Acceptance of COVID-19 vaccine and associated factors among healthcare workers in Katsina state: a cross-sectional study in Northwest Nigeria.

OBJECTIVES: Healthcare workers were prioritised to receive the COVID-19 vaccine in Nigeria. Administration of COVID-19 vaccination in Nigeria was challenging because of a lack of trust in vaccine safety and vaccine effectiveness among healthcare workers, who are expected to provide reliable information about vaccines and vaccine-preventable diseases in the communities. Hence, their acceptance and attitudes towards COVID-19 preventive practices could influence the acceptance of the vaccine by the local population. This cross-sectional study assessed the acceptance of the COVID-19 vaccine among healthcare workers in Katsina State. We predicted the variables that increased the vaccine acceptance using logistic regression analysis. SETTING: This hospital-based study was conducted at primary, secondary and tertiary healthcare facilities in Nigeria. PARTICIPANTS: A total of 793 healthcare workers were included in this study. Of these, 65.4% (n=519) were male. OUTCOME MEASURES: To assess acceptance of COVID-19 vaccine measures, and factors increasing acceptance among healthcare workers. RESULTS: Of the healthcare workers, 80% (638) were tested for the SARS-CoV-2, of whom 10.8% (n=65) tested positive. Approximately 97% (n=765) of them believed that the COVID-19 vaccine was safe, and 90% (n=714) received the first dose of the vaccine. Healthcare workers between 30 and 39 years were more likely to accept the vaccine (aOR: 7.06; 95% CI 2.36 to 21.07; p<0.001). Those who had been tested for COVID-19 were more likely (aOR:7.64; 95% CI 3.62 to 16.16; p<0.001) to accept the vaccine. CONCLUSIONS: Our findings showed that the age and prior COVID-19 testing were the main factors influencing the acceptance of the COVID-19 vaccine. There was high acceptance of the COVID-19 vaccine among healthcare workers in Katsina State, Nigeria. Future studies should focus on the completion of doses and serological testing for immunity.

Impact of climatic variables on childhood severe malaria in a tertiary health facility in northern Nigeria.

Introduction: Despite the recent progress in the malaria burden, climatic factors are important if the world will achieve the set target of its eradication. Hence, this study determined the impact of climatic conditions on childhood severe malaria in a tertiary health facility in northern Nigeria. Methodology: This was a retrospective descriptive study that involved children with severe malaria managed between July 2016 and August 2017. The diagnosis of severe malaria was according to the World Health Organization 2015 guidelines. We extracted relevant data from case records and obtained the weather information from the Nigerian Meteorological Agency and www.worldweatheronline.com. Data were entered in Microsoft Excel 2013 and analyzed with Statistical Package for the Social Sciences version 20. Results: A total of 483 cases of children with severe malaria were managed. The median age was 4.0 (2.5-8.0) years. Males were 261 (54.0%). In the wet season, 375 (77.6%) cases were recorded, while 108 (22.4%) cases occurred during the dry season. The odds of malaria occurring during the wet season were 2.057 (95% CI, 1.613-2.622). Temperature patterns were not related to malaria cases. Malaria cases showed significant moderate positive cross-correlation at 2- and 3-months lag for the rainfall pattern (best cross-correlation occurred at 3 months lag with a coefficient of 0.598, p = 0.045). Conclusion: This study demonstrated marked seasonality of childhood severe malaria infection with 77% of cases during the wet season. Malaria was associated with only rainfall at a 2 to 3 months lag amongst the climatic variables. We recommend the urgent implementation of seasonal malaria chemoprophylaxis.

Determinants of health-related quality of life among human immunodeficiency virus positive (HIV-positive) patients at Ahmadu Bello University teaching hospital, Zaria, Nigeria- 2015.

BACKGROUND: The advent of Highly Active Antiretroviral Therapy (HAART) is associated with improved clinical and laboratory outcomes resulting in prolonged life and well-being of people living with Human Immunodeficiency Virus (PLHIV). However, the needs for life-long therapy, medications' side effects and stigma have raised concerns about their quality of life (QOL). This study assessed the determinants of Health-related quality of life (HRQOL) among HIV-positive patients at Ahmadu Bello University Teaching Hospital (ABUTH) Zaria. METHODS: We conducted a cross-sectional study of 353 HIV-positive adults on HAART attending the HIV clinic of ABUTH, Zaria. The participants were recruited into the study using a systematic sampling technique. Data on socio-demographics, medical parameters, QOL and family functionality were collected using structured, interviewer-administered questionnaire. The World Health Organization (WHO) Quality of Life HIV short form instrument (WHOQOL-HIV BREF) item and Family APGAR tool were respectively used in assessing the QOL and family functionality of the participants. We performed univariate, bivariate and multivariate analysis. RESULTS: Mean age was 39.1(±10.9) years, 239 (67.7%) were females, 208 (58.9%) were Hausa-Fulani, 240 (68.2%) married and up to 210 (59.4%) had at least a secondary education. The overall mean scores on the scale of 4-20 for HRQOL were similar in three domains: environment domain 14.5(±2.8); social relationship 14.4(±3.1) and level of independence 14.4(±2.5). Lower scores were recorded in spirituality/religion/personal beliefs 12.3(±4.3). Identified determinants of HRQOL were spousal HIV- positive status (AOR = 3.37; CI; 1.46-7.74) and high family function (AOR = 2.57; CI: 1.51-4.39). CONCLUSION: Having highly functional family and having HIV-positive partner were the major determinants of HRQOL. Routine family counselling and strengthening the HIV social-support network should be incorporated into the routine patients' care in HIV treatment centers.
