Western Equine- less than 1,000 cases since 1964
Japanese- 67,900 cases typically occur annually

Globally mosquitoes transmit diseases to between 600,000,000- 700,000,000 people annually that we know about. Many diseases remain a mystery in their origins. Mosquitoes may be responsible for some of these diseases.
A little more than one hundred years ago malaria was thought to have originated from evil thoughts. Over 15,000 people died from malaria during the construction of the Panama Canal until the association was made between the disease and the mosquito.
The mosquito is presently the most dangerous living creature to the health of humankind. Every year over a million people are killed by mosquitoes. Untold numbers of dogs, cats, horses and birds are also killed by mosquitoes.
