Across
- 5. are tiny, single-celled organisms that can be found everywhere, including on your skin, in the air, and in your body.
- 7. is when harmful germs like viruses, bacteria, or parasites enter the body and start to grow, often causing sickness or disease.
- 11. is the body's first line of defense against germs. It includes things like skin, saliva, and white blood cells that quickly fight off infections without needing to recognize the specific germ.
- 13. is an outbreak of a disease that spreads rapidly and affects a large number of people within a specific area or population. It is usually more limited in scope compared to a pandemic
- 14. is the body's ability to remember germs after an infection or vaccination. This helps the immune system respond faster and stronger if the same germ attacks again.
- 17. an organism—typically an arthropod, such as a mosquito, tick, or flea—that transmits pathogens (like viruses, bacteria, or parasites) from one host to anotherp
- 18. infectious disease is the germ (such as a virus, bacteria, fungus, parasite, or prion) that causes illness in a person or animal.
- 19. is a tiny germ that can only reproduce inside the cells of a living organism.
Down
- 1. is when the body produces its own protection (antibodies) against a disease after being exposed to the germ or through vaccination. It usually lasts a long time, sometimes for life.
- 2. an infectious disease is the effort to prevent and control the spread of diseases in communities. It includes vaccination, sanitation, education, and disease monitoring to keep people healthy.
- 3. is when a person gets antibodies from another source, like a mother passing them to her baby or through antibody treatments. This protection is immediate but only lasts a short time.
- 4. is the body's defense system that learns to recognize and fight specific germs. It takes longer to develop but provides stronger protection and memory against future infections from the same germ.
- 6. infectious disease refers to how germs (like viruses, bacteria, or parasites) spread from one person, animal, or surface to another. It can happen through direct contact, the air, contaminated food or water, or insect bites.
- 7. is how the body defends itself against germs like viruses and bacteria. It includes making antibodies and activating cells to fight infections and keep you healthy.
- 8. is a type of white blood cell that plays a key role in the immune system. B-cells produce antibodies, which are proteins that help fight infections by recognizing and binding to harmful germs like viruses or bacteria. They are part of the adaptive immune response and help protect the body from future infections.

- 10. is an outbreak of a disease that spreads across countries or continents, affecting a large number of people.
- 12. is a type of white blood cell that plays a key role in the immune system. It helps protect the body by recognizing and attacking infected cells or cancer cells
- 15. in infectious disease is any place where germs (like bacteria, viruses, or parasites) live, grow, and reproduce. It can be humans, animals, or the environment (such as water or soil). Reservoirs are important because they help spread the germs to new hosts.
- 16. is when a person gets a vaccine to help their body build protection against a disease. Vaccines train the immune system to fight germs without making the person sick.
