Background: Detection of acute (pre-seroconversion) HIV infection (AHI), the phase of highest transmission risk, requires resource-intensive RNA- or antigen-based detection methods that can be infeasible for routine use. Risk score algorithms can improve the efficiency of AHI detection by identifying persons at highest risk of AHI for prioritized RNA/antigen testing, but prior algorithms have not considered geospatial information, potential differences by sex, or current antibody testing paradigms.
Methods: We used elastic net models to develop sex-stratified risk score algorithms in a case-control study of persons (136 with AHI, 250 without HIV) attending a sexually transmitted infections (STI) clinic in Lilongwe, Malawi from 2015 to 2019.
Introduction: Uptake of voluntary medical male circumcision (VMMC) remains a challenge in many settings. Innovative implementation strategies are required to scale-up VMMC uptake.
Methodology: RITe was a multi-faceted intervention comprising transport reimbursement (R), intensified health education (IHE) and SMS/Telephone tracing (Te), which increased the uptake of VMMC among uncircumcised men with sexually transmitted infections (STIs) in Malawi.
Background: Genital ulcer diseases (GUDs) are a common syndrome associated with sexually transmitted infections. Genital ulcer diseases increase the risk of HIV transmission, necessitating appropriate diagnosis and treatment. We provide an updated GUD etiology assessment in Malawi to guide diagnostic development and treatment algorithms.

Design: Pragmatic preinterventional and postinterventional quasi-experimental study combined with a prospective observational design.
Setting: A public and specialised STI clinic in Lilongwe, Malawi.
Objectives: To examine the time required to suppress HIV in the genital tract with antiretroviral therapy (ART) in men with urethritis.
Design: An observational cohort study.
Methods: Men with HIV and urethritis not on ART were enrolled at an STI clinic in Malawi and offered to initiate ART.
Background: Understanding heterogeneity across patients in effectiveness of network-based HIV testing interventions may optimize testing and contact tracing strategies, expediting linkage to therapy or prevention for contacts of persons with HIV (PWH).
Setting: We analyzed data from a randomized controlled trial of a combination intervention comprising acute HIV testing, contract partner notification (cPN), and social contact referral conducted among PWH at 2 STI clinics in Lilongwe, Malawi, between 2015 and 2019.
Methods: We used binomial regression to estimate the effect of the combination intervention vs.
Understanding depression, alcohol use, and sexual behaviors according to HIV infection stage and diagnosis timing is important for HIV prevention efforts. We enrolled persons with recent infection and diagnosis (i.e.

Identifying individuals most likely to benefit from PrEP and retaining them on PrEP throughout HIV risk is critical to realize PrEP's prevention potential. Individuals with sexually transmitted infections (STIs) are an obvious priority PrEP population, but there are no data from sub-Saharan Africa (SSA) confirming the effectiveness of integrating PrEP into STI clinics.

Employing multiple HIV testing strategies in tandem could increase HIV detection and promote linkage to care. We aimed to assess an intervention to improve HIV detection within socio-sexual networks of PLWH in two sexually transmitted infections (STI) clinics in Lilongwe, Malawi.

This study aims to better evaluate HIV shedding in men with urethritis receiving ART, and its implications for the cure of HIV.
Methods: Men living with HIV with urethritis taking ART ≥12 weeks were enrolled at a sexually transmitted infections clinic in Lilongwe, Malawi.
Monitoring the burden of and trends in sexually transmitted infection syndromes is useful in informing syndromic management guidelines. Among sexually transmitted infection clinic patients in Lilongwe, Malawi, between 2006 and 2015, genital discharge, lower abdominal pain, and genital ulcer syndromes were common. Prevalence of most syndromes remained stable during the 10-year period.

We used rapid serology tests for syphilis screening at a Malawian sexually transmitted infections clinic. The estimated seroprevalence was 9% and was highest among patients with genital ulcers (26%) and newly diagnosed HIV infection (19%).

We aimed to compare two strategies for recruiting male partners for CHTC in Malawi's option B+ prevention of mother-to-child transmission programme: invitation only versus invitation plus tracing and postulated that invitation plus tracing would be more effective.
Methods: We did an unblinded, randomised, controlled trial assessing uptake of CHTC in the antenatal unit at Bwaila District Hospital, a maternity hospital in Lilongwe, Malawi.
Objectives: HIV-infected women identified through antenatal care (ANC) often fail to access antiretroviral treatment (ART), leaving them and their infants at risk for declining health or HIV transmission. We describe results of measures to improve uptake of ART among eligible pregnant women.
Methods: Between October 2006 and December 2009, interventions implemented at ANC and ART facilities in urban Lilongwe aimed to better link services for women with CD4 counts <250/μl.
