Emerging Viral Infectious Diseases-Peril to Human Health

In recent years there has been increasing attention towards the changing patterns of infectious diseases. In particular, the factors that lead to increases in the rates of these so-called ‘emerging infectious diseases' (EIDs) has focused primarily on the role of human activities, such as land use changes, population growth, increased contacts with wild animal reservoirs and the degradation of health care resources. Emerging Viral Diseases is the involved factors driving the appearance and spread of emerging viral diseases; the global health and economic impacts of recently emerging viral diseases in humans; preventive and curative measures for control of diseases. We focus on various viral infections as top listed by WHO which includes clinical manifestations, factors affecting, treatment and preventive measures that have received increased attention during the past five years. It need of hour to have better understanding of the basic requirements that lead to increased virus transmission between species and better viral replication in new species is needed to accurately assess the threat of a newly identified virus to the human population.
