The Gyrovirus genus consists of the immunosuppressive Chicken Anemia Virus (CAV) prototype and since 2011 three other viral species found in sera/tissues of chickens, human feces, and on human skin. Here the genomes of two other gyrovirus species were characterized in diarrhea samples from Tunisian children whose main ORFs shared amino acid identity of 46-59% with those of the previously characterized gyroviruses and were provisionally named GyV5 and GyV6. All currently known gyroviruses grouped into two clades with distinct genomic features including replacement of the VP2 overlapping Apoptin gene with a distinct ORF of unknown function. Previous reports of gyrovirus DNA in human blood and on human skins warrant studies of possible human tropisms for these newly characterized gyroviruses.

The changing epidemiological profile of invasive infections (IIHi) is noted in the post-vaccination era. The aim of this study was to characterize phenotypically and genotypically invasive (Hi) isolates detected in Tunisian pediatric patients. A retrospective study was conducted in the microbiology laboratory of the Children's Hospital of Tunis over ten years (2013-2023).

Background: Understanding the connection between parental wellbeing and its impact on childhood depression is crucial in order to develop targeted interventions and support systems that can mitigate potential long-term effects on mental health. This study focuses on examining the properties of an Arabic translation of a questionnaire called Short Mood and Feelings Questionnaire Parent Version (SMFQ-P) as a preliminary step toward validating a culturally relevant screening tool for childhood depression in Lebanon.
Methods: A total of 502 parents, recruited through a snowball method, took part in the survey with an age of 36.

Little is known about differences in physical activity among children from urban and rural areas in low-to middle-income countries and some previous investigations revealed disparities in physical activity levels among children and adolescents residing in urban and rural environments. We aimed to: (i) assess the proportion of preschool-aged children (3.0-4.
