Medical Case Reports

Of Late is the 'Covid-19' Among the Re-Emerged Viral Infections during Recent Years and what next?Possible Reasons and Precautions

Viral infections often created the significant threat of severe illnesses and death worldwide. This situation is more apparent in under developed and developing countries. There are four major genomes (double stranded DNA; single stranded DNA; double stranded RNA and single stranded RNA) that usually viruses possess. The virus diseases which ravaged the world during the late 20^th and early 21st centuries are RNA viruses. The viruses with RNA as their genome show uniqueness in multiplication and adaptation characteristics. The replicase of these viruses has the less proof-reading activity and prone for frequent mutations which help them to adapt positively. Dramatic climate change has witnessed for the past 30 years due to which the RNA viruses might force to attain genetic mutations for their survival and hence lead for the increased virulence. This situation may worsen in future and hence proper precautionary measures with at most care is required to handle the newly emerging pathogenic viruses
