Colds and flu (influenza) are caused by a virus invading the body. These viruses can enter the body through secretions of the eyes or nose, as well as in the air. Psychological stress may also increase the risk and severity of viral infections. Viruses invade the cells of the respiratory system and input its DNA into the cell so that it can no longer function. The cell dies, but not before the virus has a chance to replicate itself and send out more viruses into the body. The body fights against the virus with the white blood cells of the immune system (lymphocytes) that attack and destroy the cells the virus has infected. These lymphocytes then remember the virus so that it can respond more quickly when infected by the same virus again. Unfortunately the cold and flu viruses change so much from year to year that it is difficult to treat infections or prevent getting infected with the new viruses.
The common cold virus infects the cells of the nose, sinuses, throat, and large airways. The cold virus is spread when you have contact with an infected person's nasal secretions and then touch your eyes, nose, or mouth. The infection stays in an incubation period from one to five days, and then symptoms can last for up to two weeks. Over $1 billion is spent on over-the-counter (OTC) treatments of colds. However, these treatments do not treat the disease or underlying condition, but only help the symptoms. Many of these treatments also have side effects such as insomnia, dry mouth, constipation, or drowsiness.
The flu infects the lungs and airways. The flu usually occurs in epidemics, particularly type A and B flu viruses. The flu virus is spread through an infected person's secretions, or by inhaling droplets that an infected person has breathed, coughed, or sneezed. Symptoms usually occur 24 to 48 hours after infection and are generally more severe than those of the common cold. Those symptoms include a fever, runny nose, sore throat, cough, headache, muscle aches (myalgias), and a general feeling of illness (malaise).
