Early-evening indoor and outdoor foraging by major malaria vectors in Nchelenge, Zambia
Despite a decade of indoor residual spraying, malaria remains holoendemic in Nchelenge District in northern Zambia. This study examined the hypothesis that the intransigence of malaria in Nchelenge District is due in part to early evening and outdoor foraging of local anopheline species. Three replicate collections were performed at 24 households using CDC light traps over 6 weeks during the dry season of 2019. Traps were set indoors, in animal p…
Implementation outcomes of 1-3-7 focus investigation for malaria in a low transmission setting in Southern Province, Zambia
Eleven countries have been certified as malaria free since 2016, but none of these are in subSaharan Africa where elimination challenges are unique. The 1-3-7 focus investigation approach is an implementation strategy that requires case reporting, case investigation/classification, and focal classification/response to be completed one, three, and seven days, respectively, after index case diagnosis. Real-time short-messaging-service reports are s…
Comparing and integrating human mobility data sources for measles transmission modeling in Zambia
Quantifying population mobility is crucial in developing accurate models of infectious disease dynamics. Increasingly, multiple data sources are available to describe individual and population mobility in a single location; however, there are no methods to systematically integrate these data. Combining information from these data sets may be valuable and help mitigate inherent biases in each data set due to sampling, censoring, and recall. We exa…
Covid-19 vaccine coverage among adults in Sarlahi District of Nepal in 2022
Nepal launched its COVID-19 vaccination campaign in January 2021 through the COVID-19 Vaccines Global Access (COVAX) facility. Vaccine coverage, especially in low- and middle-income countries (LMICs), is measured using administrative-level data; however, this source is often subject to biases and limitations. We conducted a household survey in rural Sarlahi District, Nepal, to estimate COVID-19 vaccine coverage and assess associations with partic…
High measles and rubella vaccine coverage and seroprevalence among Zambian children participating in a measles and rubella supplementary immunization activity
Post-campaign coverage surveys estimate the proportion of previously unvaccinated children vaccinated during supplementary immunization activities (SIA) but cannot address whether susceptible children seronegative to measles and rubella viruses were vaccinated during the SIA. We conducted a cross-sectional serosurvey nested within the November 2020 measles-rubella SIA in Zambia, systematically sampling children aged 9 months to 5 years at 30 SIA …
Feasibility and acceptability of collecting dried blood spots (DBS) from children after vaccination during supplementary immunization activities to estimate measles and rubella seroprevalence
Nested serosurveys within routine service delivery platforms such as planned supplemental immunization activities (SIAs) provide an opportunity to collect information that can be used to answer valuable questions on the effectiveness and efficiency of the delivery model to inform future activities. However, integrating research data collection in SIAs is rarely done due to concerns it will negatively impact the program. We conducted a serosurvey …
Who is missed in a community-based survey
Community-based serological studies are increasingly relied upon to measure disease burden, identify population immunity gaps, and guide control and elimination strategies; however, there is little understanding of the potential for and impact of sampling biases on outcomes of interest. As part of efforts to quantify measles immunity gaps in Zambia, a community-based serological survey using stratified multi-stage cluster sampling approach was co…
Changes in healthcare seeking behaviors among caretakers of children in the previously occupied Isis territory
This study provides insight into health seeking challenges among the many individuals who remained in Hadeetha during the ISIS occupation. Health use patterns by provider type mirror the concerns the healthcare providers shared: limited availability, efflux of professional workers, limited resources and security challenges to providing care. Positive trends toward increased access to physicians during periods of peace are an encouraging marker fo…
An evaluation of the early impact of the Covid-19 pandemic on Zambia’s routine immunization program
Implications of the COVID-19 pandemic for both populations and healthcare systems are vast. In addition to morbidity and mortality from COVID-19, the pandemic also disrupted local health systems, including reductions or delays in routine vaccination services and catch-up vaccination campaigns. These disruptions could lead to outbreaks of other infectious diseases that result in an additional burden of disease and strain on the healthcare system. …
Novel bioinformatic methods and machine learning approaches reveal candidate biomarkers of the intensity and timing of past exposure to Plasmodium falciparum
Accurately quantifying the burden of malaria over time is an important goal of malaria surveillance efforts and can enable effective targeting and evaluation of interventions. Malaria surveillance methods capture active or recent infections which poses several challenges to achieving malaria surveillance goals. In high transmission settings, asymptomatic infections are common and therefore accurate measurement of malaria burden demands active sur…
Using geospatial models to map zero-dose children
INTRODUCTION: Despite gains in global coverage of childhood vaccines, many children remain undervaccinated. Although mass vaccination campaigns are commonly conducted to reach these children their effectiveness is unclear. We evaluated the effectiveness of a mass vaccination campaign in reaching zero-dose children. METHODS: We conducted a prospective study in 10 health centre catchment areas in Southern province, Zambia in November 2020. About 2 …
Archaeological Practice in Québec City, a Unesco World Heritage City
A arqueologia é conhecida como ferramenta de desenvolvimento econômico assim como meio de engajamento social. O nível municipal está sendo, cada vez mais, visto como o meio privilegiado para a proteção do patrimônio cultural arqueológico e a participação cidadã. Enquanto sitio do patrimônio mundial da UNESCO, a cidade de Quebec desenvolveu uma abordagem conectando governança e participação publica, assim como legislação e prática. O programa arqu…
Postnatal care utilization and local understandings of contagion among HIV-infected and uninfected women in rural, southern Zambia
Postnatal care is essential for ensuring the optimal health of newborns and necessary for the prevention of maternal-to-child human immunodeficiency virus (HIV) transmission as well as the early diagnosis and treatment of HIV-infected infants. However, coverage of postnatal care is low in many rural areas of sub-Saharan Africa. We examined women's experiences of accessing formal postnatal care for their HIV-exposed newborns, comparing reports of …

Measles vaccination coverage estimates from surveys, clinic records, and immune markers in oral fluid and blood
Measles IgG antibodies in OF was not a suitable immune marker for monitoring measles vaccination coverage in this setting. Because agreement between conventional MCV1 indicators was mediocre, immune marker surveillance with blood samples could be used to validate conventional MCV1 indicators and generate adjusted results that can be compared across indicators
Neonatal survival interventions in humanitarian emergencies
Neonatal care is provided by most of the responding humanitarian organizations; however, the quality, breadth and consistency of this care are limited
Incidence and risk factors for malaria, pneumonia and diarrhea in children under 5 in UNHCR refugee camps
As in stable settings, pneumonia and diarrhea are important causes of mortality among refugee children. Malaria remains a significant cause of child mortality in refugee camps in Africa and will need to be addressed as part of regional malaria control and elimination efforts. Little is known of neonatal morbidity and mortality in refugee settings, and neonatal deaths are likely to be under-reported. Global measles control efforts have reduced the…
The burden of malaria in post-emergency refugee sites
These findings represent one of the most extensive reports on malaria among refugees in post-emergency sites. Despite declines in malaria incidence among refugees in several countries, malaria remains a significant cause of mortality among children younger than five years of age. Further progress in malaria control, both within and outside of post-emergency sites, is necessary to further reduce malaria incidence and mortality among refugees and a…
Foundations for effective strategies to control sexually transmitted infections
Achieving maximal benefit from clinic-based, sexually transmitted infection (STI) control strategies requires that persons seek treatment at public clinics. Community-based, ethnographic research methods were used to examine patterns of health-seeking behavior for sexually transmitted infections in western Kenya. Illness narratives of sexually transmitted infections provided the basis for an analysis of sequential steps in health-seeking behavior…
