BACKGROUND The first wave of pandemic influenza A(H1N1)2009 (pH1N1) reached New South Wales (NSW), Australia in May 2009, and led to high rates of influenza-related hospital admission of infants and young to middle-aged adults, but no increase in influenza-related or all-cause mortality. METHODOLOGY/PRINCIPAL FINDINGS To assess the population rate of pH1N1 infection in NSW residents, pH1N1-sp...

Human T-cell lymphotropic viruses types 1 and 2 are probably among the most neglected blood-borne pathogens that have experienced significant changes in their epidemiology since discovery, which could be attributed to globalization and intravenous drug use practices as well as enhanced screening recommendations; however, systematic prevalence studies, especially in high-risk populations in Nort...

BACKGROUND The purpose of this study was to perform seroepidemiological investigation for determining the status of human fasciolosis in Pirabad Village, Lorestan Province, western Iran. METHODS Blood samples were taken from residents of the village including 801 individuals. Sera were separated and stored at -20°C until used. The samples were analyzed using ELISA. RESULTS Anti-Fasciola ant...

We investigated Estonian population and its selected subgroups for serological evidence of exposure to Ascaris lumbricoides, Echinococcus spp., Taenia solium, Toxocara canis, Toxoplasma gondii, and Trichinella spiralis. Serum samples from 999 adults representing general population, 248 children aged 14-18, 158 veterinarians, 375 animal caretakers, and 144 hunters were tested for specific immuno...

In the present study, we first report the seroprevalence of Dirofilaria immitis in dogs in Shenyang, northeastern China. Sera from 528 randomly selected dogs were examined for D. immitis antigen using SNAP®4Dx test kit; 12.7% tested showed seropositive. No significant difference of infection was observed in different genders and breeds (P>0.05), but the difference was significant in different a...

BACKGROUND Each year an estimated 390 million dengue infections occur worldwide. In Malaysia, dengue is a growing public health concern but estimate of its disease burden remains uncertain. We compared the urban-rural difference of dengue seroprevalence and determined age-specific dengue seroprevalence in Malaysia. METHODS We undertook analysis on 11,821 subjects from six seroprevalence surve...

AIMS AND OBJECTIVES To study the seroprevalence of anti HCV antibodies among Nepalese blood donors in relation to their age, sex, type of donation and times of donation. MATERIALS AND METHODS Descriptive cross-sectional study conducted in Nepal Red Cross Society (NRCS), Central Blood Transfusion Service (CBTS), Kathmandu, from December 1, 2006 to September 1, 2007. A total of 33,255 blood don...

OBJECTIVE To estimate seroprevalence of antibodies against the serogroup of epizootic hemorrhagic disease viruses (EHDVs) and describe spatial distribution of antibodies against EHDV among cattle herds in Illinois and western Indiana. SAMPLE POPULATION 9,414 serum samples collected from cattle in 60 herds over 3 transmission seasons. PROCEDURES Serum samples were tested for antibodies again...

Rose Bengal Plate test (RBPT) and Serum Agglutination test (SAT) were used to monitor the seroprevalence of brucellosis in horses in and around Faisalabad, Pakistan. Sera were screened by RBPT and positive or doubtful sera were further processed by SAT for confirmation. The overall seroprevalence of brucellosis in horses was 20.7 and 17.7% by RBPT and SAT, respectively. Source wise seroprevalen...

BACKGROUND Ecologic analyses of social and developmental correlates of country-level HIV seroprevalence may suggest strategies for combating the HIV/AIDS epidemic. METHODS Regression analyses were performed for 81 variables obtained primarily from United Nation agencies for 122 developing countries. Variable measures were compared between highest and lowest tertiles of HIV seroprevalence. R...
