Evolution of dengue in Sri Lanka—changes in the virus, vector, and climate (original) (raw)

This paper examines the evolution of dengue viruses (DENV) in Sri Lanka, focusing on changes in the virus itself, the mosquito vectors that transmit it, and the climatic conditions affecting its spread. The study notes that urbanization and population growth have facilitated the epidemic of dengue in the region, where DENV has been endemic since the mid-1960s. It highlights the emergence of new DENV genotypes and clades, particularly the increasing incidence of dengue fever and dengue hemorrhagic fever associated with climatic variations and vector biology. The analysis emphasizes the importance of effective vector control programs and community cooperation in addressing morbidity and mortality associated with dengue.
