我把昨天和今天报告的更新部分放在前头来了
----------------------------------
意大利死亡分析总结:
1)医疗被击穿后死亡率是10%,武汉、意大利、西班牙、法国都已验证(见我昨天微博或整份报告link);
2)3月底意大利累计死亡1.6万,4月底22万,(在4月1日全意大利禁止出门的严苛措施假设下);
3)意大利4月1日每日死亡数超2000,4月10日时超5000,4月底1万。注意,是每天...
----------------
呼喊:
下面是我做的意大利死亡回归和预测。其他欧美各国情况基本是类似。法国和西班牙的医疗逐渐被击穿,当期死亡率上升到5.8%和7.6%了,意大利10.2%。我实在没时间每个国家都做一遍。我每天5个小时睡眠,剩下都在拼命做了.......
我希望欧洲、美国等国家,能有影响力的人看到这个报告,能反应过来现在采取的措施还远远不够!
如果他们早一天能明白,采取对的措施,就能每个国家多救几万条人命!
-------------
图7-1 我用3月1日的确诊人数,和我根据意大利隔离“模式”猜测的日复增长率,推导了紫色的感染人数曲线。往前推迟10天,就是我预测的意大利确诊人数曲线。结果和真实确诊人数几乎吻合。
图7-2 3月5日时,重症病人已经击穿伦巴第重症医疗。3月17日时,已经击穿整个意大利的重症医疗。(新闻有)。“真实死亡率”(死亡的分子,对应是同期感染人的分母,而不是除其他的感染人分母,会导致死亡率初期低估),也从5.0%,攀升至10%
图7-3 我用前面推导的感染人数,延迟20天(死亡的人从感染到死亡的时间),乘上图2对应的死亡率,得到棕色的我预测的死亡人数。结果预测的死亡人数,和真实死亡人数几乎吻合。
图7-4 真实死亡数对比我预测的死亡人数,在标准坐标系里
图7-4-2 我把接下来几天的死亡数预测表格列出
图6 (7-5)我预设了4月1日意大利能反映过来,要做到全国每家绝对禁止出门,政府配送物资到门,才能进一步拉低传播,拉低日复增长率。(但也许他们现在还没搞懂,继续松垮隔离......结局会更惨)那么画出到4月底感染人数曲线(3月底感染85万,4月底感染480万)。然后如前述方法做出死亡人数预测,到4月底累计死亡22万...
图7 (7-6)对应的每天死亡人数曲线
武汉的死亡率分析:
我合理猜测的结论:
  • 对于没有医疗干预的感染者,从感染,到死亡大约20天
  • 对于没有医疗干预的感染者,死亡率10%

Death rate analysis of Wuhan
As below, it's only my of my guess, tring to explain the data and reason. It's not the 100% proven fact. But for me, this guess quite make sense.
My reasonable guess:
  • 20 days for a person from getting infected to death without enough medical treatment
  • Use 10% or maybe a little lower like 7%, as death rate without enough medical treatment

What should US do RIGHT NOW?
At this moment, the US country is take actions randamly with some areas following 2) Social Distancing 2, while others following 3) Panic Home Isolation 1, shown in our Chart of 13 Suggested Measures, and all thses two fall in the category of Majority Without Mask.
Daily growing rate will maintain at 18.6% with monthly multiple of 21x. All these measures are far from holding virus spreading and rapid increase of infected population.
First of all, the Goverment should make clear of overall statistics of the infected people (It is estimated to have 138,000 infected by today of March 20th.), and of the situation of rapid spreading (Nowadays, the crazy spreading is still proceeding everyday at about 30% of daily growing rate, relating with monthly multiple of 2600x ! )  I t should be adequitely aware of definite infection of a huge  population afterwards, with medical resources  breakdown, mortality rate increasing dramatically above 6%, and the reality of death of large population within a short period of time.
America will be shown as an example, and other cuntries could follow the simillar strategies.
The strongest strategy needs to land immediately and reduce the coronavirus spreading immediately
  • The regions in the United States that do not follow strict rules today are doing 2) Social Distancing  2; And some regions are doing 3) Panic Home Isolation 1 (both definitions assume the most citizens without wearing mask), the daily growth rate will still be 18.6%, which means the infected people will rise to 21 times monthly. It is definitely far from enough to stop the spread of the virus and the number of infections will increase dramatically!
  • Announce a State of WAR immediately, and soon the whole society will do 4) Complete Isolation. Stop almost all indoor offices, factories, schools; And stop almost all offline retail, catering, entertainment, services, aviation, public transportation with  confined spaces; And stop almost all other situations that cause people gathering in order to stop the spread of the virus;
  • Correspondingly the society goes into the most stringent solution immediately of 4) Complete Isolation 3 (All the citizens were isolated indoor, all the materials were delivered to the families and square cabin hospital isolated all the mild and suspected cases, in Wuhan, China during that critical period  of time.). At least, it should be done to 4) Complete Isolation1 immediately, to block social spreading, but bear the result of continuous double transmission in the family.
  • Build square cabin hospitals immediately to isolate people with mild illness.
  • Mobilize the mainstream media to adequately publicize the harmness of the virus to cause appropriate panic, and establish a proper understanding of knowhow to avoid infection, including wearing a mask to avoid contact to the greatest extent. Infected people at home are immediately isolated from each other. Those people who are having symptoms, or who might contact the infected person, need to get tested immediately. Appropriate panic allows people to stay better at home, and to keep people from being further infected with as few government-enforced resources costs as possible. Tell people why should do rather than what to do. 
  • Getting masks for the American people, only one mask per person even for repeated use is better than nothing whether by importing or building mask factories.
  • Establish simple shelters to house tramps to block their possibility of spreading the virus.
Guarantee the most basic supply of subsistence materials under social stagnation and maintain social order.
  • Mobilize the army and police to maintain social order, secure of materials transportation (especially food and medicines), and do not allow people to go out shopping, especially if everyone has no masks.
  • If the supplies are not enough, in order to avoid the situation that some people have no food after the panic and looting, the government needs to temporarily change to a rationing system to ensure that noone would  starve to death.
  • Equip the military and police with adequate medical protective equipment to avoid their infection to  the greatest extent as possible. If they collapse, social order will collapse, and the supply of living materials will collapse as well. If people are forced to go out to get food, and the coronavirus would not be controlled. And then there must be plenty of terrible violence happened.
  • When most industries are completely shut down, the bottom line is to guarantee the operation of civilian production, such as food, medicine, water, electricity, natural gas, and so on. The law State of WAR is needed to enforce them to keep running. But the premise is to distribute enough coronavirus isolation supplies (masks, goggles, gloves, disinfectants) to protect the corresponding workers. Prevent the collapse of the basic civilian production industry after their infection and collapse.
  • Trace the infected patients closely. After they are rehabilitate and able to work, dispatch them to the most critical civilian industry.
Safeguard the medical system and keep it running in case of breakdown
  • Do everything possible to get more medical protection supplies to protect doctors and nurses fighting on the front line. They should not be sacrificed. Otherwise, national confidence collapses immediately.
  • Use the law of State of WAR to temporarily take over private hospitals as state-owned, temporarily requisition private doctors and nurses. Prepare as much medical resources as possible, and delay the day when the medical system is broken down.
  • Get more ventilators and other equipment for the hospital.
  • Prepare medical resources, such as ICU as soon as possible. After medical system is punctured, do not let critical  patients who cannot be treated go home. Establish places of hospice to 1) comfort life, 2) stop them spreading the virus at home; 3) prevent them from being overly emotional and retaliating against society and medical personnel.
美国现在应该做什么:
  • 首先政府必须搞清楚病毒当前在美国的感染人数情况(3月22日已经有29万感染者),和快速传播的情况(今天还在以以每天30%左右的日复增长率在疯狂传播,对应月复倍数2600x)!充分意识到接下来一定是大量人口感染,医疗资源被击穿,死亡率快速上升到6%以上,大量人口短时间死亡的现实。
  • 能充分意识到,每种不同的策略和民众行为,在一个月以后会产生什么结果。意识到今天美国这种松散的部分地区2)减少社交2,和部分地区 3)居家隔离1 的隔离程度(两者定义都涵盖主流民众不戴口罩),日复增长率将仍有18.6%,月复倍数21x。是远远不够阻断病毒传播和感染人数暴增的!充分意识到只有 4)完全隔离3(需要方舱医院)才能真正阻断病毒传播。再不济,也要做到4)完全隔离1,但4月底感染人数是前者的2.5倍。
  • 能把国家目标从美好的幻想,如保障经济,保障就业,救治感染者等,调整到合理的目标:能阻断病毒无限传播到所有人,百万计病亡的能善终,没感染的百姓不饿死,绝望的感染者和没食物没收入的民众产生的动乱能控制下来,美国国家机器不崩溃。当然药品和疫苗不需要我提醒。
  • 我这里举美国例子来说,其他国家策略基本相同;
Do's
需要最强策略立即落地,马上降低病毒传播
  • 今天美国这种松散的部分地区2)减少社交2,和部分地区 3)居家隔离1的隔离程度(两者定义都涵盖主流民众不戴口罩),日复增长率将仍有18.6%,月复倍数21x。是远远不够阻断病毒传播和感染人数暴增的!
  • 立即宣布进入战争状态,很快做到全社会 4)全面隔离。停止几乎所有室内办公、工作,停止学校,停止线下零售、餐饮、娱乐、服务,停止航空、密闭空间的公共交通,以及其他所有导致人员聚集传染的情况;
  • 对应马上立即进入最严格的 4)完全隔离3,(武汉全员隔离不出门 + 物资外部配送到门 + 方舱医院隔离疑似&轻症)。再不济也要立即做到 4)完全隔离1,至少阻断社会传播,但承受家庭内持续翻倍传播的结果。
  • 立即建设方舱医院,马上隔离轻症的人;
  • 调动媒体,足够程度宣传病毒的危害,引起适当的恐慌,建立起应该如何避免感染的正确认识,包括戴口罩,最大限度避免接触,家里有人感染立即互相隔离,有症状,或有怀疑和潜在感染者接触,就立即去做检测,等等。适当的恐慌能让民众较好地呆在家中,在尽可能少政府强制实施资源成本的情况下,仍能保持民众少被进一步感染。not tell them what to do, but why to do;
  • 为美国人民弄到口罩,每人1个反复用也比没有强。不管是进口还是去建设口罩厂;
  • 建立简易场所收留流浪汉,阻断因此传播病毒的可能;
保障在社会停摆下的最基础的生存物资供应,以及维持社会秩序
  • 调动军队和警察,来维持社会秩序安全和生活物资运转(尤其是食物和药品),不能让民众出门去购买,尤其在大家都没口罩的情况下;
  • 如果物资不够,为了避免恐慌哄抢后,部分人什么食物都没有的情况,政府需要临时强制改成配给制度,保证每个人不会饿死;
  • 为军队和警察,配上足够好的医疗防护用品,最大可能避免他们的感染。他们如果崩溃,社会治安会崩溃,生活物资的供给会崩溃。民众被迫出门去获取食物,病毒传播就无法控制。且一定会发生大量暴力事件。
  • 大部分产业全停摆的情况下,最底线保障民生产业,如食物,药品,水,电,天然气,等等的运转。需要动用战争法强制他们保持运转。但前提是发放足够的病毒隔离用品(口罩、眼镜、手套、消毒),保护相应劳动者。防止他们感染崩溃后社会基本民生产业的崩溃。
  • 定向追踪感染,但最后康复免疫的劳动力,将他们调度到最关键的民生保障产业;
保障医疗系统,在被击穿的情况下,维持运转
  • 想尽一切办法弄到更多的医疗保护用品,保护在前线作战的医生护士,他们不能牺牲。否则国家信心立即崩溃;
  • 用战争法,临时征用私立医院为国有,临时征用私人医生和护士,尽可能多的筹备医疗资源,让医疗系统被击穿的这一天来得晚一点;
  • 为医院弄到更多的呼吸机等设备;
  • 准备医疗资源如ICU被击穿后,不要把无法收治的重症病人放回家。建立临终关怀的场所。起到:1)抚慰生命、2)停止他们继续回家传播;3)防止他们情绪过激做出报复社会、医护人员的行为;
12)
那隔离之后是否就会到拐点,什么时候疫情会过去?
首先在四月份核心看的是欧美国家到底采取什么样程度的隔离措施。是3)居家隔离2,3)居家隔离3,还是4)完全隔离1,还是4)完全隔离4。这四者有天壤之别。导致的结果差别是8千万感染,3千万感染,还是5百万感染。但不论是哪种,重症病人都是会远远击穿医疗资源,死亡率6%打底,因此前面的 感染人数 X 死亡率,就是随后的地狱结果。
但不管是哪一种,接下来的情况是在疫苗出来之前,所有百姓看到大量的感染、医疗系统挤兑、病亡案例,都会陷入恐慌,怕死,死死躲在家。不论政府是否允许或者鼓励去工作,整个办公室的工作、零售、学校、公共交通、航空都是不可能开展的。除了少数民生基础设施(食物、水、电、药品等),国家应该会投入全副防护的劳动力,以及已经感染康复免疫的劳动力来维持,其他在长达6个月以上的大部分社会经济活动停滞中,生活物资的保障和治安问题,是对非感染者的最大威胁。但整个国家必须经历这样的死守,不论是国家的意愿如何,百姓都会去死守,以这样的经济代价,来换得尽可能的生存和健康。
如果食物不是挨家定量配给,还是超市购买,那么1)超市是聚众抢购,“抢购”的意思是,“抢”会伴随着暴力。因为每个人是为了活命,都玩命要囤到6个月食物,而社会体系供给是不可能达到的。不要期待那时的道德或者社会秩序,排队就不要想了。2)超市聚众的感染不可避免,如果那时全美还没戴口罩,那去超市抢购真的是要赌上性命。武汉是很明白地做到食物挨家配给,但欧美会怎么样做,看他们了。
在海外的中国人,应该把2020的期望调到自己和家人能平安活下去:1)自己千万不要感染,如果感染就拼自己免疫力是否够,直白点是拼谁命硬了;2)能够获得食物,不被饿死;3)社会治安在可就是接受的范围内,没有遭遇枪支生命威胁(排华,和抢食物是必然不可避免地发生的);4)什么工作、收入、升迁、学位,这些事就不要YY了。面对死3%以上人口的“战争”,这些你届时也不会放在心上。
药只能救感染的人,但必须满足在家口服就能大幅降低死亡率,否则也没用。医院是不可能收得下95%的感染者的。疫苗才是真的救社会的东西,也许是6个月后,也许是9个月后。再更早时间去打的,可能是小白鼠了,疫苗也许有免疫效果,但副作用有可能1年后才出来,希望不会致命或致残。(不是吓大家,历史上多次出现过,所以疫苗研发出很快,但要大量临床试验,万无一失后才敢给大众注射。所以常见疫苗的有研发周期是10年~15年...)
如果你现在在海外,我建议你立即去1)囤至少6个月不出门不饿死的物资,新鲜食物和冷冻肉就别想囤够了,常温包装食品更能救你;2)想尽所有办法搞到武器自卫,再不济用我提的办法贴post blaffing威慑;3)中国人抱团居住,或就近居住,尤其是年轻女性!(我不愿看到印尼惨剧重演)中国人一定要团结起来,互相照应,才能挡住武装侵犯;4)不惜其他所有代价,避免自己被感染;5)加够汽油(车+桶),如果绝望中你还有撤侨机会,那能实现2千公里逃命,你心里就还有希望;
如果国家不希望经济完全停滞,或不接受社会在崩溃边缘的处境,那就可能会放弃严格的隔离措施,使得大量早期还未恐慌的民众在短时间内被感染。其中绝大部分人,特别是年轻人,都能够幸存下来,获得免疫力。从而重新投入到社会经济的运转中。这是英国提的“群体免疫”。但剩下有大比例的还未被感染的人口,即使是年轻人,即使是知道自己可能从统计意义上只有0.5%的死亡机率。他们也不会恢复到正常的工作中。没有人想在俄罗斯轮盘上赌命。经济还是会受到重创。但是会比前者略好一点。但对应的代价是大量人口,最少5000万以上,乘以6%以上的死亡率......如果年纪长者,在这个过程中能保护隔离得特别好,在他们6个以上完全不出门的情况下,获得食物配给,隔绝病毒传播,那么总体死亡率有希望大幅下降,但仍然至少是1%,2%这样的数字,乘上大几千万的人口,仍然是非常痛心的数字...
祈祷大家都能平安幸存下来!2020会很黑暗,死抗过去就好了!疫情总会终结,世界永远有希望!

怎么会有排华现象?你说得太吓人了,我这边社会治安一直很好啊
大家无法想象排华/仇华情绪会怎么样。我举个虚构的例子吧。
原来一个美国45岁的非亚裔中年男性,人很正常,原来还有得体的零售行业工作。3月22日店面关了。现在日期是4月底,他们家已经有1个月没有收入了。他没有存款。拿了政府的1000美金救济之后已经花完,现在没有钱买最基本的食物和药品。更不用说有钱付房租了。
昨天超市刚一补货,就上千个人去抢,他什么也没有抢到。
他的挚爱的父亲感染病毒,3周内从完全健康到去世。他的母亲也感染了,生命垂危,但是医院根本收不进,正在家等最后一刻的到来。他无法接受,但却什么也做不了。
他自己好像也感染了,咳嗽的非常厉害,呼吸很困难,很明确是重症。他去医院得不到检测,更不要说住院接受治疗。他看到周边相似症状的人没有得到治疗,三周内人就没有了。他被拒绝接受治疗,因为医院把床位让给了一个30岁的重症小伙子,因为那个可能能救活的概率更大一点。他完全不知道自己是否能活下去?虽然从统计上他这个年纪应该有95%的生存希望。
自己最爱的亲人,因病一瞬间就没了。他自己也生死未卜,得不到社会的关爱。没有钱也抢不到食物。他怨恨这个世界对他如此残忍。他接受不了这个现实。
人在遭遇悲惨的事情的时候,是不会认为是自己错,一定要对外归因,对外怪罪,心里才能接受。
他听到的,是整个国家都在说这一切都是中国害的,这是中国病毒。而他看到当地中国人早早都戴着口罩,大部分都没有被感染。而且他们也都比较有钱,早早的就囤积了足够的食物,也没有出来去抢购。似乎并没有遭遇他所遭遇的不幸。他感到非常的不公和愤怒。他看着还在剧烈咳嗽躺在床上的女儿。他决定拿起枪,去抢些食物回来活命。你觉得他会敲开谁家的门?
而且这种情绪,在一组有相同遭遇的人群中,会急速地获得本能性认同,和极高地被强化。如果他不是一个人,而是一伙儿人,都遭遇了如此人间惨剧。而他们都有枪,也都跟着国家老大,都认为错在中国,都是中国害的。并且他们求生欲巨大,必须去获得足够的食物来喂饱自己和孩子。而他知道中国人有积蓄,也囤积了足够的食物。你觉得他们会怎么做?
