Introduction / objectives The habit of removing the nails cuticles of hands and feet is a typical cultural practice in Brazil and can be an important factor for hepatitis B and C infection. We conducted a seroepidemiological survey of hepatitis B and C in professional manicures/pedicures in salons in Sao Paulo Brazil, with the aim of estimating the prevalence of serological markers of HBV and H...

Because background seroepidemiological data are required before nationwide vaccination against hepatitis B virus (HBV) is attempted, the rate of exposure to HBV was investigated in two high-risk Saudi groups: patients on haemodialysis and patients with congenital bleeding disorders. Although the HBsAg carrier rate was higher in patients with congenital bleeding disorders (11.1%) than in patient...

A seroepidemiological survey was carried out during 1994 in the municipality of Paracambi, state of Rio de Janeiro. Haemagglutination inhibition test positivity was detected in 145 out of 370 (39.2%) schoolchildren. The frequency of positive test by sex was 53.8% (78/145) female and 46.2% (67/145) male. Distribution by age showed the increasing of antibody positivity in older children. Strains ...

INTRODUCTION: Emerging diseases are of great interest, especially those associated with high mortality rates such as hantaviruses. We aimed to conduct a seroepidemiological survey to determine the levels of hantavirus infection. METHODS: In-house enzyme-linked immunosorbent assay (ELISA) was used to detect specific antibodies. RESULTS: Of the 429 samples collected, seropositivity of 3.9% to...

Background: Serological studies of antibody prevalence in response to infection with the acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are useful monitor epidemic progression disease and evaluate rates. In this study, we estimated anti-SARS-CoV-2 antibodies (IgM IgG) a Portuguese sub-district, during National lockdown - January-March 2021.Methods: seroepidemiological survey participants...

Last year the COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has started. The new coronavirus is highly contagious and causes complications. mechanisms of humoral immunity kinetics SARS-CoV-2 specific antibodies in a population are not well understood. Therefore, we aimed to summarize analyze numerous global Russian serological studies for understanding...

CONSISE - The consortium for the Standardization of Influenza Seroepidemiology - is a global partnership to develop influenza investigation protocols and standardize seroepidemiology to inform health policy. This international partnership was formed in 2011 and was created out of a need, identified during the 2009 H1N1 pandemic, for timely seroepidemiological data to better estimate pandemic vi...

A foamy virus isolated by Achong et al. from a human nasopharyngeal carcinoma was studied to determine its antigenic relationship to the eight known simiam foamy viruses (SFV). Using reciprocal cross-immunofluorescent and cross-neutralization techniques, we found the human isolate to be closely related to SFV type 6. In a seroepidemiological survey, neutralizing antibody to the human foamy viru...
