TL;DR: The results suggest that the risk of HIV transmission in gay couples through condomless sex when HIV viral load is suppressed is effectively zero, which supports the message of the U=U (undetectable equals untransmittable) campaign, and the benefits of early testing and treatment for HIV.
Journal ArticleDOI

TL;DR: A preliminary case series of 33 PLWH patients with COVID-19 reveals symptoms and outcome in this special population and does not support excess morbidity and mortality among symptomatic CO VID-19 PLWH and with viral suppression on ART.
Journal ArticleDOI
High rates of quinolone-resistant strains of Shigella sonnei in HIV-infected MSM.

TL;DR: Retrospective analysis of antibiotic resistance profiles of Shigella species isolated from stool specimens of patients presenting with diarrhea in three German outpatient clinics specialized in HIV care found high rates of S. sonnei isolates resistant to quinolones and other traditional antibiotics are of concern.
Journal ArticleDOI
