Two zika and two chikungunya cases
On June 6, 2016, health authorities of the city of Kaohsiung announced that a Taiwanese couple who traveled to Fiji and the Solomon Islands from April 23 to May 16, 2016, returned to Taiwan with zika type symptoms. The woman was pregnant. Two rounds of screenings did not show any response for the zika virus but did show positive blood traces of the chikungunya virus.
On the evening of June 5, 2016, an Indonesian fisherman who entered Taiwan on June 1, 2016, was diagnosed positive for zika. This Indonesian fisherman is from Mojokerto in Indonesia.
On January 10, 2016, a man from Thailand entered Taiwan with a fever. Another 34-year-old man from Thailand was diagnosed on May 21, 2016, positive for zika. Both men came from the Udon Thani area of Thailand.
The chikungunya virus is transmitted by the Asian Tiger mosquito (Aedes albopictus) and the Yellow Fever mosquito (Aedes aegypti).
Dengue fever is also transmitted by the Aedes aegypti mosquito.
