2021-1-10，研究者们在专业刊物《柳叶刀》上发表的一篇论文中写道，肌肉疼痛、疲倦及恐惧、抑郁等心理障碍是感染新冠肺炎后最常见的长期后遗症。根据该文，住院治疗的新冠病人中约有3分之2在患病6个月后仍有一个或数个后遗症现象。

报告共同撰写人、中国医学科学院呼吸病学研究院副院长曹彬指出，研究表明，多数病人在治愈出院后至少还有某些染疫后遗症，说明了患者出院后继续疗治的 必要性，尤其是重症患者。

专家们研究了从2020年1月7日到5月29日从武汉金银潭医院治愈出院的共1733名感染者的情况。患者平均年龄57岁，52%为男性，48%为女性。他们当中的绝大多数（1172人）曾需供氧。6月中旬至9月初，病人再次接受调查。经由问卷、实验室及延续测试等手段，76%的被调查者仍至少呈现一种与染疫相伴的症状。

后遗症：疲倦虚弱

63%的被调查者告知有疲倦感或肌肉无力感，26%的人难以入睡，23%的人有恐惧感或抑郁症状。研究人员们发现，出现心理问题的女性多于男性。

实验室检测结果还显示，13%的病人在住院期间肾功能正常，但现在肾功能减弱。曾经出现重症的病人在出院数月后，依然显示肺功能弱化，身体供氧不佳。

中国研究人员的这一结论印证了迄今有关新冠肺炎长期后遗症的其他研究。不过，有科学家指出，该项研究报告中有若干不足。

比如，慢性肺炎和心脏病患者在被调查群体中占比相对较小。而且相关数据并非基于专家的调查结果，而是来自患者自己提供的信息。这可能导致错误评估。

另外，症状轻微的染疫者未成为受调查群体，原因是他们根本就没有被送入金银潭医院，而是在所谓的“方舱医院”治疗。

2021-1-10，美国智库兰德公司流行病学家博士说，要和病毒长期共存，首先必须确保医疗系统不会崩溃，她对此提出三点建议。

她说：“第一点就是灵活机动，运筹帷幄。现在我们看到医疗系统不光是内科医生、传染科医生来治疗新冠，基本上所有的医生护士都在做这个事情。所以这样的话，我们知道像眼科、外科的医生也在治疗新冠病人。我们一定要增加医生之间的交流，很多医院每天有很多对抗新冠的一些新的方法，所以这些都是很好的建议。”

她指出，第二个关键是疫苗、单克隆抗体等预防性治疗要跟上。她强调，单克隆抗体是唯一在不住院情况下，能减轻病人症状，挽救住院重症病人的药物。不过她遗憾地说，虽然联邦政府提供了这样的药品，但是很多医生都不知道怎么来用，或者从哪里得到这种药物。

她的第三点建议是，一定要注意医生和护士在心理和身体上的需要。她说：“在长期的重负荷下，一定要保护医生、护士有时间休息，并且有心理上的支援。”

博士说，由于新冠感染人数很多，病毒变异速度也会加快，疫苗更新至关重要。

她说：“从长远来说，新冠病毒越来越像流感病毒，每年它都会有新的变异，一定要密切关注。另外也要对治疗，还有预防，包括疫苗的更新都要跟上。在某种程度上，我们要用怎么对待流感病毒的方法来对待新冠病毒，有可能每年，甚至每几个月我们都要考虑一个新的疫苗。”

2021-1-10，汇整官方数据显示，截至格林威治标准时间9日11时，全球至少191万4057人死于2019冠状病毒疾病（COVID-19），至少8882万4680 例确诊。

搜集各国当局和世界卫生组织（WHO）提供的数据做出统计，但这恐怕只是实际感染总数的一部分，因为许多国家只检测有症状或症状最严重的病例。

全球8日通报新增1万4997人病殁、81万6686起确诊病例。根据通报数据，新增病殁人数最多国家依序为美国（3676死）、英国（1325死）与德国（1083死）。

美国仍是疫情最严重国家，累计36万8932人病故、2187万0988例确诊。

其他疫情严重国家还包括巴西（20万1460人丧生、801万3708例确诊）、印度（15万798人丧生、1043万1639例确诊）、墨西哥（13万2069人丧生、150万7931例确诊）及英国（7万9833人丧生、295万7472例确诊）。

依照染疫死亡数占人口比例，比利时是死亡率最高国家，每10万人就有172人染疫丧命；接下来依序为斯洛维尼亚（142人）、波士尼亚与赫塞哥维纳（131人）、义大利（129人）、北马其顿共和国（124人）。

从区域来看，欧洲累计61万3718死、2855万5903例确诊；拉丁美洲和加勒比海地区累计52万6000死、1631 万8970例确诊；美国和加拿大共计38万5581死、2251万2961例确诊。

亚洲共计22万4648死、1424万5502例确诊；中东地区共计9万1709死、417万1636例确诊；非洲共计7万1456死、298万8421例确诊；大洋洲共计945死、3万1294例确诊。

London’s mayor declared the capital’s Covid-19 situation to be critical Friday, reflecting deteriorating conditions for beleaguered hospitals, as the country recorded its highest daily death toll in the pandemic.

The grim news that another 1,325 people had died within 28 days of a positive test came hours after the UK regulator authorized a third vaccine for emergency use. The figure brings Britain’s official death toll from the coronavirus to 79,833, the highest in Europe. Not all the deaths announced by the government on Friday occurred on the same day.

London Mayor Sadiq Khan declared a “major incident, as the rapid spread of the virus pushed hospitals to breaking point, with the number of hospitalized coronavirus patients up 27 per cent in the week to Jan. 6. One in 30 people in Britain’s capital was infected with the virus in the week to January 2, according to the Office for National Statistics.

Other emergency services are also under strain, with hundreds of firefighters now driving ambulances, for example.

“Our heroic doctors, nurses and NHS staff are doing an amazing job, but with cases rising so rapidly, our hospitals are at risk of being overwhelmed, Khan said. “The stark reality is that we will run out of beds for patients in the next couple of weeks unless the spread of the virus slows down drastically.

A major incident is defined as one in which there is a risk to life and welfare and is “beyond the scope of business-as-usual operations. It allows coordination between different emergency agencies and will let London ask for help from other areas.

Khan, a member of the opposition Labour Party, also wrote to Conservative Prime Minister Boris Johnson asking for more financial support for Londoners who need to self-isolate and are unable to work, and called for masks to be worn in crowded outdoor spaces as well as indoors.

The action comes as more good news on fighting the virus appeared with the approval of the Moderna vaccine as the country ramps up an inoculation program critical to lifting the UK out of the pandemic.

The Department of Health said Friday that the vaccine meets the British medicines regulator’s “strict standards of safety, efficacy and quality.” Britain has ordered 17 million doses set to be delivered by the spring.

“Vaccines are the key to releasing us all from the grip of this pandemic, and today’s news is yet another important step towards ending lockdown and returning to normal life,” Business Secretary Alok Sharma said.

So far, Britain has inoculated 1.5 million people with the Pfizer-BioNTech and Oxford University-AstraZeneca vaccines. It plans to vaccinate some 15 million people by mid-February.

The authorization comes as the need for such help grows ever greater.

NHS England Chief Executive Simon Stevens said Thursday that the pressures facing hospitals in London and the southeast of England are so acute that a temporary field hospital at the ExCel London conference center will be opened next week.

The hospital was one of several built in the spring to help during the pandemic, but was not heavily used.

“The entirety of the health service in London is mobilizing to do everything it possibly can, but the infections, the rate of growth in admissions, that is what collectively the country has got to get under control,” Stevens said.

The NHS, short for National Health Service, announced Friday that its doctors and other medical personnel would soon be able to get vaccinated, a reflection of concern that absences caused by health workers needing to self-isolate were straining the system. Priority for the first shots previously was given to the most vulnerable in British society, such as those in care homes.

“For frontline staff who are risking their lives every day to keep patients safe, this announcement couldn’t have come soon enough, said Dr Samantha Batt-Rawden, president of the Doctors’ Association UK. “Tragically, we have lost too many healthcare workers to Covid in the UK. Frontline NHS and care workers absolutely must be protected as a matter of priority.

The UK is recording virus-related deaths at a level last seen during the worst days early in the pandemic. Friday’s toll surpassed the previous high of 1,224 deaths in April.

According to figures compiled by Johns Hopkins University, the UK has the most Covid-related deaths in Europe and the fifth-highest number in the world.

In promising coronavirus news, researchers at the Johns Hopkins Bloomberg School of Public Health have found that, contrary to widespread fears, patients on immunosuppressive drugs are not at higher risk from severe Covid-19.

Immunosuppressed patients are typically classed as those taking medications to prevent organ rejection following transplant or to treat a variety of inflammatory or autoimmune diseases and conditions. Roughly 10 million people in the US alone would fall under this category.

The medical status has been touted as a potential risk factor throughout the pandemic, with patients advised to ‘cocoon’ or practice a more extreme version of social distancing in order to better protect themselves from contracting the coronavirus.

This new research indicates they may be at no more risk than others, as immunosuppressed patients do not generally experience worse outcomes when hospitalized for severe Covid-19.

The researchers analyzed the anonymized records of 2,121 hospitalized Covid-19 patients admitted to Johns Hopkins facilities in Baltimore, Maryland and in Washington DC, between March and August 2020. Some 108, or about 5 percent, could be classified as immunosuppressed.

The team found that, on average, immunosuppressed patients did not experience worse health outcomes than other Covid patients, both in terms of length of stay, duration of ventilator use, or death in hospital.

“There has been concern that immunosuppression might be an important risk factor for severe COVID-19, but reassuringly we found no sign of that,” says study first author Kayte Andersen, a Ph.D. candidate in the Bloomberg School’s Department of Epidemiology.

Indeed, anecdotal reports from hospitals across the world have indicated the possibility that immunosuppressant medications may actually quell the so-called ‘cytokine storm’ which can overwhelm patients’ immune systems during severe cases of Covid-19.

In other words, rather than a hindrance, immunosuppressant medications may provide some form of protection against extreme Covid-19 infection.

The research team has now expanded the scope of their work to the national level, in the hopes of gaining more precise insights into the mystery surrounding immunosuppression and Covid-19.

“At this point, there is no indication that people taking immunosuppressive drugs for other diagnosed conditions should be concerned that their medication increases their risk for severe COVID-19,” Andersen says.
