Japanese rival companies team up to fight dengue fever

Two rival companies in Japan have joined hands to develop a mosquito spray to fight the growing spread of dengue fever in Southeast Asia and elsewhere. The project combined Kao's technology and Earth's knowledge in the Southeast Asian market.

The companies said the spray uses a fine mist to saturate the wings and bodies of mosquitoes to prevent them from flying. The firms said they put aside their rivalry due to the growing health risks from the spread of dengue fever by mosquitoes.
