Symptoms are body changes that tell you something’s wrong. They are a way for your body to let you know that an infection is developing or that you are sick. It’s important to tell your doctor about your symptoms because they will help them figure out what the problem is and how to treat it. Think of symptoms like clues in a detective mystery. The more symptoms you have, the easier it will be for your doctor to solve the case!
Viruses that cause the common cold are spread when airborne droplets — coughing or sneezing into the air — land on surfaces such as toys, doorknobs and hands that you then touch. The viruses may then enter your eyes, nose or mouth. You can avoid getting a cold by washing your hands often with soap and water for 20 seconds or using an alcohol-based hand sanitizer. Avoid kissing, hugging and shaking hands with people who are ill. Also, avoid breathing in air that has been sprayed by someone who is coughing or sneezing, and do not go into the house of anyone who is ill.
Symptoms of the common cold typically begin with a sore throat, followed by a runny nose. You may then develop a cough, which produces mucus that causes congestion in the nose and ears. As the congestion builds up, sneezing becomes more frequent. Some people may develop a low-grade fever at this stage. The nasal congestion also clogs sinuses, producing pressure that can lead to a headache.
