Factors associated with uptake of postpartum family planning services in Dodoma City Council, Tanzania: A cross-section study

Background: Postpartum family planning is very essential to mothers’ health. However, its utilization remains low in developing countries. Objective: To determine the proportion and factors associated with uptake of PPFP services in Dodoma Tanzania. Methods: A cross-sectional study employing a quantitative approach was conducted among women who gave birth one year before the study period (June 2020) in Dodoma city council. A two-stage sampling technique was employed to recruit a total number of 209 participants. An interviewer-administered questionnaire was used to collect data. Data were entered and cleaned using Epi Info 7 and later exported to and analyzed using SPSS version 25.0. Bivariate and multiple logistic regression models were employed during data analysis. Odds ratios with 95% confidence intervals were computed to identify factors associated with postpartum family planning. Results: Majority (53.6%) of women used contraceptives within one year after delivery. Three factors were significantly associated with the uptake of postpartum family planning. Lower odds for uptake of PPFP were found among self-employed women (AOR: 0.5, 95% CI 0.25–0.74) and unemployed women (AOR: 0.2, 95% CI 0.05–0.31) when compared with employed women. Using community health fund insurance (AOR: 2.4, 95% CI 1.09–6.42) and National Health Insurance Fund (AOR: 2.7, 95% CI 1.54–5.99) as a mode of payments for health had higher odds for uptake of PPFP compared to cash mode. Women with an adequate number of antenatal care visits had higher odds (AOR: 2.9, 95% CI 1.24–6.89) of uptake of PPFP compared to women with an inadequate number of antenatal care visits. Conclusion: The uptake of PPFP among women was not adequate and was associated with being employed, being covered by health insurance and adequate antenatal care visits. More interventions are needed to enhance PPFP use among women

Prevention, detection, and response to anthrax outbreak in Northern Tanzania using one health approach: A case study of Selela ward in Monduli district

Background: Anthrax is an infectious fatal zoonotic disease caused by Bacillus anthracis. Anthrax outbreak was confirmed in samples of wild animals following rumors of the outbreak in wild animals, livestock, and humans in Selela ward, Monduli district of Northern Tanzania. Therefore, a multi-sectorial team was deployed for outbreak response in the affected areas. Objectives: The aim of the response was to manage the outbreak in a One Health approach and specifically: (i) To determine the magnitude of anthrax outbreak in humans, livestock, and wild animals in Selela ward, (ii) to assess the outbreak local response capacity, (iii) to establish mechanisms for safe disposal of animal carcasses in the affected areas, and (iv) to mount effective control and preventive strategies using One Health approach in the affected areas. Materials and Methods: This was a cross-sectional field survey using: (i) Active searching of suspected human cases at health facilities and community level, (ii) physical counting and disposal of wild animal carcasses in the affected area, (iii) collection of specimens from suspected human cases and animal carcasses for laboratory analysis, and (iv) meetings with local animal and human health staff, political, and traditional leaders at local levels. We analyzed data by STATA software, and a map was created using Quantum GIS software. Results: A total of 21 humans were suspected, and most of them (62%) being from Selela ward. The outbreak caused deaths of 10 cattle, 26 goats, and three sheep, and 131 wild animal carcasses were discarded the majority of them being wildebeest (83%). Based on laboratory results, three blood smears tested positive for anthrax using Giemsa staining while two wildebeest samples tested positive and five human blood samples tested negative for anthrax using quantitative polymerase chain reaction techniques. Clinical forms of anthrax were also observed in humans and livestock which suggest that wild animals may contribute as reservoir of anthrax which can easily be transmitted to humans and livestock. Conclusion: The rapid outbreak response by multi-sectoral teams using a One Health approach managed to contain the outbreak. The teams were composed of animal and human health experts from national to village levels to control the outbreak. The study testifies the importance of multi-sectoral approach using One Health approach in outbreak preparedness and response

Antimicrobial use, residues, resistance and governance in the food and agriculture sectors, Tanzania

All infections are potentially curable as long as the etiological agents are susceptible to antimicrobials. The increased rate at which antimicrobials are becoming ineffective is a global health risk of increasing concern that threatens withdrawal of beneficial antimicrobials for disease control. The increased demand for food of animal origin, in particular eggs, meat and milk has led to intensification and commercial production systems where excessive use and misuse of antimicrobials may prevail. Antimicrobials, handled and used by farmers and animal attendants with no formal education, may be predisposed to incorrect dosages, misuse, incorrect applications and non-adherence to withdrawal periods. This study was conducted to assess the regulatory roles and governance of antimicrobials, establish the pattern and extent of their use, evaluate the antimicrobial residues and resistance in the food animals and crop agriculture value chains, and relate these findings to existing strategies in place for combating the emergence of antimicrobial resistance in Tanzania. A multimethod approach (desk review, field study and interviews) was used. Relevant establishments were also visited. High levels of resistance to penicillin G, chloramphenicol, streptomycin and oxytetracycline have been reported, especially for Actinobacter pyogenes, Staphylococcus hyicus, Staphylococcus intermedius and Staphylococcus aureus from dairy cattle with mastitis and in humans. Similar trends were found in poultry where eggs and meat are contaminated with Escherichia coli strains resistant to amoxicillin + clavulanate, sulphamethoxazole and neomycin. An increasing trend of emerging multidrug resistant E. coli, Klebsiella pneumoniae, Staphylococcus aureus and Salmonella was also found in food animals. An increase in methicillin resistant Staphlococcus aureus (MRSA) and extended-spectrum beta-lactamase (ESBL) in the livestock sector in Tanzania have been reported. The pathogens isolated in animals were resistant to ampicillin, augmentin, gentamicin, co-trimoxazole, tetracycline, amoxicillin, streptomycin, nalidixic acid, azithromycin, chloramphenicol, tylosin, erythromycin, cefuroxime, norfloxacin and ciprofloxacin. An increased usage of antimicrobials for prophylaxis, and therapeutics against pathogens and for growth promotion in livestock, aquaculture and crop production were observed. A One Health strategic approach is advocated to combat antimicrobial resistance (AMR) in the food and agriculture sectors in Tanzania. Practical recommendations include (a) legislation review and implementation; (b) antimicrobial use (AMU), AMR and antimicrobial residue (AR) awareness and advocacy among stakeholders along the value chain; (c) strengthening of surveillance and monitoring programs for AMU, AMR and AR; (d) enhanced development and use of rapid and innovative diagnostic tests and the promotion of biosecurity principles; and (e) good husbandry practices. The utilization of this information to improve public health policies and reduce the burden of AMR will be beneficial.SUPPLEMENTARY MATERIAL: Table S1.

Environmental determinants influencing anthrax distribution in Queen Elizabeth Protected Area, Western Uganda

Bacillus anthracis, the bacteria that causes anthrax, a disease that primarily affects herbivorous animals, is a soil borne endospore-forming microbe. Environmental distribution of viable spores determines risky landscapes for herbivore exposure and subsequent anthrax outbreaks. Spore survival and longevity depends on suitable conditions in its environment. Anthrax is endemic in Queen Elizabeth Protected Area in western Uganda. Periodic historical outbreaks with significant wildlife losses date to 1950s, but B. anthracis ecological niche in the ecosystem is poorly understood. This study used the Maximum Entropy modeling algorithm method to predict suitable niche and environmental conditions that may support anthrax distribution and spore survival. Model inputs comprised 471 presence-only anthrax occurrence data from park management records of 1956–2010, and 11 predictor variables derived from the World Climatic and Africa Soil Grids online resources, selected considering the ecology of anthrax. The findings revealed predicted suitable niche favoring survival and distribution of anthrax spores as a narrow-restricted corridor within the study area, defined by hot-dry climatic conditions with alkaline soils rich in potassium and calcium. A mean test AUC of 0.94 and predicted probability of 0.93 for anthrax presence were registered. The five most important predictor variables that accounted for 93.8% of model variability were annual precipitation (70.1%), exchangeable potassium (12.6%), annual mean temperature (4.3%), soil pH (3.7%) and calcium (3.1%). The predicted suitable soil properties likely originate from existing sedimentary calcareous gypsum rocks. This has implications for long-term presence of B. anthracis spores and might explain the long history of anthrax experienced in the area. However, occurrence of suitable niche as a restricted hot zone offers opportunities for targeted anthrax surveillance, response and establishment of monitoring strategies in QEPA
