Over 30 children younger than three years of age developed gastroenteritis after visiting a local water park. These cases repres

ented 44% of the park visitors in this age group on the day in question. No older individuals were affected. The causative agent was determined to be a member of the bacterial genus Shigella. The disease resulted from oral transmission to the children. Based only on the information given, can you classify this outbreak as an epidemic? Why or why not? If you were an epidemiologist, how would you go about determining which pools in the water park were contaminated?

Answer:

No this is not an outbreak

Explanation:

No it cannot be classified as outbreak because an outbreak is when the number of affected individuals in an epidemic is much higher as compared to the estimated values. However, an epidemic is the one that affects the people around different countries of the globe.

This can be considered as endemic that is restricted to a certain set of people in a community

I would have studied pattern of movement of affected kids. The common pool to which all these kids visited can be the infectious one. Also one can test the pathogen in infected kinds, and look for similar pathogen in pool water through testing.

8. What can be concluded from the evidence that coughs and sneezes are natural
andreyandreev [35.5K]

Answer and explanation:

8. <u>What can be concluded from the evidence that coughs and sneezes are natural  reflexes and from the evidence that our immune system attacks allergens? </u>

Coughing and sneezing are natural defense mechanisms that consist of the sudden expulsion of air from the respiratory tract, with the intention of expelling any substance harmful to the body.

Allergies are the product of an exaggerated response of the body to the presence of environmental substances, such as dust, fungi and pollen, called allergens. This abnormal response is caused by an immune system previously sensitized to these substances.

Under normal conditions, the immune system is designed to defend an individual against potentially harmful elements. Coughs and sneezes are natural defense mechanisms, which are exaggerated in allergy sufferers.

9. <u>What two possible reasons for the increase in allergies are explained in the passage? </u>

<em>- "Some scientists think our immune systems don't have enough to do ..." "... when our immune system have fewer germs to fight, they can get confused". </em>

According to the excerpt, an immune system that has been inactive due to less contact with germs, looks for a way to attack any substance foreign to the body, which would be a mechanism that promotes the presence of the allergic response.

The confusion of the immune system would be given in some people by reacting in an unusual way to environmental stimuli or food, which do not affect the majority of people.

<em>- ... "weather is warmer for longer periods now, so plants bloom longer .. release pollen, which is a common allergen". </em>

Plant pollen is considered an aeroallergen capable of producing the response with sneezing or coughing in sensitive people.

Other evidence implies an increase in the amount of aeroallergens, as a consequence of the temperature change. A warm temperature for long periods of time promotes flowering in plants more frequently, and there is more pollen dispersed in the environment.

10. <u>What can be concluded about the increase of allergies in the future?</u>

In the text it can be clearly seen how, according to statistical data, the presence of allergies in more people has increased over time.

Many factors may induce an increase in the number of allergic patients in the future, such as the example provided by the passage of children less exposed to germs due to the use of increasingly available medications.

  • <em>In the past, there were fewer allergies because the immune system remained active to defend the body without the help of drugs.</em>
  • <em>Additionally, the increase in processed food products may be a factor that in the future increases the appearance of allergies in the population. </em>
  • <em>Again, the environmental factor plays a determining role. Over time, many climatic changes occur, which, combined with environmental pollution, may lead to increased allergies in the future.</em>
