On June 18, 2015, the Taiwan Centers for Disease Control (Taiwan CDC) declared two new Japanese encephalitis (JE) cases, and they are 42-year-old and 58-year-old males respectively. According to the epidemiological investigation, both the cases have not traveled overseas recently. However, there were pigeon and pig farms, and rice paddy fields within the 2 km radius of the cases’ residences. Thus, it is inferred that the source of infection is in the vicinity of the cases’ residences. At present, none of the cases’ household members have experienced any symptoms.
On June 4, the 42-year-old case sought medical attention, following the development of a sore throat and mild cough. He felt better the following day. However, he felt lethargic on June 6. He was transferred to the intensive care unit, in the morning of June 7, after he developed fever and unconsciousness.
Conversely, the 58-year-old case developed runny nose on June 6. He developed fever on the following day and sought medical attention on June 8. He was hospitalized in the intensive care unit on June 9, when his fever failed to subside and went into unconsciousness. Both cases are still hospitalized as to date.
In Taiwan, there have been three Japanese confirmed encephalitis cases, all occurring in southern Taiwan, this year according to Taiwan CDC’s surveillance data as of June 18.
