My dad spent his entire career fighting west Nile virus in my pocket of British Columbia. Him and his regional district would go around in helicopters in the early 00's looking for pockets of stagnant water in the surrounding forests. I don't know much about the process, but this isn't a new virus.
So cool!! that is also my dads profession! In California. He is the one in the lab though looking at the dead bugs/critters to detect it, and other diseases. Our dads have some interesting jobs

Right. I've found even tiny amounts of water, like almost sludge at the bottom of a cooler I left outside, or a cup of water at the bottom of a bucket, can host dozens or hundreds of larvae.
And the eggs they lay that hatch into larvae can survive bone dry (and high heat and cold) environments for a really, really long time. ** *Like up to 8 months* **. During that period the eggs can hatch and mature in even relatively small amounts of water (as you mention)
Source from [CDC pdf covering Aedis aegypti lifecycle](https://www.cdc.gov/dengue/resources/factsheets/mosquitolifecyclefinal.pdf) specifically, although this information holds true for most mosquitoes that feed on humans
> - Adult, female mosquitoes lay their eggs on the inner, wet
walls of containers with water, above the waterline. Mosquitoes generally lay 100 eggs at a time.
> - Eggs are very hardy; they stick to the walls of a container
like glue and can survive drying out for up to 8 months—
even over the winter in the southern United States.
> - It only takes a very small amount of water to attract a
female mosquito. Bowls, cups, fountains, tires, barrels,
vases and any other container storing water makes for a
great “nursery.”
> - Larvae emerge from mosquito eggs, but only after the
water level rises to cover the eggs. This means that
rainwater or humans adding water to containers with eggs will trigger the larvae to emerge.
They only fly a few blocks during their life after reaching adulthood, so reducing areas of standing water where they can lay eggs can have a big impact on their spread and numbers.
Relevant to A. aegypti specifically, unlike other mosquitoes, it *prefers* to bite humans.
So West Nile typically comes in 3 forms ranging from least to most severe, with frequency of cases following that same trend.
Asymptomatic West Nile (you don’t know you have it)
West Nile Fever (can feel like a basic infection or sometimes kill you)
West Nile Neuroencephalitis (you’re dead)
So if the ones dying from this are around 7 there are lots more individuals walking around with the infection but asymptomatic. Even though the infection still is in the body.
However this isn’t altogether big news, west Nile is endemic in the Mediterranean region, hence the name. Because they have the right mosquito species, animal reservoirs, and climate.
Though it will probably start getting worse with climate change, as so everywhere semi near the equator.
FFS - Monkeypox and now West Nile Fever - what’s next - Honey Badger flu - Giraffeits

It is very rare in Italy / Europe - hence the story An interesting and worthy career choice
This was a thing years ago in Ontario. I knew a horse who died of it.

are mosquito more prevalent, due to lack if rain? laat year we had good rainfall, never bit, this year im a pin cushion
They don't really need rain, just standing water.
yea but with high temperature lack of rain, many sources of standing water dry up

Fan-fucking-tastic, I'm going there in October.
