On August 31, 2016, officials from the China Health and Family Planning Commission confirmed the first case of H9N2 influenza infection in Yunnan Province, China. Due to the potential risk of H9N2 transmission in Yunnan Province, the Taiwan Centers for Disease Control (Taiwan CDC) thus raised the travel notice level for the province to Level 2: Alert for avian influenza on the same day. Travelers planning to visit affected areas in China are urged to heighten their vigilance for avian influenza, practice good personal hygiene, avoid contact with poultry and birds and visiting live poultry markets, and consume only thoroughly cooked poultry and eggs in order to ward off infection.　　

The case is a 10-month-old baby boy who resides in Mengzi City. He was identified through the influenza-like illness surveillance. As of now, the case has recovered and been discharged from the hospital. None of the close contacts have developed suspected symptoms. Therefore, the case is determined to be a sporadic case. The currently available evidence suggests there has been no human transmission of the virus. Since fall 2015, a cumulative total of 8 H9N2 cases have been confirmed in China, including 3 in Hunan Province, 2 in Guangdong Province, and 1 each in Sichuan Province, Anhui Province, and Yunnan Province.

Currently, Taiwan CDC has issued a travel notice of Level 2: Alert for avian influenza to Zhejiang Province, Guangdong Province, Anhui Province, Hunan Province, Shanghai City, Jiangxi Province, Jiangsu Province, Sichuan Province, Fujian Province, Shandong Province, Hubei Province, Hebei Province, Beijing City, Tianjin City, Liaoning Province, Henan Province and Yunnan Province, and a travel notice of Level 1: Watch for avian influenza to the other provinces and cities in China, excluding Hong Kong and Macau.　　

Taiwan CDC advises travelers visiting China to practice good personal hygiene such as washing hands with soap and water frequently and putting on a mask when coughing and take preventive measures such as avoiding direct contact with poultry and birds or their droppings/dead bodies, and consuming only thoroughly cooked poultry and eggs to ward off avian influenza infection. If influenza-like illness symptoms develop upon arriving in Taiwan, please voluntarily notify the airline crew and the quarantine officer at the quarantine station in the airport. If the aforementioned symptoms such as fever and cough develop after returning to Taiwan, please put on a surgical mask and seek immediate medical attention. Moreover, please inform the physician of the recent travel and exposure history to facilitate diagnosis and treatment.
