List which of Hill's criteria each of the following is an example of.

1. The more a person smokes, the higher likelihood of developing COPD.

2. In a hypothetical study on COPD, it is observed that those studied that have never smoked don't develop COPD, whereas those who smoke the most often develop COPD.

3. An outbreak of Legionnaire's disease may be caused by visiting a hot tub, because that is a common mode of transmission for Legionella spp.

Match each of the following statements to the correct type of surveillance.
a. Diseases are reported to health care providers regularly.
b. Health agencies contact health providers seeking reports. 
c. Focuses on symptoms rather than laboratory confirmed disease.

Four types: Active, Passive, Sentinel, Syndromic

a. Passive? (Do you mean reported [i]by[/i] health care providers?)
b. Active (I'm assuming you mean the health agencies are the ones seeking reports
c. Syndromic?
d. Syndromic
e. Active

100 Science Olympiad teammates hold a party at 3AM after a tournament.
They sneak several food items from various sketchy locations. Some people focus on consuming various food items, some test their manipulation capabilities in mafia, and some watch Bird Box.

A day or so later, 50 of the teammates report symptoms of a gastrointestinal illness. Tests from the biotechnology lab at their high school reveal the agent to be a bacterium known as H. jerrah (Havishus jerrah).
Attached is a contingency table: https://drive.google.com/open?id=1Dy2zQ ... I2Fi84cmXO

1. a) Calculate the Odds Ratios for each exposure. Give your answers to two decimal places.
b) What is the most likely cause of the outbreak?

2. a) What is notable about the OR for playing mafia?
b) What kind of factor is playing mafia?
c) Propose an explanation for this.

3. a) Given that watching Bird Box induces people to stress eat a specific food, which food is it?
b) Justify your answer.

Note: Some values may be slightly unrealistic.
