Can HIV be transmitted via mosquitos?

HIV can't be passed from one person to another through mosquitoes.

Imagine you're sharing a drink with your friend, that's like how HIV usually moves from one person to another, by touching or sharing something like blood. But now imagine a mosquito bites you, then goes and bites someone else. You might think it could pass on the HIV like a tiny messenger. But here’s the thing: when a mosquito bites you, it doesn’t just take your blood, it also spits out the old blood from its last meal before taking new blood.

So if a mosquito bites someone with HIV and then goes to bite another person, it's not giving them HIV, it's more like passing on a message that got mixed up along the way. The mosquito doesn't keep the HIV in its body long enough to pass it on again.

It’s kind of like sharing crayons, if your crayon is broken, and you give it to someone else, they might get a broken crayon too. But if you share with 10 people, only one might end up with the broken one, and the others will still have full crayons.
