shit now I have to read up on the vaccine ahead of my next oncologist visit. Being immune suppressed sucks.

I suspect the area of concern mighbe a bit bigger than the suburb list suggested, given this find, but vaccination seems limited by degree of risk.

Lot of water still around low-lying parts of Taringa, Toowong and Indro so I suspect there'll be lot more mozzies around than usual. We're entirely screened at home, but a few of the little buggers get when we let the dogs in and out.

The virus needs to infect a host on which mosquitoes can get an nfected blood meal to bite a human. There aren't lots of wild pigs in suburban Brisbane (?) and unlikely to be lots of infected humans (?) so presumably wading birds in the area are providing the reservoir for the mosquitoes (?)

Does each mosquito need to get an infected blood meal, or once one mosquito carries the virus do all its offspring also carry the virus?

Transovarial transmission was detected by RT-PCR, but adults raised from those ova were not infected in this study, sgsin using RT-PCR to detect viral RNA

Thanks Ian. That’s somewhat reassuring… and I haven’t noticed any wild pigs here at Kangaroo Point

I think we're probably seeing birds transporting virus around then an as yet unidentified amplifying host(s) setting up new mosquito "hubs"

Hmmm. Well given the number of bush turkeys living in the river-side mangroves across the road from home, that's become less reassuring! And my (adult) son has woken up with a raging fever this morning. Sigh.

Or the flying fox theory may get tested.
Or perhaps rodents or another mammalian species like possums (needs work).

What about family pets?

mackayim.bsky.social•51 days ago

Cats & dogs can be infected without disease.
This is a bit chicken & egg'y.
Where would a pet get it from? A pig in an outer suburb (how close in do wild pigs regularly come to brisbane?). Or pet might be bitten by a mozzie that fed on an infected wading bird (🦢).

Perhaps 🦢>🦟>🚶‍➡️ simplest?
