The flavivirus consists of three groups of viruses. Those groups include: pestivirus, hepacvirus and of course the flavivirus. These groups of the flavivirus are transmitted by mosquitoes, ticks or human blood. Actual virus types include: Dengue fever, Hepacvirus or Hepatitis C, Japanese Encephalitis, Spondweni Virus, St. Louis Encephalitis, West Nile Virus, Tick Borne Encephalitis, Yellow Fever and the Zika Virus. These viruses are considered single stranded-positive RNA(ribonucleic acid) viruses. This makes all of the flaviviruses treatable to some degree with medications that can be used or derived from current treatments for each of them.
Now for the comparison:
The Hepatitis C virus is a single stranded positive RNA virus as it is a considered a flavivirus. It is different from Hepatitis A virus,since the Hepatitis A virus has a symmetrical shape and comes from the picornavirus virus. Hepatitis B is a double stranded DNA virus that derives from the hepadna virus. And yes, there is a Hepatitis D, which is a single stranded circular RNA virus. In order for Hepatitis D to replicate it needs Hepatitis B, so as of this writing you need Hepatitis B to have Hepatitis D. Yes, this keeps going. Hepatitis E is a single stranded RNA virus that comes from the calicivirus. There are more hepatitis viruses on the radar, but hey we can always discuss those you know, whenever...
The Zika virus is also a single stranded positive RNA virus that is also known as a flavivirus, this would explain why the Hepatitis C virus and the Zika virus are in the same group of flavivirus viruses. Both the Hepatitis C virus and the Zika virus contain the NS5 protein. The NS5 protein is a non-structural protein that enables the RNA in each of the viruses to be replicated and spread. Antiviral medications that include, velpatasivir and ledipasvir can be used to inhibit the spread of the Zika virus by eliminating the viruses RNA replication.
Imagine a vaccine that can do this, if you are not using supplements as a preventative!
