Fomites involved in influenza transmission are either hand- or droplet-contaminated. We evaluated the interactions of fomite characteristics and human behaviors affecting these routes using an Environmental Infection Transmission System (EITS) model by comparing the basic reproduction numbers (R(0)) for different fomite mediated transmission pathways. Fomites classified as large versus small su...

Background & aim: Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by human immunodeficiency virus (HIV). The awareness of HIV preventive measures and its transmission routes have an important role in controlling the HIV infection in the society. Regarding this, the present study aimed to investigate the awareness and attitudes of the high school students regarding HIV...

Sequencing pathogen samples during a communicable disease outbreak is becoming an increasingly common procedure in epidemiologic investigations. Identifying who infected whom sheds considerable light on transmission patterns, high-risk settings and subpopulations, and the effectiveness of infection control. Genomic data shed new light on transmission dynamics and can be used to identify cluster...

Transmission routes of PARV4, a newly discovered human parvovirus, were investigated by determining frequencies of persistent infections using autopsy samples from different risk groups. Predominantly parenteral routes of transmission were demonstrated by infection restricted to injection drug users and persons with hemophilia and absence of infection in homosexual men with AIDS and low-risk co...

We interviewed 1,716 women attending a family planning clinic in Nairobi between January 1990 and May 1991 about their knowledge of the acquired immunodeficiency syndrome (AIDS) and other sexually transmitted diseases (STDs). When participants in the study were asked to name spontaneously the STDs they knew, more than 90% of the women named gonorrhea and AIDS, and 75.0% named syphilis; 65.4% co...

HCV is transmitted principally through parenteral routes. The parenteral modes of transmission include blood transfusions, blood product infusions and organ transplantation. Vertical transmission of HCV has also been described. Though reports on the sexual transmission have been controversial, a fact that clearly emerges is that transmission of HCV through this route occurs at a very low effici...

context ebola hemorrhagic fever (ehf) is amongst severe and fatal viral hemorrhagic fevers. in february 2014, a strain of the ebola virus appeared in guinea and then in liberia, sierra leone, and mali. the aim of this study was to review the literature on ehf and discuss its routes of transmission and prevention. evidence acquisition we searched medical databases (pubmed, scopus) from july 1970...

conclusions health care providers need to pay special attention to sexual transmission of hcv among hiv-infected individuals, and should recommend control/preventive measures for hcv sexual transmission. results age of the index samples was 38.71 ± 7 years, and 33.2 ± 6.3 for their main heterosexual partners; the mean duration of sexual relationship for couples was 11.9 (median = 8.5) years. mu...
