综合媒体报导，12月19日，永州市宁远县1名女子确诊感染高致死H5N6禽流感，目前正在重症监护室接受治疗，截至21日仍需要使用呼吸器。

该县的跳礅石活禽交易市场从19日起开始休市，但20日，该县宣布所有活禽交易市场全部休市，包括8大农贸市场和乡镇44个农贸集市，并密切监测患者密切接触者。但当局并未说明染疫女子是否与关闭的市场有关。

据报导，“H5N6亚型禽流感”动物传人十分罕见，因此人体对该病毒的免疫力极低，甚至没有免疫力。如果“H5N6”禽流感病毒发生突变，出现人传人情况，对人类健康将是一段挑战。

As the outbreak heats up in China, a new deadly virus has broken out in Yongzhou City, Hunan Province. A woman infected with the highly lethal H5N6 bird flu has been admitted to the intensive care unit. The local live poultry trading market has been completely shut down.

Comprehensive media reports indicate that a woman in Ningyuan County, Yongzhou City, was diagnosed with highly lethal H5N6 avian influenza on Dec. 19 and is currently being treated in the intensive care unit, still requiring a respirator as of Dec. 21.

The county's Jumping Dunshi live poultry trading market has been closed since the 19th, but on the 20th, the county announced that all live poultry trading markets were closed, including eight major farmers' markets and 44 farmers' bazaars in townships, and that close contacts of the patient were being monitored closely. But authorities did not say whether the infected woman was related to the closed markets.

According to reports, "H5N6 subtype of avian influenza" animal-to-human transmission is very rare, so the human body's immunity to the virus is extremely low, or even no immunity. If the "H5N6" avian influenza virus mutates and a human-to-human transmission occurs, it will be a challenge to human health.
