The World Health Organization (WHO) has set a target of eliminating viral hepatitis B and C by 2030. Vaccination against hepatitis B (HepB) remains the most effective strategy for controlling and eliminating Hepatitis B Virus (HBV) infection. The development of HepB vaccines started with plasma-derived vaccines, which have since been largely replaced by safer and more effective recombinant vaccines, now considered the gold standard for preventing HBV infections.

Introduction: Myeloproliferative neoplasms (MPN) are associated with clonal hematopoiesis, genomic instability, hemostasis dysregulation, and immune response. Classic BCR-ABL1 negative myeloproliferative neoplasms (BCR-ABL1 negative MPN), including polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF), are frequently associated with somatic abnormalities in JAK2, CALR, and MPL. Mutant clones induce an inflammatory immune response leading to immuno-thrombosis.

Gizzard erosion and ulceration syndrome (GEUS) is caused by a fowl adenovirus serotype 1 (FAdV-1) and was first reported in laying hens in Japan in 1993. This syndrome has emerged as an epizootic in Morocco since 2014, causing significant economic losses for the poultry industry, but no involvement of a FAdV has been confirmed. Thus, the objective of this work was to assess GEUS cases that occurred in the country and to determine the role of FAdVs in their occurrence.

In alignment with Morocco's national strategy for eliminating viral hepatitis, we aimed to characterize and update the virological profile of chronic hepatitis B patients. Demographic, serological and molecular parameters of 804 HBsAg-positive patients were retrospectively analyzed. Overall, 58.

Hepatitis B virus (HBV) infection is a global public health burden and affects approximatively 300 million people around the world. Since, HBV population is represented with genetic diversity, having different viral effects. Development of a new prognosis method play a key role on the efficiency of the different treatment.

Group A rotavirus (RVA) is the most important foodborne pathogen and is transmitted by oysters. The purpose of this study was to monitor and evaluate the prevalence of RVA in oysters collected in Oualidia Lagoon, Morocco from March 2018 to March 2019 and its relationship to watershed contribution. To achieve this, 312 oysters from 26 lots were collected and tested for viral contamination using real-time polymerase chain reaction.

Coronavirus disease (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is a betacoronavirus, and is associated with cytokine storm inflammation and lung injury, leading to respiratory distress. The transmission of the virus is mediated by human contact. To control and prevent the spread of this virus, the majority of people worldwide are facing quarantine; patients are being subjected to non-specific treatments under isolation.

Viral hepatitis B is a global public health problem affecting nearly two billion subjects; 3.3% of whom are from the WHO (World Health Organization) Eastern Mediterranean Region (EMRO). It induces both acute and chronic hepatic disorders with subsequent liver cirrhosis and hepatocellular carcinoma (HCC) in a considerable percentage of patients based on the age of exposure.

Background: Over 240 million people are chronically infected with hepatitis B virus (HBV), the leading cause of liver cancer worldwide. The quantification of the HBV DNA level is critical for monitoring the efficacy of antiviral treatment of chronic HBV patients.

Methods: In our study, we compared the performance of the HBV QS-RGQ assay to the CAP/CTM v2.

A one-step reverse transcription quantitative PCR (RT-qPCR) assay in combination with rapid RNA extraction was evaluated for routine testing of hepatitis C virus (HCV) RNA. Specific primers and probes were designed for the detection of a 150 bp sequence located in the 5'untranslated region (5'UTR) of HCV RNA. The target sequence was selected as the most conserved region between the six known HCV subtype sequences following an alignment.

Intravenous drug users (IDUs) represent a highly-infected reservoir for Hepatitis C virus (HCV) worldwide, harboring some of the most elevated prevalences and majority of the epidemic in developed nations. Studies aimed at sequencing regions of the viral genome uncovered amino acid mutations, some of which have been implicated in resistance to standard of care pegylated interferon/Ribavirin double therapy. Using the nested PCR method on the Core region of HCV strains in Moroccan IDUs living in the Tangier region this study sought to identify genotype-specific amino acid mutations, followed by Phylogenetic methods in order to compare them with international strains so as to identify sequences of highest homology.

The epidemiological transition has reduced infectious diseases mortality in most European countries, yet increased migrant influx risks importing diseases. All reported prevalence rates must be considered on a case-by-case basis depending on the disease in question, respective European Union (EU) country and migratory patterns at work. Tuberculosis has seen a re-emergence in Europe and is concentrated among migrants.
