One of the most common diseases in children and adults – the common cold is a infectious viral disease affecting the upper respiratory system, usually caused by rhinoviruses and coronaviruses. Transmitted mainly in aerosol form, through coughing and sneezing, the common cold virus has no efficacious remedy or any antiviral drugs approved, thus being combated by conservative and alternative methods such as analgesics, or ginger, garlic and vitamin C supplements. Recently, British scientists made a breakthrough in cancer research, by using a common cold virus (reovirus) to kill cancer cells, opening the door to novel cancer treatments.
