Enteric fever is an invasive bacterial infection mostly caused by Salmonella enterica serovar Typhi, which is a common agent of enteric fever. This illness has been a major public health issue, as it affects a large number of individuals globally. The box-plot analytic method is involved in exploratory data analysis using statistical techniques to identify patterns that may be hidden in a group of numbers used to visually summarize and compare groups of data. We evaluted the effect of enteric fever on various haematologic parameters using the box-plot distribution model. Samples were obtained from 400 volunteer patients as well as healthy subjects (controls). Assay for typhoid fever was carried out using obtained serum samples to detect specific O and H antigens. Antibody titres of 1:80 and higher for anti-TO and 1:160 and higher for anti-TH antibodies were taken as cutoff values to indicate recent infection of typhoid fever. The haematologic parameters were evaluated using an automated haematology analyser. A statistically significant decrease was observed in packed cell volume, white blood cell count, erythrocyte sedimentation rate and haemoglobin concentration, while a statistically insignificant difference was observed in the neutrophils, lymphocytes and monocytes seen in the box-plot distribution analysis. Typhoid fever causes significant haematologic changes which could be helpful in diagnosis. The box-and-whisker plots compared the distributions of the haematologic parameters, spread and overall ranges. Awareness of these parameters could be useful in providing accurate diagnosis and therapy, particularly in underresourced endemic regions in developing countries.

Background: Hepatitis B Virus (HBV) is a worldwide health issue and a source of major concern around the globe. Infections caused by hepatitis B virus pose a major challenge to public health. This study evaluates the prevalence and transmission rate of Hepatitis B Virus infection among children of primary school age at our study location. Method: Three hundred and three (303) volunteer subjects were screened.Structured questionnaire were administered to consenting participants to determine demographic and other risk factors for HBV infection.Samples obtained were analysed using a Laboratory-based immunoassay-HBsAg rapid diagnostic test (RDTs) in lateral flow assays formats. Sera samples obtained were stored at -20oc prior use. Results: Overall result showed that 46 (15.2%) were sero-positive for HBV infection. Considering age factor, Children aged 10 – 12 years showed a higher prevalence of 16(5.3%) [P-value 0.736; (P >0.05)]. Based on gender of subjects screened, a prevalence of 34(11.2%) was recorded among the males subjects compared to females with 12(4.0%) positivity, [(P < 0.05)]. Risk factors on family history recorded 13(4.3%) positivity, considering place of circumcision as risk factors among male subjects; result showed that subjects circumcised using traditional methods   recorded 17 (11.7%) positivity. [P-value 0.856 (P>0.05)].Respondents with history of cuts recorded a prevalence of 29(9.6%) positivity; [P-Value 0.362 (P>0.05)] considering enzyme assay of positive subjects, 13 (4.3%) subjects recorded an elevated Alanine transaminases. Conclusion: The transmission rate of HBV infection among the family members was found to be high in this study. This upsurge calls for an urgent vaccination of the population by relevant healthcare providers.
