BACKGROUND The objectives of the study were to study the seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among health college students (HS) and health care workers (HCWs) in the Najran Region of south-western Saudi Arabia and to study the students' knowledge of occupational exposure to blood-borne viral infections. METHODS A cross-sectional study of a represen...

To describe seizures occurring in 3 healthy adults with influenza infection. Seizures associated to influenza infection are rare in adults without encephalitis. Clinical observations of 3 healthy adult patients with influenza A and B infection and seizures. We present here 3 healthy adult patients with seizures related to influenza A or B infection without evidence encephalitis, encephalopathy ...

We analyze how spatial heterogeneity in host density affects the advance of vector-borne disease. Infection requires vector infestation. The vector spreads only between hosts occupying the same neighborhood, and the number of hosts varies randomly among neighborhoods. Simulation of a spatially detailed model shows that increasing heterogeneity in host abundance reduces pathogen prevalence. Clum...

Molecular determinants and mechanisms of arthropod-borne flavivirus transmission to the vertebrate host are poorly understood. In this study, we show for the first time that a cell line from medically important arthropods, such as ticks, secretes extracellular vesicles (EVs) including exosomes that mediate transmission of flavivirus RNA and proteins to the human cells. Our study shows that tick...

BACKGROUND Tick-borne diseases are the most prevalent vector-borne diseases in Europe. Knowledge on the incidence and clinical presentation of other tick-borne diseases than Lyme borreliosis and tick-borne encephalitis is minimal, despite the high human exposure to these pathogens through tick bites. Using molecular detection techniques, the frequency of tick-borne infections after exposure thr...

PARV4 is a small DNA human virus that is strongly associated with hepatitis C virus (HCV) and HIV infections. The immunologic control of acute PARV4 infection has not been previously described. We define the acute onset of PARV4 infection and the characteristics of the acute-phase and memory immune responses to PARV4 in a group of HCV- and HIV-negative, active intravenous drug users. Ninety-eig...

background : drug injection is one of the most significant risk factors for viral hepatitis and human immunodeficiency virus (hiv) infection. the present study was performed to evaluate the frequency of hepatitis b (hbv) and hiv infection in idus and to identify the risk factors of these infections in this group in a central city of iran, shahre-kord. methods : this study was conducted in 2004 ...

background and aims. blood-borne infections such as hepatitis b, hepatitis c and hiv might be transmitted from one individual to another during dental procedures. therefore, sterilization and personal protection procedures are of utmost significance in dental offices. the importance of awareness of cross-infection and antiseptic principles lies in the fact that in most cases it is not possible ...
