Eligibility criteria for patients include age below 25 years in order to focus on the prevalence of transmitted HIVDR (tHIVDR) in newly-infected individuals. Most of the participating sites across Africa have so far reported tHIVDR prevalences of below 5%. In this study we investigated whether the rate of HIVDR in patients <25 years is representative for HIVDR in the rest of the therapy-naïve population. Methods and Findings HIVDR was determined in 88 sequentially enrolled ART-naïve patients from Mwanza, Tanzania (mean age 35.4 years). Twenty patients were aged <25 years and 68 patients were aged 25–63 years. The frequency of HIVDR in the study population was 14.8% (95%; CI 0.072–0.223) and independent of NVP-resistance induced by prevention of mother-to-child transmission programs. Patients >25 years had a significantly higher HIVDR frequency than younger patients (19.1%; 95% CI 0.095–0.28) versus 0%, P = 0.0344). In 2 out of the 16 patients with HIVDR we found traces of antiretrovirals (ARVs) in plasma. Conclusions ART-naïve patients aged over 25 years exhibited significantly higher HIVDR than younger patients. Detection of traces of ARVs in individuals with HIVDR suggests that besides transmission, undisclosed misuse of ARVs may constitute a significant factor in the generation of the observed high HIVDR rate. The current WHO tHIVDR survey that is solely focused on the transmission of HIVDR and that excludes patients over 25 years of age may therefore result in substantial underestimation of the prevalence of HIVDR in the therapy-naïve population. Similar studies should be performed also in other areas to test whether the so far reported optimistic picture of low HIVDR prevalence in young individuals is really representative for the rest of the ART-naïve HIV-infected population.

However, current data on the care of refugees and migrants in initial reception centers is pending. This article provides data on prescription frequencies of various antibiotics and associated diagnoses. Methods In this retrospective observational study, patient data of 3255 patients with 6376 medical contacts in two initial reception centers in Germany were analyzed. Patient data, collected by chart review, included sociodemographic characteristics, diagnoses, and prescriptions. Antibiotic prescription behavior and corresponding physician‐coded diagnoses were analyzed. Results Nineteen percent of all patients in our study received systemic antibiotics during the observation period, with children below the age of 10 years receiving antibiotics most frequently (24%). The most commonly prescribed antibiotics were penicillins (65%), macrolides (12%), and cephalosporins (7%). The most frequent diagnoses associated with antibiotic prescription were acute tonsillitis (26%), bronchitis (21%), infections of the upper respiratory tract (14%), and urinary tract infections (10%). In case of acute bronchitis 74% of the antibiotic prescriptions were probably not indicated. In addition, we found a significant number of inappropriate prescriptions such as amoxicillin for tonsillitis (67%), and ciprofloxacin and cotrimoxazol for urinary tract infections (49%). Conclusion Regarding inappropriate prescription of antibiotics in refugee healthcare, this study shows a rate ranging from 8% for upper respiratory tract infections to 75% for acute bronchitis. Unnecessary use of antibiotics is a global problem contributing to gratuitous costs, side effects, and antimicrobial resistance. This research contributes to the development of stringent antibiotic stewardship regiments in the particularly vulnerable population of migrants and refugees.
