Psychobehavioural responses to the 2014 Middle East respiratory syndrome-novel corona virus (MERS CoV) among adults in two shopping malls in Jeddah, western Saudi Arabia.

Sporadic cases of Middle East respiratory syndrome caused by a novel corona virus (MERS-CoV) were first detected in Saudi Arabia in June 2012. The number of cases was highest during April and May 2014. To assess determinants of psychobehavioural responses among the general population in Jeddah, western Saudi Arabia, a cross-sectional survey was conducted at the end of June 2014. Data included sociodemographic characteristics, level of anxiety, protective measures and social avoidance responses. A total of 358 participants completed the questionnaire; 58.4% were female, and the age range was 18-72 years. None of the participants was diagnosed with MERS-CoV. More than half (57.7%) recorded a moderate anxiety score using a visual analogue scale. Anxiety level was significantly associated with increased perception of susceptibility to infection and social avoidance behaviours related to travel and being in public places.

Sporadic cases of Middle East respiratory syndrome caused by a novel corona virus [MERS-CoV] were first detected in Saudi Arabia in June 2012. The number of cases was highest during April and May 2014. To assess determinants of psychobehavioural responses among the general population in Jeddah, western Saudi Arabia, a cross-sectional survey was conducted at the end of June 2014. Data included sociodemographic characteristics, level of anxiety, protective measures and social avoidance responses. A total of 358 participants completed the questionnaire; 58.4% were female, and the age range was 18-72 years. None of the participants was diagnosed with MERS-CoV. More than half [57.7%] recorded a moderate anxiety score using a visual analogue scale. Anxiety level was significantly associated with increased perception of susceptibility to infection and social avoidance behaviours related to travel and being in public places

Des cas sporadiques d'infection par le coronavirus du syndrome respiratoire du Moyen-Orient [MERS-CoV] ont été détectés pour la première fois en Arabie saoudite en juin 2012. Le nombre de cas le plus élevé a été observé en avril et mai 2014. Afin de mesurer les déterminants des réactions psycho-comportementales de la population générale de Djeddah, dans la partie occidentale de l'Arabie saoudite, une étude transversale a été conduite fin juin 2014. Les données incluaient les caractéristiques socio-démographiques, le niveau d'anxiété, les mesures de protection et la mise en place de mesures d'éviction sociale. Un total de 358 participants ont rempli le questionnaire, dont 58,4% de femmes, les âges étant compris entre 18 et 72 ans. Le MERS-CoV n'a été diagnostiqué chez aucun patient. Plus de la moitié [57,7%] a rapporté un score d'anxiété modéré en se basant sur une échelle visuelle analogue. Le niveau d'anxiété était associé de façon significative à une perception augmentée de sensibilité à l'infection et au phénomène d'éviction sociale lié à la possibilité de voyager ou de se rendre dans les lieux publics

Detection of non-primate hepaciviruses in UK dogs.

Non-primate hepacivirus (NPHV) has been identified in dogs, horses, bats and wild rodents. The presence of NPHV in dogs outside of the USA however is yet to be established. Here we describe for the first time the detection of NPHV in the UK dog population (described throughout the manuscript as CnNPHV). We examined tissues collected from dogs housed in a rehoming kennel where respiratory disease was endemic. CnNPHV RNA was detected in the tracheal tissues of 48/210 dogs by RT-PCR, and in the liver, lung and/or tracheal tissues of 12/20 dogs. The presence of CnNPHV RNA, and its tropism was confirmed by in situ hybridisation. Histopathological examination demonstrated a trend toward higher histopathological scores in CnNPHV RNA positive respiratory tissues, although, this was not statistically significant. Our findings broaden the geographic distribution and our understanding of CnNPHV. Further evidence of CnNPHV replication in canids warrants investigation.

A peptide mimotope of hepatitis C virus E2 protein is immunogenic in mice and block human anti-HCV sera.

Conformational B-cell epitopes on the HCV E2 protein recognized by human antibodies were characterized by the use of a peptide mimotope named K1. K1 was identified by two HCV anti-E2 monoclonal antibodies (mAbs) following selection and purification of phage clones containing a 15-mer random peptide insert. Murine antisera to the mimotope K1 recognized the E2 protein. Five of eight human sera from patients who had cleared HCV recognized the K1 mimotope. Binding to E2 in four individuals with the capacity to block E2-CD81 interaction was inhibited by the mimotope K1. The results demonstrate that anti-E2 antibodies in sera from patients who have cleared HCV infection are directed against a conformational B-cell epitope on E2 that can be mimicked with linear synthetic peptides. These findings could have implications for vaccine design by employing linear mimotopes to direct B-cell responses against those specific E2 epitopes that may correlate with immunity.
