Introduction: We assessed trends in HIV and syphilis prevalence, HIV incidence, related risk factors, and preventive behaviors among men who have sex with men (MSM) in Vietnam from 2015 to 2020.
Methods: Data originated from the HIV Sentinel Surveillance Plus system, which sampled MSM at venues and hotspots in seven of Vietnam's 63 provinces in 2015, 2016, 2018, and 2020 ( = 1100-1445 per year; ∼150-300 per province per year).
Results: HIV prevalence estimates increased from 6.
We report on an outbreak of nongroupable Neisseria meningitidis-associated urethritis, primarily among men who have sex with men in southern Vietnam. Nearly 50% of N. meningitidis isolates were resistant to ciprofloxacin.

We determined HPV prevalence and HPV vaccine knowledge among female university students in Vietnam.
Patients And Methods: We surveyed and screened 1,491 female university students in Hanoi, Hue, and Ho Chi Minh City for their sexual behaviours, HPV knowledge and low- and high-risk HPV infection.
Background: HIV/AIDS program managers in Ho Chi Minh City (HCMC), Vietnam have always relied on the police reports and the UNAIDS Estimation and Projection Package for population size estimation of People Who Inject Drugs (PWID).
Methods: We used Respondent-driven Sampling (RDS) to implement a two-source capture-recapture study to estimate the population size of PWID in HCMC in 2017. The study was implemented in seven out of 24 districts and included men and women ages 18 years and older who reported injecting illicit drugs in the last 90 days, and who had lived in the city for the past six months.
A total of 2768 MSM participated in a survey in southern Vietnam. Univariate and multivariate logistic regression analyses were performed to determine predictors of HIV infection. The prevalence of HIV among MSM was 2.

- - The study aimed to assess the prevalence of pretreatment drug resistance (PDR) to first-line antiretroviral drugs among HIV patients starting treatment in Vietnam, with data collected from 2009 to 2010 across various clinics.
- - Out of 490 participants with detectable viral loads, 3.5% exhibited drug-resistance mutations, with a higher prevalence found in individuals who injected drugs (4.0%) compared to those with sexually acquired HIV (1.4%).
- - The findings suggest that PDR to first-line antiretroviral drugs is low in Vietnam, indicating that first-line treatments are likely effective, though ongoing monitoring and prevention strategies are necessary to maintain this low resistance rate.
Background: Risk behaviors among female sex workers (FSW) are considerable drivers of HIV infections in Vietnam, especially transmission between high-risk and low-risk groups. We assessed HIV prevalence and its correlates among FSWs, and the use of preventive services among this community in the Mekong Delta region, southern Vietnam.
Methods: A cross-sectional survey of 1,999 FSWs was carried out in five provinces including Ben Tre, Hau Giang, Kien Giang, Tien Giang, and Vinh Long between June, 2006 and June, 2007.
Background: The prevalence of HIV and sexually transmitted infections among men who have sex with men (MSM) has increased substantially in Vietnam. This study aimed to estimate the prevalence of HIV, syphilis, urethral gonorrhoea, and urethral chlamydia, and determined correlates of HIV infection among MSM in An Giang, Vietnam.
Methods: A group of 381 MSM were recruited in a community-based cross-sectional survey between August and December 2009.
To determine the prevalence of HIV and correlates of HIV infection among female sex workers (FSWs) in Soc Trang province, Vietnam, a survey of 406 FSWs in Soc Trang province was conducted between May and August, 2003. The participants were interviewed, using a standardized interview, to obtain information about socio-demographic and behavioral characteristics, and gynecologic and sexually transmitted infection (STI) history. The prevalence of HIV was 3.

Study Design: Four hundred and six FSWs in Soc Trang province participated in a cross-sectional study between May and August, 2003. The study subjects were interviewed to obtain information about socio-demographic and behavioral characteristics and gynecologic and STI history, using a standardized interview.
