Washington: New research into the fight against dengue may influence the development of anti-viral therapies that are effective against all four types of the virus.The findings, led by researchers at the University of Bristol, show for the first time that there may be significant differences in specific properties of the viral proteins for the four dengue virus types.Due to the effects of globalisation, including increased travel and urbanisation of human populations and the expanded geographical distribution of the mosquito vector that is responsible for the transmission of viral infections to millions of people, the number of individuals afflicted with dengue is rising.Infection with any one of the four types of dengue virus (DENV types 1 - 4) may result in a spectrum of illnesses ranging from dengue fever, a mild flu like illness which causes high fever and joint pains, to the potentially fatal dengue haemorrhagic fever.
