Health Consequences of Bacteria and Viruses

Have you ever wondered why you get sick with a fever, cough, or stomach ache? Many illnesses are caused by tiny organisms called bacteria and viruses that can enter the body. With this worksheet, you explore how these microbes affect your health and how your body responds. Each activity helps you understand what happens inside your body during an infection. As you learn, you become more aware of how to protect yourself and others.

Your journey begins by learning the difference between bacteria and viruses. Bacteria are living organisms that can survive on their own, while viruses need a host to multiply. You explore how some bacteria are helpful, but others can cause disease. Activities guide you to identify common illnesses caused by each type. This helps you build a clear foundation of health knowledge.

Next, you explore how bacteria and viruses spread from person to person. Sneezing, coughing, touching surfaces, and sharing food can all pass germs along. Through examples, you learn why washing hands and covering your mouth are so important. Each task encourages you to think about everyday habits that affect health. This strengthens your ability to make responsible choices.
