Both flu and colds are respiratory illnesses that block your airways and cause coughing. Flu causes the complication of lung infection pneumonia. If you have fever above 102 degrees, persistent cough and chills, difficulty in breathing, or chest pain while coughing, you need to call the doctor immediately.

Symptoms of Common Cold

Usually, cold symptoms start with sore throat that goes off after a few days. Runny nose, nasal symptoms and congestion flow with a cough by fifth day. In adults, fever is rare. But kids are more prone to have fever followed by cold. The nose also teems with watery secretions for the first couple of days. Later on, they get darker and thicker. Don’t panic if you have dark mucus as it is not the sign of developing sinus infection or other bacterial infection.  A lot of viruses are likely to cause cold symptoms.

Longevity

Usually, symptoms of cold could stay for over a week. During the initial 3 days, cold symptoms are usually contagious. Hence, your cold could be passed on to others. So, you should take rest and stay at home. If symptoms of cold don’t improve after a week, you may need to take antibiotics to deal with bacterial infection. You may, sometimes, confuse such symptoms with sinus infection or hay fever. If cold symptoms start immediately and improve after a week, it is cold, not allergic reaction. If cold symptom doesn’t get better within a week, ask your doctor to find out if you have sinusitis or allergy.

Symptoms of Flu

Symptoms are more severe as compared to that of cold and they come quickly. Some of the common flu symptoms are fever, sore throat, muscle aches, headache, muscle soreness, cough, congestion, and even swine flu if it is associated with diarrhea and vomiting.

Most of the symptoms of flue improve gradually within 2 to 5 days but it is rare to feel for a week. Pneumonia is one of the common complications of flu, especially in elderly, young people or anyone with heart or lung problems. If you feel breathing issues, ask your doctor. Another potential problem is fever that comes back again after giving relief for a few days.

Like viruses of cold, flu viruses also come in via mucous membranes of eyes, nose and mouth. By touching one of such areas, you may infect yourself with a virus every time. So, make sure to keep your hands clean any wash them frequently to avoid both cold and flu symptoms.
