- What patterns do you detect? Often in disease outbreak investigations we want to see a pattern for a particular problem. Think back to the 'white board' approach from a previous question and consider the types of information about individuals that may help you look for patterns. Select from the list below attributes that may help you You can chosse all or some I choose Time of disease onset and occuption but there is more I guess Occupation Hair color Gender Weight Age Time of disease onsetAnswer each question by itself 1. What are the top 5 causes of death in the United States for 2020? 2. How have these changed over the past 10 years? 3. Which of the top 5 causes of death can be attributable to communicable disease, non-communicable disease, and/or environmental diseases and injury? Do they have multiple causes? 4. Relating the top causes of mortality to "actual" causes of death (Table SO3.2), what cause would your group decided to focus public health initiatives to reduce mortality in America today? Why? Table is found on page 127 of your text in Section III. https://www.cdc.gov/nchs/fastats/leading-causes-of-death.htm I need questions 2-4. I already have question 1As a municipal fisheries officer (MFO) you were assigned to investigate a report on the occurrence of poor breeding activities of freshwater tilapia in a barangay involved in tilapia aquaculture. It was also reported that the fry produced is weak and is always affected by fungal and bacterial infection. You have ordered a blood and tissue analysis of the fry and the broodstock and the results are: Prostaglandin in the blood of broodstock is low as compared to normal values. Eicosanoid levels in the larvae were below the normal levels. With these results, what major dietary nutrients would you order to be analyzed? What major nutrients would you suspect are inadequate and are causing these problems. (Bear in mind that this is a freshwater fish.) Discuss what is the role of/these nutrients in Fish breeding and immune responses.

Table is found on page 127 of your text in Section III. https://www.cdc.gov/nchs/fastats/leading-causes-of-death.htmQuestions 61 - 63 are based on the following information. The following equation is an epidemiological model for diseases such as measles or flu describing the factors that are expected to affect disease spread rate (R.) in a population: Ro = BS/y B = the infection rate (describes how infectious a disease is); y = the recovery rate (describes how fast can an infected person recover); S = Population density of susceptibles (suscptibles are individuals without immunity to the specific pathogen) 61. What type of a model is this? a. Verbal b. Mathematical C. Statistical d. Simulation 62. According to this model, what is the effect of Population density of susceptibles on disease spread rate? Disease spread rate increases with increasing density Disease spread rate decreases with increasing density Disease spread rate is not affected by increasing density Impossible to know а. b. c. d. 63.
