Organism
- Zika virus, also known as ZIKV, is an enveloped, icosahedral virus with a single-stranded, positive sense RNA genome. The most closely related virus is the Spondweni virus and is one of the two viruses in the Spondweni virus clade.[1]
- The ZIKV genome consists of 10,794 nucleotides that encode 3,419 amino acids[2]
- ZIKV is a member of the Flaviviridae family and of the flavivirus genus.
- There are two lineages for ZIKV: African and Asian.[2]
Human Pathogen
Transmission of ZIKV to humans is believed to occur through infected mosquitoes. The following species have been identified as vectors for the virus:[3]
The unnamed parameter 2= is no longer supported. Please see the documentation for {{columns-list}}.
2ZIKV has also been proven to be sexually transmitted between humans by Brian Foy, a biologist at Colorado State University, in 2009. [4] Mosquito-borne ZIKV is thought to initially replicate in dendritic cells near the site of inoculation before spreading to lymph nodes and then the bloodstream.
