A Taiwanese woman in her 40s has been confirmed as the first person this year to have contracted chikungunya fever in China and tested positive in Taiwan, the Centers for Disease Control (CDC) said in a statement yesterday.
The woman visited friends in Guangdong Province’s Foshan and Shenzhen in the middle of last month and returned to Taiwan on Wednesday last week, the CDC said.
She developed a fever the next day and was admitted to hospital on Friday last week with rashes and pain in her limbs and ankles, the statement said.

Having heard chikungunya fever travel warnings on her flight back to Taiwan, the woman told medical workers about her travel history and that she had been bitten by mosquitoes during her trip, it said.
She was discharged after four days and is to be monitored until Aug. 26, it said.
Local health authorities have completed a vector mosquito density investigation, mosquito breeding source elimination and pest control activities around the woman’s home, the CDC said.
The CDC on Monday raised its travel advisory for Guangdong Province to Level 2 for chikungunya fever due to 2,892 new cases being reported in the region from July 27 to Saturday last week.
The CDC has a three-tier travel advisory, with Level 1 being “Watch,” advising people to “practice usual precautions,” Level 2 “Alert” calling for “enhanced precautions” and Level 3 “Warning” urging people to “avoid nonessential travel.”
As of Wednesday, there were 17 confirmed chikungunya fever cases in Taiwan this year, the highest figure for the period in six years.
All of the cases have been imported, with 13 from Indonesia, two from the Philippines and one each from Sri Lanka and China, the CDC said.
The fever is transmitted by Aedes albopictus (also known as the Asian tiger mosquito) and Aedes aegypti (also known as the Egyptian mosquito) carrying the virus, the agency said.
The public should take measures against mosquito bites when traveling to places where chikungunya fever is spreading, such as wearing light-colored clothing and using approved insect repellents, it said.
Symptoms of the disease are similar to dengue fever, including high fever, headache, joint pain in the lower back, ankles, knees, wrists or phalanges, joint swelling, rashes, muscle pain, nausea and fatigue, the centers said, adding that severe joint pain can last weeks, months or even years.
There is no specific antiviral treatment for chikungunya virus, only medications to alleviate the symptoms, it said, adding that it rarely causes severe illness or death, and most people fully recover.
As of Wednesday, China had reported more than 7,000 cases of the virus, mostly in Foshan.
The number of new cases appears to be dropping slowly, authorities said.
It appears to be the largest outbreak of chikungunya fever ever documented in China, said Cesar Lopez-Camacho, a researcher at the University of Oxford.
“What makes this event notable is that chikungunya has never been established in mainland China before,” Lopez-Camacho said in a statement. “This suggests that most of the population had no pre-existing immunity, making it easier for the virus to spread quickly.”

Authorities have detained three former Taiwan Semiconductor Manufacturing Co (TMSC, 台積電) employees on suspicion of compromising classified technology used in making 2-nanometer chips, the Taiwan High Prosecutors’ Office said yesterday. Prosecutors are holding a former TSMC engineer surnamed Chen (陳) and two recently sacked TSMC engineers, including one person surnamed Wu (吳) in detention with restricted communication, following an investigation launched on July 25, a statement said. The announcement came a day after Nikkei Asia reported on the technology theft in an exclusive story, saying TSMC had fired two workers for contravening data rules on advanced chipmaking technology. Two-nanometer wafers are the most
NEW GEAR: On top of the new Tien Kung IV air defense missiles, the military is expected to place orders for a new combat vehicle next year for delivery in 2028 Mass production of Tien Kung IV (Sky Bow IV) missiles is expected to start next year, with plans to order 122 pods, the Ministry of National Defense’s (MND) latest list of regulated military material showed. The document said that the armed forces would obtain 46 pods of the air defense missiles next year and 76 pods the year after that. The Tien Kung IV is designed to intercept cruise missiles and ballistic missiles to an altitude of 70km, compared with the 60km maximum altitude achieved by the Missile Segment Enhancement variant of PAC-3 systems.

A bipartisan group of US representatives have introduced a draft US-Taiwan Defense Innovation Partnership bill, aimed at accelerating defense technology collaboration between Taiwan and the US in response to ongoing aggression by the Chinese Communist Party (CCP). The bill was introduced by US representatives Zach Nunn and Jill Tokuda, with US House Select Committee on the Chinese Communist Party Chairman John Moolenaar and US Representative Ashley Hinson joining as original cosponsors, a news release issued by Tokuda’s office on Thursday said.

Tsunami waves were possible in three areas of Kamchatka in Russia’s Far East, the Russian Ministry for Emergency Services said yesterday after a magnitude 7.0 earthquake hit the nearby Kuril Islands. “The expected wave heights are low, but you must still move away from the shore,” the ministry said on the Telegram messaging app, after the latest seismic activity in the area. However, the Pacific Tsunami Warning System in Hawaii said there was no tsunami warning after the quake. The Russian tsunami alert was later canceled. Overnight, the Krasheninnikov volcano in Kamchatka erupted for the first time in 600 years, Russia’s RIA
