Symptoms
As i said before the symptoms of this disease is sore throat, runny nose and fever sometimes accompanied with pink eye, muscle aches, tiredness, headaches, shivering and lost of appetite. these symptoms will last up to 7 to ten days but it can last for 3 weeks too. 30% - 40% of children cough lasts more than 10 days, 10% of children continue for more than 25 days. How can it spread? The common cold is usually spread by touching infected surfaces and by direct hand to hand contact from an infected individual. For example if a person with the cold blew or touched their nose then touched someone else, that person can be eventually become infected with the virus. Also, a cold virus can live on top of objects such as key boards, cups, tables, television remotes for a few hours, and can thus be acquired from contact with these objects.external image Handshake%20hurts%20hand%20shake%20painful%20pain%20bad.GIF Does the cold have anything to do with exposure with cold weather?? The common cold usually occurs at fall and winter. The cold weather itself doesn't cause the cold. Rather, it is thought that people spend more time indoors in close proximity to each other. Thus speeding up the spread of the virus. For this same reason, children in day care and school are more easy to have the common cold.external image Classroom%20group.JPG What is the difference between the common cold and the influenza (flu)?Many people confuse the common cold with the flu. influenza is caused by the influenza virus and the common cold is not. while the symptoms of the cold and the influenza are similar, patients with the common cold typically have a milder illness. While the people with influenza are usually sicker and have a more rapid onset with fever, chills, headaches, body aches, dry cough and extreme weakness.
ConclusionEven tho the common cold is not very harmful and do not affect much but you should keep your hands clean, if you got the cold just keep clean and stay home just in case you spread it to anyone. If your in the fell or winter just remember to keep clean and wash your hands frequently with soap.
