| varicella infection--evidence for peak activity in summer months. | this study aimed to identify seasonal variations in the presentation of primary varicella infection in susceptible patients in victoria (a temperate region in south-east australia) by analysing victorian hospital admissions data and medical locum service data from the years preceding the introduction of a universally offered vaccination, complemented by available surveillance data from the neighbouring state, of south australia. contrary to the conventional assumption, which is based on observat ... | 2008 | 18359087 |
| a random cluster survey and a convenience sample give comparable estimates of immunity to vaccine preventable diseases in children of school age in victoria, australia. | we compared estimates of the age-specific population immunity to measles, mumps, rubella, hepatitis b and varicella zoster viruses in victorian school children obtained by a national sero-survey, using a convenience sample of residual sera from diagnostic laboratories throughout australia, with those from a three-stage random cluster survey. when grouped according to school age (primary or secondary school) there was no significant difference in the estimates of immunity to measles, mumps, hepat ... | 2002 | 12163264 |
| seroprevalence of varicella zoster virus, parvovirus b19 and toxoplasma gondii in a melbourne obstetric population: implications for management. | at an antenatal clinic at a melbourne obstetric hospital, 308 women were questioned about a known past history of infection with varicella zoster virus (vzv), human parvovirus b19 and toxoplasma gondii. immunoglobulin g (igg) concentrations were determined for the 3 infectious agents and a recalled history of infection was compared with the presence of specific antibody. exactly 66% of women recalled being infected with chickenpox (vzv) and 94% showed serological evidence of past exposure. altho ... | 2001 | 11284642 |
| the burden and cost of hospitalised varicella and zoster in australian children. | economic analyses of varicella-zoster virus (vzv) immunisation are sensitive to the costs of hospitalised cases, so there is a need to validate vzv hospitalisation data. | 2004 | 15542199 |
| prevalence of varicella-zoster virus genotypes in australia characterized by high-resolution melt analysis and orf22 gene analyses. | dna sequence variation analysis has divided varicella-zoster virus (vzv; human herpesvirus 3) into distinct geographical clades: european, asian, african and japanese. these genotypes are becoming increasingly prevalent within regions atypical to their original source and there has been the suggestion of recombination between genotypes. seventy-eight clinical isolates from hospitalized patients with varicella were collected in new south wales, the northern territory, western australia and victor ... | 2010 | 20466839 |
