Abstract
.Between 2010 and 2014, four chikungunya and two Zika virus infections were identified among 8,105 febrile children in southern Vietnam. Zika viruses were linked to French Polynesian strains, chikungunya to Cambodian strains. Against a backdrop of endemic dengue transmission, chikungunya and Zika present an additional arboviral disease burden in Vietnam.
Highlights
The emergence of the Zika virus (ZIKV) in the Western Pacific and Latin America, followed by the World Health Organization (WHO) declaration of a global public health emergency, has brought renewed attention to this and other epidemic arboviral infections

Sporadic cases of illness caused by the chikungunya virus (CHIKV) Indian Ocean Lineage (IOL) were first detected in Cambodia in 2011.5 In neighboring Vietnam, no virologically confirmed cases of CHIKV infection have been described
Summary
The emergence of the Zika virus (ZIKV) in the Western Pacific and Latin America, followed by the World Health Organization (WHO) declaration of a global public health emergency, has brought renewed attention to this and other epidemic arboviral infections. Between 2010 and 2014, four chikungunya and two Zika virus infections were identified among 8,105 febrile children in southern Vietnam. ZIKV has evolved into three distinct genotypes of similar geographic distribution: West African (Nigerian cluster), East African (MR766 prototype cluster), and Asian.[6] ZIKV was first detected in humans in 1954 but has recently emerged as a global threat to public health[7,8] because it can be an infectious teratogen to the unborn fetus and an occasional cause of Guillain–Barresyndrome in adults.[9,10] Since 2015, 67 countries have reported outbreaks (WHO situation report, October 27, 2016; http://www.who.int/ emergencies/zika-virus/situation-report/27-october-2016/).
