Abstract:

Background: HIV infection is prevalent among men who have sex with men (MSM), and sexual roles may be important factors related to it. This study aims to describe the sexual roles, risky sexual behaviors and HIV prevalence among MSM, and to determine associated factors for HIV prevalence.

Methods: A convenient sampling method was used to recruit participants in a non-government organization in Changsha, China. The participants were asked to complete a 38-item self-administered questionnaire regarding demographic characteristics and risky sexual behaviours before collecting blood samples for HIV testing. Chi-square tests and logistic regression analysis were conducted with the Statistical Package for the Social Sciences Version 18.0 and other indexes were statistically described.

Results: A total of 601 MSMs who came to a local non-government organization for voluntary counseling and testing completed a pencil-and-paper survey and were tested for HIV. The overall HIV prevalence of this sample was 13.3%, and that of the bottoms (16.3%) was similar to the versatiles (15.9%) but higher than the tops (6.1%). Bivariate analyses showed that there were significant differences in age, marital status, monthly income, sexual orientation, age at first sex, sex of the first sex partner, sex with a woman in the last 6 months, oral sex with a man in the last 6 months and role of oral sex among 3 subgroups of MSM (p < 0.05). Multivariate analyses indicated that MSMs who played the role of either the bottoms or the versatiles were more likely to be HIV positive than the tops. While MSMs who used condoms in anal sex in the last 6 months, had sex with a woman in the last 6 months or had oral sex with a man in the last 6 months were less likely to be HIV positive.

Conclusion: Different sexual roles are associated with high-risk sexual behaviors among MSMs and their HIV infection status. Further research should target preventive interventions, and improve the effectiveness of the intervention according to the characteristics of the subgroups to reduce the HIV transmission among Chinese MSM.

An analysis of the HIV/AIDS Epidemic in Taiwan!

The spread of an HIV epidemic has been recorded since the last 10 years in Taiwan.  Especially amongst those people who inject drugs in their veins. There was a hefty increase in patients suffering from HIV/AIDS since the past 3 years.

id-10030956

The exact number of HIV patients had yet to be reported, hence, a research team conducted a survey using a compartmental mathematical model for disease transmission and HIV/AIDS surveillance data during 2001-2011 in which it was observed that the estimated under reporting ratio in 2011 is 0.45:1 decreased from 1:1 ratio in 2000. Based on the assumption that model parameters remain unaltered, a future prognosis was presented of both the reported and the unreported persons living with HIV/AIDS.

An observed data set from 2012-2014 showed lower than the expected number of persons living with HIV/AIDS and new deaths maybe because of increased treatment. On the other hand, the percentage of newly reported HIV/AIDS patients has increased which further warrants investigation.

EurekAlert! – Application of novel alignment-free sequence descriptors in Zika virus characterization

Dr. Basak and his colleagues explained about their research on computer-assisted approaches towards surveillance and consequent design of drugs and vaccines to combat the growth and spread of the Zika virus.

The recent epidemic of Zika virus infections in South and Latin America has raised serious concerns on its ramifications for the population in the Americas and spread of the virus worldwide. The Zika virus disease is a relatively new phenomenon for which sufficient and comprehensive data and investigative reports have not been available to date. Although first recognized as a new virus in 1947 in Uganda’s Zika forest animals, its debilitating effect on human fetuses leading to babies being born with smaller braincases (microcephaly) was not known or well investigated until its epidemic form in Yap Island, Micronesia, in 2013 and now in the South American countries in 2015-16. The concern is so high that public health authorities in some countries such as Colombia, Ecuador, El Salvador, and Jamaica have asked their women to avoid pregnancies until the virus is better understood. The World Health Organization (WHO) has labeled the outbreak of such abnormalities as a Public Health Emergency of International Concern.
