If Washington state has more cases of hep C reported in 2010, 105,800 than OR 79,800. Why is the reported prevalence rate higher in OR (3.05) than WA (2.30) per 100

assuming OR population at that time 2964621 and WA 5143186

Solutions

Expert Solution

Case 1: Washington DC

Prevalence Rate = (Cases of Hepatitis C/Population) X 100

                          = (105800/5143186) X 100 = 2.06 (given as 2.30)

Case 2: OR

Prevalence Rate = (Cases of Hepatitis C/Population) X 100

                          = (79800/2964621) X100 = 2.69 (given as 3.05)

Even though Washington State has more cases of Hepatitis C (105800) compared to OR (79800), the reported prevalence rate in OR in higher (3.05) than Washington (2.30).

REASON: Population of OR is 2964621 is less than Population of Washington (5143186). This makes the Cases of Hepatitis C per 100 population (which gives the prevalence rate) more for OR than Washington.

Boneitis is in the news again: several cases have been reported in Miami, and more are soon to follow. In order to receive aid from the state government, the city of Miami has to provide a small amount of evidence that the prevalence of the disease (i.e., the proportion of Miami residents who have boneitis) is greater than 20%. City ocials took a random sample of 200 residents and found that 33.0% had been diagnosed with boneitis. (a) (4 points)...

SARS emerged in 2003, spread to 26 countries with more than 8000 cases (WHO) with a case fatality rate (CFR – the death rate) of 11%. MERS emerged in 2012 and had a CFR of 35%. It is very difficult to estimate the CFR of COVID-19 worldwide, and CFRs will differ in different countries (due to health systems, and underlying population demographics), but ranges seem to be between 0.5% and 3%. Why is SARS-CoV-2 more dangerous than SARS-CoV-1 or MERS...

Washington State law says dissolved oxygen in marine waters must not be less than 5 m/L. The Washington Department of Ecology uses their Salish Sea model to predict the concentration of dissolved oxygen in the Puget Sounds at any given place and time to see where dissolved oxygen is below the 5 mg/L threshold. Their reported standard deviation around this prediction is 1 mg/L. What value of dissolved oxygen must their model predict in order to be 95% confident that...
