Rotavirus group A (RVA) is a major cause of pediatric acute gastroenteritis (AGE). Vaccination is an effective public health strategy and Angola implemented it in 2014. This hospital-based study aimed to estimate the prevalence of RVA infection and the severity of AGE in children under five years of age treated at six hospitals in Luanda Province.

Porcine astrovirus (PoAstV), porcine sapovirus (PoSaV), porcine norovirus (PoNoV), and porcine rotavirus A (PoRVA) are newly discovered important porcine diarrhea viruses with a wide range of hosts and zoonotic potential, and their co-infections are often found in pig herds. In this study, the specific primers and probes were designed targeting the ORF1 gene of PoAstV, PoSaV, and PoNoV, and the VP6 gene of PoRVA. The recombinant standard plasmids were constructed, the reaction conditions (concentration of primers and probes, annealing temperature, and reaction cycle) were optimized, and the specificity, sensitivity, and reproducibility were analyzed to establish a quadruplex real-time quantitative RT-PCR (RT-qPCR) assay for the detection of these four diarrheal viruses.

Objectives: This study aimed to identify the aetiological spectrum, seasonal distribution and antimicrobial resistance patterns of diarrhoeal diseases in Bhutan.
Study Design And Setting: The study used a cross-sectional, retrospective analysis of secondary data gathered through a passive, hospital-based sentinel surveillance for diarrhoeal disease across 12 hospitals, representing Bhutan's demographically diverse regions.
Participants: A total of 3429 participants' data of all age groups who presented with diarrhoea at sentinel hospitals between 1 January 1 2016 and 31 December 2022 were analysed.
Rotavirus-Associated Myocarditis in an Immunocompetent Adult: A Case Report.

Internal Medicine, Weiss Memorial Hospital, Chicago, USA.
A previously healthy, 28-year-old man presented with a two-day history of diarrhea and chest pain, suggestive of infectious myocarditis. Initial workup revealed elevated troponin-I levels and diffuse ST-segment elevations on electrocardiogram (ECG). Transthoracic echocardiography showed a reduced left ventricular ejection fraction (40-45%), posteroinferior wall akinesis, and a small pericardial effusion.

Rotavirus C (RVC) causes acute gastroenteritis in neonatal piglets. Despite the clinical importance of RVC infection, the distribution and prevalence in pig populations in most African countries remains unknown. In this study, we identified RVC in Zambian pigs by metagenomic analysis.
