4. What are some advantages to the technology related to infectious disease that was developed in the 20th century? (NOTE: Please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.) Ability to design drugs that target molecular pathways in infectious agents Eliminate the mechanisms involved in most microbial drug resistance Determine the causative agents of new or unknown diseases Develop vaccines against the major infectious disease agents that cause death worldwide Ability to detect infectious diseases that were previously difficult to diagnose Ability to produce mass quantities of effective viral vaccines

Many of us have been impacted by outbreaks of disease in our lifetimes. Throughout history, humans have battled outbreaks of disease; many have lost their lives to diseases before treatments and cures were discovered. Modern science and medicine have become efficient in developing vaccines and medications to control and treat outbreaks, but whether the diseases will ever truly be eradicated is in question. Considering how many of these infectious diseases exist and how easily they spread, it is important to remember safety issues to reduce and prevent transmission. Reflect over the past decade and recall a news-breaking infectious outbreak of a disease that made an impact on you. Please include a link to a news article or video related to your outbreak. Include... - Disease name - Infectious agent (is the disease bacterial, viral, or fungal? List the specific organism (genus species)) - Mode of transmission - Signs and symptoms of the disease - Treatment (or treatments) available - Explain how that story changed the way you interacted with people, family, or friends.

1. These vaccines contain a version of the live virus or bacteria that has been weakened so that it does not cause serious disease in people with healthy immune systems. - live, attenuated vaccine - subunit vaccine - conjugate vaccines - inactivated vaccine 2. These types of vaccines target bacteria with polysaccharide coatings and are effective for these types of bacteria because they connect the polysaccharides to antigens that the immune system responds to very well. - conjugate vaccine - subunit vaccine - inactivated vaccine 3. Some researchers are working on developing a vaccine for COVID-19 that would put virus-like particles, such as empty virus shells that mimic the virus structure, into the human body. These are an example of what type of vaccine? - nucleic acid vaccines - virus vaccines - viral vector vaccines - protein-based vaccines - toxoid vaccine 4. Some researchers are working on developing a vaccine for COVID-19 that would use genetic instructions (in the form of DNA or RNA) for a coronavirus protein that prompts an immune response. These are an example of what type of vaccine? - protein-based vaccine - viral-vector vaccine - nucleic acid vaccine - virus vaccine

Outbreaks of viral disease are a continuing threat in the United States as well as abroad. The Centers for Disease control and other international agencies devote considerable resources to surveillance and detection programs as well as advancement of communicable disease prevention and mitigation measures. Preventing outbreaks is the ultimate goal, but establishing protocols that ensure preparedness in the event of an outbreak is also important. For this discussion you have an opportunity to characterize key features of a virus with epidemic or even pandemic potential and chose one disease you feel would be best suited for significant research and pre-emptive efforts. Keep the following questions on hand as you view the video. What are the attributes of a particularly dangerous emerging infectious disease? What features of modern society influence dissemination of viral diseases of this nature? Using the information you learned from the readings and videos you have reviewed this week to support your answers, address these questions in your discussion post. If you were in charge of distributing one-hundred million dollars in research funds but could only chose one viral disease to provide for, which disease would you endow and why? How do you think the medical and scientific community should use your millions?
