The first case in Taiwan of severe fever with thrombocytopenia syndrome (SFTS), a tick-borne virus, was confirmed last week in a man in his 70s living in the north of the country, the Centers for Disease Control (CDC) said yesterday.
The man, who had not recently traveled overseas, but had often visited mountainous areas, sought treatment several times between Oct. 24 and Nov. 2 after experiencing reoccurring fever and vomiting, CDC disease prevention physician Chen Meng-yu (陳孟妤) said.
After having changes in consciousness and a rash, the man was hospitalized on Nov. 3, Chen said.

The hospital suspected dengue fever, but a blood sample sent to the CDC came back negative on Nov. 6, she added.
Disease prevention inspectors examined the case and on Wednesday last week confirmed that the man was infected with SFTS — the first case in Taiwan, Chen said.
The man remains in an intensive care unit, she said.
First confirmed in China in 2009, and subsequently in Japan and South Korea, SFTS is an emerging tick-borne infectious disease caused by a novel Phlebovirus, one of five, in the order Bunyavirales, CDC Deputy Director-General Philip Lo (羅一鈞) said.
Cases of SFTS increase from May to October and it has a mortality rate of 5 to 15 percent, Lo said, adding that the disease is transmitted by bites from Haemaphysalis longicornis, a tick more likely found in mountainous or hillside areas.
The incubation period is about seven to 14 days and patients might experience redness, swelling, a rash or a blister at the bite site, as well as fever, nausea, vomiting, loss of appetite, a low platelet count, a low white blood cell count or even multiple organ failure, Lo said.
As there is no antiviral drug for treating SFTS, supportive care is the treatment, he said.
People might worry that dogs or cats might bring a tick into the house, but there are many types of ticks and SFTS is mainly transmitted by H. longicornis, which has not yet been discovered in Taiwan, National Taiwan University College of Public Health associate professor Wang Hsi-chieh (王錫杰) said.
However, SFTS can also be transmitted by the Rhipicephalus microplus, so people who farm or frequently go mountain climbing have a greater risk of exposure, he said, adding that people should wear bright-colored, long-sleeve clothing, socks and insect repellent, but not stay in grasslands or forests for too long a time.
More than 5,300 cases of SFTS were reported in China from 2011 to 2016; 96 cases, including five deaths, have been confirmed this year in Japan — surpassing all the cases in Japan from 2013 to last year — and 223 cases have been confirmed this year in South Korea — surpassing the number there from 2014 to 2016, the centers said.
Since 2013, Taiwan has conducted tests for the SFTS Phlebovirus and its vectors, but all tests returned negative until last week’s case, Lo said.
A task force has been established to investigate the case’s source and SFTS is within a month to be announced as a notifiable communicable disease, he added.
Chinese spouse and influencer Guan Guan’s (關關) residency permit has been revoked for repeatedly posting pro-China videos that threaten national security, the National Immigration Agency confirmed today. Guan Guan has said many controversial statements in her videos posted to Douyin (抖音), including “the red flag will soon be painted all over Taiwan” and “Taiwan is an inseparable part of China,” and expressing hope for expedited reunification. The agency last year received multiple reports alleging that Guan Guan had advocated for armed reunification. After verifying the reports, the agency last month issued a notice requiring her to appear and explain her actions. Guan
GIVE AND TAKE: Blood demand continues to rise each year, while fewer young donors are available due to the nation’s falling birthrate, a doctor said Blood donors can redeem points earned from donations to obtain limited edition Formosan black bear travel mugs, the Kaohsiung Blood Center said yesterday, as it announced a goal of stocking 20,000 units of blood prior to the Lunar New Year. The last month of the lunar year is National Blood Donation Month, when local centers seek to stockpile blood for use during the Lunar New Year holiday. The blood demand in southern Taiwan — including Tainan and Kaohsiung, as well as Chiayi, Pingtung, Penghu and Taitung counties — is about 2,000 units per day, the center said. The donation campaign aims to boost
The Kaohsiung Tourism Bureau audited six hotels in an effort to prevent price gouging ahead of Korean band BTS’ concert tour in the city scheduled for Nov. 19, 21 and 22 this year. The bureau on Friday said that the audits — conducted in response to allegations of unfair pricing posted on social media — found no wrongdoing. These establishments included the local branches of Chateau de Chine, Hotel Nikko, My Humble House, and Grand Hai Lai, it said, adding that the Consumer Protection Commission would have penalized price gougers had the accusations been substantiated. The bureau said the Tourism Development Act
The military yesterday said it has located the flight data recorder, or black box, of an F-16V jet that disappeared off eastern Taiwan earlier this month, and it would soon deploy a salvage team to try to retrieve it. Air Force Command Headquarters said that while it had pinned down the location of the black box, it was still searching for the aircraft’s sole pilot, air force Captain Hsin Po-yi (辛柏毅). Without providing details, the air force said it had located the black box days after detecting some intermittent signals and would now engage a team of professionals to retrieve it. The air
