“…33 This finding may indicate the likelihood that the prevalence of HBV in the general healthy population is relatively high. Our findings were on the lower side when compared with studies from Sudan (11.7%), 25 and Tanzania (8.8%), 39 and slightly higher from Iran (0.13%), 37 Brazil (1.63%), 40 and Bangladesh (1.4%). 41 The overall prevalence of HIV in the present study was 0.23%.…”

Introduction Blood transfusion is linked to several risks, most notably the transmission of transfusion-transmitted infections (TTIs), including hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), syphilis, and malaria. The risk posed by these blood-borne infectious agents is high in developing countries, including Pakistan. This fact stresses the need for regular surveillance of TTIs. Therefore, the present study was undertaken to assess the seroprevalence of TTIs at a regional blood center. Material and Methods This was a retrospective 4-year descriptive study undertaken at the Regional Blood Centre in Peshawar, Khyber Pakhtunkhwa Province of Pakistan, on the blood donor data from June 2016 to May 2020. A total of 41,817 donors donated blood during the study period and were screened for HBV, HCV, HIV, syphilis, and malaria. To ensure donor privacy, donors were identified via codes and no personal information was available. The data were extracted from the ZAAVIA blood transfusion information system database. Results The study included a total of 41,817 donors—41,493 (99.22%) males and 324 (0.78%) females. Of them, 22,343 (53.43%) were voluntary donors while 19,474 (46.57%) were replacement donors. An overall TTI prevalence rate of 4.61% was found. The TTI prevalence rate in voluntary donors was 3.90% while 5.42% in replacement donors. The overall prevalence of HBV, HCV, HIV, syphilis, and malaria was 1.95, 1.38, 0.23, 0.91, and 0.14%, respectively. Conclusion The current study documented a high prevalence (1,929 out of 41,817, 4.61%) of TTIs, especially in replacement donors (1,057 out of 19,474, 5.42%), and low participation of female donors. The recommendations include the promotion of voluntary blood donors, enrolment of female blood donors, and screening of donated blood through highly sensitive screening assay (i.e., nucleic acid testing).

“…In contrast, the prevalence of anti-HCV rate decreased in voluntary donors in Cairo from 4.2 to 1.5% [ 18 ]. In comparison, prevalence rates for anti-HCV were 2.61% in Pakistan [ 26 ], 2.32% in Mali [ 27 ], 3.6% in Calabar, Nigeria [ 28 ], and 0.46% in Brazil [ 29 ].…”

Changing trends in seroprevalence rates of transfusion-transmitted diseases among blood donors in Jordan

Background Hepatitis B and C infections and transmission are a serious challenge to all healthcare systems. We studied seroprevalence rates of Transfusion Transmitted Diseases (TTD) among blood bank donors in Jordan from 2014 to 2019 as a follow-up study of our previously published work. In addition, we wanted to explore the efficacy of the mandatory vaccination of infants against hepatitis B virus (HBV) which was implemented by the Ministry of Health since 1995 for the eradication of HBV infection in Jordan. Methods We reviewed blood bank donors’ records at King Hussein Cancer Center (KHCC) from January 1st, 2014, until December 31st, 2019. Results of seropositivity prevalence rates for HBsAg, anti-HBcore, and anti-HCV, using Enzyme-Linked ImmunoSorbent Assay (ELISA) were compared to seropositivity rates from our previously published data. In addition, our results were compared to data obtained from other blood banks in Jordan, as well as compared to published information from blood banks in neighboring countries. Results The prevalence rates (%) of seropositive blood donors for viral hepatitis for the years 2014, 2015, 2016, 2017, 2018, and 2019, were as follows: HBsAg rates were 0.3386, 0.2108, 0.1801, 0.1898, 0.2068, and 0.2741; anti-HBcore rates were 4.1112, 3.2271, 2.9748, 2.8405, 2.6879 and 3.0986; and anti-HCV rates were 0.1129, 0.0486, 0.0548, 0.0654, 0.0782, and 0.0839, respectively. There was a significant increase in the prevalence of HBsAg, Anti-HBcore and Anti-HCV antibodies in 2019 (one sample z-score test, p < 0.00001). Conclusions Prevalence rates of hepatitis B and C infections among Jordanian blood bank donors showed a steady decline between 2009 and 2017, and these rates were much lower in Jordan than in neighboring countries. However, an increase in the prevalence rates of hepatitis B and C infections among blood bank donors was documented in 2019. While the reasons for this increase are not clear yet, these findings highlight the importance of renewed efforts to increase public health awareness of HBV and implement effective measures to prevent the transmission and infection with HBV, including national vaccination programs.

“…In urban Northern and Southern regions HTLV-1 prevailed over HTLV-2 [ 309 , 310 , 313 , 314 , 317 , 358 ]. The central region exhibited HTLV prevalence ranging from 0.02% to 1.6% [ 305 , 307 , 315 , 316 , 317 , 371 , 372 , 373 , 374 ], of which, for the Amazonian region, prevalence increased when indigenous villages were analyzed: 0.4–1.18% HTLV positivity in the city [ 375 , 376 , 377 , 378 ], whereas, in certain villages, the prevalence increased up to 13.88% [ 376 , 379 , 380 , 381 , 382 , 383 ]. In Argentina, most seroepidemiological studies were performed in the North and central regions, and an HTLV-1 endemic area was discovered in Jujuy, a North Western province.…”

The Epstein–Barr virus (EBV), Kaposi sarcoma herpesvirus (KSHV) and human T-lymphotropic virus (HTLV-1) are lymphomagenic viruses with region-specific induced morbidity. The RIAL-CYTED aims to increase the knowledge of lymphoma in Latin America (LA), and, as such, we systematically analyzed the literature to better understand our risk for virus-induced lymphoma. We observed that high endemicity regions for certain lymphomas, e.g., Mexico and Peru, have a high incidence of EBV-positive lymphomas of T/NK cell origin. Peru also carries the highest frequency of EBV-positive classical Hodgkin lymphoma (HL) and EBV-positive diffuse large B cell lymphoma, not otherwise specified (NOS), than any other LA country. Adult T cell lymphoma is endemic to the North of Brazil and Chile. While only few cases of KSHV-positive lymphomas were found, in spite of the close correlation of Kaposi sarcoma and the prevalence of pathogenic types of KSHV. Both EBV-associated HL and Burkitt lymphoma mainly affect young children, unlike in developed countries, in which adolescents and young adults are the most affected, correlating with an early EBV seroconversion for LA population despite of lack of infectious mononucleosis symptoms. High endemicity of KSHV and HTLV infection was observed among Amerindian populations, with differences between Amazonian and Andean populations.
