Today’s update is the quoted first section of Wikipedia’s article on the Common Cold:
Common symptoms are cough, sore throat, runny nose, blocked nose, and sneezing; sometimes accompanied by ‘pink eye’, muscle aches, fatigue, malaise, headaches, muscle weakness, uncontrollable shivering, loss of appetite, and rarely extreme exhaustion. Fever is more commonly a symptom of influenza, another viral upper respiratory tract infection (URTI) whose symptoms broadly overlap with the cold[1] but are more severe.[2] Symptoms may be more severe in infants and young children.
Those suffering from colds often report a sensation of chilliness even though the cold is not generally accompanied by fever, and although chills are generally associated with fever, the sensation may not always be caused by actual fever.[1] In one study, 60% of those suffering from a sore throat and upper respiratory tract infection reported headaches[1], often due to nasal congestion. The symptoms of a cold usually resolve after about one week, but can last up to three weeks.
Complications
The common cold can lead to opportunistic coinfections or superinfections such as acute bronchitis, bronchiolitis, croup, pneumonia, sinusitis, otitis media, or strep throat. People with chronic lung diseases such as asthma and COPD are especially vulnerable. Colds may cause acute exacerbations of asthma, emphysema or chronic bronchitis.[3]
