Emerging viral infections in South East Asia and the Pacific region

The epidemiology of several viral diseases underwent profound changes in South-East Asia and Oceania over the past decades. This was due to several factors. including the geographical distribution of vectors and the viruses they transmit: increasing traveling and trade: increasing ecological and demographic pressure. We reviewed the Current state of knowledge based oil published sources and available epidemiological data. The review was limited to potentially emerging viruses ill Southeast Asia and the Pacific reported in human cases. Dengue, Chikungunya, and Japanese Encephalitis viruses have recurred on a yearly, basis with a steady increase in these regions. Ross River and Barmah viruses now appear regularly in Australia. in all increasing number of cases. Nipah virus strikes regularly with limited but deadly epidemies in Southeast Asia. Finally, infections by lyssaviruses. Kunjin, Murray Valley, or Zika Viruses were also reviewed. (C) 2008 Elsevier Masson SAS. Tous droits reserves.
