中国建材行业一周大事记(11.23-11.27)

The UK is one of the countries most severely affected by covid-19. Recent outbreaks in English towns such as Oldham, probably involving transmission within large multigenerational households, show the importance of getting the right public health measures in place now to prevent more widespread surges in infections.1

Current test and trace policies have mainly focused on preventing spread in care homes, hospitals, and in the community.2 However, contact within households is thought to be responsible for roughly 70% of SARS-CoV-2 transmission when widespread community control measures are in place.3 In Wuhan, the reproduction number (R) dropped from 3.54 to 1.18 after lockdown and cordon sanitaire. But the epidemic was only brought under complete control when Fangcang (field) hospitals were introduced to isolate cases outside the home, with R dropping to 0.51 after two weeks.4

Current UK guidance advises household contacts to isolate within the same home as the index case for 14 days.5 They make up the majority of contacts for infected individuals and are likely to remain exposed to the infected household member during this period of isolation.6 Despite guidance advising household members to socially distance, contacts are likely to interact repeatedly—during mealtimes, for example—and to share facilities such as bathrooms.

We know that transmission is more likely to occur indoors than outdoors.7 The cumulative risk to household contacts from an infected person is likely to be substantial during peak viral shedding. In one study in New York State, 38% of household contacts tested positive for SARS-Cov-2, and similar secondary infection rates have been reported in China.89 Transmission may be even higher among household contacts of essential workers, who are at greater risk of being infected than the general population.10

Household members who are older, have underlying medical conditions, or share a bed or vehicle with the index case are the most susceptible.91112 Children seem to be at lower risk of being infected.13 However, their stool samples and nasopharyngeal swabs can remain positive for SARS-CoV-2 for more than two weeks after symptom resolution,14 although their role in transmission remains to be established.

Governments should consider new public health measures to prevent household transmission as we prepare for a potential second wave. Household quarantine is likely to remain an important pandemic control measure, and government support for people quarantined at home is conspicuously absent in the UK: this position has been challenged by independent experts.15

Effective isolation

Effective isolation of index cases from household members could reduce secondary infections.12 Wearing masks within quarantined households may help, particularly if used by the index case as soon as infection is suspected.16 The World Health Organization recommends that infected people and unavoidable close contacts, particularly those in vulnerable groups, should wear medical masks, but Public Health England does not currently recommend this. Other measures that should be considered (and evaluated) include clear advice on enhanced personal hygiene; cleaning and disinfecting shared toilets and other common spaces, door handles, and touch points; and staggering mealtimes.

People who are unable to self-isolate safely at home could be accommodated in special isolation facilities such as hotels and hostels, an approach adopted by some other countries, including Italy, Finland, and Lithuania.17 In China, field hospitals were created to manage and strictly isolate patients with mild-to-moderate covid-19.18 Nightingale hospitals in the UK could be similarly repurposed to support isolation of infected people with mild-to-moderate disease. As medical and nursing care needs are mostly modest, the cost would be relatively low. However, such a system depends on access to rapid testing for anyone with symptoms or possible exposure so that infection can be confirmed and isolation started before transmission occurs. It would also require public trust that isolation in these facilities would be voluntary, safe, and supportive.

首先,我们来回顾一下这些南美国家吧。东道主巴西队肯定是第一个要提到的。时间倒流18个月,巴西在这段时间一直在努力,但是对人称“大菲尔”(Big Phil)的斯科拉里(Scolari)的任命起到了作用。他让球队重新拾回失去的信念。在2013年联合会杯决赛中,3:0大胜西班牙的战果让诸多专业人士震惊,也在突然之间,巴西让人们对他们寄予了厚望。虽然你无法驳斥这样的比分,但是我们依旧想知道巴西是否有实力赢得此次世界杯。人们预计,内马尔(Neymar)也将放出“魔法”大招,但是他们还是想依靠弗雷德来进球。这不是对弗雷德无礼,不过,在1994以及2002年,巴西之所以能够赢得世界杯还是依靠于罗纳尔多和罗马里奥领衔前线的成功,而这两位也被誉为世界杯的传奇人物。

  • Salary three years after graduation and salary increase are the main criteria, each accounting for 20 per cent of the ranking’s weight. Most schools in the top 25 score well on at least one of these criteria. The top 10 schools would mostly also rank in the first 10 if salaries and their increases were excluded. The only exceptions are Nanyang Business School and China Europe International Business School, both underperforming in the doctoral and research ranks.

Inflation (and deflation) won't rear its ugly head Surging oil production — along with slower global growth — has caused the price of petroleum to collapse from more than $100 a barrel last summer to barely $50 a barrel at the end of 2014. The effect has been to reverse an uptick in U.S. inflation earlier in the year.
