Please answer the following questions, 15 sentences minimum per number. 1 – Provide a brief summary (5 sentences) about all the ways the human body responds to infection of an invading pathogen. Then describe the biology of the 1918 flu, given this information: The 1918 flu was particularly dangerous to people of younger age, unlike most flus which generally kill the very old, the very young, and pregnant women. This flu works by what is known as a “cytokine storm”. How did the CDC recover the 1918 flu in order to study it and how it works? How does a “cytokine storm” work to kill people? Why would this kill people in their 20’s and 30’s more than the very young or the very old? This answer should be AT MINIMUM 15 sentences long. Cite your sources. 2 – The CDC contains information on diseases including epidemiological data such as prevalence, incidence, and mortality rate of the disease. Define each of these terms and explain why it may be important to know about each of these data points. Then, look up the prevalence, incidence, and mortality rates of hanta virus, the flu, and HIV/AIDS in the United States. Then compare these data points between these diseases and explain what this means (Which one is scarier? Which one takes more lives? Which one would you more likely die from?). This answer should be AT MINIMUM 15 sentences long. Cite your sources. 5.5.5 – There is a really interesting history regarding smallpox, bubonic plague, and HIV. Some people are resistant to HIV, and these individuals are more often Caucasian than of any other ethnicity. It may be because Caucasians were killed more than any other ethnicity by smallpox and the bubonic plague. What is this evolutionary connection? What is evidence for this connection? Which disease do you think contributed to HIV resistance in Caucasian populations today? This answer should be AT MINIMUM 15 sentences long. Cite your sources.
