Broadscale mosquito control may not be a practical option to reduce the risk of Japanese encephalitis virus but how the community accesses Japanese encephalitis vaccination will need to be reviewed for coming seasons. Surveillance of mosquitoes and arboviruses in urban areas must continue!

In 2024-2025, JEV has been active despite low mosquito and waterbirds. General consensus was that MVEV (and consequently Japanese encephalitis virus) didn't pose a risk to coastal regions (including metropolitan areas) due to lower mosquito and waterbird populations in local environment...

Its generally thought that Japanese encephalitis virus appeared and spread so widely in 2021-202 due to the flooding brought on by arrival of La Nina conditions across Murray Darling Basin; this brought a boom in waterbird and mosquito activity. This theory aligns with what we know of MVEV...

Okay SE QLD peeps, this is important. Japanese encephalitis can be fatal, and few of us will have any immunity to it. PLEASE take measures to avoid mozzie bites, and that includes cleaning up standing water after #Cyclone Alfred. Tip out pots, drain blocked gutters etc.

Cameron Webb @mozziebites.bsky.social · 16/03/2025
General consensus is that Culex annulirostris is the main vector but, to be honest, there is a lot to do to better understand the role of other mosquitoes. This is especially the case in coastal environments where more diverse vectors are found compared to inland regions

First wind, then rain. Next come the mozzies – here’s how to reduce your risk of bites and infections
Flood waters boost mosquito numbers. Disease outbreaks don’t always follow but it’s important to remove stagnant water from your property to reduce the disease risk.

I’m not sure that will have much impact, birds (as well as many other animals) eat mozzies but don’t make a significant impact on reducing mosquito numbers.
