The dengue virus causes epidemics in more than 100 tropical and sub-tropical countries, where over 2.5 billion people (over 40% of the world’s population) are currently at risk of dengue infections. In recent years, dengue has become the number one vector-borne disease in Sri Lanka. The worst ever dengue virus outbreaks experienced in 2009, 2010, and 2013 transformed dengue into a major health issue in Sri Lanka. There are no medicines or effective vaccines developed for dengue; therefore, mosquito vector control is the most promising option to control dengue virus transmission. The conventional vector control methods used currently have only limited success. In an attempt to find a solution to this problem, the research team lead by Professor Ranil Dassanayake, Department of Chemistry, University of Colombo in collaboration with Professor Nilmini Gunawardene, Molecular Medicine Unit, Faculty of Medicine, University of Kelaniya undertook to develop a dengue virus resistant transgenic Aedes aegypti mosquito (the primary vector of dengue virus transmission) line using an RNA interference (RNAi) based technology, as a component of the Ph.D. research project of Mr. Kalindu Ramyasoma.
