浙江“以房养老”个案诞生 房子扮演了怎样的角色

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.

有些热门剧已经走得太远,应该降降温了,却仍在大张旗鼓,比如《唐顿庄园》(Downton Abbey)、《丑闻》(Scandal)和《复仇》(Revenge)。ABC频道的新剧《逍遥法外》(How to Get Away With Murder)是一部有趣的替代品,它是一部耸人听闻的夜间肥皂剧,讲述不法辩护律师的故事,简直可以称为“法律与无序”。

It's a bit of a lark organised by UK film critics – a gong for the top canine performance at the festival, handed out on the last Friday in the British pavilion. This year the Palm Dog went to Lucky, a Maltipoo – that's half Maltese terrier, half poodle – who plays Dixie in Miguel Gomes' six-hour epic, Arabian Nights. The prizewinner is presented with a toy bone and this year delivered a brief acceptance speech (“woof”) by video link. A jolly time was had by all but an unnamed French journalist felt that the award was “an unwanted intrusion of British silliness” in the glamorous proceedings, according to AFP. “From the French perspective, this is a bit bizarre,” he is reported to have said. “The British are weird.”

It was the first "real" James Bond song (again, the first two films only opened with orchestral music), and it's still the best. Shirley Bassey got an opportunity to sing her soul out and she accepted the challenge with obvious pleasure. This is a song that makes the villain Auric Goldfinger seem a lot more threatening (and attractive) than he actually is, but that's part of the miracle of Bassey's work here. It's proud and heroic and enticing and it's kind of a lie, but who cares? The music is pure James Bond, the lyrics are pure machismo, and the performance is perfect.
“It is exceptionally unlikely that we would be witnessing a record year of warmth, during a record-warm decade, during a several decades-long period of warmth that appears to be unrivaled for more than a thousand years, were it not for the rising levels of planet-warming gases produced by the burning of fossil fuels,” Michael E. Mann, a climate scientist at the Pennsylvania State University, said in an email.

因此,有如此强大的南美洲队伍坐镇,主要的挑战力量将来自何方呢?嗯,来自欧洲的强势力量恐怕便是最显而易见的答案了,你还能去哪里寻找一个比西班牙更有冠军相的球队呢?作为一支卫冕冠军,并坐拥两届欧锦赛的冠军头号,这是一支不仅知道如何出色发挥,同时知晓如何赢得比赛的队伍。因此,虽然梅西和罗纳尔多曾获得所有年度最佳球员的头衔,但是哈维(Xavi)和伊涅斯塔(Iniesta)却将所有主要冠军据为己有。那么,他们在2014年将延续冠军生涯么?对于这个困扰世界上其他国家的问题,答案是肯定的。不仅大多数老将依然坚守岗位,许多包括科克(Koke )和蒂亚戈·阿尔坎塔拉(Thiago Alcantara)等有才华的年轻球员也加入了。不仅仅如此,他们还从东道主的眼皮下挖走了一个才华横溢的射手蒂亚戈·科斯塔(Diego Costa)收入囊中,因为这位马德里竞技(Atletico Madrid)的前锋选择为西班牙效力,而非自己出生国家踢球。
