Diseases from mosquitoes are actually very serious and have killed many people. They can easily spread because mosquitoes are small and hard to catch with the naked eye. Though there are many other serious diseases harming (and killing) people every day, diseases like malaria, or the zika virus are very serious.

... have you ever heard of malaria, or yellow fever, or zika cuz those are all mosquito diseases. @sam123d
