I've had dengue fever. There are a few different strains and I had one of the milder ones but it was still enough to put me in the hospital for dehydration as an otherwise healthy 20yo.

In Thai it's known as hemorrhagic fever, but unlike in English, where "hemorrhagic" is a technical term where the meaning isn't clear or is softened, in Thai it's just three simple Thai words: ไข้เลือดออก, "fever [that makes] blood [come] out". Luckily I didn't have any hemorrhaging.

Earlier quoted context omitted.

Direct kills are probably pretty marginal, but Singapore employs insecticides in prodigious quantities. It's almost eerie how eg hawker centres have no flies and outdoor gardens are almost entirely devoid of insects (whereas if you cross the border to Malaysia, both can be found in abundance).

Huh. Does Singapore not need insect pollinators?

I believe there's very little agriculture in Singapore - almost all food is imported.

Well, you still had to add extra words to make the meaning clear enough.

Truly a fascinating method. Apparently, the most effective mosquito population control technique. The counter-point argument offered at the end of the article/video is totally lame. I find it slightly annoying when journos feel compelled to seek contrarian positions just for the sake of form, regardless of the quality of the arguments.

It's an extra-lame counterpoint because male mosquitos don't bite, and they're only releasing males.

How do they separate the genders?

For small scale production it's a manual process (size differences), for industrial scale it's using ML and blowing air in a certain direction. Basically the mosquitoes are brought under a camera in some form of tube, and depending on the gender they are blown into a certain direction separating male and female.

I don't think this is part of Verily, and afaik Verily was one of the first that starting doing this.

Singapore has some limited 'agriculture' (and a big shift to industrialised hydroponics and stuff); but most is outside the city.

It's indeed quite scary how much pesticides are currently used and how a lot of the green patches and parks have little flies, butterflies, and other insects.

It's lame but it's true that during the Verily release of mosquitoes from their carts [1] in HDB estates, they had a lot of people complain how since releasing they saw more mosquitoes and were bitten more often, while the mosquito traps showed a clear decline in population.

As far as I was told, it is not the strains are mild or not, there are in total 4 strains, you get immune with each one you get, but each it will be worse.
