The Alert Response Level under the Government's Preparedness and Response Plan for the Zika Virus Infection is activated
Zika virus infection is a mosquito-borne disease caused by Zika virus. The symptoms of Zika virus infection include skin rash, fever, conjunctivitis, muscle or joint pain and general malaise.
The current major concern is the association with adverse pregnancy outcome (microcephaly) and neurological and autoimmune complications such as Guillain-Barré syndrome (GBS). The World Health Organization has concluded that Zika virus infection during pregnancy is a cause of congenital brain abnormalities, including microcephaly, and that Zika virus is a trigger of GBS.
Apart from GBS, acute disseminated encephalomyelitis (a disease of the central nervous system) was recently found to be one of the neurologic manifestations possibly resulted from Zika virus.
Zika virus is mainly transmitted to humans through the bite of an infected Aedes mosquito. It has also been found in human semen and transmission by sexual contact has been confirmed. Sexual transmission of Zika virus between men who have sex with men has been identified. Other modes of transmission such as blood transfusion and perinatal transmission are possible.
