ABSTRACT
OBJECTIVES: Exploring fever aetiologies improves patient management. Most febrile adults are outpatients, but all previous studies were conducted in inpatients. This study describes the spectrum of diseases in adults attending outpatient clinics in urban Tanzania. METHODS: We recruited consecutive adults with temperature ≥38°C in a prospective cohort study. We collected medical history and performed a clinical examination. We performed 27 364 microbiological diagnostic tests (rapid tests, serologies, cultures and molecular analyses) for a large range of pathogens on blood and nasopharyngeal samples. We based our diagnosis on predefined clinical and microbiological criteria. RESULTS: Of 519 individuals, 469 (89%) had a clinically or microbiologically documented infection and 128 (25%) were human immunodeficiency virus (HIV) -infected. We identified 643 diagnoses: 264 (41%) acute respiratory infections (36 (5.6%) pneumonia, 39 (6.1%) tuberculosis), 71 (11%) infections with another focus (31 (4.8%) gastrointestinal, 26 (4.0%) urogenital, 8 (1.2%) central nervous system) and 252 (39%) infections without focus (134 (21%) dengue, 30 (4.7%) malaria, 28 (4.4%) typhoid). Of the 519 individuals, 318 (61%), 179 (34%), 30 (6%) and 15 (3%), respectively, had a viral, bacterial, parasitic and fungal acute infection. HIV-infected individuals had more bacterial infections than HIV-negative (80/122 (66%) versus 100/391 (26%); p < 0.001). Patients with advanced HIV disease had a higher proportion of bacterial infections (55/76 (72%) if CD4 ≤200 cells/mm3 and 25/52 (48%) if CD4 >200 cells/mm3, p 0.02). CONCLUSIONS: Viral diseases caused most febrile episodes in adults attending outpatient clinics except in HIV-infected patients. HIV status and a low CD4 level strongly determined the need for antibiotics. Systematic HIV screening is essential to appropriately manage febrile patients.

Self-administration of antibiotics using elastomeric pumps has become the most frequently used treatment modality at the outpatient parenteral antimicrobial therapy (OPAT) unit of the University Hospital of Lausanne. However, it remains unknown how comfortable patients feel using this mode of treatment. A questionnaire was offered to all patients treated at the OPAT unit between June 2014 and December 2015. The questionnaire was distributed to 188 patients and 112 questionnaires were returned. Seventy-one patients were treated by self-administration, 21 attended the OPAT unit on a daily basis, and 20 received their antibiotics from home-care nurses. Overall, 83-97% of the patients gave the highest possible scores to the four items evaluating their global satisfaction. Subjects treated by self-administration gave a significantly better rating to 6 of the 17 semi-quantitative questions than the patients treated at the OPAT unit or by home-care nurses. There was no item which was more poorly rated by patients treated by self-administered OPAT than by the other treatment groups. In conclusion satisfaction was high in all patients treated by OPAT. The particularly high satisfaction of patients treated by self-administration of antibiotics with elastomeric pumps suggests that a significant number of patients are happy to take over some responsibility for their treatment. Patients' capacity to appropriate their care themselves should not be underestimated by health care professionals.

Zika virus is an emerging flavivirus that is following the path of dengue and chikungunya. The three Aedes-borne viruses cause simultaneous outbreaks with similar clinical manifestations which represents a diagnostic challenge in ill returning travellers. We report the first Zika virus infection case imported to Switzerland and present a diagnostic algorithm.
ABSTRACT
The hepatitis B virus is likely to induce a severe disease when the infection occurs in vulnerable individuals. For that reason, clear recommendations are issued that vaccine prevention be offered to the immunocompromised and to the infant newly born to a chronically infected mother. However, the vaccine coverage is definitely suboptimal among these patients and a fair proportion of them are only partially vaccinated. An increase in vaccine coverage is demonstrated in several studies involving dedicated nursing or medical teams. The prevention of hepatitis B infection in vulnerable patients requires a systemic and punctilious approach to such a point that one should consider letting the management of these preventive measures to dedicated nursing or medical teams.
