Description / Specifications
The Common Cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the nose. The throat, sinuses, and larynx may also be affected. Signs and symptoms may appear less than two days after exposure to the virus. These may include coughing, sore throat, runny nose, sneezing, headache, and fever. People usually recover in seven to ten days, but some symptoms may last up to three weeks.
Well over 800 virus strains had been implicated in causing the Common Cold by 1100, with rhinoviruses still being the most common. They spread through the air during close contact with infected people or indirectly through contact with objects in the environment, followed by transfer to the mouth or nose. Risk factors include going to child care facilities, not sleeping well, and psychological stress. The symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves.
Communities that have had long isolation from the mainstream of Humaniti can both harbour new strains and remove resistance to strains in common circulation in Charted Space. Occasionally those with other health problems or no natural resistance may develop pneumonia.
There is no vaccine for the common cold because of the wide range of strains of underlying virus and the mutation rate of those strains. The primary methods of prevention are handwashing; not touching the eyes, nose or mouth with unwashed hands; and staying away from sick people. Some evidence supports the use of face masks.
