RSV retreated, flu fading, parainfluenza picking up: Queensland respiratory virus numbers up to Week 45, 2013

If you like to keep track of influenza cases in Queensland, Australia, then the Queensland Government's Queensland Health (QH) influenza data website is for you.

It's a great place to drop by and check out the comings and goings of influenza viruses and many of the other traditional respiratory viruses including adenoviruses (AdVs), parainfluenzaviruses (PIVs) 1, 2 and 3, human metapneumovirus (MPV) and respiratory syncytial virus (RSV) - the "Big8". Testing is not routinely conducted for the rhinoviruses (RVs).

The snippet below is from data that are publicly reported on the QH website. These images cover to the week beginning 3rd of November (up to Sunday, Nov 10th, 2013).

The charts highlight that
 the 2013 flu season is winding down in Australia, also reflected by the WHO global updates. This year flu followed on from what seemed to have been a large RSV season. Unfortunately I couldn't find data for this same time period last year to compare RSV prevalence.

In the wake of influenzavirus season, the parainfluenzaviruses are now on the rise in the lead up to summer. I expect the RVs (and enteroviruses) are also climbing, but in greater numbers.
