All scientists are sure of is that the yaravirus is an amoebal virus.
Most known amoeba viruses have similar characteristics, so they can be classified into groups, but yara virus does not fit into any group.
It is a very unique virus, with only six out of 74 of its genes being similar to other known genes.
The yaravirus is small in size and genome, but it infects amoebas like giant viruses do.
