I still don't understand why mosquitoes can't spread the disease. I would guss that it is because the mosquito is using the blood for food and adds digestive juices that kill the virus. But whatever the reason the researchers tested this theory and found it would not work. Many virus's cannot be transmitted by mosquito's, and a few bacteria as well. That said, it's always possible for a virus to mutate and became transmittable by mosquito’s, as well as other means, such as people coughing or sneezing small droplets of saliva which get into our open mouth or nostril. Or becoming transmittable by oral sex.

Virus would have to be able to make it's way from the mosquito's stomach back into his salivary glands. If it isn't capable of that then it can't be spread that way.... Something that was a famous discovery back when the US was building the Panama Canal and battling the Yellow Fever which had defeated the French. (Turned out that mosquitoes --- full of Yellow Fever infected blood right after a feeding paradoxically could not retransmit the infection. Only - if memory serves - exactly 12 days later could they reinfect people... the exact length of time it took for the pathogen transform itself inside the mosquito host, move through the mosquito's system, and then be secreted in the salivary glands.)
