BACKGROUND To evaluate if, among children aged 3 to 15 years, influenza vaccination for multiple seasons affects the proportion sero-protected. METHODOLOGY/PRINCIPAL FINDINGS Participants were 131 healthy children aged 3-15 years. Participants were vaccinated with trivalent inactivated seasonal influenza vaccine (TIV) over the 2005-06, 2006-07 and 2007-8 seasons. Number of seasons vaccinated ...

West Nile virus (WNV) is a zoonotic, emerging mosquito-borne which can cause severe disease in the form of encephalitis and acute flaccid paralysis humans. In Assam, northeast India, arboviruses seem to be re-emerging, however, WNV has been little studied. The present investigation was carried out from April, 2018 March, 2019 study sero-positivity chicken urban peri-urban areas Guwahati, capita...

BACKGROUND Hepatitis E virus is an emerging infection in Africa with poor maternal and foetal outcomes. There is scanty data on the sero-prevalence of HEV infection among pregnant women in Ghana. This study highlighted the prevalence and risk factors associated with HEV infection among pregnant women in Cape Coast Metropolis, Central Region of Ghana. METHODS A multicenter (3 selected sites) a...

In a previous publication (de Blcourt, Polman, and de Blcourt-Meindersma, 1961), we drew attention to the familial occurrence of rheumatoid arthritis and ankylosing spondylitis, each of which shows a special hereditary factor, but we did not report on the presence or absence of the so-called rheumatic factor in probands and members of the family. The "epidemiology" of various rheumatic conditio...

Japanese encephalitis (JE) is one of the most important mosquito-borne viral diseases in Asia. Pigs are a natural host and the amplifier of JE virus. The sero-conversion rate to JE virus in sentinel pigs reflects the activity of JE virus in the region. We analyzed whether precipitation has any effect on the sero-conversion rate to JE virus in sentinel pigs. Linear regression analysis was perfor...

Lymphocyte phytohemagglutinin (PHA) responsiveness was found suppressed in both rubella sero-negative and sero-positive recipients of RA 27/3 strain of live attenuated rubella vaccine; the suppression was readily demonstrable only when a suboptimal dose of PHA was applied in the test. Lymphocytes from sero-negative vaccinees, which initially showed little or no in vitro response to concentrated...

BACKGROUND Antiretroviral therapy (ART) and condom use have been proven to reduce the risk of sexual transmission of human immunodeficiency virus (HIV) among HIV sero-different couples, but its full implementation remains a challenge. This study aims to assess HIV seroconversion rate of HIV-negative spouse and its associated risk factors among HIV sero-different couples in rural China. METHOD...

Background: Spectrum of COVID-19 disease ranges from asymptomatic or mild symptomatic to life threatening cases. Population based sero-epidemiological studies are useful for assessing the magnitude infection in a geographic area and it is helpful planning control measures. Objectives: To estimate sero-prevalence SARS CoV-2 antibody general population Tripura study factors associated with it. Me...

BACKGROUND Two-layer intestinal anastomosis increases the inflammatory response while single-layer anastomosis results in a better wound healing. However the four main kinds of stitches which may be chosen in performing single layer intestinal sutures never before had been comparatively studied. AIM To compare the four more commonly used types of single layer surgical anastomosis sutures of t...
