自去年底武汉爆发冠状病毒以来,全球官方死亡人数已超过1016人,全球各国政府都在努力遏制这种快速传播的疾病。
这中国国家卫生委员会周一,他们宣布在大陆已经收到42638例确诊病例和1016例死亡病例的报告。总共有3,996名患者已经治愈并从医疗保健中出院,剩下37,626例确诊病例和另外21,675例疑似病例。其中,7,333人被确认感染了该病毒,情况严重。
中国在过去一天宣布了108例死亡,其中103例在新病毒的震中湖北省,1例在北京,1例在天津,1例在黑龙江省。
官员们还证实,香港有42例确诊感染,澳门有10例,台湾有18例。香港已确认一例死亡,菲律宾已确认一例死亡。截至发布时,美国已确诊12例病例,并且一次死亡一名美国公民,因病毒于周末在武汉去世。
自去年12月首次出现在中国中部湖北省武汉市的海鲜批发市场以来,这种新病毒已经通过空中和海上传播到美国和十几个其他国家的公民。尽管死亡率(大约2.1%)比非典病毒(大约9.6%)低得多,但冠状病毒现在已经比非典病毒杀死了更多的人,非典病毒的总死亡人数为774人。
2020年2月10日,在泰国曼谷的素万那普国际机场,随着冠状病毒的传播,旅客们戴着口罩排队等候入境。据卫生官员称,冠状病毒已经影响了亚洲超过40,500人,中国大陆已有大约910人死亡。
中国卫生官员对病毒传播是否是空气传播感到矛盾,一位专家声称“理论上”可能是空气传播。在星期六新闻发布会上海市民政局副局长曾群说,冠状病毒通过直接传播传播,包括身体接触。
然而,中国日报中国共产党宣传部所属的英文报纸《中国日报》报道称,曾轶可说,这种病毒也能通过气溶胶传播。“根据医学专家的说法,气溶胶传播是指病毒与空气中的飞沫混合形成气溶胶,吸入后会导致感染,”曾说。
中国疾病预防控制中心研究员冯周日对这一观点提出质疑,他在新闻发布会上表示,没有证据表明冠状病毒可以形成气溶胶。冯坚持认为,最可行的传播途径仍然是直接的,包括一个未受感染的人在空气中呼吸一个受感染的人的咳嗽或打喷嚏。
根据世界卫生组织应急委员会的建议,该组织总干事在一月份宣布冠状病毒为国际关注的公共卫生紧急事件。最近几周,特朗普政府表示,已经从武汉疏散了800多名美国人,以保护他们并遏制病毒。
其他国家也采取了类似的预防措施来保护本国公民,其中包括美国、菲律宾、日本和澳大利亚,这些国家通过了临时旅行限制来控制疫情。

OFFICIAL CORONAVIRUS DEATH TOLL SURPASSES 1,000, MORE THAN 42,500 INFECTED
The official worldwide coronavirus death toll has surpassed 1,016 since the outbreak began in Wuhan late last year, as governments around the globe work to contain the fast-spreading disease.
The Chinese National Health Commission on Monday announced that they had received 42,638 reports of confirmed cases and 1,016 deaths in the mainland. In total, 3,996 patients have been cured and discharged from medical care, which leaves 37,626 confirmed cases and an additional 21,675 suspected cases. Of those, 7,333 who are confirmed to have contracted the virus are in serious condition.
China announced 108 deaths in the past day, with 103 in the Hubei province, the new virus' epicenter, one in Beijing, one in Tianjin and one in the Heilongjiang province.
Officials also confirmed 42 confirmed infections in Hong Kong, 10 in Macao and 18 in Taiwan. One death has been confirmed in Hong Kong and one in the Philippines. There are 12 cases confirmed in the U.S. as of publication, and one death of an American citizen, who passed away due to the virus in Wuhan over the weekend.
Since first appearing at a wholesale seafood market in the Chinese city of Wuhan, located in the central Hubei province, in December, the new virus has spread through air and sea travel to citizens in America and over a dozen other foreign countries. Although the fatality rate (roughly 2.1 percent) is much lower than the SARS virus (roughly 9.6 percent), coronavirus has now killed more people than SARS, which had a total death toll of 774.
As Coronavirus spreads travelers arriving wait in line at immigration wear masks at Suvarnabhumi International airport in Bangkok, Thailand on February10, 2020. The Coronavirus has effected more than 40,500 people in Asia, according to health officials with approximately 910 people who have died in mainland China.
Chinese health officials are conflicted as to whether the virus spread is airborne, with one expert claiming that "in theory" it could be. During a Saturday press briefing, Zeng Qun, the deputy head of the Shanghai Civil Affairs Bureau, said coronavirus spreads through direct transmission, which involves physical contact.
However, China Daily, an English-language newspaper owned by the Publicity Department of the Communist Party of China, reported that Zeng said the virus is also capable of aerosol transmission. "Aerosol transmission refers to the mixing of the virus with droplets in the air to form aerosols, which causes infection after inhalation, according to medical experts," Zeng was quoted as saying.
Feng Luzhao, a researcher from the Chinese Center for Disease Control and Prevention, challenged the view on Sunday, telling a press conference there is no evidence to suggest coronavirus can form aerosols. Feng maintains that the most feasible route of transmission is still direct, which includes an uninfected person breathing in the air of an infected person's cough or sneeze.
The World Health Organization's director-general in January declared coronavirus a public health emergency of international concern, following a recommendation from the body's emergency committee. In recent weeks, the Trump administration said it has evacuated over 800 Americans from Wuhan to protect them and contain the virus.
Other countries have similarly taken precautions to safeguard their citizens, with the U.S., Philippines, Japan and Australia among those who have passed temporary travel restrictions to contain the outbreak.
