Germs are invisible and can be contacted with human touch any time by any medium. People come to the contact of germs without knowing, so it is more dangerous because they do not know what germs will affect them in which way. If any people carrying a germ sneezes or coughs, then the germ spread to the people surrounding him or her. Along with that, people get to the contact of germs by touching something that has germs. Hence, it is important to wash the hands regularly and maintain cleanliness. Regular handwashing stop the infection spread and prevents illness.
