### Re: Disease Detectives B/C

In June of 2015, there were an outbreak of 87 cases of MERS in the Samsung Medical Centre Hospital in Seoul, South Korea. The first confirmed case of MERS was Oh Sang Eun, a 35-year-old man who had just gotten back from Saudi Arabia a week earlier. 11 cases were in contact with Oh Sang Eun, and another 43 cases had been to the Arabian peninsula within 2 weeks or directly contacted someone who was exposed to MERS. Another 252 patients in the same hospital did not exhibit symptoms of MERS. The WHO traced the people these MERS patients had contacted in the past 2 weeks and 78 did not have the disease.

1. What type of study would be the most relevant for this information?
2. What type of calculation would be most relevant for this type of study?
3. Perform and intepret this calculation.
-
1. This would be a (retrospective) case-control study. The population of susceptible people is not well-defined.
2. An odds ratio would be used here.
3. a = 11 + 43 = 54 b = 78 c = 87 - a = 87 - 54 = 33 d = 252
a = 54  b = 78  c = 33  d = 252
$OR = \frac{ad}{bc} = \frac{54*252}{78*33} = 5.29$

Here's a shorter question.

What diseases do Anopheles mosquitos transmit? What about Aedes mosquitos?
So much to do, so little time.

### Re: Disease Detectives B/C

Disease detectives often do several parts of an outbreak investigation at the same time.

Which of the following steps are they likely to do simultaneously?

A. Publish results of the study.
B. Interview new cases.
C. Conduct the environmental study.
D. Research similar outbreaks.
E. Identify new cases.
F. Plan the study design.

D. Research similar outbreaks. & F. Plan the study design.
General Order:
[list=1][*]Identify new cases.
[*]Research similar outbreaks.
[*]Plan the study design.
[*]Interview new cases.
[*]Conduct the environmental study.
[*]Publish results of the study.[/list]
I've probably messed up somewhere here.

B, C, D, and E can all be done at the same time.
Looking back at it, I'm not sure this was a particularly good question . Your turn.

Eh. I generally mess up on ordering stuff.

What's the difference between the three main types of influenza viruses?

What's the difference between the three main types of influenza viruses?
Influenza A: categorized into subtypes, which are based off of the variations in the virus's surface proteins (hemagglutinin and neuraminidase) and into lineages; is usually the virus behind the "flu season" and has caused pandemics
Influenza B: categorized into lineages and strains, causes symptoms similar to those of Influenza A
Influenza C: causes the mildest symptoms, are not thought to have caused any pandemics
