RNA Viruses: A Review on Rapid Adaptation Potential and Globally Emerged Pandemics

Pathogenic RNA viruses continuously evading the human populations, and most prevailing in the last three decades.There are some notably examples as Human Immunodeficiency Virus, Ebola-virus and SARS-CoV2 globally emerged as threatened majorly to the public health concern from more than 180 known RNA virus species that may infect humans.New species and new variants of existing RNA viruses, being reported continuously, on average among these species, 89 percent considered the zoonotic origin.Therefore, we required more scientific understanding of the regular appearance or re-emergence of fatal pathogenic RNA viruses had been a profound impact on human health.The Current review provides the current status of RNA viruses, mainly emphasis on the host-virus relationship mapping, mechanism of adaptation in disease and strategies to control them and available vaccines against them.Conclusively, we required extensive research programs in the specialized antiviral drug programming interfaces would allow us to remain prepared until the next virus appears.
