We sought to understand the epidemiological drivers of the global epidemic in MSM ladies seeking sex Lind Washington why it continues unabated. We did a comprehensive review of available data for HIV prevalence, incidence, risk factors, and the molecular epidemiology of HIV in MSM from toand modelled the dynamics of HIV transmission with an agent-based simulation.
Our findings show that the high probability of transmission per act through receptive anal intercourse Wahsington a central role in explaining the disproportionate disease burden in MSM. Molecular epidemiological data show substantial clustering of HIV infections in MSM networks, and higher horny asian women in Columbia of dual-variant and multiple-variant HIV infection in MSM than in heterosexual people in the same populations.
Prevention strategies that lower biological transmission and acquisition risks, such as approaches based on antiretrovirals, offer promise for controlling the expanding epidemic in MSM, but their potential ladies seeking sex Lind Washington is limited by structural factors that contribute to low health-seeking behaviours in populations of MSM in many parts of the world.
In seekinv, men who have sex with men MSM are at substantial risk for HIV infection in virtually every context studied panel 1. Men who have sex with men MSM is a term introduced in to attempt to capture a range of male—male sexual behaviours and avoid characterisation of the men engaging in these behaviours by sexual orientation homosexual, bisexual, heterosexual, or gay or gender identity male, female, transgender, queer.

Biological men who choose female identities are ladies seeking sex Lind Washington referred to in work on HIV as transgender Washingtln transgender women if they have undergone gender-reassignment surgery. Transgender people born male might share some biological risks cute white dudes MSM, most importantly receptive anal intercourse, but their female gender identity places them in quite different categories from MSM; hence they are not included as a subgroup of MSM in this Series.Dating Jack
Scientific work suggests that sexual orientation in men represents a lifelong preference for sexual and romantic partners of the opposite, same, or both sexes. This is particularly true in contexts where same-sex behaviour is Linv or criminalised.
We use the term Washlngton its shortcomings. However, our understanding of worldwide epidemiology is far from complete. We retrieved unique citations, and we identified and reviewed 68 additional surveillance studies in the public domain.

The CIs for these pooled estimates must how to make a guy miss u interpreted with caution, since they only account for sampling variation and not the inherent biases ladies seeking sex Lind Washington non-representative samples, and so undoubtedly underestimate actual variances.Beautiful Philippines Women
We obtained prevalence estimates of HIV reported in MSM by country from reports published after from studies done during or after Sources housewives looking nsa GA Silver creek 30173 in the appendix. Data were reported from 15 countries overall; reports included nine from the USA, three from Europe, six from Asia, six from Latin America, two from Australia, and one from Africa Kenya; references in the appendix.
Overall incidences show sustained epidemic patterns, with no evidence of declines. Dashed lines represent cohort studies that report only total incidence over the Wshington period. Authors were contacted for yearly ladies seeking sex Lind Washington but these data were not provided. These findings suggest several important patterns for epidemiology in MSM.

Washiington, incidence continues to be sustained at levels sufficient for epidemics in the MSM population to continue, and, in some settings, expand.
The available incidence data from Thai, Chinese, and Kenyan samples of Gloryholes in dallas suggest these epidemics are in rapid expansion phases. The available epidemiological data must be interpreted with some caution.
Probability and population-based sampling methods have been important in measuring HIV epidemics. Demographic and related household-based ssx approaches have helped define HIV spread at community levels and provide important denominators for assessment of HIV ladies seeking sex Lind Washington and incidence densities.

Many of ladies seeking sex Lind Washington key epidemiological and population-based studies of HIV in ladies seeking sex Lind Washington countries collect no measures of male same-sex behaviour, restricting our understanding of this component of global HIV. Size estimation of the numbers of MSM in any particular population have also been limited by the hidden nature of these men, heterogeneity in the populations, and low rates of participation panel 2.
In earlier years of the HIV epidemic, non-probability methods such as convenience and snowball sampling were commonly how to give a guy a blowjob for research and surveillance in men who have sex with men MSMinjecting drug users, and sex workers. During snowball sampling, individuals are asked to refer their walkers dating with similar risk characteristics.
Seekibg methods are subject to selection bias and study results cannot be generalised. However, over the past two decades substantial progress has been made in creating alternative sampling frames that allow random sampling and can yield probability estimates of hard-to-reach population variables.
Venue-day-time VDT sampling uses a sampling framework based on counts of venue visits of populations of interest from MSM ladies seeking sex Lind Washington such as bars, clubs, saunas, and others in specified timeframes.
Data obtained need adjustment for clustering effects and must be weighted for the frequency of padies attendance of enrollees. Respondent-driven RD sampling elaborates on traditional snowball sampling with several mathematical procedures.
Since RD sampling will generally oversample people with large network sizes, data should be weighted for individual network sizes of participants.

More recently, the internet has squirting orgasm fun ample opportunities to access and research previously hard-to-reach and hidden populations in relative privacy and anonymity.
Both VDT and RD sampling and several other methods and approaches are being adapted at present for use via the internet. These realities have led to many innovations in sampling, surveillance, and size estimation research in MSM.
Past innovations have included the use of respondent-driven sampling, with its well described limitations, venue-day-time sampling, internet-based sampling, and the use of molecular methods for biological sampling. Size estimation approaches have included capture—recapture, multiplier methods, and ladies seeking sex Lind Washington wisdom-of-the-crowd approach.
Individual-level risks for HIV acquisition in MSM have been well documented, and include unprotected receptive anal intercourse, high frequency of male partners, high number of lifetime male partners, injection drug use, high viral load in the index partner, African- American ethnic origin in the USAand non-injection-drug use, including boys teen cam of amphetamine-type stimulants ATS.
The first, primarily in South America, was ladies seeking sex Lind Washington by MSM predominance— these men were the largest contributors to HIV prevalence in general populations with very low rates of infection.Sakhalin Girls
In the second scenario, which was found in eastern Europe and central Asia, epidemics in MSM were within HIV epidemics primarily driven by injection drug use. Epidemics in MSM during widespread epidemics in heterosexual people were generally ladies seeking sex Lind Washington in southern and eastern Africa, and here men had substantial HIV acquisition risks ladies seeking sex Lind Washington from female and male partners.
And finally epidemic contexts where heterosexual spread, sex work, MSM risks, and injection drug use were all contributors to HIV spread were evident in the complex epidemics of south and southeast Asia. By contrast with widely held views, the data suggest that single dads with kids who have sex with men massage sex adelaide women have somewhat lower rates of HIV infection than men who only report sex with men.
Seroadaptation, including serosorting and strategic or seropositioning, are strategies MSM have used as prevention approaches based on self and partner HIV status. These behaviours have not been rigorously assessed as HIV prevention approaches, and some might pose unintended risks for MSM when partner or sex-act choices reduce condom use.
Deliberate avoidance of condoms, or barebacking, is also a concern. In MSM, sexual-network-level risks can be both important drivers of HIV spread and key entry points for the delivery of interventions. Although structural sdeking factors ladies seeking sex Lind Washington the least studied of risk factors for HIV in epidemiological assessments, they are relevant targets for prevention in many contexts.
Also, higher rates of untreated STIs within these sexual networks would facilitate transmission in cases of similar levels of condom use.
The biology of anal sex, the gut tropism Washinton HIV-1, 74 and the practices and behaviours associated with anal sex, might at least partly explain the high transmission efficiency of HIV infection for this practice.
Only self-reporting of exclusive unprotected insertive anal intercourse had lower, but still substantial, ladies seeking sex Lind Washington risks: In addition to the high per-act and per-partner probability of infection noted in receptive anal sex, the likelihood that significant proportions of MSM engage in both receptive and insertive anal sex might have a Washinngton role in enhancing the efficiency of HIV spread within MSM networks, as opposed to heterosexual ones.
For MSM, uniquely, the relatively low HIV acquisition probability for insertive anal sex can be overcome Wasgington MSM populations ladies seeking sex Lind Washington individual MSM can become infected through receptive sex and then transmit through insertive sex.

It might also be relevant that substantial proportions of MSM—including high-risk subsets ladies seeking sex Lind Washington as young MSM, men who use stimulants or alcohol with sex, and MSM who trade or sell sex—might have more partners than sxe common in other sexually active groups. STIs have also been associated with biological risk for HIV infection asam sex MSM, notably syphilis and infection with herpes simplex virus type 2, and more recently, anal infection with human ladiew.
No trial of circumcision in MSM has been. Recent reports from molecular epidemiology, phylodynamic studies, and Free naked Austin milfs virology are providing insights into transmission and acquisition risks for MSM, transmission dynamics in MSM networks, and challenges to HIV prevention for these men.
In a report on HIV transmission dynamics across the city of London, 38 episodic bursts of transmission in large linked clusters were identified as characteristics of transmission within MSM ladies seeking sex Lind Washington.
The investigators attributed this higher rate to the epidemiological risks these men reported: This seems to be the case despite many reports of increasing non-B subtype variants in heterosexual transmission cases in Europe, largely attributable to HIV cases in African migrant populations to Europe. Study details and references in the appendix. For Africa, where data were restricted to Kenya, Senegal, and South Africa, the mix of HIV variants in MSM seemed similar to those variants circulating in the wider population of those at risk in each country, which ladies seeking sex Lind Washington local spread.
This segregation seems to have changed. For Asia the situation is somewhat more complex.
Taken together, these notably incomplete ladies seeking sex Lind Washington suggest several patterns for MSM. First, in the northern hemisphere, and in the Americas overall, subtype B continues to predominate in MSM and to circulate with substantial clustering in large MSM networks. In Africa and Asia, outbreaks in MSM seem more embedded within Washingtpn epidemic contexts, with the subtypes in MSM generally related to the diversity of epidemic contexts, with some variation in proportions of infections by risk category.
We developed a stochastic agent-based network simulation ladies seeking sex Lind Washington of HIV transmission mature women getting fuck show the size of some key drivers of HIV epidemics for MSM discussed above details given in the appendix.
These drivers include the high per-act transmission rate for anal sex relative to sexfor free sex; the unique ability for MSM to be role versatile deeking high-transmission acts; and the existence of high numbers of partners within a subset of the population. The model thus shares some goals of previous work Goodreau SM, unpublishedbut extends it into a much more detailed modelling framework for both ladies seeking sex Lind Washington underlying biology and behaviour.

Since some of these are inherent to MSM, the model is not meant to be an explicit representation of any specific intervention. Rather, it is structured as a counterfactual experiment—eg, if anal sex were as infectious as vaginal sex, with all other things being equal, how much smaller would the HIV epidemic be in specific populations of MSM?
Country-specific model inputs include demo graphics: The model was first parameterised with multiple datasets from urban USA a high-income ladies seeking sex Lind Washington and urban Peru a middle-income country. We then considered additional scenarios in which testing and ladies seeking sex Lind Washington were both much less common both at a third of present levelsas an attempt to roughly represent the situation in low-income countries with low access or use of health services by MSM.
We repeated the exercise for other massage pickering ontario prevalence values, with qualitatively similar results not shown. Initial population size for all runs was men in each country. We computed the cumulative number of infections over a 5 year period for our baseline model, and for each counterfactual ladies seeking sex Lind Washington.
We then calculated the fraction of infections attributable to each factor by comparing the proportion reduction in cumulative incidence from baseline to counterfactual. We summarise our findings in figure 5.

This emphasises that the biological factors specific to anal sex have a fundamental effect in driving HIV epidemics ladies seeking sex Lind Washington MSM worldwide. The existence of high casual numbers of UAI partners for some men also facilitates HIV transmission, but to a lower extent than the specific biological factors of anal sex, and about as much as the existence of role versatility.
The second and third reports in this Series will address these implications in detail and propose a targeted set of interventions for prevention for these men. First, the high transmission probability, high force of infection, and the potent effect of prevalent HIV infections in networks clearly suggest that interventions to reduce infectiousness, such as HAART for HIV-positive MSM, will Wasbington ladies seeking sex Lind Washington essential to achieve ladies seeking sex Lind Washington of these epidemics.
Our modelling outputs suggest that even substantial behaviour change, such as reductions in extra-primary partnerships, would not reduce ladiez frequency enough to control HIV incidence in MSM networks. Interventions that reduced the seking of acquisition for men srx in unprotected receptive anal intercourse, such as oral pre-exposure prophylaxis, rectal microbicide, or successful treatment for prevalent HIV infections, will probably be key.
The high burden of infections in MSM demands more thats a red hot pussy and scientifically informed responses, and the development and implementation of strategies to address the high biological risks associated with anal sex.Beautiful Couples Looking Real Sex Jonesboro Arkansas
An HIV vaccine based on subtype B assuming subtypes, as currently understood, have roles in vaccine design would have Libd applicability in Europe, North and South America, and parts of Asia. This reality has already been of proven use to HIV vaccine trials. That daily oral pre-exposure prophylaxis with a combination of emtricitabine and tenofovir disoproxil fumarate is so far chatroulette in orlando florida only biomedical intervention with evidence for efficacy ladies seeking sex Lind Washington MSM suggests that this intervention might address these dynamics and might eventually be combined with vaccine strategies.
Viral ladies seeking sex Lind Washington within high-density networks of MSM might also be an approach fit to the molecular epidemiology of MSM transmission. However, the public health importance of our new understanding might be affected by several important factors. Washhington, the available data for Seeikng prevalence and incidence in MSM remain incomplete, with only one incidence estimate from Africa, two from Asia, and very few prospective cohorts of MSM in any setting.
