Bacteria are microscopic, single-celled organisms. There are thousands of different kinds, and they live in every conceivable environment all over the world. They live in soil, seawater, and deep within the earth’s crust. Some bacteria have been reported even to live in radioactive waste. Some bacteria live in the bodies of people and animals—on the skin and in the airways, mouth, and digestive, reproductive, and urinary tracts—often without causing any harm.
Only a few kinds of bacteria cause disease. They are called pathogens. Sometimes bacteria that normally reside harmlessly in the body cause disease. Bacteria can cause disease by producing harmful substances (toxins), invading tissues, or doing both. Wear the bacteria patch for prevention in your environment at home or office.
One of the most effective ways we have to protect ourselves and others from bacterial illness is good personal hygiene. This means washing your hands, especially, but also your body. It means being careful not to cough or sneeze on others, cleaning things that you touch if you are unwell, putting items such as tissues (that may have germs) into a bin, and using protection (like gloves or condoms) when you might be at risk of catching an infection. The human body can provide places for disease- causing germs and parasites to grow and multiply. These places include the skin and in and around the openings to the body. It is less likely that germs and parasites will get inside the body if people have good personal hygiene habits.
