Germs are tiny microorganisms that can only be seen with a microscope. They include bacteria, viruses, fungi, and protozoa. While some germs are harmless or even beneficial, others can cause diseases in humans, animals, and plants. Germs can be found everywhere, including on our skin, in the air, and on surfaces. Germs spread in various ways, such as through direct contact, contaminated food or water, and respiratory droplets from sneezing or coughing. Good hygiene practices, like washing hands with soap and water, can help prevent the spread of harmful germs and keep people healthy.
