Acute gastroenteritis (AGE) is one of the leading causes of death in children under the age of 5 years. In this pediatric age group, noroviruses are estimated to cause 200 million annual AGE cases worldwide [1]. With widespread vaccination against rotavirus, norovirus has become the predominant cause of childhood AGE in several Latin American countries such as Peru [2].

. Abstract. . Background. Noroviruses (NoVs) are the leading cause of diarrheal disease among all age groups worldwide, with an increased burden in developing countries. As there is no surveillance, epidemiological data is limited in Ethiopia. Hence, this study aimed to investigate the prevalence and associated factors of NoV infection among patients with diarrhea in the Amhara National Regional State, Ethiopia. .

Abstract . Background . Chronic norovirus infection (CNI) causes significant morbidity in immunocompromised patients. No effective prevention or treatment currently exists.Methods . Two patients with inborn errors of immunity, X- linked severe combined immunodeficiency (X-SCID) and DOCK8 deficiency, were followed longitudinally for clinical course, immune reconstitution, norovirus-specific T cell (NST) response, B cell reconstitution, and norovirus-specific antibody production.

. Abstract. Noroviruses are the second leading cause of death in children under the age of 5 years old. They are responsible for 200 million cases of diarrhoea and 50,000 deaths in children through the word, mainly in low-income countries. The objective of this review was to assess how the prevalence and genetic diversity of noroviruses have been affected by the introduction of rotavirus vaccines in Africa.

Background Norovirus (NoV) is the leading cause of diarrheal disease worldwide and the impact is high in developing countries, including Ethiopia. Moreover, there is a significant and fluctuating global genetic diversity that varies across diverse environments over time. Nevertheless, there is a scarcity of data on the genetic diversity of NoV in Ethiopia.

Norovirus (NoV) infections can lead to severe complications in immunocompromised patients (1). Nitazoxanide, ribavirin and intravenous (IV) or oral immunoglobulins (Ig) have shown limited efficacy (1,2). The gut microbiota has been described as impacting NoV infectivity and might constitute a therapeutic target (3), which can be modulated by faecal microbiota transplantation (FMT) (4).

Among intestinal and respiratory infections, norovirus acute gastroenteritis and varicella, respectively, were the most common causes. May and December presented the greatest number of causes of school outbreaks, whereas November to January presented the peak number of school outbreaks.

We report an increase in GII.17 norovirus outbreaks and sporadic infections of acute gastroenteritis in Austria, Germany, France, Ireland, the Netherlands, England and the United States during the 2023/24 season. A decrease in GII.4 coincided with GII.17 prevalence increasing to between 17% and 64% of all GII detections. Overall, 84% of the GII.17 strains clustered closely with strains first reported in Romania in 2021 and two new sub-lineages were identified.
