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.

These are among the game-changers looming as we ring in the New Year.

《今日美国》(USA Today)说,对大多数城市来讲,就业复苏即使能实现,也得是在好几年过后。浏览知名分析师梅瑞迪斯?惠特尼(Meredith Whitney)新书《州的命运》(The Fate of States)时你会看到,她提醒说,“过多的养老金会挤出教育支出等自由派目标,也会挤出保守派希望实现的减税目标”。
明年就是这只会说话的萌熊诞生60周年了。为了纪念帕丁顿熊诞生60周年,曾执导2014年口碑和票房都大获成功的电影《帕丁顿熊》的保罗?金回归续集担任导演。在当前这个连儿童娱乐节目都充斥着黑暗和暴力的时代,我们比以往任何时候都需要这种安静地讲述英国普通人生活的片子。这部新电影的情节?事实上,没有太多情节:根据上部电影的结尾,帕丁顿熊现在和温莎花园的布朗一家舒适地生活在一起。他想从一个当地的书商那里给他的姨妈买一本立体书,但发现自己还差几英镑,于是他就穿上了自己的长筒雨靴和粗呢连帽外套,并找到了几份兼职工作——结果却发现这本书在书店被偷了!神秘的破案之旅(其实也没那么严重)就此开始。你在电影中还可以看到关于“橘子酱控”帕丁顿熊的更多笑话。该片将于11月10日在英国上映,11月23日在德国上映,11月30日在柬埔寨和马来西亚上映。(资料来源:欧映嘉纳)
