Today it is well demonstrated that stethoscopes can be as contaminated as hands, which are a recognized source of Health-Care Associated Infections (HCAIs). Ultraviolet C (UVC) light has proven disinfection capacity and the innovative UVC technology of Light Emitting Diode (LED) shows several potential benefits. To verify whether the use of UVC LEDs is effective and reliable in stethoscope membrane disinfection after prolonged use, a pre-post intervention study was conducted. A total of 1668 five-minute cycles were performed on two UVC LEDs to simulate their use; thereafter, their disinfection capacity was tested on stethoscope membranes used on a previously auscultated volunteer. Then, a further 1249 cycles were run and finally the LEDs were tested to assess performance in reducing experimental contamination by Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli on the stethoscope membrane. Baseline volunteer contamination identified 104 Colony Forming Units (CFUs) while treated Petri dishes had 12 and 15 CFUs (p < 0.001). Statistically significant differences (p < 0.001) were also found relating to the reduction of specific bacteria: in particular, after treatment no CFU were observed for S. aureus and E. coli. UVC LEDs demonstrated the capacity to maintain high levels of disinfection after more than 240 h of use and they were effective against common microorganisms that are causative agents of HCAIs.

In May 2018, the non-governmental organization (NGO) Doctors with Africa CUAMM began to implement an intervention to strengthen Chiulo Hospital’s public health section to deliver immunization services in Mucope Comuna, Ombadja District. We aimed to evaluate the effect of this intervention. During the intervention period, actions such as staff training, improvement in the monitoring of vaccine stockpile, and the involvement of Community Health Workers were performed. The effects of the intervention on the number of vaccine doses administered were examined using negative binomial regression. Doses administered were 14,221 during the intervention period and 11,276 in the pre-intervention one. The number of administered doses was 26% higher (95% CI 9%–45%) in the intervention period than in the pre-intervention period. This was driven by vaccine doses administered during outreach sessions, where a statistically significant increase of 62% (95% CI 28%–107%) was observed. Regarding individual vaccines, statistically significant increases in the number of doses were observed for OPV2 (76%), OPV3 (100%), Penta3 (53%), PCV3 (53%), and Rota2 (43%). The NGO interventions led to improved delivery of immunization services in the study area. Greater increases were observed for vaccine doses that are more likely to be missed by children.

Background: Immunization represents one of the most effective intervention in public health. In the Sustainable Development Goals era, adequate vaccination services are still crucial for the prevention of infectious diseases and the reduction of under-5 mortality. However, in 2017 WHO estimated that children <1 year who did not receive the third dose of Diphtheria-Tetanus-Pertussis (DTP3) vaccine were 19.2 million globally, and 600000 of these were located in Angola, a Sub-Saharan country with an estimated DTP3 coverage of 52%. Since 2000, Italian Non-Governmental Organization (NGO) Doctors with Africa CUAMM supports the activity of the hospital of Chiulo in the commune of Mucope (district of Ombadja, south of Angola). Aim of the study is to describe the interventions implemented to strengthen the immunization services performed by the hospital Public Health Staff (PHS). Methods: In May 2018 the NGO started to implement multiple interventions to enhance the number of vaccine doses administered. Firstly, outreach immunization sessions were reorganized and reinforced, for example involving local Community Health Workers in the identification of villages with a high burden of unvaccinated children. Other actions were the continuous training of the PHS in data collection and the increased collaboration with the Ombadja District Health Department in order to develop a more efficient vaccine supply chain at local level. Results: In 2018, among children <1 year the PHS administered 19746 doses, with a 22.3% growth compared to 2017 (15349 doses). Doses administered during outreach sessions increased by 35.4% (6597 versus 4259 doses). Estimated DTP3 coverage in Mucope commune was 71% (2017, 59%). Conclusions: The WHO “Reaching Every Community” strategy emphasizes the importance of high quality immunization services in hard-to-reach areas. The organisation of well-functioning immunization services requires a multifaceted approach by the involved stakeholders. Key messages: In 2017, globally 19.2 million of children <1 year did not receive the recommended three DTP doses. Six-hundred thousand were located in Angola. To obtain and sustain an adequate vaccination coverage, especially in hard-to-reach areas, multiple and well-coordinated actions should be implemented by all the involved stakeholders.
