Germs are found just about everywhere you could possibly imagine including surfaces, the air, soil and water, and in our own bodies. Many of these germs are actually helpful. They provide nutrients, work to decompose trash, and assist in breaking down food in our bodies. Some however are not so good, and these unfortunately give all germs a pretty bad rep. Keep reading to learn about the three major types of germs and how to stay safe from the bad ones.


Because viruses are not considered living, they need a home in living cells to grow and reproduce. To do this, they invade a ‘host,’ which can be anything living including animals, plants, and us! In this process, the host cells are slowly destroyed. This process leads to serious diseases such as influenza (the flu) and rhinovirus.


Unlike viruses, bacteria are able to live just about anywhere you can imagine. For the most part, bacterium helps us in our daily lives, however they can be just as dangerous as viruses. They reproduce inside the human body and can cause infections like pneumonia. They can also live in food, which causes the spread of E. Coli and is the primary reason properly cooking food is so important.


Like bacteria, fungi can be very helpful and includes yeasts, mushrooms and less pleasant, mold. Because they don’t have mouths, some will absorb the nutrients they need through living organisms. This process can cause diseases such as Athlete’s Foot and Ringworm.

Most viruses, bacteria, and fungi are spread through breathing, coughing, and sneezing. We can also pickup the bad germs through infected objects such as doorknobs, surfaces, or shaking the hand of someone already infected.

Now that you know more about what germs are and what they do, how do you stop the bad ones? Luckily, the easiest way is through the simple good practices we all learned growing up. Washing hands throughout the day, using disinfectants to kill 99.9% of germs on surfaces, and getting regular immunizations can all dramatically decrease the chances of harmful infection.
