A cluster of Zika virus infection in a Chinese tour group returning from Fiji and Samoa

ABSTRACT: Zika virus is currently causing extensive outbreaks in a number of countries in South and Central America and the Caribbean and has been associated with foetal abnormalities. We report an outbreak of Zika virus infection in a Chinese tour-group returning from a nine day holiday in Fiji and Samoa. The index case was a 38-year old male who developed symptoms while travelling back from Fiji to Hong Kong on the 14th February, 2016. A field investigation was initiated to define the epidemiological, clinical and virological characteristics of Zika virus infection in this tour group and revealed two further symptomatic infections and one asymptomatic infection among the 33 travellers; an overall infection attack rate of 12% in these travellers. Active surveillance led to detection of Zika virus RNA in the serum of one case four days prior to onset of symptoms and detection of Zika virus in saliva from one asymptomatic infection.
