How Long Is Tonsillitis Contagious?
Tonsillitis itself is not contagious, but the viral and bacterial infections that cause it are.
The infection may be contagious for two to three days before symptoms appear and stay contagious until symptoms resolve.
People who take antibiotics for bacterial tonsillitis stop being contagious after about 24 hours.
What Causes Tonsillitis?
Lab results typically take between 24 and 48 hours.
However, steroids of any sort should be used with caution due to their significantside effects.
The tonsils can sometimes become so swollen that they interfere with breathing and swallowing.
This can lead to a more serious condition known as obstructive sleep apnea.
Sleep apnea is a condition where a person stops breathing for brief periods of time while sleeping.
Obstructive sleep apnea is also a leading indication for tonsillectomies in persons with chronic or recurrent tonsillitis.
Avoid sharing food, drinking glasses, water bottles, and utensils.
