Physical Activity among Adults Residing in 11 Countries during the COVID-19 Pandemic Lockdown.

During the novel coronavirus (COVID-19) pandemic, physical activity (PA) behaviors were altered worldwide due to public health measures such as "lockdown." This study described PA among adults residing in 11 countries during COVID-19 lockdown and examined factors associated with PA engagement. We conducted a cross-sectional anonymous survey among adults (≥18 years old) in 11 countries (Brazil, Bulgaria, China, India, Ireland, Malaysia, North Macedonia, Singapore, Spain, Turkey, United States).

Mental Health among Adults during the COVID-19 Pandemic Lockdown: A Cross-Sectional Multi-Country Comparison.

Despite the global impact of COVID-19, studies comparing the effects of COVID-19 on population mental health across countries are sparse. This study aimed to compare anxiety and depression symptoms during the COVID-19 lockdown among adults from 11 countries and to examine their associations with country-level COVID-19 factors and personal COVID-19 exposure. A cross-sectional survey was conducted among adults (≥18 years) in 11 countries (Brazil, Bulgaria, China, India, Ireland, North Macedonia, Malaysia, Singapore, Spain, Turkey, United States).

Diversity of human parechoviruses in Bulgaria, 2011: Detection of rare genotypes 8 and 10.

Human parechovirus (HPeV) infections are commonly asymptomatic but are also found in association with symptoms of the gastrointestinal and respiratory tract, or central nervous system. In order to study their distribution and genetic diversity in Bulgaria, specimens from 229 children aged <5years old hospitalized due to neurological manifestations (n=104) and acute gastroenteritis (n=125) were analyzed. Stool samples were tested using reverse transcription followed by real-time polymerase chain reaction toward the 5'UTR region, and the HPeVs detected were identified by PCR directed to VP1 followed by sequencing.

Animal picobirnavirus.

Picobirnavirus (PBV) is a small, non-enveloped, bisegmented double-stranded RNA (dsRNA) virus of vertebrate hosts. The name 'Picobirnavirus' derives from the prefix 'pico' (latin for 'small') in reference to the small virion size, plus the prefix 'bi' (latin for 'two') and the word 'RNA' to indicate the nature of the viral genome. The serendipitous discovery of PBV dates back to 1988 from Brazil, when human fecal samples collected during the acute gastroenteritis outbreaks were subjected for routine rotavirus surveillance by polyacrylamide gel electrophoresis (PAGE) and silver straining (S/S).

Aetiology of acute paediatric gastroenteritis in Bulgaria during summer months: prevalence of viral infections.

Paediatric acute gastroenteritis is a global public health problem. Comprehensive laboratory investigation for viral, bacterial and parasitic agents is helpful for improving management of acute gastroenteritis in health care settings and for monitoring and controlling the spread of these infections. Our study aimed to investigate the role of various pathogens in infantile diarrhoea in Bulgaria outside the classical winter epidemics of rotavirus and norovirus.
