The cases involve a 47-year-old man and his 6-year-old daughter. They arrived at Guangzhou Baiyun International Airport from Venezuela on March 3 and were afebrile at the airport. They subsequently traveled to Enping, Jiangmen, Guangdong and developed fever and rash on March 5. They are now hospitalized for isolation and management and are in a stable condition.

Zika virus infection is a mosquito-borne disease caused by Zika virus. The most common symptoms of Zika virus infection are fever and skin rash, usually accompanied by conjunctivitis, muscle or joint pain and general malaise.

The current major concern is the possible association with adverse pregnancy outcome (microcephaly) and neurological and autoimmune complications such as Guillain-Barré Syndrome.

Zika virus is mainly transmitted to humans through the bite of an infected Aedes mosquito. It can potentially be transmitted through blood transfusion. Zika virus has also been found in human semen and transmission by sexual contact has been confirmed.
