Abstract
India is preparing to begin laboratory trials on a vector-control method to combat mosquito-borne viruses using a type of bacteria that infects insects. The work is part of a collaborative international effort to stem the spread of disease. An initial research phase will begin soon at Vector Control Research Centre in Puducherry, India, to study mosquitoes that are infected with Wolbachia bacteria. Though Wolbachia occurs in many insects, it is not usually found in the Aedes aegypti mosquito, a primary transmitter of the dengue and chikungunya viruses. Studies published last year show that Wolbachia can stop these viruses from growing inside the mosquitoes, and thus the bacteria might be used to control the spread of disease (PLOS Pathog., DOI: 10.1371/journal.ppat.1005434; PLOS Neglected Trop. Dis., DOI: 10.1371/journal.pntd.0004677). In 2016, nearly 100,000 people across India tested positive for dengue, and more than 200 died of the disease, data from the National Vector
