Cold Viruses
The common cold (alsoknown as nasopharyngitis, rhinopharyngitis, acute coryza, or a cold) is a viral infectious disease of the upper respiratory tract which affects primarily the nose. Symptoms include a cough, sore throat,runny nose, and fever which usually resolve in seven to ten days, with some symptoms lasting up to three weeks. Well over 200 viruses are implicated in the cause of the common cold; the rhinovirusesare the most common.
No cure for the common cold exists
The typical symptoms of a cold include cough, runny nose, nasal congestion and a sore throat, sometimes accompanied by muscle ache,fatigue, headache, and loss of appetite.
Physical measures to prevent the spread of cold viruses have been deemed the only potentially effective measures for prevention. These measures include primarilyhand washing and face masks; in the health care environment, gowns and disposable gloves are also used. Efforts such as quarantine are not possible as the disease is so widespread and symptoms arenon-specific.
Influenza
Influenza, commonly known as the flu, is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses. The mostcommon symptoms are chills, fever, sore throat, muscle pains, headache (often severe), coughing, weakness/fatigue and general discomfort.
Vaccination against influenza with an influenza vaccine isoften recommended for high-risk groups, such as children and the elderly, or in people who have asthma, diabetes, heart disease, or are immuno-compromised. Influenza vaccines can be produced in severalways; the most common method is to grow the virus in fertilized hen eggs. After purification, the virus is inactivated (for example, by treatment with detergent) to produce an inactivated-virus...
