Symptoms of the common cold include congestion, cough, sneezing, watery eyes and a runny or stuffy nose, according to Mayo Clinic. As a cold runs its course, nasal discharge may turn from thin and clear to thicker and green or yellow. This is perfectly normal and usually not a sign of any other problem.
Colds are different from flu because they usually do not come with a high fever. Flu sufferers also suffer from marked fatigue while those who have a cold do not. Cold sufferers may also have a headache, slight body aches and a low-grade fever.
Colds can happen at any time of the year, but are more prevalent during the fall and winter months. There are more than 100 viruses that cause a cold and these viruses enter the body through the eyes, nose or mouth. it can also spread through hand-to-hand contact, which is why people should frequently wash their hands.
Children are most susceptible to the common cold because they have not developed an immunity to cold viruses, notes Mayo Clinic. Although most colds come and go without incident, some complications may occur. Colds sometimes develop into an ear or sinus infection, strep throat, pneumonia and bronchitis.
