Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infections lead to chronic diseases and are the most common causes of liver cirrhosis and cancer in developing countries like Nepal. The study is carried out to determine the seroprevalence of HBV and HCV by using a Rapid kit method and Elisa Method to find out its risk factors. The cross-sectional study was done among blood donating people from 16th August 2016 to 19th November 2016. Blood donors in Pokhara Valley were screened for anti-HCV antibodies, anti-HBV antibodies using third generation ELISA kits and automated ELISA Processor in serology laboratory at Central Blood Transfusion Service (CBTS) of Nepal Red Cross Society (NRCS) in Pokhara, Nepal. 1777 (87.2%) units were male blood donors and 260 (12.6%) units were female donors out of 2037 participants. Gender wise, the ratio between male and female was 1:0.1. HBV and HCV infection rate in blood donors were detected at 0.7% (15/2037) and 0.5% (8/2037) respectively. HBV infection rate in volunteer blood donor people was 0.7% (14/1881) which was higher than the replacement donors i.e. 0.6% (1/156). Similarly, in HCV infection rate in volunteer donor were 0.4% (8/1881). HBV infected people are detected higher than the HCV infected people among the blood donors. In addition, there was no significant relationship between positive results of HBV and HCV tests with the gender, age, tattoo, donor type.

Background & aims Kazakhstan has implemented comprehensive programs to reduce the incidence of Hepatitis B and Hepatitis C. This study aims to assess seroprevalence and risk factors for HBsAg and anti-HCV positivity in three large regions of Kazakhstan. Methods A cross-sectional study was conducted in three regions geographically remote from each other. Participants were randomly selected using a two-stage stratified cluster sampling and were surveyed by a questionnaire based on the WHO STEP survey instrument. Blood samples were collected for HBsAg and anti-HCV testing. Results A total of 4,620 participants were enrolled. The seroprevalence was 5.5% (95%CI: 3.6%-8.4%) for HBsAg and 5.1% (95%CI: 3.5%-7.5%) for anti-HCV antibodies. Both were more prevalent in the western and northern regions than in the southern. A history of blood transfusion was significantly associated with anti-HCV presence, with odds ratios (ORs) of 2.10 (95%CI: 1.37–3.21) and was borderline associated with HBsAg 1.39 (95%CI: 0.92–2.10), respectively. Having a family member with viral hepatitis was also borderline associated (2.09 (95%CI: 0.97–4.50)) with anti-HCV positivity. Conclusions This study found a high-intermediate level of endemicity for HBsAg and a high level of endemicity for anti-HCV antibodies in three large regions of Kazakhstan. We found that history of surgery was not associated with HbsAg neither with anti-HCV seropositivity rates. Blood transfusion was associated with anti-HCV seropositivity, however, to investigate effectiveness of the introduced comprehensive preventive measures in health care settings, there is a need to conduct further epidemiological studies.

Abstract Introduction: HCV is a blood borne viral infection transmitted mainly via blood and blood product transfusion. Children diagnosed with cancers are especially in the high-risk group for infection with blood transmissible infections like HCV because of their dependence on blood and blood product. Children with cancer are also exposed to unwholesome practice like scarification marks. Also children with cancer because of their immunocompromised state lack the ability effectively clear HCV after an acute infection, there are therefore very likely to have chronic infections.Because of the above reason it became necessary to determine the prevalence and risk factors for HCV infection among children with cancer at Lagos .Methods: We designed a descriptive cross-sectional study conducted over a 12 months period at the Oncology ward and outpatient clinics of LUTH.Result: 50 children with cancers were recruited age range 7 months and 17 years. Ninety percent of them has been exposed to blood transfusion while 32% and 18% of them has had surgery and scarification marks respectively. The most diagnosed cancer was ALL with 44%. And 82% of the subjects were on chemotherapy at the time of recruitment. The sero-prevalence of HCV infection among those with cancer was 0%.Conclusion: The sero-prevalence of HCV infection was zero percent despite significant exposure to blood transfusion and other risk factors.

<p>Introduction<strong>: </strong>Blood donation is necessary in order to maintain an adequate supply of blood to patients who are suffering from any kind of disease or trauma, which requires them to have blood transfusion. Female non-blood donors are generally low in number.<strong> </strong>Therefore, this research was carried out to assess the main reasons behind the lack of blood donations made by females, and their knowledge, attitude and perceptions towards voluntary blood donation.</p> <p>Methodology: A cross-sectional study was conducted on 664 female health professionals, who were selected by non-probability convenience sampling from two tertiary care hospitals. A pretested questionnaire was presented to the sample population, and the data was entered and analyzed on SPSS (V17).</p> <p>Results: 94.6 % were aware with the fact that blood is screened for AIDS, Hepatitis B and C before transfusion. Moreover, 83.7% said that they will only donate blood if a family, relative or friend would need it and similarly 83.4%  suggested that they would donate blood if blood donation camps are arranged in hospital premises. 81.8 % thought that blood donors can contract Hepatitis B after donation where as only 29.5% did not blood due already blood loss in menstrual cycle.<strong></strong></p> <p>Conclusion<strong>: </strong>The participants had adequate knowledge about the benefits of blood donation. The most important reason identified for not donating blood is the lack of facilities within the workplace or lack of approach by responsible authorities. The results of the study may help in minimizing the misconceptions of the participants about blood transfusion, which would increase their contribution towards blood donation.</p>

The main objective of the study was to determine the frequency of hepatitis B and hepatitis C in hemodialysis dependent patients who are positive for either type of hepatitis infection.Methodology:Study was conducted for duration of five months (1st Dec 2014- 23rd April 2015) at nephrology unit of Khyber teaching hospital and kidney center of Hayat Abad medical complex. Patients who were dependent on dialysis with renal failure due to any cause were targeted for the study. All patients who were found positive for either type of hepatitis infection were included in the study. All patients who were positive with hepatitis infection before the start of dialysis and those who came for the first time for dialysis were excluded from the study.A semi structured questionnaire with both open and close ended questions was used to collect the information from the patients. Written consent was taken from all the patients prior to the data collection after explaining purpose of the study. It was a cross sectional study and non-probability convenient sampling technique was adopted for the data collection. Total of hundred patients who were positive for hepatitis were taken as sample size. Patient’s record was also thoroughly checked as an adding tool for data collection. Apart from patients some inquiry was also done from the concerned staff working on dialysis machines.Results:Results of this study show that the prevalence of hepatitis infection is more in dialysis dependent patients as compared to the general population, and that among the positive cases the frequency of hepatitis C was more than hepatitis B. Common risk factors associated with increase prevalence of hepatitis infection among hemodialysis dependent patients are frequent blood transfusion without proper screening, lack of proper sterilization of dialysis machine and environment where dialysis is carried out. Close proximity of the patients with positive cases of hepatitis positive patients, previous surgical procedures carried out, history of hepatitis infection in family and decreased immunity of the dialysis patientsConclusions:Frequent dialysis leads to increase frequency of hepatitis C as compared to hepatitis B and unsterilized environment of the area around the machine and unscreened blood transfusion are the major contributors.

Background and ObjectiveThe improved performance of serological tests has significantly reduced the risk of human immunodeficiency and hepatitis B and C viruses transmission by blood transfusion, but there is a persistence of residual risk. The objective of this study was to evaluate the impact of multiplex PCR in reducing the risk of residual transmission of these viruses in seronegative blood donors in Burkina Faso.MethodsThis cross-sectional study was conducted from March to September 2017. The serological tests were performed on sera using ARCHITECTSR i1000 (Abbot diagnosis, USA). Detection of viral nucleic acids was performed by multiplex PCR on mini-pools of seronegative plasma for HBV, HCV and HIV using SaCycler-96 Real Time PCR v.7.3 (Sacace Biotechnologies). Multiplex PCR-positive samples from these mini-pools were then individually tested by the same method.Results A total of 989 donors aged 17 to 65 were included in the present study. "Repeat donors" accounted for 44.79% (443/989). Seroprevalences for HIV, HBV, and HCV were 2.53% (25/989), 7.28% (72/989) and 2.73% (27/989), respectively. Of the 14 co-infections detected, HBV/HCV was the most common with 0.71% (7/989) of cases. Of 808 donations tested by multiplex PCR, 4.70% (38/808) were positive for HBV while no donation was positive for HIV or HCV.Conclusion: Our study showed a high residual risk of HBV transmission through blood transfusion. Due to the high prevalence of blood-borne infections in Burkina Faso, we recommend the addition of multiplex PCR to serologic tests for optimal blood donation screening.

Background:The lack of a vaccine for Hepatitis C virus (HCV) places children at a high risk of contracting the infection. It becomes necessary to accurately diagnose this infection for proper treatment as well as identifying potential risk factors for effective management.Aim:This study was conceived to assess the test performance of the commonly used Immunochromatographic test (ICT) strip and identify the associated clinical manifestations and risk factors of HCV in children in Enugu Metropolis.Method:A cross-sectional study involving randomly selected 270 children below six years of age was conducted in Enugu Nigeria. The subjects were screened for anti-HCV by ICT and Enzyme-Linked Immunosorbent Assay (ELISA) and the demographic, signs and symptoms and risk factors were collected.Results:A total of 50 out of 270 children were positive for anti-HCV with a seropositivity of 18.5%. ICT strip had a very low sensitivity of 38.00% with an accuracy of 88.52% in detecting anti-HCV. The presence of dark urine was associated (p= 0.01) with HCV infection.Conclusion:A seroprevalence of 18.5% of Anti-HCV was found in children below six years old in Enugu metropolis and the performance of ICT in diagnosing HCV infection was poor compared to ELISA.

Background and Objectives: Trichinellosis, a serious and sometimes fatal human disease, is a foodborne zoonotic disease with worldwide distribution caused by parasitic nematodes of the genus Trichinella. Humans are infected with Trichinella larvae through the ingestion of meat that has not been properly cooked. Romania reported most of the confirmed cases of trichinellosis among the EU countries. The aim of this cross-sectional study was to evaluate, for the first time, the seroprevalence and risk factors of Trichinella infection in blood donors from Western Romania. Materials and Methods: Serum samples of 1347 consecutive blood donors were investigated using an immunoenzymaticassay (ELISA) for the determination of specific IgG class antibodies against T.spiralis. A questionnaire interview was used to obtain information regarding the potential risk factors associated with T. spiralis infection. Mantel–Haenszel chi-squared test or the Fisher exact two-tailed test, as appropriate, were used for comparison between T. spiralis positive and T. spiralis negative blood donors. Student’s t-test was used to evaluate differences between means in studied groups and body mass index was calculated by dividing weight in kilograms by height in meters squared. Statistical analysis was performed using Epi Info Version 7.2 and Stata 16.1. Results: T. spiralis IgG antibodies were detected in 2.00% (27) of 1347 consecutive blood donors. Eating raw and/or undercooked meat, from pigs or wild boars, was found to be the main risk factor (p < 0.001). Strong alcoholic drink consumption was highly associated with T. spiralis infection (p = 0.009). Trichinella seroprevalence was higher among rural residents and males. Subjects identified as Trichinella seropositive were not previously diagnosed and have not been treated for Trichinella infection with any specific therapy. Conclusions: The demonstration of T. spiralis antibodies in healthy blood donors suggests that Trichinella infection may be detected in asymptomatic individuals that were not previously diagnosed with this zoonosis.

Hepatitis E virus (HEV) is a major cause of acute hepatitis worldwide. In France, hyperendemic areas including Corsica have an anti-HEV Immunoglobulin G (IgG) prevalence higher than 50%. The aim of this study was to determine the seroprevalence of anti-HEV IgG in three adult populations in Corsica and the risk factors associated with antibody detection. Between 2017 and 2019, a total of 930 individuals, including 467 blood donors, 393 students or university staff members and 70 patients from general practice, were tested for the presence of anti-HEV IgG using the Wantai HEV IgG enzyme immunoassay kit and filled a questionnaire. The association between seropositivity and potential risk factors was tested with univariate and multivariate analyses. Out of the 930 samples, 52.3% (486/930) were seropositive—54.4% (254/467) among blood donors, 47.6% (187/393) among university students and 64.3% (45/70) among patients of general practice. Three main risk factors were identified: (i) skinning and butchering (Adjusted Odds Ratio aOR = 2.76, 95% confidence interval [95% CI] [1.51–5.37]; p-value < 10−3), (ii) consumption of a local pork live raw sausage (fittonu) (aOR = 1.95 95% CI [1.45–2.64]; p-value = 10−5), and (iii) increasing age (p-value = 0.003). Seropositivity rates between the different populations were homogeneous after age stratification. This cross-sectional study indicates a high anti-HEV IgG seroprevalence in the Corsican adult population, not significantly different between women and men and increasing with age. This serosurvey also showed homogeneity regarding the exposure to HEV among three different types of populations. Finally, we confirmed the endemicity of Corsica with respect to HEV and identified a strong association between consumption of figatellu/fittonu and the practice of skinning and butchering with the detection of anti-HEV IgG.
