Evaluate the following test results using acute and convalescent titers for antibodies to Dengue virus:

8. Mary B: Acute IgM = 2; Convalescent IgM = 256

Does Mary have a current Dengue infection? Why or why not?

9. Tom A: Acute IgG = 64; Convalescent IgG = 256

Does Tom have a current Dengue infection? Why or why not?

10. Sylvia P: Acute IgM = 4; Convalescent IgM = 8

Does Sylvia have a current Dengue infection? Why or why not?

8. Mary B: Acute IgM = 2; Convalescent IgM = 256

Does Mary have a current Dengue infection? Why or why not?

Since IgM is positive, it would mean that the person has been infected with the dengue virus, in and around the recent weeks. This would also mean that the possible interpretation would be of a current infection. Since IgM levels are highly low in both acute and convalescent phases, it would imply a primary infection.

9. Tom A: Acute IgG = 64; Convalescent IgG = 256

Does Tom have a current Dengue infection? Why or why not?

Since IgG is positive, it would mean that the person has been infected with the dengue virus, in and around the recent weeks. This would also mean that the possible interpretation would be of a current infection. Since IgG levels are highly low in both acute and convalescent phases, it would imply secondary infection.

10. Sylvia P: Acute IgM = 4; Convalescent IgM = 8

Does Sylvia have a current Dengue infection? Why or why not?

Since IgM is positive, it would mean that the person has been infected with the dengue virus, in and around the recent weeks. This would also mean that the possible interpretation would be of a current infection. Since IgM levels are highly low in both acute and convalescent phases, it would imply secondary infection.

The standard HIV test detects HIV antibodies rather than the virus itself. When a person becomes infected with HIV, it takes a few weeks for the HIV test to indicate a positive result. Based on the information provided, which of the following processes occurs in the time between infection and detection? A) cell-mediated immunity B) more macrophages are produced C) more viruses are produced D) humoral immunity
