The common cold, also well known as a viral upper respiratory tract infection, is an infectious disease that can be caused by a number of different types of viruses, primarily caused by picornaviruses (including rhinoviruses) or coronaviruses. A cold virus enters your body through your mouth or nose, but it's likely you also had a "hand" in your own illness. The viruses that ground a cold attack the lining of the nose and throat, making these areas become inflamed. As they turn out to be inflamed they begin producing more mucus, ensuing in a runny nose and sneezing. The virus can multiply through droplets in the air when someone who is sick coughs, sneezes or talks. But it also spreads by hand-to-hand contact with someone who has a cold or by using shared objects, such as utensils, towels, toys or telephones. Touch your eyes, nose or mouth after such contact or exposure, and you're likely to "catch" a cold. Symptoms of a common cold comprise sore throat, runny nose, nasal congestion, sneezing and cough; sometimes accompanied by 'pink eye', muscle aches, fatigue, malaise, headaches, muscle weakness, and/or loss of appetite.

The symptoms of a cold usually resolve after about one week, but can last up to 14 days . You can normally treat the symptoms of a common cold at home. There is no treatment for a cold and antibiotics are not agreed because antibiotics do not work against viruses. Some of the measures to prevent this problem are to wash hands thoroughly before eating, preventing the use of the same towels or eating utensils as someone who has a cold. You shouldn't drink from the same glass, can, or bottle as anyone else. Do not pick up other people's used tissues. Dispose of used tissues right away, and then wash your hands cautiously. Do not pick up other people's used tissues. Keep the room at a contented temperature, but make sure that fresh air is circulating. Smoke irritates the nose and throat. Try to stay away from people who smoke and avoid smoke-filled environment. If you are a smoker, try to smoke as little as possible at the same time as you are feeling unwell. Nasal Decongestants possibly will ease breathing.
