Noroviruses constitute a significant aetiology of sporadic and epidemic gastroenteritis in human hosts worldwide, especially among young children, the elderly, and immunocompromised patients. The low infectious dose of the virus, protracted shedding in faeces, and the ability to persist in the environment promote viral transmission in different socioeconomic settings. Considering the substantial disease burden across healthcare and community settings and the difficulty in controlling the disease, we review aspects related to current knowledge about norovirus biology, mechanisms driving the evolutionary trends, epidemiology and molecular diversity, pathogenic mechanism, and immunity to viral infection.

Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), and Human Immunodeficiency Virus (HIV) remain a public health challenge globally. This study determined the prevalence and coinfection of HBV, HCV, and HIV among patients visiting Maria Goretti Hospital, Grimard Catholic Hospital, and Good News Hospital Anyigba, Kogi State. In a cross-sectional study, sera samples collected from 400 consenting patients were screened for HBV, HCV, and HIV using commercial immunodiagnostic test kits.

Article Synopsis
  • Gastroenteritis viruses, especially rotavirus, are the main cause of diarrhea in children under five in Africa, with a study analyzing 33 research papers from 2003 to 2023.
  • The study found rotavirus to have a prevalence of 31%, followed by norovirus and other viruses like adenovirus and sapovirus, with G1P[8] being the most common rotavirus genotype.
  • It emphasizes the need for improved vaccination strategies against rotavirus and ongoing surveillance to manage and control viral diarrhea cases in children effectively.

Background: High risk human papillomaviruses (HR-HPV) have a causal role in cervical oncogenesis, and HIV-mediated immune suppression allows HR-HPV to persist. We studied whether vaginal microbiome community state types (CSTs) are associated with high-grade precancer and/or invasive cervical cancer (HSIL/ICC).

Methods: This was a cross-sectional study of adult women with cervical cancer screening (CCS) at the Jos University Teaching Hospital (JUTH) in Jos, Nigeria, between January 2020 and February 2022.
