An outbreak in which the epi-curve that clearly shows more than one peak in cases over time is most likely what kind of epidemic:
A point source
A common source
Propagated with secondary cases
Propagated with overlapping secondary cases
Ans
Multiple peak show propagated epidemic
And it lead to secondary case
So it is propagated with overlapped secondary cases
An outbreak in which the epi-curve that clearly shows more than one peak in cases over...
An epidemic curve that shows an initial steep increase in the incidence rate followed by a more gradual decline is characteristic of a: Point source epidemic Propagated epidemic Flu epidemic Sporadic epidemic
1) The epidemic curve for both the Hepatitis Outbreak and Oswego Outbreak case studies are indicative of this type of outbreak. A) propagated (progressive source) B) continuous common source C) point source D) confirmed 2) What is the term used to describe; "The severity of the disease; measured by the case fatality ratio (CFR%)". 3) If a male participant in an HIV study considers himself heterosexual, yet has a history of sex with men, he may not reveal the homosexual...
Discussion #5: 1. In terms of epidemic patterns: 1) point source, 2) intermittent or continuous, and 3) propagated. For each of the following outbreak settings, choose the most likely epidemic pattern and explain your answer. A. Outbreak of salmonellosis traced to turkey cooked and held at an improper temperature and served at a pot-luck supper. B. Outbreak of influenza among nursing home residents, new cases occurring over a 3-week period (Hint: incubation period for influenza is less than 5days.) C....
Which of the following is not a reasonable definition for an outbreak? Select one: a. Identified cases of coronavirus due to a novel strain not previously detected in humans b. Two or more persons experiencing a similar illness after ingestion of a common food OR different food in a common place. c. A large number of cases occurring in a geographic region or jurisdiction (i.e. cases are well above baseline for jurisdiction for a specific time period) d. Incidence >10...
Please perform calculations and respond to the following questions. Question 1: One hundred and eight (108) cases of staphylococcal food poisoning were reported in a rural community in August 1989. Incubation period was 2-6 hours. First case occurred at 8:00 p.m., August 6 and last case occurred at 4:00 a.m., August 7, 1989. Peak of cases was at 10:00 p.m. Based on the information provided above, what was the most likely period of exposure to the source of epidemic among...

Please answer the polymers questions below clearly. 1. Discuss (no more than one page) the dif- ference in the nature of the glass transition and the crystalline melting point. 2. Explain (no more than one page) why polymers crystallize in a folded chain form. (A picture is worth a thousand words!) 3. In Figure 10-50 in the text, the chain struc- tures of isotactic polystyrene and isotactic polypropylene were compared. We then asked you which of these polymers has the...
