In 2020, there were 331 million people in the United States. Of these people, 37,800,000 had  COVID-19.Total deaths in 2020 numbered 3.4 million, of which 377,000 were due to COVID-19.   Calculate and interpret in words the all-cause mortality rate in 2020 per 10,000 Round to the nearest whole number.   Calculate and interpret in words the COVID-19-specific mortality rate in 2020 per 10,000  Round to the nearest whole number.   Calculate and interpret in words the 1-year case-fatality rate of COVID-19. For this question, assume thepeople who died of COVID-19 were newly diagnosed in 2020 and died within a A case-fatality rate  should be expressed as a percentage. Round to the nearest tenth.   Calculate and interpret in words the proportionate mortality ratio of COVID-19 in 2020. A PMR should be expressed as a Round to the nearest whole number.

Use your knowledge of population growth models to evaluate the spread of Covid-19 in the world population. How would you characterize this type of growth? Consider growth the increase/decrease in the number of cases per a certain amount of time (day or week).

Does this epidemic curve suggest a point source or propagated epidemic? Justify your answer. What does the "moving averages" (black line) represent? bruefly explain this term in relation to the concept of "variability"?

Panthers are also susceptible to a respiratory infection [feline calicivirus].  Individuals in a population, who are homozygous dominant or heterozygous for genes encoding parasite or pathogen resistance, are more likely to resist an infection or parasite.  Currently, population estimates of the Florida panther range from 100 – 160 individuals.  Let’s assume that the population equals 160.  During a particularly bad calicivirus outbreak,   40 Florida panthers die as a result of the infection.  Using this information, answer the following questions utilizing the Hardy – Weinberg equation when necessary.     What is the most likely genotype of the affected panthers that died from the respiratory infection? Use the letter “A” for your symbol.         2. What percentage of the population is most likely resistant to the calicivirus infection?

For a particular disease or health condition of interest in a specific population, which of the following can be expected to have the smallest numerator?   a. Lifetime prevalence of the disease or health condition in this population on Sep 01, 2022   b. Period prevalence of the disease or health condition in this population since Jan 01, 2022 through Sep 01, 2022   c. Point prevalence of the disease or health condition in this population on Sep 01, 2022   d. More information will be needed to answer this

How do I calculate the ST50 from my raw data to give me time at which 50% sedation has occurred graphically of all of my replicates? Using excel do I use linear graphs? scatterplot? what kind of trendline? with what setting? Raw data includes time from 0-24 hours + # of flies sedated at different intervals. En

In this fictitious example of a cohort study, we found that in a factory of 3,000 workers, 1,000 workers were exposed to toxic substances, and 2,000 were not. During the study period, 800 of the exposed workers developed some type of lung disease, and only 40 of the non-exposed workers developed a lung disease. A. What is the incidence of lung disease among exposed workers? Use 1,000 as the multiplication factor and answer should be in whole numbers. B. What is the incidence of lung disease among non-exposed workers? Use 1,000 as the multiplication factor and answer should be in whole numbers.

this is the survival curve of the data below, can you explain what does the straight line mean? is it necessary to have that? where do you know where to put the straight line? day animal survivors 0 50 2 44 4 42 7 41 9 40 11 39 14 39 16 39 18 39 21 39

Vaccinating 65% of a population will provide herd immunity for a disease with which of the following reproductive rates?  Pc= 1-(1/R0) Group of answer choices 2.2 Herd immunity will not be achieved for any of these reproductive rates. 4.5 3.1 5.0 Herd immunity will be achieved for all of these reproductive rates.
