Colds affect all of us, usually once or twice a year (more often for those with weaker immune systems) and leave us sneezing and coughing. Typically, the common cold also causes a runny or blocked nose, a sore throat, aching muscles and a general feeling of unwellness.Contrary to popular belief though, there isn’t actually a cure for a cold. It’s caused by a virus, which is spread from person to person through touching contaminated surfaces or through airborne droplets from coughs and sneezes. Colds can be highly infectious, and you often find that entire households or office blocks pass the illness between them.The fact that it’s a virus means that antibiotics are ineffective, and it’s actually dangerous to take them when you don’t need them, as they could cease to work in the future. There is no miracle fix unfortunately, you simply have to wait for the illness to run its course.
