What are germs?
We use the term ‘Germs’ or ‘Pathogens’ to describe a variety of micro-organisms that can make people ill, these can be bacteria, viruses and fungi (mould). These tiny bugs can cause a range of illnesses, from the common cold to more serious, life threatening conditions.
When germs invade our bodies, they use up nutrients and energy. Toxins (poisons) are produced which cause the symptoms of illness - like fevers, coughs, sniffles, rashes, vomiting and diarrhoea. In the case of viruses, they actually invade individual cells and destroy them.
Bacteria
Bacteria are small simple organisms that exist everywhere around us, and can reproduce very quickly. They thrive in damp dirty environments and decaying matter.
Viruses
Viruses are far smaller than bacteria and are not ‘active’ on their own. They can lie dormant on surfaces, but need to infect a ‘host’ cell in order to reproduce.
Fungi
Fungi are moulds and yeasts that are common all around us, such as mildew. They can produce spores which, when inhaled, can cause respiratory problems and allergic reactions.
