RESUMEN
OBJECTIVES: Hepatitis C virus (HCV) remains a major public health burden for >30âyears since its discovery. It is estimated that >80 million people have been already infected. Direct-acting antiviral (DAA) treatment is now approved for young children over the age of 3âyears. Treating children before the development of high-risk behaviors is optimal. Thus, assessing the current epidemiology of HCV in children becomes important and may promote awareness. METHODS: Articles describing the prevalence of hepatitis C in children, were systematically reviewed. To assess HCV infection prevalence in the general population, studies discussing high-risk groups alone were excluded. RESULTS: Data from 58 studies were analyzed. National data was scarce. An overall prevalence of HCV in children of 0.87% was found, ranging from 0.34% in Europe to 3.02% in Africa. Prevalence of viremic infection is important and data synthesis from available data indicated that HCV viremia was detected in 56.8% of children. The prevalence of HCV according to sex was described in 25 studies but no difference between sexes was detected. HCV prevalence was significantly higher in children older than 10âyears (0.97%) when compared to those ages under 10âyears old (0.75%, Pâ<â0.001). CONCLUSIONS: Considering probable underdiagnosis of HCV infection in children, this information reveals that prevalence is substantial. One may argue that future strategies aiming towards HCV elimination, may need to include antiviral treatment of pre-adolescent children as well.

BACKGROUND: Although stroke is the fourth cause of death in Western societies, public stroke awareness remains suboptimal. The aim of this study was to estimate stroke risk perception and stroke awareness in Greece through a cross-sectional telephone survey. METHODS: A trained interview team conducted this cross-sectional telephone survey between February and April 2014 using an online structured questionnaire. Participants were selected using random digit dialing of landline and mobile telephone numbers with quota sampling weighted for geographical region based on the most recent General Population Census (2011). RESULTS: Between February and April 2014, 723 individuals (418 women [58%], 47.4 ± 17.8 years) agreed to respond. Among all respondents, 642 (88.8%) were able to provide at least 1 stroke risk factor; 673 respondents (93.08%) were able to provide correctly at least 1 stroke symptom or sign. When asked what would they do in case of acute onset of stroke symptoms, 497 (68.7%) responded that they would either call the ambulance or visit the closest emergency department. Only 35.3%, 18.9%, 17.2%, 20.7%, and 15.0% of respondents with atrial fibrillation, arterial hypertension, dyslipidemia, diabetes mellitus, and current smoking, respectively, considered themselves as being in high risk for stroke. CONCLUSIONS: Stroke risk perception in Greece is low despite moderate public stroke awareness.
