The vertical transmission of certain communicable diseases from mother-to-child during pregnancy and birth is of great concern to public health practitioners because it represents a critical period for intervention. If practitioners can determine at birth whether the disease has been transmitted from mother-to-child, they can act immediately to provide the child with treatment. Syphilis is a disease with high risk for vertical transmission from mother-to-child. If a child becomes infected and is not treated, there can be negative health outcome such as blindness, deafness, and neurological damage. Inspired by the advent of rapid HIV tests that provide quick results and are minimally invasive, suppose that researchers have been working to develop a similar test that can be used for syphilis. After obtaining appropriate institutional approval and patient consent, the researchers test their rapid syphilis test at several birthing hospitals and compare it to the gold standard laboratory…

An epidemiological study involved 674 workers of a vinyl chloride (a plastic manufacturing chemical) manufacturing plant. The study aimed to determine an association between exposure to vinyl chloride and liver cancer. Out of 200 workers who routinely worked in vinyl chloride production area, 15 developed liver cancer. Another group of workers consisting of individuals with smoking histories similar to the plant workers, and who were unlikely to have encountered vinyl chloride, had 24 develop liver cancers and 450 who did not develop liver cancer. a. Given the above information, fill in the 2x2 table below: Exposed: Plant workers Not Exposed: Control group TOTAL b. Calculate the relative risk Developed Liver Cancer Did not Develop Liver Cancer TOTAL 674
