Cold and Flu Symptoms
What are the differences between cold symptoms and flu symptoms?
Cold and flu symptoms can sometimes overlap. If you’re trying to determine if your symptoms are a cold or the flu, check out our info on cold and flu symptoms and how to tell the difference between a cold and flu.
What are the symptoms of a cold?
Cold symptoms can last from 2 days to 2 weeks, but most people recover in a week to 10 days. Symptoms of the common cold usually begin 2 to 3 days after infection and often include:
- Sore throat
- Mucus buildup in your nose
- Difficulty breathing through your nose
- Swelling of your sinuses
TIP! The common cold does not generally produce fever in adults, however fever can often be found in children with colds and can climb to 102ºF in infants and young children.
What are the symptoms of the flu?
The flu usually comes on suddenly, though people can host the flu virus for 1-4 days before symptoms begin to emerge. People who have the flu often feel some or all of these symptoms:
- Fever or feeling feverish/chills*
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Vomiting and diarrhea (more common in children)
* It’s important to note that not everyone with flu will have a fever.
How does a cold feel different from the flu?
Cold and flu symptoms can sometimes feel similar. The key is in understanding how a cold feels different from a flu. A fever (generally between 100 and 102) usually accompanies the flu and lasts 3 to 4 days. It is rare to develop a fever from a cold, though more common in children. Severe headaches and body-aches often accompany the flu, while these symptoms are slight or non-existent with colds.
Additionally, the flu usually causes exhaustion, which is not a general symptom of the common cold, despite feeling a bit run-down. A stuffy nose, sore throat and sneezing more often indicate a cold than they do the flu.
In most cases, cold and flu symptoms can be relieved by taking an OTC cold and flu medication, like Contac Cold + Flu, and drinking plenty of water.
