This is called "droplet spread." This can happen when droplets from a cough or sneeze of an infected person move through the air and are deposited on the mouth or nose of people nearby. Sometimes germs also can be spread when a person touches respiratory droplets from another person on a surface like a desk and then touches his or her own eyes, mouth or nose before washing their hands. We know that some viruses and bacteria can live 2 hours or longer on surfaces life cafeteria tables, doorknobs and desks. How to Stop the Spread of Germs In a nutshell: take care to
Cover your mouth and nose when coughing or sneezing Cough or sneeze into a tissue and then throw it away. Cover your cough or sneeze if you do not have a tissue. Then, clean your hands, and do so every time you cough or sneeze. Reprinted from Centers for Disease Control and Prevention |
| What Are Germs? Actually, germs are tiny organisms, or living things, that can cause disease. Germs are so small and sneaky that they creep into our bodies without being noticed. In fact, germs are so tiny that you need to use a microscope to seem them. When they get into our bodies, we don't know what hit us until we have symptoms that say we've been attacked! What Types of Germs Are There? Germs are found all over the world, in all kinds of places. There are four major types of germs: bacteria, viruses, fungi, and protozoa. They can invade plants, animals, and people. Bacteria are tiny, one cell-creatures that get nutrients from their environment in order to live. In some cases that environment is a human body. Bacteria can reproduce outside of the body or within the body as they cause infections. Some infections bacteria cause include sore throats (tonsillitis or strep throat), ear infections, cavities, and pneumonia. Not all bacteria are bad. Some bacteria are good for our bodies as they help keep things in balance. Good bacteria live in our intestines and help us use the nutrients in the food we eat and make waste from what's left over. We couldn't make the most of a healthy meal without these important helper germs. Some bacteria are also used by scientists in labs to produce medicines and vaccines. Viruses need to be inside living cells to grow and reproduce. Most viruses can't survive very long if they're not inside a living thing like a plant, animal, or person. Whatever a virus lives in is called its host. When viruses get inside people's bodies, they can spread and make people sick. Viruses cause chickenpox, measles, flu, and many other diseases. Because some viruses can live for a while on something like a doorknob or counter top, be sure to wash your hands regularly. Fungi are multi-cell, plant-like organisms. Unlike other plants, fungi cannot make their own food from soil, water, and air. Instead, fungi get their nutrition from plants, people, and animals. They love to live in damp, warm places, and most fungi are not dangerous. An example of something caused by fungi is athlete's foot, that itchy rash that teens and adults sometimes get between their toes. Protozoa are one-cell organisms that love moisture and often spread diseases through water. Some protozoa cause intestinal infections that lead to diarrhea, nausea, and stomach pain. |
