time you had a fever WITHOUT the use of fever reducing medications.
