Why is a false-positive more significant in HIV testing of patients than in screening donated blood for transfusions?
Discuss current US state policies on vaccination requirements. If no vaccine is available, describe any current R&D or clinical trials in effect right now.
All of the following are true concerning the Alere HIV test except:
a)this test can detect infection 10 days post exposure
b)the presence of three lines on the test indicates a positive reaction for anitgen and antibody against HIV
c)unlike Oraquick the test is run with blood sample only and not oral fluid
d)the presence of a single line indicates that a person has antibodies but no antigen for HIV
e)this is a test that is considered both a direct and indirect test for HIV diagnosis

- Why is it important to get vaccinated against COVID-19? Choose the best answer. * It ensures that the person will not be infected by the virus. No answer It lowers the risk of contracting the disease. It protects the individual and his/her family. It protects the whole community, including those who cannot be vaccinated.arrow_forwardScenario: In a rural community, a primary health care nurse is conducting a door-to-door vaccination campaign to address a recent outbreak of measles. The nurse notices that many parents are hesitant to vaccinate their children due to misinformation. The nurse decides to organize an educational seminar to address these concerns. What approach should the nurse take to effectively communicate the importance of vaccination? Options: A) Use complex medical terms to explain the effectiveness of vaccines. B) Distribute printed materials without engaging in direct conversation. C) Employ a culturally sensitive communication strategy, using simple language and visual aids. D) Recommend vaccination without providing any rationale.arrow_forwardPrior to the development of detection assay for HIV in the blood supply, HCV was used as a proxy. That is to say, any donated blood found to be contaminated with HBV or HCV was also assumed to be HIV positive as well.

- Use this information to answer the question. Human Immunodeficiency viruses, Types 1 and 2 (HIV 1,2) Antibody testing (1985) and NAT (1999) Blood donation screening for HIV-1, the causative agent of AIDS began with antibody testing in 1985. Many improvements in testing have occurred including adding the detection of a second HIV agent (HIV-2 in 1992). A chemiluminescent immunoassay (ChLIA) is used for the qualitative detection of antibodies to HIV-1 and HIV-2. A duplex nucleic acid test (NAT) was introduced for HIV-1/HCV RNA detection in 1999, and updated to include the detection of HBV DNA in 2009 (see above). The next version of NAT will include HIV-2 RNA detection (to be implemented in 2020). Donors who test antibody reactive are further evaluated by additional tests to confirm the presence of HIV antibody and to differentiate HIV-1 from HIV-2 antibodies. Tests for this purpose have included a HIV western blot, an HIV-2 enzyme-linked immunoassay and an HIV-1 and HIV-2 rapid test…arrow_forwardIn no more than 2 paragraphs, explain what vaccines are and how they work.
