25. Increasing proportion of herpes simplex virus type 1 among women and men diagnosed with first-episode anogenital herpes: a retrospective observational study over 14 years in Melbourne, Australia.

Author

Abstract

Objectives: Reports of rising herpes simplex virus type 1 (HSV-1) genital infections relative to HSV-2 have been published up to 2006 in Australia. These changes have been attributed to declining childhood immunity to HSV-1. We described the temporal trends of HSV-1 and HSV-2 up to 2017 in Melbourne, Australia, to determine if the earlier trend is continuing.Methods: We conducted a retrospective review of the medical records of 4517 patients who were diagnosed with first episode of anogenital HSV infection at the Melbourne Sexual Health Centre, Australia, between January 2004 and December 2017. HSV-1 and HSV-2 were calculated as a proportion of all first episode of anogenital HSV infections. The change in the proportions of HSV-1 and HSV-2 over time was assessed by a χ2 trend test. Risk factors associated with HSV-1 were examined using a multivariable logistic regression model.Results: The proportion of first episode of anogenital herpes due to HSV-1 increased significantly over time in women (from 45% to 61%; ptrend<0.001) and heterosexual men (from 38% to 41%; ptrend=0.01) but not in men who have sex with men (MSM) (ptrend=0.21). After adjusting for condom use, partner number and age, the annual increase remained significant only in women (OR 1.08, 95% CI 1.03 to 1.13, p<0.001). In MSM, HSV-1 caused up to two-thirds of anogenital herpes in most years and HSV-1 was more likely to be diagnosed at an anal site than genital site (OR 1.69, 95% CI 1.23 to 2.32, p<0.001). Younger age (<28 years) was an independent risk factor for HSV-1 in all groups.Conclusions: The proportion of first-episode anogenital herpes due to HSV-1 has been rising in women since 2004. HSV-1 has become the leading cause of anogenital herpes in younger populations, women and MSM. [ABSTRACT FROM AUTHOR]

26. Influenza surveillance in Australia: we need to do more than count

Abstract

The authors suggest that negative results of laboratory tests for influenza should be made notifiable, together with laboratory-confirmed disease, and used to calculate the proportion of positive test results in real-time. They use data from the public health pathology services of three Australian states for the years 2004 to 2008 to demonstrate that incorporating laboratory-negative test data into national surveillance data would enhance understanding of influenza epidemiology.

Abstract

'Tubular aggregates' are morphologically distinct cytoplasmic structures that have been linked to a variety of pathological conditions. This report documents the presence of tubular aggregates in an insect cell line (C6/36 cells derived from Aedes albopictus) following inoculation of the cells with material derived from cell culture passaged homogenized Culex australicus mosquitoes. The tubular aggregates were detected in ~2% of treated cells and had three morphological forms that were termed primary, secondary and tertiary, with progressively greater levels of structural complexity. The findings indicate that tubular aggregates can be induced in an insect cell culture system by an unidentified agent present in some mosquitoes. [ABSTRACT FROM AUTHOR]
