Mainland: Avian influenza, human [Update]
Taiwan reported an imported measles case in a female flight attendant who resides in northern Taiwan. During the incubation period, she visited France, Singapore, China (Beijing and Hanzhou), and Thailand (Bangkok).
During the infectious period, she worked on Elite Class for Flight B62 that departed from Vienna, Austria to Bangkok during April 5 and 6, 2017, and then on Elite Class for Flight BR212 that departed from Thailand to Taoyuan, Taiwan on April 7.
Passengers who took Elite Class on the same flights on the same days are thus urged to conduct self-health management for 18 days (till April 24 for those who took the flight on April 5 and 6). If suspected symptoms develop, please put on a mask immediately, seek prompt medical attention and voluntarily notify the physician of the relevant exposure history.

A 6-month-old boy died of infant botulism in Japan last month after his family fed him honey.
(Source: ProMED-mail 11 April 2017)
[Editor’s notes: Infant botulism occurs mostly in infants under 6 months of age. It occurs when infants ingest Clostridium botulinum spores, which germinate into bacteria that colonize in the gut and release toxins. In most adults and children older than about six months, this would not happen because natural defences that develop over time prevent germination and growth of the bacterium. Clostridium botulinum in infants includes constipation, loss of appetite, weakness, an altered cry and a striking loss of head control. Although there are several possible sources of infection for infant botulism, spore-contaminated honey has been associated with a number of cases.]
