Answer 1

5. Those students who got positive result in table 2 are the infected individuals in the classroom.

6.No,if I tested positive for disease exposure,it doesn't mean it's through direct contact only.it might be thorugh indirect blood,non sterile needles etc. (Depends on the disease whether contagious or non contagious)

Transmissibility of disease: It is the proportion of those exposed to the primary case that develop disease as a result of the exposure . It just applies to individual to-individual transmission. It will fluctuate contingent upon the specific circumstance (closeness and kind of contact), just as the disease. It tends to be assessed in circumstances in which the quantity of contacts is referred to, for example, family units or schools. For instance, if 10 individuals in a family are presented to the essential case and 2 get sick the optional assault rate would be 2/10 or 20%

7. Generally we consider negative result means not affected for disease while positive means affected to disease.

insome cases, sample giving negative result for disease causing agent doesn't mean that they donot have the disease.because,some times false results may occour in underlying condition where antibodies are not yet produced.(some antibodies are not produced immediately following infection.) This may result in false report.

•   Reasons for false negative ELISA TEST:
• insufficient HIV-antigen coating of the microtitre plates
• Testing during window period
