[Comment] Zika virus and Guillain-Barré syndrome: another viral cause to add to the list
Zika virus was first identified in Africa in 1947, where it continues to cause regular outbreaks in sub-Saharan Africa but with very few clinical cases. In 1966, a distinct Asian lineage was found in Malaysia,1 but human disease remained uncommon in the Asia-Pacific region, despite serological surveys suggesting widespread occurrence of subclinical infections. The first recognised epidemic happened on the Micronesian island of Yap in 2007. It then spread across the Pacific to Easter Island and in 2015–16, it emerged in South and Central America and the Caribbean.
