BACKGROUND Population-based serologic studies are a vital tool for understanding the epidemiology of influenza and other respiratory viruses, including the early assessment of the transmissibility and severity of the 2009 influenza pandemic, and Middle East respiratory syndrome coronavirus. However, interpretation of the results of serologic studies has been hampered by the diversity of approac...

conclusions there was high percentage of seronegative (70.65 %) igg and igm antibodies in full-term pregnant women. they were susceptible to acute toxoplasmosis; thus, prenatal screening was recommend in our province after cost-beneficial analyses. results the participants’ age range was 15 to 45 years (average: 27.4 ± 13). of the 501 pregnant women, 70.65 % (n = 354) were seronegative for t. g...

BACKGROUND It has been suggested that the true case-fatality rate of human H5N1 influenza infection is appreciably less than the figure of approximately 60% that is based on official World Health Organization (WHO)-confirmed case reports because asymptomatic cases may have been missed. A number of seroepidemiologic studies have been conducted in an attempt to identify such missed cases. METHO...

OBJECTIVES We investigated the seroprevalence of the measles antibody and its attributable factors for the students who underwent routine 2-dose Schedule Era. METHODS The subjects were 996 students of the national measles seroepidemiologic study in December 2000 who had vaccination records. We conducted a questionnaire survey and we performed serologic testing for the measles-specific IgG by ...

background: health care workers (hcw) are at high risk of contracting various infectious diseases and play a dual role in the transmission of infections in health care facilities. objective: to determine the seroprotection against hepatitis b, measles, rubella, and varicella among hcws in a community hospital in qatar. methods: this is a cross-sectional survey conducted in a 75-bed community ho...

conclusions the seroprevalence of hev infection found in rural durango is higher than those reported in other mexican populations. consumption of untreated water is an important factor for hev exposure in rural areas in durango. the correlates of hev seropositivity found in the present study can be used for an optimal planning of preventive measures against hev infection. results one hundred (3...

conclusions chaharmahal and bakhtiari province could be categorized as a low endemic region for hepatitis b infection, with a seroprevalence similar to that in other provinces of western iran. vaccination seems to influence its decrease, especially in adolescents and youth. more surveillance and attention to risk factors are suggested to identify high-risk groups and to implement vaccination. r...

An NS1 serotype-specific indirect enzyme-linked immunosorbent assay (ELISA) was developed to differentiate primary and secondary dengue virus infections and serotypes of primary dengue virus infection. For this report, we carried out retrospective seroepidemiologic studies on serum samples collected from residents of Liuchiu Hsiang, Pingtung County, an isolated island in southern Taiwan during ...
