Deadliest creatures globally by annual number of human deaths 2018

The deadliest creature in the world based on the number of human deaths per year is not a creature that humans usually find scary, such as a shark or snake. Mosquitos are by far the deadliest creature in the world when it comes to annual human deaths, causing around 750,000 deaths per year, compared to 100,000 deaths from snakes and only six from sharks.

Malaria

Mosquitos are the deadliest creature in the world because they transmit a number of deadly diseases, the worst of which is malaria. Malaria is a mosquito-borne disease caused by a parasite that results in fever, chills, headache, vomiting and, if left untreated, death. Malaria disproportionately affects poorer regions of the world such as Africa and South-East Asia. In 2017, there were around 435,000 deaths from malaria worldwide.

Mosquito-borne diseases in the U.S.

The most common mosquito-borne diseases reported in the United States as of 2016 included Zika virus, West Nile virus, malaria, and dengue viruses. Many of these cases, however, are from travelers who contracted the disease in another country - this is especially true for malaria, Zika, and dengue. From 2004 to 2016, the states of California, New York, and Texas reported the highest number of mosquito-borne disease cases in the United States.
