Why can certain blood transmittable things (West Nile, Malaria, Zika, etc.) be transmitted through mosquito bites, but other (AIDS, Hepatitis, etc.) cannot?

It's mostly a missconception that mosquitoes transmit diseases by allowing virus infected blood of one person to be innoculated into another. What happens ia that some virus actually infect mosquitoes (they actually multiply inside the mosquito gut and salivary glands), from which the virus is then innoculated in another person (usually, but not always) through the mosquitoes saliva. So why some virus can be transmitted by mosquitoes and others can't? Because some virus infect mosquitoes and thus survive and multiply inside the mosquito, those that dont infect the mosquito are just digested with the host's blood.
