Coronavirus disease-19 vaccine uptake, willingness for vaccination, and associated Factors among chronic follow patients attending in the two comprehensive specialized hospitals of Bahir Dar, Ethiopia.

BACKGROUND: Even though the disease has spread throughout the world, with millions killed, global COVID-19 vaccination coverage remains low, particularly in developing countries. However, epidemiological data is lacking in the area. Hence, this study aimed to assess COVID-19 uptake, willingness for vaccination, and associated factors. METHOD: A hospital-based cross-sectional study was conducted from May 1 to June 30, 2022, among patients attending chronic follow-up clinics in the two comprehensive specialized hospitals in Bahir Dar. The total sample size was 423. Participants were selected by a systematic random sampling technique. Data was gathered using a pre-tested questionnaire and analyzed using SPSS version 23. A descriptive analysis was performed. A binary logistic regression analysis was done to assess the association between variables. Variables with a p-value < 0.05 in the multi-variable logistic regression with a 95% confidence interval were considered statistically significant. RESULTS: The analysis included 400 out of 423 participants, representing a 95% response rate. The COVID-19 vaccination uptake was 46.8%, while the acceptance was 60.5%. About 56% and 68% of the respondents had good knowledge and a favorable attitude, respectively. Elderly people were 2.7 times more likely to be vaccinated. Similarly, urban residents were 3.94 times more vaccinated. The probability of being vaccinated among respondents with good knowledge and favorable attitudes was 70% and 79%, respectively. The willingness for vaccination increased among those individuals with favorable attitudes (AOR: 1.82). Urban people were less likely to accept vaccination (AOR: 0.46). Some participants misunderstood that vaccination may aggravate their disease condition. CONCLUSION: The overall COVID-19 vaccine uptake and acceptance for vaccination were low compared to what was estimated by the WHO. Age, residence, knowledge, and attitude were associated with COVID-19 vaccine uptake and acceptance of vaccination. Besides, there was a high level of rumor about the status of the vaccine and risk factors. Hence, special emphasis is warranted to deliver centrally trusted information. Moreover, further nationwide studies are warranted in the future.

Genetic diversity and distribution of noroviruses among all age groups of patients with diarrhea in Amhara National Regional State, Ethiopia.

BACKGROUND: Norovirus (NoV) is the leading cause of diarrheal disease worldwide and the impact is high in developing countries, including Ethiopia. Moreover, there is a significant and fluctuating global genetic diversity that varies across diverse environments over time. Nevertheless, there is a scarcity of data on the genetic diversity of NoV in Ethiopia. OBJECTIVE: This study was aimed to assess the genetic diversity and distribution of NoVs circulating in the Amhara National Regional State, Ethiopia, by considering all age groups. METHODS: A total of 519 fecal samples were collected from diarrheal patients from May 01/2021 to November 30/ 2021. The fecal samples were screened for the presence of NoVs using real-time RT-PCR by targeting a portion of the major capsid protein coding region. The positive samples were further amplified using conventional RT-PCR, and sequenced. RESULTS: The positivity rate of NoV was (8.9%; 46/519). The detection rate of NoV genogroup II (GII) and genogroup I (GI) was 38 (82.6%) and 8 (17.4%), respectively. Overall, five distinct GII (GII.3, GII.6, GII.10, GII.17, and GII.21) and two GI (GI.3 and GI.5) genotypes were detected. Within the GII types, GII.3 was the predominant (34.2%) followed by GII.21 (15.8%), GII.17 (10.5%), GII.6 and GII.10 each (2.6%). Norovirus GII.21 is reported for the first time in Ethiopia. The genetic diversity and distribution of NoVs were significantly different across the four sampling sits and age groups. The phylogenetic analysis revealed close relatedness of the current strains with published strains from Ethiopia and elsewhere. CONCLUSION: The distribution and genetic diversity of NoV was considerably high, with predominance of non-GII.4 genotypes. The GII.21 genotype is a new add on the growing evidences on the genetic diversity of NoVs in Ethiopia. Future nationwide surveillance studies are necessary to gain comprehensive data in Ethiopia.

Application of individual behavioral models to predict willingness to use modern contraceptives among pastoralist women in Afar region, Northern Ethiopia.

BACKGROUND: Use of modern contraceptive methods reduces the risk of unwanted pregnancy, and is influenced by individual-level factors. Willingness to use modern contraceptive methods maybe a useful metric when considering health outcomes as it could predict health behaviors. Therefore, the current study aimed to assess the willingness of women to use modern contraceptives in Afar pastoralist communities. METHODS: A community-based cross-sectional study was conducted from May 1 to 30, 2016. Three hundred forty-five women of childbearing age (15-49 years) were systematically sampled with proportionate allocation from seven randomly selected kebeles (neighborhoods) in Aballa District of Afar Region, Ethiopia. All women meeting the inclusion criteria in each selected household were interviewed at home using a semi-structured questionnaire. Construct validity was assured using factor analysis. A combination of individual behavioral models were applied in order to measure willingness to use modern contraceptive methods. Multiple logistic regressions were utilized to identify factors associated with willingness to use contraceptive at P-value of less than 0.05. RESULTS: Three hundred twenty-two women participated in the study, for a response rate of 93.3%. The mean age of respondents was 27 (±6) years. About one-third (N = 106, 32.9%) of the participants reported that they were willing to use modern contraceptives. Orthodox Christians (AOR = 4.22, 95% CI 1.94-8.92), women aged 19 or older at first marriage (AOR = 2.89, 95% CI 1.16-7.23), and women who had never experienced a stillbirth (AOR = 3.85, 95%CI 1.37-10.78) were more likely to report being willing to use modern contraceptives. Additionally, perceived severity of an unwanted pregnancy (AOR = 1.71, 95% CI 1.57-1.93) and perceived self-efficacy to use contraceptives (AOR = 1.26, 95% CI 1.17-1.65) were positively associated with the willingness. Women who had never had an abortion were less likely to express willingness to use modern contraceptives (AOR = 0.41, 95% CI 0.19-0.92) and perceived importance of cultural and religious norms (AOR = 0.85, 95% CI 0.62-0.90) was also negatively associated with willingness. CONCLUSIONS: The majority of women in this study were not willing to use modern contraceptive methods. A previous pregnancy outcome of stillbirth was associated with reduced willingness, while a prior abortion was associated with increased willingness. Perceived severity of unwanted pregnancy and higher self-efficacy surrounding contraceptive use were strong predictors of increased willingness to use contraceptives. Religious and cultural norms also appear to influence perception towards modern contraception. Thus, involvement of cultural and religious leaders and consideration of a woman's reproductive history are recommended when designing health education messages on contraception for Afar pastoralist women.

Seroprevalence and transmission of Hepatitis B virus among delivering women and their new born in selected health facilities, Addis Ababa, Ethiopia: a cross sectional study.

BACKGROUND: Hepatitis B Virus is a major public health problem worldwide. In 2012 alone, over 350 million chronic carriers and 1. 2 million annual deaths were occurred. Hepatitis B Virus causes 60 to 80% of the world's primary liver cancer and nearly 90% infants infected due to vertical transmission are at higher risk of developing chronic liver disease and cancer. Hence determining the burden of maternal and neonatal Hepatitis B Virus infection is a priority. METHODS: A cross sectional study was conducted from July - September 2012 at St. Paul's Hospital Millennium Medical College and Selam Health Center, Addis Ababa, Ethiopia. Blood samples from delivering mothers (n = 265) and their corresponding cords (n = 265) were collected. A pretested questionnaire was used to collect data. Hepatitis B Virus surface antigen was detected using Enzyme Linked Immunosorbent Assay. Frequency analysis and logistic regression test was used to identify the potential risk factors associated with Hepatitis B Virus positivity using SPSS Version -15. RESULTS: A total of 265 delivering women with the mean age of 25.8 years were enrolled in the study. Of these delivering women, 8 (3.0%) of mothers were positive for Hepatitis B Virus surface antigen, whereas 6 (2.3%) of cord bloods were positives with 75% concordance rate of exposed infants with sero-positive mothers. However, only one maternal positive case was observed for Hepatitis B e Ag test. Only 11% of the mothers know their Hepatitis B Virus status. Of the total mothers assessed for possible risk factors, 69 (26%) had only one type, while 161 (60.8%) had multiple exposure factors such as ear pricing, history of tribal marks, abortion, multiple-sexual partner and history of surgical procedures experienced from high to low frequency. The remaining 35 (13.2%) of the participants had not experienced possible risk factors. CONCLUSION: Though the maternal positivity rate was low, the rate of positivity in cord bloods was almost equal to those infected mothers. Therefore, screening of pregnant mothers and vaccination of infants could help to reduce the transmission. To minimize the higher overall risk exposure status of mothers, increasing awareness and intensive public health education is also recommended.
