RESUMO
BACKGROUND: In early 2016, we implemented a community-based maternal, newborn, and child health (MNCH) surveillance using mobile phones to collect, analyze, and use data by village health volunteers (VHV) in Kenge Health Zone (KHZ), in the Democratic Republic of Congo (DRC). The objective of this study was to determine the perceptions of households, attitudes of community health volunteers, and opinions of nurses in Health center and administrative authorities towards the use of mobile phones for MNCH surveillance in the rural KHZ in the DRC. METHODS: We used mixed methods combining phenomenological and descriptive cross-sectional study. Between 3 and 24 March 2016, we collected the data through focus group discussions (FGD) with households, and structured interviews with VHV, local health and administrative authority, and nurses to explore the perceptions on MNCH surveillance using mobile phone. Data from the FGD and interviews were analyzed using thematic analysis techniques and descriptive statistics respectively. RESULTS: Health issues and services for under-five children were well known by community; however, beliefs and cultural norms contributed to the practices of seeking behavior for households. Mobile phones were perceived as devices that render quick services for people who needed help; and the community's attitudes towards the mobile phone use for collection of data, analysis, and use activities were good. Although some of community members did not see a direct linkage between this surveillance approach and health benefits, majority believed that there would be better MNCH services with the use of mobile phone. In addition, VHV will benefit from free healthcare for households and some material benefits and training. The best time to undertake these activities were in the afternoon with mother of the child, being the best respondent at the household. CONCLUSION: Health issues and services for under-five children are well known and MNCH surveillance using mobile phone by VHV in which the mother can be involved as respondent is accepted.

The legacy of polio in Africa goes far beyond the tragedies of millions of children with permanent paralysis. It has a positive side, which includes the many well-trained polio staff who have vaccinated children, conducted surveillance, tested stool specimens in the laboratories, engaged with communities, and taken care of polio patients. This legacy also includes support for routine immunization services and vaccine introductions and campaigns for other diseases. As polio funding declines, it is time to take stock of the resources made available with polio funding in Africa and begin to find ways to keep some of the talented staff, infrastructure, and systems in place to work on new public health challenges. The partnerships that helped support polio eradication will need to consider funding to maintain and to strengthen routine immunization services and other maternal, neonatal, and child health programs in Africa that have benefitted from the polio eradication infrastructure.

In counteracting highly infectious and disruptive respiratory diseases such as COVID-19, vaccination remains the primary and safest way to prevent disease, reduce the severity of illness, and save lives. Unfortunately, vaccination is often not the first intervention deployed for a new pandemic, as it takes time to develop and test vaccines, and confirmation of safety requires a period of observation after vaccination to detect potential late-onset vaccine-associated adverse events. In the meantime, nonpharmacologic public health interventions such as mask-wearing and social distancing can provide some degree of protection. As climate change, with its environmental impacts on pathogen evolution and international mobility continue to rise, highly infectious respiratory diseases will likely emerge more frequently and their impact is expected to be substantial. How quickly a safe and efficacious vaccine can be deployed against rising infectious respiratory diseases may be the most important challenge that humanity will face in the near future. While some organizations are engaged in addressing the World Health Organization's "blueprint for priority diseases", the lack of worldwide preparedness, and the uncertainty around universal vaccine availability, remain major concerns. We therefore propose the establishment of an international candidate vaccine pool repository for potential respiratory diseases, supported by multiple stakeholders and countries that contribute facilities, technologies, and other medical and financial resources. The types and categories of candidate vaccines can be determined based on information from previous pandemics and epidemics. Each participant country or region can focus on developing one or a few vaccine types or categories, together covering most if not all possible potential infectious diseases. The safety of these vaccines can be tested using animal models. Information for effective candidates that can be potentially applied to humans will then be shared across all participants. When a new pandemic arises, these pre-selected and tested vaccines can be quickly tested in RCTs for human populations.
RESUMO
BACKGROUND: With the gradual roll-out of antiretroviral therapy (ART) to delay progression of HIV disease in children in programmes across sub-Saharan Africa and resource-limited settings elsewhere, reliable information on the number of vertically infected children eligible for such treatment is urgently required. METHODS: We present a model to estimate the number of vertically HIV-infected children by age who have progressed to moderate to severe disease (MSD) and as such are eligible for ART on the basis of clinical disease, allowing for: antenatal HIV prevalence, use of interventions to prevent mother-to-child transmission (PMTCT), infant feeding policies and availability of co-trimoxazole to prevent opportunistic infections that may hasten the onset of serious disease. The model assumptions were informed by published evidence and expert opinion; rates of progression to serious disease were inferred from mortality of infected and uninfected children of HIV-infected mothers; and mortality among children treated with ART was based on a study of treated children in Abidjan. To allow widespread use the model has been developed using the Excel spreadsheet software. RESULTS: With South Africa as a hypothetical example, published antenatal prevalence and demographic data, and assuming PMTCT coverage with single dose nevirapine of 11%, all exposed and infected children receive co-trimoxazole, and various infant feeding policy scenarios, estimated numbers of children eligible for ART are presented. CONCLUSIONS: This model is easy to implement and flexible and can be used in ART programmes at national and local level.

A systematic literature review was conducted to assess the effectiveness of strategies to improve community case management (CCM) of malaria. Forty-three studies were included; most (38) reported indicators of community health worker (CHW) performance, 14 reported on malaria CCM integrated with other child health interventions, 16 reported on health system capacity, and 13 reported on referral. The CHWs are able to provide good quality malaria care, including performing procedures such as rapid diagnostic tests. Appropriate training, clear guidelines, and regular supportive supervision are important facilitating factors. Crucial to sustainable success of CHW programs is strengthening health system capacity to support commodity supply, supervision, and appropriate treatment of referred cases. The little evidence available on referral from community to health facility level suggests that this is an area that needs priority attention. The studies of integrated CCM suggest that additional tasks do not reduce the quality of malaria CCM provided sufficient training and supervision is maintained.

A growing number of countries are moving to scale up interventions for prevention of mother-to-child transmission (PMTCT) of HIV in maternal and child health services. Similarly, many are working to improve access to paediatric HIV treatment. This paper reviews national programme data for 2004-2005 from low- and middle-income countries to track progress in these programmes. The attainment of the UNGASS target of reducing HIV infections by 50% by 2010 necessitates that 80% of all pregnant women accessing antenatal care receive PMTCT services. In 2005, only seven of the 71 countries were on track to meet this target. However PMTCT coverage increased from 7% in 2004 (58 countries) to 11% in 2005 (71 countries). In 2005, 8% of all infants born to HIV positive mothers received antiretroviral prophylaxis for PMTCT, up from 5% in 2004, though only 4% received cotrimoxazole. 11% of HIV positive children in need received antiretroviral treatment in 2005. In 31 countries that had data, 28% of women who received an antiretroviral for PMTCT also reported receiving antiretroviral treatment for their own health. Achieving the UNGASS target is possible but will require substantial investments and commitment to strengthen maternal and child health services, the health workforce and health systems to move from pilot projects to a decentralised, integrated approach.

Approximately 700,000 children become newly infected with HIV annually, mainly through mother-to-child transmission (MTCT), making paediatric HIV a leading cause of morbidity and mortality worldwide. The substantial interest in preventing MTCT (PMTCT) has generated information on rates of transmission and associated factors, but there is a lack of information on disease progression and mortality in vertically-infected children, especially from resource-poor settings. Peer-review journals with titles or abstracts containing reference to the review's themes were selected using widely available search engines. We review relevant literature on mortality in children born to HIV infected mothers; morbidity and mortality associated with paediatric HIV infections; eligibility to and efficacy of antiretroviral therapy (ART). Child mortality is independently associated with maternal HIV status and maternal death, with paediatric infection resulting in approximately 4 fold increase in mortality by age 2 years. Morbidities seen in infected children were similar to those seen in uninfected children, although the rates and recurrences of illness were greater. There is some evidence that progression to AIDS may be more rapid in resource poor settings, although data on this are very limited. PMTCT and paediatric ART have been shown to be highly successful in resource-limited settings, but are not universally applied. Further efforts to increase coverage of both PMTCT and paediatric ART could substantially reduce the numbers of children becoming infected and improve survival of those infected. Additionally, improvements in health infrastructures could improve care provision, not only through improved detection and monitoring but also through treatment of co-morbidities and nutritional support.
