Around 17% of women and 31% of men admit they don’t wash their hands regularly after using the toilet. Germs from raw food can cause sickness, diarrhoea and fever. An American study found that when tested only 6% of bank notes were germ-free. The rest carried bugs including those that can cause pneumonia. There can be about a gram of poo in a pair of dirty pants! Bacteria are too small to be seen without a microscope. Most are about 1/1000th of a millimetre, which is very tiny! A typical bacteria can divide every 20 minutes. Bacteria from a sneeze can be passed from person to person in the air, by touch or by surface contact. Germs When were you last unwell? How did you feel? How do you think you became unwell? Bacteria and Virus Bacteria Virus A bacteria is a simple microbe made of just one cell. Viruses are the smallest of all microbes. Many bacteria have a long spinning tail that helps them move. Viruses need a living host cell to allow them to reproduce and survive. Bacteria can cause illnesses such as sore throats, whooping cough and food poisoning. Viruses can cause illnesses such as chickenpox, cold sores and the flu.
