There is no firm evidence that Echinacea products or garlic provide any meaningful benefit in treating or preventing colds. Vitamins C and D
Vitamin C supplementation does not affect the incidence of the common cold, but may reduce its duration. There is no conclusive evidence that vitamin D supplementation is efficacious in the prevention or treatment of respiratory tract infections. Prognosis
The common cold is generally mild and self-limiting with most symptoms generally improving in a week. In children, half of cases go away in 10 days and 90% in 15 days. Severe complications, if they occur, are usually in the very old, the very young, or those who are immunosuppressed. Secondary bacterial infections may occur resulting in sinusitis, pharyngitis, or an ear infection. It is estimated that sinusitis occurs in 8% and ear infection in 30% of cases. Epidemiology
The common cold is the most common human disease and affects people all over the globe. Adults typically have two to three infections annually, and children may have six to ten colds a year (and up to twelve colds a year for school children). Rates of symptomatic infections increase in the elderly due to declining immunity.Native Americans and Inuit are more likely to be infected with colds and develop complications such as otitis media than Caucasians. This may be explained as much by issues such as poverty and overcrowding as by ethnicity. History
While the cause of the common cold was identified in the 1950s, the disease appears to have been with humanity since its early history.
"; a proper response should be "Ďakujem" which means "Thanks". This is also the case in Finland where "terveydeksi" means "for health". Likewise in Russian or Ukrainian, "будь здоров" (bud zdorov), translates as "be healthy". In Tamil, a reciprocation to someones sneeze is "ஆயுசு நூறு" (aa-yu-su noo-ru) or "ஆயுள் நூறு" (aa-yul noo-ru) which, in direct translation, means "100 years-long life". It is a particularly endearing expression often used by elderly when a young child sneezes, wishing upon them good health, as a sort of blessing. Some may say "Dheergaiyish", meaning "may you live long", but that is more closely related to Sanskrit. In Turkey, after a person sneezes, it is proper to say "Çok yaşa" which means "Live long"; a proper response should be "Sen de gör" which means "May you see too [that I lived long enough]". In Telugu, a reciprocation to someones sneeze is "chiranjeeva sataish" (చిర౦జీవ) which means "may you live long" (from Sanskrit). In Japanese and Chinese entertainment, such as anime or dramas, a characters sneeze usually means that someone is talking about the character. In the Netherlands and Flanders, the usual verbal response is "Gezondheid!" which has the same meaning as the also occasionally used German word "Gesundheit!". This is usually met with a "Dankjewel" as a response, which means "Thank you". In Sweden, Norway and Denmark after a person sneezes, it is proper to say "Prosit", which has latin roots, and loosely translates to "Be well" or "May it do you good".
