This study aimed to determine the prevalence of EBV infection among pregnant women attending Cottage Hospital in Ilorin. A total of 45 pregnant women were tested, and questionnaires were administered to volunteer subjects after obtaining their informed consent. Approximately 5 ml of blood was aseptically collected via venous puncture from the antecubital fossa and dispensed into EDTA containers. Plasma was separated after centrifugation of the blood, and the obtained plasma was screened for anti-EBV IgG antibodies using ELISA techniques. Results revealed that 43 subjects (95.69%) tested positive for EBV, while 2 (4.4%) tested negative. Among different age groups, women aged 19-20, 26-30, and 36-40 showed a prevalence rate of 100%, with the lowest prevalence of 88.8% recorded among the 31-35 age group. Regarding the pregnancy stage, 100% was seen among first-trimester participants, while the lowest prevalence of 92.3% was noted during the third trimester. The majority of respondents were married, with those from polygamous families and single individuals showing a prevalence of 100%. Participants with primary and secondary education levels displayed the highest prevalence, while those with tertiary education had the lowest. Muslims had the highest prevalence, whereas Christians had the lowest. Moreover, regarding occupation, the unemployed, artisans, and students had the highest prevalence, while civil servants and businesswomen had the lowest prevalence. In conclusion, the results from this study highlight a notable prevalence of EBV (IgG) antibodies among pregnant women. These outcomes emphasize the necessity of raising awareness in the community about the implications of EBV infection and the Significance of maintaining proper personal hygiene to mitigate the chances of infection and spread","PeriodicalId":506326,"journal":{"name":"UMYU Scientifica","volume":" 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141368203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The non-linear formulated equations that govern the flow are resolved by a semi-analytical approach. The consequences of the numerous governing controlling parameters embedded in the formulated model is thoroughly described with the use of illustrative plots. It is noteworthy to report that raising the levels of Frank–Kamenetskii, sustentation, and thermo-diffusion parameters increases fluid velocity whereas reducing the radial magnetic field effect weakens the fluid flow. Additionally, it is significant to report that the sheer stress on the annular walls can be effectively regulated by applying appropriate values of magnetic number. In conclusion, the variations of the key parameters in this study can be used more effectively to control heat transfer and fluid flow using an annular geometry.
