The rapid spread of cases through different countries has raised serious concerns among public health officials worldwide prompting accelerated investigations aimed to identify the origins and cause of the rapid expansion of cases. The current situation is reminiscent of the very early stages of the still ongoing COVID-19 pandemic. Overlapping features between these, two seemingly alike viral entities include the possibility for airborne transmission and the currently unexplained and rapid spread across borders. Early recognition of cases and timely intervention of potential transmission chains are necessary to contain further outbreaks. Measures should include rapid and accurate diagnosis of cases meeting case definitions, active surveillance efforts, and appropriate containment of confirmed cases. Governments and health policymakers must apply lessons learned from previous outbreaks and start taking active steps toward limiting the recent global spread of monkeypox.

MSM account for the mostly affected group, reaching 59% of all the new cases. A review of the HIV determinants was conducted using an ecological framework. At the individual level, sexual abuse, alcohol, and drug consumption were identified as determinants of HIV infection in this population. Family rejection was recognized as a determinant at the interpersonal level. Connection to the gay community can function as a protective factor but it can also be possible predictor of HIV infection. Among structural factors, poverty was found to be positively associated with HIV prevalence. Additionally, we highlighted the importance of sexual health education and especially pre-exposure prophylaxis (PrEP) as protective factors. By using systems thinking tools, we designed a causal loop diagram that illustrates visually the recognized determinants of public health. Finally, we presented several studies that evaluate evidence-based interventions to improve the uptake and retention in care of PrEP in MSM.

All patients (age ≥18 years) with suspicion of COVID-19 with SARI (severe acute respiratory infections) who were subjected to RT-PCR testing (nasal/oropharyngeal swab) were included.
