What are diseases caused by germs?Show answer
Some diseases are caused by tiny germs (such as bacteria and viruses) that spread from person to person, for example coughs and colds. Good hygiene, like washing hands and covering coughs, helps stop these spreading. Other health problems, like heart disease or type 2 diabetes, are linked to lifestyle choices such as poor diet and little exercise, and can often be reduced by healthier habits.
