Question

question 4 (mandatory) (10 points) the public health department nurses are concerned the community is experiencing an outbreak of cryptosporidium. which criteria must be met to define this outbreak as a water - associated disease outbreak? a) two or more people with laboratory - confirmed primary amebic meningoencephalitis b) two or more cases of chemical poisoning if water quality data indicate contamination by the chemical c) two or more people having experienced a similar illness after exposure to water d) epidemiologic evidence implicating drinking water as the probable source of the illness

Explanation:

To define an outbreak as water - associated, there should be a link between the illness and water exposure. Option A refers to a different disease (primary amebic meningoencephalitis). Option B is about chemical poisoning rather than a disease outbreak related to the organism Cryptosporidium. Option D requires only epidemiologic evidence about drinking water, which is too narrow. Option C states that two or more people having a similar illness after water exposure is a general criterion for a water - associated disease outbreak.

Answer:

C. Two or more people having experienced a similar illness after exposure to water
