Hong Kong confirmed late Wednesday that a 31-year-old woman became the SAR's first imported Zika virus case this year, according to its Center for Health Protection.
The patient is in stable condition, and is receiving treatment in a private hospital. She has been suffering from a headache, a sore throat, nausea and vomiting since April 21 after she returned home following visits to Ecuador and Peru.
The World Health Organization has named the two South American countries as Zika virus affected.
Zika virus, transmitted by Aedes mosquitoes, can spread from a pregnant woman to her baby, which may result in microcephaly, severe brain malformation and other birth defects.
Hong Kong's health watchdog said it was satisfied that the risk of widespread local transmission was low, because the woman had mainly stayed at home before being admitted to hospital.
The authorities have again urged citizens to use anti-mosquito repellent while traveling in disease-affected countries. Pregnant women should avoid the area.
