Across
- 5. a change to a virus’s genetic material that occurs when the virus is replicating. The change is passed on to future generations of the virus.
- 6. antibodies, laboratory-produced proteins designed to mimic naturally occurring antibodies that target specific antigens on viruses, bacteria, and cancer cells.
- 8. the curve, refers to the epidemic curve, a statistical chart used to visualize the number of new cases over a given period of time during a disease outbreak.
- 9. syndrome, the constellation of symptoms experienced by COVID-19 long haulers.
- 10. test, a diagnostic test that detects specific proteins on the surface of the virus.
- 13. immunity, herd immunity occurs when enough people become immune to a disease to make its spread unlikely.
- 16. a virus is the smallest of infectious microbes, smaller than bacteria or fungi. A virus consists of a small piece of genetic material (DNA or RNA) surrounded by a protein shell.
- 18. tracing, a process that begins with identifying everyone a person diagnosed with a given illness
- 19. indicates the benefit of a vaccine in the real world.
- 22. infectious viral particles that can float or drift around in the air.
- 26. a disease outbreak in a community or region
- 29. proteins made by the immune system to fight infections.
- 30. distancing, actions taken to stop or slow down the spread of a contagious disease.
- 31. refers to steps taken to limit the impact of an illness.
- 32. period, the period of time between exposure to an infection and when symptoms begin
- 33. spread, is said to have occurred when people have been infected without any knowledge of contact with someone who has the same infection
- 35. a virus containing one or more mutations that make it different from a version of the virus that has been circulating.
Down
- 1. positive test result, a positive test for the virus that causes COVID-19
- 2. the separation of people with a contagious disease from people who are not sick
- 3. an additional dose of COVID-19 vaccine given after protection from the initial vaccine series begins to decline.
- 4. a substance displayed on the surface of a microbe that stimulates the body to produce an immune response.
- 7. people who have not fully recovered from COVID-19 weeks or even months after first experiencing symptoms.
- 11. of concern, SARS-CoV-2 viruses with mutations that make them more likely to spread, evade vaccines, or make people sicker.
- 12. chain reaction (PCR) test, a diagnostic test that detects the presence of the virus's genetic material.
- 14. short for severe acute respiratory syndrome coronavirus 2, SARS-CoV-2 is the official name for the virus responsible for COVID-19.
- 15. short for messenger ribonucleic acid, mRNA is genetic material that contains instructions for making proteins.
- 17. a disease outbreak affecting large populations or a whole region, country, or continent
- 20. positive, a test result that mistakenly indicates you are infected when you are not.
- 21. distancing, refers to actions taken to stop or slow down the spread of a contagious disease.
- 23. a harmless capsule. In a vaccine, a vector may be used to deliver a substance into the body in order to prompt an immune response.
- 24. test, indicates whether you are currently infected with COVID-19.
- 25. partial or complete protection from a specific infection because a person has either had that infection previously or has been vaccinated against it.
- 27. negative, a test result that mistakenly indicates you are not infected when you are.
- 28. indicates the benefit of a vaccine compared to a placebo in the context of a clinical trial.
- 34. vaccines, mRNA vaccines for COVID-19 contain synthetic mRNA.
