With the view to ensure the sanitary and epidemiological wellbeing of the people and to prevent mass outbreaks of infectious diseases, the World Health Organisation strongly recommends maintaining good hand hygiene, because the untidiness can have dire consequences for health. Just imagine: if you do not wash your hands before eating, then the pathogens of the most dangerous diseases – viral pneumonia, ARVI, influenza and hepatitis – can easily get into the body.
