can a cold be contagious without fever
Contagious factor It's contagious as long as fever and cough are present. While prednisone is helpful in decreasing symptoms' severity, it doesn't prevent your child from spreading the illness as long as he has symptoms. So keep him home until the barking subsides.
The contagious period for the flu is similar. A study found youâre most contagious during a 2-3 day period after the on-set of symptoms. But just like a cold, you can still spread influenza during the entire time youâre sick - anywhere between 2 and 10 days. Itâs possible to infect others one day before you feel any symptoms like a high fever, muscle aches, sinus problems and stomach issues.
