Symptoms of a common cold usually appear one to three days after exposure to a cold-causing virus.
Signs and symptoms, which can vary from person to person, might include:
Runny or stuffy nose Sore throat Cough Congestion Slight body aches or a mild headache Sneezing Low-grade fever Generally feeling unwell (malaise)
The discharge from your nose may become thicker and yellow or green in color as a common cold runs its course. This isn’t an indication of a bacterial infection.
For adults — seek medical attention if you have:
Fever greater than 101.3 F (38.5 C) Fever lasting five days or more or returning after a fever-free period Shortness of breath Wheezing Severe sore throat, headache or sinus pain
For children — in general, your child doesn’t need to see the doctor for a common cold. But seek medical attention right away if your child has any of the following:
Fever of 100.4 F (38 C) in newborns up to 12 weeks Rising fever or fever lasting more than two days in a child of any age Symptoms that worsen or fail to improve Severe symptoms, such as headache or cough Wheezing Ear pain Extreme fussiness Unusual drowsiness Lack of appetite
