Answer 1

21. d. August 25th

The incubation period is 21 days. Currently, Nedra is in the latent period. So the exposed date is August 25th.

22. e. After October 31st.

the average communicability period is 6 weeks. So she can go to grocery store after 31st October to prevent the spread of disease conditions.

23.Cluster Vs outbreak

A cluster is a group of diseases in a specific time and causes an outbreak of disease. Dr.Gieseker wants to know whether all cases are specific to particular disease conditions.

24. A broad case definition will produce smallest number of potential cases.

Polio eradication needs of a broad case of definition to identify any polio cases widely. Specific case definition relates to identifying specific cases in newly investigating disease condition.
