Their symptoms may be very much alike, but typically, based on our common sense, we know:
- It takes a lot longer to recover from a flu than from a cold.
- A flu usually brings us the body ache, fever, and significant malaise.
- A flu, if not treated properly, can easily cause complications such as pneumonia or bronchitis.
A cold rarely has symptoms such as fever or muscle ache. The recovery time of a common cold is about a week while it may take a couple of weeks to recover from a flu.
Symptoms of a common cold:
Relatively minor symptoms such as cough, sore throat, or runny nose. High fever is rare. It takes about 2 to 5 days to recover from a cold.
Symptoms of a flu:
In addition to sore throat, runny nose, or cough, it may be accompanied by high fever, headache, muscle and joint pain, and significant malaise and weakness. It typically takes about 1 to 2 weeks to recover from a flu.
For a common cold, the treatment is mostly self-healing as a cold normally has lower possibility to cause complications.
A flu, however, may require a prescription of the antiviral drugs. There is a higher chance for complications to arise such as pneumonia, sinusitis, bronchitis, otitis media, myocarditis and the like.
