An analysis comparing the individual differences between over 40 strains of Zika virus (30 isolated from humans, 10 from mosquitoes, and 1 from monkeys) has identified significant changes in both amino acid and nucleotide sequences during the past half-century. The data, published April 15 in Cell Host & Microbe, support a strong divergence between the Asian and African lineages as well as human and mosquito isolates of the virus, and will likely be helpful as researchers flush out how a relatively unknown pathogen led to the current outbreak.
