Emerging - re-emerging viruses: A global challenge illustrated by Chikungunya virus outbreaks.
Autor(es): Devaux Christian A
Resumo: In recent decades, the issue of emerging - re-emerging infectious diseases, especially those related to viruses, has become an increasingly important area of concern in public health. It is of significance to anticipate future epidemics by accumulating knowledge through appropriate research - by monitoring their emergence using indicators from different sources. The objective is to alert - respond effectively in order to reduce the adverse impact on the general populations. Most of the emerging pathogens in humans originate from known zoonosis. These pathogens have been engaged in long-st-ing - highly successful interactions with their hosts since their origins are exquisitely adapted to host parasitism. They developed strategies aimed at: (1) maximizing invasion rate; (2) selecting host traits that can reduce their impact on host life span - fertility; (3) ensuring timely replication - survival both within host - between hosts; - (4) facilitating reliable transmission to progeny. In this context, Arboviruses (or ARthropod-BOrne viruses), will represent with certainty a threat for the coming century. The unprecedented epidemic of Chikungunya virus which occurred between 2005 - 2006 in the French Reunion Isl- in the Indian Ocean, followed by several outbreaks in other parts of the world, such as India - Southern Europe, has attracted the attention of medical - state authorities about the risks linked to this re-emerging mosquito-borne virus. This is an excellent model to illustrate the issues we are facing today - to improve how to respond tomorrow.
