Diamonds and viruses
In 1988, the remote mining town of Dundo, in Lunda-Norte, Angola, displayed an anomalously high HIV-1 prevalence of 14.2%, despite the absence of recognised epidemic drivers. Archival and epidemiological evidence suggests that colonial medical interventions, rather than sexual transmission alone, were central to the early amplification of the virus. Under the Companhia de Diamantes de Angola (Diamang), a vast corporate health system promoted exte…
Acute malnutrition and food insecurity in Yemen, 2021
The ongoing conflict in Yemen, which began in 2014, has led to one of the world’s most severe humanitarian crises. The Hudaydah region, located on the Red Sea coast and home to the country’s second-largest port, is critical for the delivery of food and medical supplies. We conducted a two-stage cluster randomised survey to estimate the prevalence of acute malnutrition among children and pregnant and lactating women (PLW). We estimated the prevale…
Wastewater Metavirome Diversity
This study investigates viral composition in wastewater through metagenomic analysis, evaluating the performance of four bioinformatic tools-Genome Detective, CZ.ID, INSaFLU-TELEVIR and Trimmomatic + Kraken2-on samples collected from four sites in each of two wastewater treatment plants (WWTPs) in Lisbon, Portugal in April 2019. From each site, we collected and processed separately three replicates and one pool of nucleic acids extracted from the…
Seroprevalence and Risk Factors of STIs among Rejected Blood Donors at the National Blood Transfusion Service in Angola
Sexually transmitted infections (STIs) are a global health concern. Blood donation centres employ comprehensive screening measures to identify donors with STIs, such as HIV, HBV, HCV, and syphilis, which can also transmitted through blood transfusions. Herein, we investigated the seroprevalence of STIs and demographic determinants related to multiple infections among rejected blood donors at the National Blood Transfusion Service (NBTS) in Angola…
Serological screening in a large-scale municipal survey in Cascais, Portugal, during the first waves of the Covid-19 pandemic
Background: Serological surveys for SARS-CoV-2 were used early in the COVID-19 pandemic to assess epidemiological scenarios. In the municipality of Cascais (Portugal), serological testing combined with a comprehensive socio-demographic, clinical and behavioral questionnaire was offered to residents between May 2020 and beginning of 2021. In this study, we analyze the factors associated with adherence to this municipal initiative, as well as the s…
Determinants of HIV late presentation among men who have sex with men in Portugal (2014–2019)
Introduction: HIV late presentation (LP) remains excessive in Europe. We aimed to analyze the factors associated with late presentation in the MSM population newly diagnosed with HIV in Portugal between 2014 and 2019. Methods: We included 391 newly HIV-1 diagnosed Men who have Sex with Men (MSM), from the BESTHOPE project, in 17 countrywide Portuguese hospitals. The data included clinical and socio-behavioral questionnaires and the viral genomic …
Dynamics and features of transmission clusters of HIV-1 subtypes in the state of São Paulo, Brazil
Background Molecular epidemiology techniques allow us to track the HIV-1 transmission dynamics. Herein, we combined genetic, clinical and epidemiological data collected during routine clinical treatment to evaluate the dynamics and characteristics of transmission clusters of the most prevalent HIV-1 subtypes in the state of São Paulo, Brazil. Methods This was a cross-sectional study conducted with 2,518 persons living with HIV (PLWH) from 53 citi…
Are immigrants more vulnerable to the socioeconomic impact of Covid-19? A cross-sectional study in Amadora Municipality, Lisbon metropolitan area
To the best of our knowledge, this study is the first to capture the direct socioeconomic impact of COVID-19 among immigrants and natives in Portugal. It highlights the bidirectional relation between inequalities deeply rooted among immigrants and COVID-19. Socioeconomic inequalities affect local patterns of COVID-19 burden, as confirmed in previous studies, but COVID-19 also has an impact on the economic wellbeing of Amadora immigrants during th…
Determinants of Late HIV Presentation at Ndlavela Health Center in Mozambique
Factors that are potentially determinant for late HIV presentation were identified. Actions are needed to focus on risk factors that are most likely to delay presentation
