In Taiwan, the Central Epidemic Command Center for Zika Virus (CECC for Zika Virus) announced the seventh imported Zika case identified in Taiwan. The case is a 20-year-old female Singaporean who resides in Aljunied Crescent, Singapore.

During August 26 and September 3, she visited Japan with some friends. On September 1, she developed symptoms, including rash, joint pain, headache and conjunctivitis. Her symptoms persisted when she arrived in Taiwan on September 3. She sought medical attention on September 4 and 5. She was reported to the health authority as a suspected case by the hospital. Infection with Zika virus was laboratory confirmed in her after a second sample was collected. Based on the case’s incubation period and activity history, it was determined the case became infected with Zika virus in Singapore.

CECC for Zika Virus once again urges travelers visiting Zika-affected areas to take precautions against mosquito bites such as wearing light-colored clothing, long sleeves and long pants, applying officially approved mosquito repellent to exposed parts of the body, staying at accommodations installed with window screens, screen doors or air conditioners. Pregnant women are urged to postpone any unnecessary travels.

In Thailand, the health ministry announced Tuesday that the kingdom has recorded some 200 Zika cases since the beginning of the year. “Since January, we have recorded about 200 cases and over the past three weeks, we have confirmed an average of 20 new cases per week,” Ministry of Public Health spokesman Suwannachai Wattanayingcharoenchai told Reuters.
