Description
In the years following the HIV epidemic, much has changed in the way of public health, the social epidemic of stigma has remained. It is the assertion of the authors that stigma can be combatted through the propagation of accurate education and exposure to the lasting negative impacts of social stigma on persons living with HIV in the United States at present. Although individuals who are not apart of this community cannot truly understand the impacts of HIV-related stigma on those directly impacted by it, a sense of understanding and compassion may be elicited through the breakdown of social stigma into comprehensible components and the provision of stigma-inspired artwork. In addition to providing a background on the scientific basis of Human immunodeficiency virus and its spread, the authors have elected to utilize public engagement by means of an anonymous survey as well as personal interactions with HIV advocates to synthesize paintings. Responses were collected from approximately 300 survey participants via social media with no demographic information collected. It was the hope of the authors that the lack of identifying questions may prompt participants to answer freely and honestly to improve overall understanding of social perceptions of HIV and its related stigma. These paintings and resources deemed appropriate based on the results of the aforementioned survey are to be displayed on a webpage for easier access and engagement with a broader audience.Moreover, this webpage is intended to be maintained and utilized beyond the timeframe of this Undergraduate Honors Thesis for the intended purpose of promoting stigma-free HIV advocacy and education.

Description
Blood donations today undergo extensive screening for transfusion transmitted infections (TTI) since the discovery of the first infectious agent in the early 1900s. Nucleic Acid Testing (NAT) is a serological test used widely in disease detection. NAT is known to rapidly and effectively detect pathogenic genomic material in blood by reducing the "window period" of infection. However, NAT produces false negative results for disease positive samples posing a risk of disease transmission. Therefore, NAT is used in conjunction with the Enzyme-Linked Immunosorbent Assay (ELISA) to mitigate these risks. However, the ELISA assay also poses the same risk as NAT. This study proposes immunosignaturing as an alternative serological test that may combat this risk and investigates whether it would be more effective than other standardized serological tests in disease detection. Immunosignaturing detects antibodies by utilizing a microarray of randomized peptide sequences. Immunosignaturing provides information about an individual's immune health from the pattern of reactivity of antibody-peptide binding. Unlike ELISA and NAT, immunosignaturing can be programmed to detect any disease and detect multiple diseases simultaneously. Using ELISA, NAT, and immunosignaturing, immune profiles of asymptomatic patients were constructed for 10 different classes of blood borne diseases. A pattern of infection was identified for each disease and the sensitivity and specificity of these assays were assessed relative to each other. Results indicate that immunosignaturing can be a viable diagnostic tool in blood testing. Immunosignatures demonstrated increased sensitivity and specificity compared to ELISA and NAT in discerning disease positive and negative samples within and across different classes of disease.
