【武汉冠状病毒】病毒空气中可存活半小时 中国专家:传染范围达4.5米
中国政府流行病学家发现,武汉冠状病毒(Covid-19)病菌能够在空中徘徊至少30分钟,可传播至4.5米远,比世界卫生组织所建议的“安全距离”还要远。
研究员还发现,病菌可以透过呼吸飞沫降落到表面后存活数天,如果有不知情人触碰了后擦拭到脸部和手上,就还会增加传播风险。
报告指出,病菌在表面上存活的时间长短取决于温度和物件表面类型等因素,比如在玻璃、布料、金属、塑料或纸张上,在37摄氏的温度下,病菌可存活两至三天。
有关的研究报告来自湖南省的一组官方研究员,根据一起集群病例所进行的研究结果,并挑战世卫组织所提出的安全距离,即人们应该保持一至两米(三至六英尺半)。
建议常洗手和全程戴口罩
研究员于上周五在医药杂志《实用预防医学》(Practical Preventive Medicine)上发表了一篇论文,写到:“可以确定的是,在装有冷气(空调)的封闭环境中,冠毒病菌的传播距离将超过公认的安全距离”。
论文中还强调,即使在病原体(带菌人)离开了巴士,病菌仍然可能漂浮在巴士内。
研究员警告说,冠毒病菌也能在人的粪便或体液内存活超过五天。
他们说,这项研究证明了人们在公共场所洗手和戴口罩的重要性,因为病菌会在空气中徘徊,停留在细小液滴颗粒上。“我们的建议是,在乘坐巴士的路途中,始终戴着口罩。”
依巴士传染病例展开研究
他们的研究是根据于今年1月22日农历新年回乡高峰期间,在本地爆发的一起病例。
一名简称为A的乘客患者登上满客的长途巴士,在最后第二排坐下。当时A已经身感不适,但是因为中国那是还未宣布冠毒爆发是一场国家危机,因此A并没有戴上口罩,48座位上的大多数乘客和司机也没有戴口罩。
基于中国政府之前曾要求在全部长途巴士上安装闭路电视摄像机,因此这位研究员提供了宝贵的录像资料,重演了病毒在窗户紧闭巴士上的传播情况。
研究由湖南省疾病预防控制中心的胡世雄(Hu Shixiong,译音)领导。他指出,根据摄像录影显示,A在耗时四小时的旅程中,并没有和任何人互动。但是,当巴士抵达下一个城市时,冠毒病菌已经从A的身上,传染给车上的七名乘客了。
这七名被感染的乘客不仅包括坐在A附近的人士,也包括了数名乘坐在和A相距六排座位的乘客,即和患者距离约4.5米。七人后来全被检测出阳性结果,包括一名未出现任何症状的乘客。
下一班乘客受气雾剂影响感染
在这班乘客下车后,另一班乘客于约半小时后等上班时,但是,一名坐在国道另一侧前排的乘客被病菌感染了。
胡世雄指出,没有戴口罩的病患,很可能是吸入了由上一班乘客所遗留下来的气雾剂或细小颗粒,因而感染。气雾剂是轻质的颗粒,由微小的体液液滴所形成。“在一个完全封闭的空间内,气流主要靠冷气机产生的热空气驱动,热空气的上升可能将载有病毒的飞沫传播到更远的距离,形成了感染原因。”
A在下了长途巴士后,转乘小巴士,展开一个小时的旅程。路上,病毒又从A身上转染了给两名乘客,其中一名乘客和A所在的位置相距4.5米。
当研究于2月中结束时,患者A已经传染了至少13人。
人们普遍认为,冠毒病菌的空中传播受到限制,因为患者产生的微小液滴会迅速沉入地面。这信念促使中国卫生当局建议人们在公众场所时要保持一米的距离,美国疾病控制中心则建议安全距离为六英尺,即1.8米。
戴口罩乘客未受感染
研究也显示了,在两辆巴士上有戴口罩的乘客,均未受到感染,这说明了要求人们在公共场合戴口罩的决定是正确的。
“在乘坐封闭空间的公共交通工具(如地铁、汽车、飞机等)时,应该始终戴着口罩,同时尽量减少手和公共区域之间的接触,并且避免在洗手前触碰脸部。”
北京医生:尚有未解之谜
研究员们也建议改进公共交通的卫生条件,并调节空调,以为车内提供最大程度的新鲜空气供应量。
他们也促请当局,应该在公交内部进行每天一至两次的清理和消毒工作,尤其是在乘客抵达终点站后。
一位参与冠毒诊断和治疗的北京医生指出,有关的研究还存在一些未解问题,如乘坐在A患者身边的乘客,虽然曝露在携带病毒气雾剂可能性最高的范围内,但是并没有受到感染。
“我们对这种病毒传播的知识仍然有限。”

Chee Soon Juan questions Shanmugam’s $88 million property sale amid silence from Mainstream Media
Dr Chee Soon Juan of the SDP raised concerns about the S$88 million sale of Mr K Shanmugam’s Good Class Bungalow at Astrid Hill, questioning transparency and the lack of mainstream media coverage. He called for clarity on the buyer, valuation, and potential conflicts of interest.
On Sunday (22 Sep), Dr Chee Soon Juan, Secretary General of the Singapore Democratic Party (SDP), issued a public statement on Facebook, expressing concerns regarding the sale of Minister for Home Affairs and Law, Mr K Shanmugam’s Good Class Bungalow (GCB) at Astrid Hill.
Dr Chee questioned the transparency of the S$88 million transaction and the absence of mainstream media coverage despite widespread discussion online.
According to multiple reports cited by Dr Chee, Mr Shanmugam’s property was transferred in August 2023 to UBS Trustees (Singapore) Pte Ltd, which holds the property in trust under the Jasmine Villa Settlement.
Dr Chee’s statement focused on two primary concerns: the lack of response from Mr Shanmugam regarding the transaction and the silence of major media outlets, including Singapore Press Holdings and Mediacorp.
He argued that, given the ongoing public discourse and the relevance of property prices in Singapore, the sale of a high-value asset by a public official warranted further scrutiny.
In his Facebook post, Dr Chee posed several questions directed at Mr Shanmugam and the government:
- Who purchased the property, and is the buyer a Singaporean citizen?
- Who owns Jasmine Villa Settlement?
- Were former Prime Minister Lee Hsien Loong and current Prime Minister Lawrence Wong informed of the transaction, and what were their responses?
- How was it ensured that the funds were not linked to money laundering?
- How was the property’s valuation determined, and by whom?
The Astrid Hill property, originally purchased by Mr Shanmugam in 2003 for S$7.95 million, saw a significant increase in value, aligning with the high-end status of District 10, where it is located. The 3,170.7 square-meter property was sold for S$88 million in August 2023.
Dr Chee highlighted that, despite Mr Shanmugam’s detailed responses regarding the Ridout Road property, no such transparency had been offered in relation to the Astrid Hill sale.
He argued that the lack of mainstream media coverage was particularly concerning, as public interest in the sale is high. Dr Chee emphasized that property prices and housing affordability are critical issues in Singapore, and transparency from public officials is essential to maintain trust.
Dr Chee emphasized that the Ministerial Code of Conduct unambiguously states: “A Minister must scrupulously avoid any actual or apparent conflict of interest between his office and his private financial interests.”
He concluded his statement by reiterating the need for Mr Shanmugam to address the questions raised, as the matter involves not only the Minister himself but also the integrity of the government and its responsibility to the public.
The supposed sale of Mr Shamugam’s Astrid Hill property took place just a month after Mr Shanmugam spoke in Parliament over his rental of a state-owned bungalow at Ridout Road via a ministerial statement addressing potential conflicts of interest.
At that time, Mr Shanmugam explained that his decision to sell his home was due to concerns about over-investment in a single asset, noting that his financial planning prompted him to sell the property and move into rental accommodation.
Mr Shanmugam is said to have recused himself from the decision-making process, and a subsequent investigation by the Corrupt Practices Investigation Bureau (CPIB) found no wrongdoing while Senior Minister Teo Chee Hean confirmed in Parliament that Mr Shanmugam had removed himself from any decisions involving the property.
As of now, Mr Shanmugam has not commented publicly on the sale of his Astrid Hill property.

Redditors question support for PAP over perceived arrogance and authoritarian attitude
Despite Senior Minister Lee Hsien Loong’s warning that slimmer electoral margins would limit the government’s political space “to do the right things”, many Redditors questioned their support for the ruling PAP, criticising its perceived arrogance. They argued that SM Lee’s remarks show the party has ‘lost its ways’ and acts as if it alone can determine what is right. Others noted that the PAP’s supermajority allows for the passage of unfavourable policies without adequate scrutiny.
In a recent speech, Senior Minister Lee Hsien Loong warned that “if electoral margins get slimmer, the government will have less political space to do the right things.”
Mr Lee, who served as Prime Minister for 20 years, highlighted the risks associated with increasingly competitive politics.
“It will become harder to disregard short-term considerations in decision-making. The political dynamics will become very different,” he stated during his speech at the Annual Public Service Leadership Ceremony 2024 on 17 September.
“Singaporeans must understand the dangers this creates, and so must the public service,” SM Lee stressed.
SM Lee pointed out that Singapore faces formidable internal and external challenges in the years ahead, with rising expectations and demands from citizens.
As growth becomes harder to achieve and politics becomes more fiercely contested, he warned, “Things can go wrong for Singapore too.”
He urged vigilance in preparing for an uncertain future, noting, “As the world changes, and as the generations change, we must do our best to renew our system – to ensure that it continues to work well for us, even as things change.”
Critique of PAP’s Arrogance and Disconnect from Singaporeans
The People’s Action Party (PAP) experienced a notable decline in its vote share during the 2020 General Election, securing 61.24% of the votes and winning 83 out of 93 seats, a drop from 69.9% in 2015.
A significant loss was in Sengkang GRC, where the PAP team, led by former Minister Ng Chee Meng, was defeated by the Workers’ Party (WP).
In discussions on Reddit, some users questioned why they should support the ruling PAP, criticising the party’s perceived arrogance.
They pointed out that SM Lee’s recent remarks illustrate that the party has strayed from effectively serving Singaporeans and seems to believe it has the sole authority to decide what is right.
Others highlighted that the PAP’s super-majority in Parliament enables the passage of unfavourable policies without sufficient scrutiny.
One comment acknowledged that while many older Singaporeans remain loyal to the PAP due to its past achievements, younger generations feel the party has failed to deliver similar results.
There is significant frustration that essentials like housing and the cost of living have become less affordable compared to previous generations.
The comment emphasised the importance of the 2011 election results, which they believe compelled the PAP to reassess its policies, especially concerning foreign labor and job security.
He suggested that to retain voter support, the PAP must continue to ensure a good material standard of living.
“Then, I ask you, vote PAP for what? They deserve to lose a supermajority. Or else why would they continue to deliver the same promises they delivered to our parents? What else would get a bunch of clueless bureaucrats to recognise their problems?”
Emphasising Government Accountability to the Public
Another Redditor argued that it is the government’s responsibility to be accountable to the people.
He further challenged SM Lee’s assertion about having less political space to do the right things, questioning his authority to define what is “right” for Singapore.
The comment criticised initiatives like the Founder’s Memorial and the NS Square, suggesting they may serve to boost the egos of a few rather than benefit the broader population. The Redditor also questioned the justification for GST hikes amid rising living costs.
“Policies should always be enacted to the benefit of the people, and it should always be the people who decide what is the best course of action for our country. No one should decide that other than us.”
The comment called for an end to narratives that present the PAP as the only party capable of rescuing Singapore from crises, stating that the country has moved past the existential challenges of its founding era and that innovative ideas can come from beyond a single political party.
Another comment echoed this sentiment, noting that by stating this, SM Lee seemingly expects Singaporeans to accept the PAP’s assumption that they—and by extension, the government and public service—will generally do the “right things.”
“What is conveniently overlooked is that the point of having elections is to have us examine for ourselves if we accept that very premise, and vote accordingly.”
A comment further argued that simply losing a supermajority does not equate to a lack of political space for the government to make the right decisions.
The Redditor express frustration with SM Lee’s rhetoric, suggesting that he is manipulating public perception to justify arbitrary changes to the constitution.
Concerns Over PAP’s Supermajority in Parliament
Another comment pointed out that the PAP’s supermajority in Parliament enables the passage of questionable and controversial policies, bypassing robust debate and discussion.
The comment highlighted the contentious constitutional amendments made in late 2016, which reserved the elected presidency for candidates from a specific racial group if no president from that group had served in the previous five terms.
A comment highlighted the contrast: in the past, the PAP enjoyed a wide electoral margin because citizens believed they governed effectively. Now, the PAP claims that without a substantial electoral margin, they cannot govern well.
