Mosquitoes do not reproduce as a result of infectious diseases. They reproduce at a greater rate because of global warming and they can spread diseases such as malaria.

I am assuming that you have unintentionally truncated your question.
Global warming prolongs mosquito breeding season, it also increases availability of collections of water where mosquitoes breed. In addition, in Africa some strains of mosquito lay eggs on grasses in depressions called demboes. The eggs remain dormant until rain fills up the dembo allowing the larvae to hatch and metamorphose into disease-carrying mosquitoes. Since several tropical diseases that are spread by mosquito are "transovarially" transmitted. That means, the virus in the mosquito infects the ovaries and it remains dormant in the mosquito egg. When it hatches the new mosquitoes spread the disease.
It is like a biological time bomb that has become more dangerous because of climate effects of global warming.
