#1：What’s the difference between a cold and the flu?

  Cold symptoms usually take a few days to appear, and flu symptoms appear more quickly.

  If you have a cold, you can expect the virus to work its way out in about a week to 10 days. If you have the flu, this virus may take the same amount of time to fully disappear, but if you notice symptoms are getting worse after day five, or if they’ve not disappeared in a week, you may have developed another condition.

The common cold is a viral infection in your upper respiratory tract. Viruses cannot be treated with antibiotics. In most cases, viruses like the cold just need to run their course. You can treat the symptoms of the infection, but you can’t actually treat the infection itself.

The average common cold lasts anywhere from seven to 10 days. Depending on your overall health, you may have symptoms for more or less time. For example, people who smoke or have asthma may experience symptoms longer.

If your symptoms do not ease or disappear in seven to 10 days, you should make an appointment to see your doctor. Symptoms that don’t go away could be a sign of a bigger problem, such as the flu or strep throat.

#2;Home remedies

The most effective and common home remedies for a cold include gargling with saltwater, rest, and staying hydrated. Some research also shows that herbs like echinacea may be effective at reducing symptoms of a cold. These treatments don’t cure or treat a cold. Instead, they can just make symptoms less severe and easier to manage.
