The Langya henipavirus, which can be transmitted from animals to humans, has been discovered in China, with 35 human infections reported so far, Taiwan’s Centers for Disease Control (CDC) said, adding that the nation would establish a nucleic acid testing method to identify the virus.
A study titled “A Zoonotic Henipavirus in Febrile Patients in China” that was published in the New England Journal of Medicine on Thursday said that a new henipavirus associated with a fever-causing human illness was identified in China.
The study said an investigation identified 35 patients with acute infection of the Langya henipavirus in China’s Shandong and Henan provinces, and that 26 of them were infected with the Langya virus only, with no other pathogens.
The 26 patients developed symptoms including fever (100 percent), fatigue (54 percent), a cough (50 percent), loss of appetite (50 percent), muscle pain (46 percent), nausea (38 percent), headache (35 percent) and vomiting (35 percent).
They also showed a decrease in white blood cells (54 percent), low platelet count (35 percent), liver failure (35 percent) and kidney failure (8 percent).
When asked for confirmation, CDC Deputy Director-General Chuang Jen-hsiang (莊人祥) on Sunday that said according to the study, human-to-human transmission of the virus has not been reported, and that a serological survey of domestic animals found 2 percent of the tested goats and 5 percent of the tested dogs were positive.
Test results from 25 wild animal species suggest that the shrew might be a natural reservoir of the Langya henipavirus, as the virus was found in 27 percent of the shrew subjects, he said.
Chuang said the 35 patients in China did not have close contact with each other or a common exposure history, and contact tracing showed no viral transmission among close contacts and family, suggesting that human infections might be sporadic.
However, as the CDC has yet to determine whether the virus can be transmitted among humans, people need to pay close attention to further updates about the virus, he said.
As the Langya virus is a newly detected virus, Taiwan’s laboratories will need to establish a standardized nucleic acid testing method to identify the virus, so that human infections could be monitored, if needed, Chuang added.
NEW AGREEMENT: Malaysia approved imports last year after nearly two years of negotiations and inspections to meet quarantine requirements, officials said Up to 3.6 tonnes of pomeloes from Taiwan cleared Malaysian customs on Friday, in the first shipment of Taiwanese pomeloes to Malaysia. Taiwan-grown pomeloes are popular in domestic and overseas markets for their tender and juicy taste, the Ministry of Agriculture’s Animal and Plant Health Inspection Agency said. The fruit is already exported to Japan, Canada, Hong Kong, Singapore and the Philippines, it added. The agency began applying for access to the Malaysian market in 2023, compiling data on climate suitability, pests and diseases, and post-harvest handling, while also engaging in nearly two years of negotiations with Malaysian authorities and submitting supplementary
PEAK MONTHS: Data showed that on average 25 to 27 typhoons formed in the Pacific and South China seas annually, with about four forming per month in July and October One of three tropical depressions in the Pacific strengthened into a typhoon yesterday afternoon, while two others are expected to become typhoons by today, Central Weather Administration (CWA) forecaster Lee Ming-hsiang (李名翔) said yesterday. The outer circulation of Tropical Depression No. 20, now Typhoon Mitag, has brought light rain to Hualien, Taitung and areas in the south, Lee said, adding that as of 2pm yesterday, Mitag was moving west-northwest at 16kph, but is not expected to directly affect Taiwan. It was possible that Tropical Depression No. 21 would become a typhoon as soon as last night, he said. It was moving in a
One of two tropical depressions that formed offshore this morning could turn into a moderate typhoon by the weekend, the Central Weather Administration (CWA) said today. Tropical Depression No. 21 formed at 8am about 1,850km off the southeast coast, CWA forecaster Lee Meng-hsuan (李孟軒) said. It is expected to move in a northwesterly direction as it continues building momentum, possibly intensifying into Typhoon Mitag this weekend, she added. The radius of the storm is expected to reach almost 200km, she said. It is expected to approach southeast of Taiwan on Monday and pass through the Bashi Channel between Tuesday and Wednesday,
Tigerair Taiwan and China Airlines (CAL) today announced that several international flights were canceled or rescheduled due to Typhoon Ragasa. The Central Weather Administration (CWA) has maintained sea and land warnings for the typhoon. Its storm circle reached the Hengchun Peninsula (恆春半島) on Taiwan's southern tip at 11am today. Tigerair Taiwan said it canceled Monday's IT551/IT552 Taoyuan-Da Nang, IT606/IT607 Taoyuan-Busan and IT602 Taoyuan-Seoul Incheon flights. Tomorrow, cancelations include IT603 Seoul Incheon-Taoyuan, as well as flights between Taoyuan and Sapporo, Osaka, Tokyo Narita, Okinawa, Fukuoka, Saga, Tokyo Haneda, Nagoya, Asahikawa and Jeju. On Wednesday, the IT321/IT322 Kaohsiung-Macau round-trip would also be canceled. CAL announced that today's
