Mosquitos
The buzzing of mosquitoes is enough to annoy anyone, but apart from being an irritating insect, they are also very dangerous. Mosquitoes may be tiny, but they are also carriers of various diseases that kill millions of people all over the world every year. Dengue Fever is one of the fastest spreading diseases caused by mosquitos, with 2.5 billion people at risk for infection each year and over 100 countries affected worldwide. Apart from dengue, mosquitoes are also carriers of malaria, yellow fever, Zika virus, encephalitis, and Chikungunya.
