Objective: Patients who frequently receive blood have high risk of hepatitis C virus (HCV) infection. This study aimed to evaluate the prevalence of HCV infection and potential risk factors among multiply transfused patients.Methods: A cross-sectional retrospective study was conducted in the hemophilia unit in Medical City in Baghdad, between June 1, 2016, and January 1, 2017. After taking consents and approval of ethical comity, the medical records of 1158 patients with hemophilia A and B, von Willebrand disease (vWD), thrombasthenia, Factors VII, X, and XIII deficiencies, and hypofibrinogenemia were analyzed for the presence of HCV antibody using (enzyme-linked immunosorbent assay). Cases of hemophilia were classified into mild, moderate, and severe.Results: The prevalence of HCV infection was 13.2%. Of total, 595 (51.4%) patients had hemophilia A and 99 (16.6%) were anti-HCV positive, while 225 (19.4%) had hemophilia B and 28 (12.4%) were antibody positive compared to 9 (7%) in vWD. Of those with hemophilia A, 515 (86.6%) had severe hemophilia, and 32 (32.32%) cases had acquired HCV infection after 1996 (after introduction of HCV screening in blood banks in Iraq). There was a statistically significant association with treatment by Factor VIII only.Conclusion: The prevalence of HCV in patients with inherited bleeding disorder is 13.2%. In this study, it was found that multitransfusion is the only predictor for HCV infection in this group of patients.

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.

Abstract Background Bluetongue (BT) is a vector-borne viral disease of ruminant and camelid species which is transmitted by Culicoides spp. The causative agent of BT is bluetongue virus (BTV) that belongs to genus Orbivirus of the family Reoviridae. The clinical disease is seen mainly in sheep but mostly sub-clinical infections of BT are seen in cattle, goats and camelids. The clinical reaction of camels to infection is usually not apparent. The disease is notifiable to the World Organization for Animal Health (OIE), causing great economic losses due to decreased trade and high mortality and morbidity rates associated with bluetongue outbreaks. The objective of this study was to investigate the seroprevalence of BTV in camels in Kassala State, Eastern Sudan and to identify the potential risk factors associated with the infection. A cross sectional study using a structured questionnaire survey was conducted during 2015–2016. A total of 210 serum samples were collected randomly from camels from 8 localities of Kassala State. The serum samples were screened for the presence of BTV specific immunoglobulin (IgG) antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). Results Seropositivity to BTV IgG was detected in 165 of 210 camels’ sera accounting for a prevalence of 78.6%. Potential risk factors to BTV infection were associated with sex (OR = 0.061, p-value = 0.001) and seasonal river as water source for drinking (OR = 32.257, p-value = 0.0108). Conclusions Sex and seasonal river as water source for drinking were considered as potential risk factors for seropositivity to BTV in camels. The high prevalence of BTV in camels in Kassala State, Eastern Sudan, necessitates further epidemiological studies of BTV infection in camels and other ruminant species to better be able to control BT disease in this region.

A cross-sectional study was conducted to determine the seroprevalence and associations with potential risk factors of brucellosis in indigenous cattle breeds at the livestock-wildlife interface area of Yankari Game Reserve, Bauchi State, Nigeria. A total of 1000 sera samples were examined from 44 herds using convenient and simple random sampling technique. Rose Bengal Plate Test (RBPT) and competitive Enzyme-linked Immunosorbent Assay (c-ELISA) were used as screening and confirmatory tests respectively. Of the 1000 samples, 23.5% samples were RBPT positive, and after the confirmatory test, the overall true animal-level prevalence was 4.1%. For the herd level prevalence, (47.7%) herds had at least one animal that is seropositive following both tests. Brucellosis seroprevalence was significantly associated with the following potential risk factors; herds that belong to a cooperative society member (p<0.042), herds that keep only cattle (p<0.001), herds that practice commercial farming system (p<0.011), herds that possess a herd size of 51 to 100 cattle (p?0.009) and herds that have no history of abortion and other reproductive disorder (p<0.009). No statistically significant differences in brucellosis seroprevalence was obtained within sex, breed and age groups It can be concluded that brucellosis is still endemic in the study area.

Objective: To know the status of hepatitis C virus (HCV) infection in children admitted in Pediatric ward of Bahawal Victoria Hospital Bahawalpur. Study design: Cross-sectional descriptive study. Place and duration of study: Pediatric unit-1 Bahawal Victoria Hospital Bahawalpur over a period of 2 months and 15 days. Material and methods: This study was conducted over 500 children admitted in children ward-1 of Bahawal Victoria Hospital Bahawalpur. Children of 1-15 years of age were included in the study. The blood samples of these children were taken at the time of admission and serum was tested for HCV with ICT method and later on confirmed by ELISA. Children having HCV infection were tested for SGPT level. Different risk factors for transmission of HCV infection were also studied. Results: Out of 500 children 43 were HCV positive by ICT method. Out of these 43 ICT positive children 38 were confirmed by ELISA. In this way 7.6% children were found positive for HCV. In 23 cases (60.5%) SGPT was raised (>40). Statistically significant risk factors for transmission of HCV infection found in this study were past history of blood transfusion and history of injections in past. Conclusions: HCV infection is quite common in children. Safe blood transfusions and use of disposable and sterilized syringes is important for prevention of this infection.

Aim. To determine the prevalence of anti-HCV and risk factors associated with HCV infection in Nigerians.Materials and Method. Patients attending a general outpatient clinic were administered a structured questionnaire on the risk factors for HCV infection. They were also tested for anti-HCV using a third generation enzyme-linked immunosorbent assay.Result. The seroprevalence of anti-HCV was 4.7%. Among the risk factors evaluated, none was found to be significantly associated with anti-HCV seropositivity.Conclusion. The risk factors associated with HCV infection in Nigerian patients are obscure. This warrants further studies on the epidemiology of this important cause of liver disease.

Objective. Knowledge regarding the prevalence and risk factors of hepatitis C virus (HCV) infection among pregnant women can give clue to health care providers regarding the appropriate management of HCV infection. Therefore, this study was conducted to determine the prevalence, genotypic pattern, and risk factors of HCV infection among pregnant women in the northern shores of the Persian Gulf, south of Iran. Methods. From January 2018 to June 2019, serum samples were obtained from 1425 pregnant women, ages ranging from 14 to 46 years ( 28.1 ± 5.99 ). Serum samples were tested for detection of anti-HCV antibodies using an enzyme-linked immunosorbent assay (ELISA) (HCV Ab ELISA kit, Dia.Pro, Milan, Italy). Following the extraction of nucleic acid, the molecular evaluation of HCV infection was performed by seminested reverse transcriptase-polymerase chain reaction assay (RT-PCR), targeting the 5 ′ untranslated region (5 ′ UTR) and core of HCV genome and sequencing. Results. Of the 1425 pregnant women, 19 women (1.33%, 95% CI: 0.85%–2.07%) were positive for anti-HCV antibodies. The majority of HCV-seropositive women were in the third trimester of pregnancy, educated, and had a history of blood transfusion, abortion, surgery, or dentistry. Moreover, Arab and Fars pregnant women and those aged >39 years had the highest rate of HCV seroprevalence. Nevertheless, none of these variables were significantly associated with HCV seropositivity. In contrast, HCV seropositivity was associated with place of residency, so that residents of Khormuj city had significantly higher HCV seroprevalence compared to the residents of other cities (OR: 7.05; 95% CI: 1.75–28.39; P = 0.006 ). According to the molecular evaluation, 9 of the 19 HCV-seropositive pregnant women (47.37%) had HCV viremia with genotype 3a. Conclusion. This study reports the HCV prevalence of 1.33% for anti-HCV antibodies and 0.63% for HCV RNA among pregnant women in the south of Iran. Considering the asymptomatic nature of chronic HCV infection and the fact that vertical transmission is possible in women with detectable viremia, therefore, screening of women before pregnancy is recommended to reduce the risk of HCV infection and its complications during pregnancy.

Background: Prevalence of Hepatitis C viral infection and its major risk factors has been found out in population of Batkhela, Khyber Pakhtunkhwa, Pakistan by taking number of volunteers from the interested area. HCV prevalence has not been researched in recent time here in this area, so that’s why we contributed. Materials and Methods: Ab rapid test cassette serum/plasma (USA) kit has been used for the mentioned purpose following by ELISA and finally PCR to find out active infection of virus. ICT positive individuals were reconfirmed by ELISA and then ELISA positive samples were carefully investigated by RT-PCR for Hepatitis C Virus. Results: The study population was of 770 volunteers belonging to the mentioned area of research, 453 males and 317 females. The overall prevalence was found to be 5.32% of HCV in Batkhela. This prevalence ratio was 3.12% in males and 2.20 % in females. 3rd generation ELISA was used to refine ICT positive samples which showed that 37 of the ICT positive samples had antibodies detected by ELISA. To find out active HCV infection, ELISA positive samples were refined by real time PCR which showed 2.98% of prevalence of active HCV infection in Batkhela based on HCV RNA in their blood. Principle Conclusion: Overall prevalence was found 5.32%, contaminated reused syringes and blades at Barbour’s shop, blood transfusion, surgical operations and unhygienic food in stalls etc were found significant risk factors for acquiring HCV infection. Body weakness and pale yellow skin color was common symptom in HCV positive volunteers. Safe sexual activities, blood screening before donation and sterilizing surgical equipment’s can protect us from Hepatitis C Virus.
