Knowledgeable antenatal care as a pathway to skilled delivery: modelling the interactions between use of services and knowledge in Zambia.

Abstract: The link between antenatal care (ANC) and facility delivery is a specific example of the effect of early medical contacts on later use of essential services. The role of ANC in improving maternal health remains unclear. High levels of ANC are reported in a number of countries where skilled delivery remains uncommon. ANC may influence the use of services by increasing willingness to use services and educating about maternal health. The objective of this study is to understand the interaction between use of skilled and unskilled ANC, knowledge of obstetric complications and danger signs, and the eventual use of a facility for delivery. The study makes use of data from a survey of around 1700 women who had recently given birth across 11 districts of Zambia in 2011. Multivariate analysis is used to explore the associations between ANC use, knowledge and place of delivery. The results suggest that place of care and number of visits is strongly associated with the eventual use of a facility for delivery; an effect that is stronger in remote areas. Both skilled and unskilled ANC and obstetric knowledge is linked to higher use of facility delivery care while care provided at home appears to have an opposite effect. The research suggests that ANC influences later use of delivery care in two ways: by developing a habit to use formal care services and in increasing maternal knowledge. The work might be generalized to other health seeking behaviour to explore how the quantity and quality of initial contacts influence later use of services.

Human borreliosis caused by a New World relapsing fever Borrelia-like organism in the old world.

Abstract: Background Relapsing fever is an infectious disease previously neglected in Africa, which imposes a large public health burden in the country. We aimed to investigate and report on a case of relapsing fever borreliosis in Zambia. Methods A previously unknown Borrelia species was isolated from the blood of a febrile patient. Investigations of the presumptive vector ticks and natural hosts for the Borrelia species were conducted by culture isolation and/or DNA detection by Borrelia-specific polymerase chain reaction. Using culture isolates from the patient and bat specimens, genetic characterization was performed by multilocus sequence analysis based on the draft genome sequences. Results The febrile patient was diagnosed with relapsing fever. The isolated Borrelia species was frequently detected in Ornithodoros faini (n = 20/50 [40%]) and bats (n = 64/237 [27%]). Multilocus sequence analysis based on a draft genome sequence revealed that the Borrelia species isolates from the patient and presumptive reservoir host (bats) formed a monophyletic lineage that clustered with relapsing fever borreliae found in the United States. Conclusions A febrile illness caused by a Borrelia species that was treatable with erythromycin was identified in Zambia. This is the first study to report on relapsing fever Borrelia in Zambia and suggesting the likely natural reservoir hosts of the isolated Borrelia species. Interestingly, the isolated Borrelia species was more closely related to New World relapsing fever borreliae, despite being detected in the Afrotropic ecozone.
