Sterilisation is the process of removing all traces of bacteria and other germs. It is an important process, which helps to reduce the risk of infection and prevent the spread of infections and illnesses.
According to World Health Organisation, available at http://www.who.int/en/, sterilisation is used in a variety of different clinical settings, including hospitals, dental surgeries and community health centres, as well as at home, beauty salons and in outlets or places providing food.
During their first year of life, babies are at their most vulnerable to viruses, bacteria and parasitic infections, which can lead to anything from a mild attack of thrush to the more serious condition of gastroenteritis. This is an illness similar to food poisoning, which can cause vomiting, and subsequent dehydration. Stephanie Brown in her recent article on Toddlers and Twos (you can read a full article here: http://babyparenting.about.com/od/nutritionandfeeding/f/sterilizebottle.htm) argues that before sterilization was the norm, thousands of infant deaths were caused by this condition.
According to many hygiene specialists, check http://www.gloveclub.co.uk/ for example, sterilisation is very important in the medical industry. Without sterilisation, infections would fly around and thousands of lives would be lost. Sterilisation helps to prevent the development and spread of infection, as well as protecting members of staff working in clinical settings and members of the public.
In the beauty salon, sterilisation is not really necessary, this process is only required on instruments entering the body cavity. This procedure is normally used in the medical and dental field. Some salons, however, do use heat to sterilize metal instruments in order to prevent viruses, and diseases.
