Common cold
Symptoms
By Mayo Clinic staff
Symptoms of a common cold usually appear about one to three days after exposure to a cold-causing virus. Signs and symptoms of a common cold may include:
* Runny or stuffy nose
* Itchy or sore throat
* Cough
* Congestion
* Slight body aches or a mild headache
* Sneezing
* Watery eyes
* Low-grade fever
* Mild fatigue
The discharge from your nose may become thicker and yellow or green in color as a common cold runs its course. What makes a cold different from other viral infections is that you generally won’t have a high fever. You’re also unlikely to experience significant fatigue from a common cold.
When to see a doctor
For adults — seek medical attention if you have:
* Fever of 103 F (39.4 C) or higher
* Fever accompanied by sweating, chills and a cough with colored phlegm
* Significantly swollen glands
* Severe sinus pain
For children — in general, children are sicker with a common cold than adults are and often develop complications, such as ear infections. Your child doesn’t need to see the doctor for a routine common cold. But seek medical attention right away if your child has any of the following signs or symptoms:
* Fever of 103 F (39.4 C) or higher in children age 2 or older
* Fever of 102 F (38.9 C) or higher in children ages 6 weeks to 2 years
* Fever of 100 F (37.8 C) in newborns up to 6 weeks
* Signs of dehydration, such as urinating less often than usual
* Not drinking adequate fluids
* Fever that lasts more than three days
* Vomiting or abdominal pain
* Unusual sleepiness
* Severe headache
* Stiff neck
* Difficulty breathing
* Persistent crying
* Ear pain
* Persistent cough
If symptoms in a child or an adult last longer than 10 days, call your doctor.
