1) What is the life cycle of West Nile and how do people fit in?

(a) Mosquito-Human Cycle; the West Nile Virus cycles between Mosquito the vector and humans the reservoir.
(b) Mosquito-Bird Cycle; Mosquito is the primary vector while bird is the reservoir, the virus being spread bird to bird and by the Mosquitoes. Humans are simply a dead end for the virus.
(c) Mosquitoes are both vector and reservoir. Humans just get it by accident.

2) How do you determine whether a person has contracted the virus?

(a) Symptoms are distinct enough to differentiate from other diseases.

(c) Blood test can determine the presence of the virus.
(d) A simple combination of mosquito bite and a few symptoms after bite.

3) What is the cure for West Nile Virus?

(a) There is a vaccine for the West Nile virus.
(b) Anti-seizure medications have been proven in control studies to be effective.
(c) Antibiotics are able to fight of the virus.
(d) There is no cure, Mosquito repellant is the best preventive step.

4) What is the greatest risk factor in regard to patient survival and recovery?

(a) Certain racial groups are particularly vulnerable.
(b) Age significantly affects mortality.
(c) There is no risk factor that affects mortality
(d) West Nile does not cause mortality, all patients recover.

5) Three IgG and IgM techniques were explained and compared, what are
they and which is better than the others?
(a) Standard, Real-time, Multiplex RT-PCR were the techniques and all
techniques have the same sensitivity and price.
(b) IFA, (immunofluorescence assay) ELISA, (enzyme linked immunosorbent
assay) and MAC-ELISA (IgM antibody capture) are all techniques with the
same sensitivity and price.
(c) The two techniques test for the IgG and IgM positive results for
West Nile. IFA (immunofluorescence assay) was found to be more cost effective
and as sensitive as ELISA (enzyme linked immunosorbent assay) and MAC-ELISA
(IgM antibody capture)
(d) None of the above.
