With unprecedented speed, multiple vaccines against SARS-CoV-2 are available 1 year after the COVID-19 pandemic was first identified. As we push to achieve global control through these new vaccines, old challenges present themselves, including cold-chain storage, logistics of mass vaccination, and vaccine hesitancy. Understanding how much hesitancy toward might occur what factors may be driving concerns can improve ability public health workers communicators maximize uptake. We nested a...
A coordinated response to HIV/AIDS remains one of the 'grand challenges' facing policymakers today. Global health initiatives (GHIs) have potential both facilitate and exacerbate coordination at national subnational level. Evidence effects GHIs on is beginning emerge but has hitherto been limited single-country studies broad-brush reviews. To date, no study provided a focused synthesis systems across multiple countries. address this deficit, we review primary data from seven country three...
Considerable attention has been given by policy makers and researchers to the human resources for health crisis in Africa. However, little paid quantifying facility-level trends worker numbers, distribution workload, despite growing demands on workers due availability of new funds HIV/AIDS control scale-up. This study analyses reports HIV non-HIV ambulatory service workloads clinical staff urban rural district level facilities. Structured surveys facility managers, services covering 2005-07...
Much of the debate as to whether or not scaling up HIV service delivery in Africa benefits non-HIV priority services has focused on use nationally aggregated data. This paper analyses and presents routine health facility record data show trend correlations across services. Review district office client records for 39 facilities three districts Zambia, covering four consecutive years (2004-07). Intra-facility were conducted, coverage trends assessed rank between measured compare within...
Introduction Despite gains in global coverage of childhood vaccines, many children remain undervaccinated. Although mass vaccination campaigns are commonly conducted to reach these their effectiveness is unclear. We evaluated the a campaign reaching zero-dose children. Methods prospective study 10 health centre catchment areas Southern province, Zambia November 2020. About 2 months before national measles and rubella by Ministry Health, we used aerial satellite maps identify built...
The World Health Organization's health report 2006: Working together for underscores the importance of human resources health. shortage trained professionals is among main obstacles to strengthening low-income countries' systems and scaling up HIV/AIDS control efforts. Traditional practitioners are increasingly depicted as key prevention care. An appropriate effective response crisis requires reconsideration collaboration between traditional biomedical providers (THPs BHPs). aim this paper...
In Lusaka, where human immunodeficiency virus seroprevalence in young adults is ∼25%, four townships were studied to establish the prevalence of persistent diarrhea and etiologic importance cryptosporidiosis with diarrhea. Cryptosporidium parvum oocyst contamination urban water supplies was measured results used categorize these populations into high or low exposure. total, 506 reported as having had 2 weeks prior survey; 101 episodes persistent.

Abstract Nested serosurveys within routine service delivery platforms such as planned supplemental immunization activities (SIAs) provide an opportunity to collect information that can be used answer valuable questions on the effectiveness and efficiency of model inform future activities. However, integrating research data collection in SIAs is rarely done due concerns it will negatively impact program. We conducted a serosurvey nested November 2020 measles-rubella SIA integrated with Child...
Abstract Post-campaign coverage surveys estimate the number and proportion of previously unvaccinated children vaccinated during a supplementary immunization activity (SIA) but cannot address whether susceptible seronegative to measles rubella viruses were SIA. We conducted cross-sectional serosurvey nested within November 2020 measles-rubella SIA in Zambia. Children aged 9 months 5 years systematically sampled at 30 sites Choma Ndola Districts.

Approximately 62,000 Zambian children are living with HIV. HIV care and treatment is generally more limited in rural areas, where a heavy reliance on rain-fed subsistence agriculture also places households at risk of food water insecurity. We nested mixed methods study an explanatory sequential design clinical cohort adolescents (CHIV) Zambia. used validated questionnaires to assess household insecurity examined associations between indicators derived from those scales, characteristics,...

Abstract Models of measles transmission can be used to identify areas high risk tailor immunization strategies. Estimates spatial connectivity derived from data such as mobile phone records, however it is not clear how this maps the movement children who are more likely infected. Using travel surveys across two districts in Zambia and national data, we compared estimates out-of-district for population captured child-specific surveys. We then evaluated impact unadjusted adjusted measures on...
