ABSTRACT

Coronaviruses is a group of highly diverse single stranded RNA virus. Corona included fever fatigue cough cold. Coronaviruses (CoV) are immeasurable family of viruses that cause sickness ranging from the common cold to more severe viruses such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). 2-14 days represents the current official estimated range for the novel coronavirus COVID-19. Coronaviruses are a group of enveloped viruses with nonsegmented, single-stranded, and positive-sense RNA genomes. Apart from infecting a variety of economically important vertebrates (such as pigs and chickens), six coronaviruses have been known to infect human hosts and cause respiratory diseases. At this times, several life-threatening viruses have emerged and coronavirus are one of these. Coronaviruses are characterized by crown-like spike that project from their surface, an unusually large RNA genome, replication strategy.
