Article Synopsis
- * Young women (ages 18-24) had a higher HSV-2 seroprevalence (12.1%) compared to adolescents (4.3%), with frequent alcohol consumption also linked to a higher risk of infection.
- * Although vaginal HSV-2 shedding peaked in the third trimester, the difference wasn't statistically significant; nonetheless, this increases the risk of neonatal herpes from vertical transmission during pregnancy.

Article Synopsis
- * Conducted in 2021-2022, the research involved 462 migrants who filled out questionnaires and underwent blood tests to detect these infections, revealing a 29.9% prevalence for HSV-2 and 4.5% for syphilis, particularly higher in men.
- * The findings show that both infections are highly present among the migrant population, highlighting the need for targeted prevention and treatment efforts, especially considering their unique vulnerabilities related to sexual behavior.
Article Synopsis
- * Study findings identify various risk factors for syphilis among MSM, including low economic status, use of inhalant drugs, and specific sexual practices.
- * There is a growing need for targeted prevention efforts in Mexico to address both syphilis and HIV among MSM, particularly considering the increasing prevalence observed in more recent years.

Article Synopsis
- Syphilis is increasingly affecting vulnerable populations globally, and a study conducted from 2011 to 2015 at an HIV clinic in Mexico assessed its prevalence and incidence among various high-risk groups.
- The study analyzed data from nearly 82,000 individuals, finding a seroprevalence of syphilis ranging from 8.2% to 37.0% in different groups, with the incidence being highest among people living with HIV (PLWH) at 16.0 cases per 100 person-years.
- The research also identified risk factors like methamphetamine use, group sex, and online partner contact, indicating an urgent need for improved prevention and treatment strategies to combat syphilis's resurgence.
Article Synopsis
- A study was conducted in a Covid-19 hospital in Morelos, Mexico, to assess the prevalence of SARS-CoV-2 antibodies among healthcare workers (HCW) and identify factors linked to infection.
- The findings revealed that 31% of participants had antibodies, while only 13.1% had tested positive via RT-PCR, with higher seroprevalence seen in social workers (35.7%) compared to laboratory personnel (12.0%).
- The study emphasizes the value of serological testing for accurately assessing infection rates in healthcare settings where only symptomatic cases are typically documented.
