Kissing may be an important and neglected risk factor for oropharyngeal gonorrhoea

Kissing may be an important and neglected risk factor for oropharyngeal gonorrhoea: a cross-sectional study in men who have sex with men

Chow EPFCornelisse VJWilliamson DA, et al

Abstract:

Objectives A mathematical model suggested that a significant proportion of oropharyngeal gonorrhoea cases are acquired via oropharynx-to-oropharynx transmission (ie, tongue-kissing), but to date, no empirical study has investigated this. This study aimed to examine the association between kissing and oropharyngeal gonorrhoea among gay and bisexual men who have sex with men (MSM).

Methods MSM attending a public sexual health centre in Melbourne, Australia, between March 2016 and February 2017 were invited to participate in a brief survey that collected data on their number of male partners in the last 3 months, in three distinct categories: kissing-only (ie, no sex including no oral and/or anal sex), sex-only (ie, any sex without kissing), and kissing-with-sex (ie, kissing with any sex). Univariable and multivariable logistic regression analyses were performed to examine associations between oropharyngeal gonorrhoea positivity by nucleic acid amplification tests and the three distinct partner categories.

Results A total of 3677 men completed the survey and were tested for oropharyngeal gonorrhoea. Their median age was 30 (IQR 25–37) and 6.2% (n=229) had oropharyngeal gonorrhoea. Men had a mean number of 4.3 kissing-only, 1.4 sex-only, and 5.0 kissing-with-sex partners in the last 3 months. Kissing-only and kissing-with-sex were associated with oropharyngeal gonorrhoea, but sex-only was not. The adjusted odds for having oropharyngeal gonorrhoea were 1.46-fold (95% CI 1.04 to 2.06) for men with ≥4 kissing-only partners and 1.81-fold (95% CI 1.17 to 2.79) for men with ≥4 kissing-with-sex partners.

Conclusions These data suggest that kissing may be associated with transmission of oropharyngeal gonorrhoea in MSM, irrespective of whether sex also occurs.

HIV diagnoses in Australia drop to lowest number in 18 years: report

Kirby Institute, July 3rd, 2019

Australia continues to lead the world in HIV prevention and in 2018 recorded the lowest number of HIV diagnoses since 2001.

According to a report released today by the Kirby Institute at UNSW Sydney, last year there were 835 HIV diagnoses across the country, which represents a decline of 23% over five years.

The declines reported today are largely due to reductions in the number of HIV diagnoses that are reported as attributable to sex between men. Over the past five years, HIV diagnoses have reduced by 30% among this population.

The report reveals no declines among heterosexual populations, with new diagnoses relatively stable among this group.

Similarly, there have been no declines in HIV diagnoses among Aboriginal and Torres Strait Islander populations.

Evaluating the cost-effectiveness of existing needle and syringe programmes in preventing hepatitis C transmission in PWID

Drug and Alcohol Findings (UK), 2019

What would happen to rates of infection with hepatitis C if we closed down all the needle exchanges? Research has established that needle/syringe programmes are a cost-effective way to reduce spread of HIV, but just two studies have considered the same issue in relation to hepatitis C.

In three UK municipalities, the answers were predicted to be more infections, lost low-cost opportunities to improve and save lives, and in two of the areas, greater health-related costs overall. Conclusion was that these services are among the best investments UK health services can make.

80% of new HIV cases transmitted by undiagnosed or untreated people

Healio, March 18, 2019

In 2016, more than 80% of new HIV infections in the United States were transmitted by individuals who either did not know they were infected with HIV or had been diagnosed but were not receiving care, according to data released on the first day of the National HIV Prevention Conference in Atlanta.

Cultural and linguistic diversity of people living with chronic hepatitis B

Cultural and linguistic diversity of people living with chronic hepatitis B in 2011–2016: changing migration, shifting epidemiology
Aust NZ J Public Health. 2018; 42:441-3; doi: 10.1111/1753-6405.12826
Abstract
Objective: To estimate the cultural and linguistic diversity in Australians currently living with chronic hepatitis B (CHB), the majority of whom were born overseas, and to identify trends in this diversity over time.
Methods: Estimates were generated by combining Australian census country of birth
information with seroprevalence data generated from antenatal serology linked with
surveillance notifications. The number of people living with CHB was assessed according to country of birth using the 2011 and 2016 censuses.
Results: The total number of Australian residents living with CHB increased by 20% between 2011 and 2016, substantially outpacing population growth. The most common country of birth continued to be China, with the number of Chinese-born Australians living with CHB increasing by 60% in the 5-year period. Decreased numbers were observed for people born in European countries.
Conclusions: The epidemiology of chronic hepatitis B in Australia has shifted over time due to changing migration patterns, with increases in many countries in the Asia-Pacific, African and Middle Eastern regions. 
Implications for public health: Interventions to improve the health of people living with CHB are imperative, and these up-to-date estimates identify priority groups and communities, which are constantly changing.

Scotland’s reduction in new HCV infections is due to harm reduction, not treatment

infohep, Published:12 June 2018

The reduction in new hepatitis C virus (HCV) infections that has taken place in Scotland since 2008 is most likely due to increased provision of needle and syringe programmes and opioid substitution therapy, rather than a reduction in the number of people with hepatitis C as a result of increased treatment of HCV infection, a modelling study published in the journal Addiction reports.

Researchers from the University of Bristol and three Scottish universities developed a model of the Scottish HCV epidemic to test the impact of varying levels of harm reduction provision.
