Today's update from Singapore's MOH/NEA adds 26 new cases along with an interesting data point; genetic analysis indicates the virus spreading there was probably imported from Asia, not from the outbreak in the Americas.
While both stem from the Asian lineage of the virus, last July in Emerging Microbes & Infect: Growing Genetic Diversity Of Zika Viruses In Latin America, researchers reported:
. . . phylogenetic analysis revealed that the Asian lineage has evolved into two major lineages with high statistical support (Figures 1A and 1B), which we term the Oceanian and Latin American lineages.
Although the outbreak in the America's has been getting all of the attention, Zika has been spreading - often mistaken for Dengue or Chikungunya - in Southeast Asia and the Pacific Islands for years.
A*STAR’s Bioinformatics Institute will be releasing more information on this finding in the near future.
