看意大利媒体说模型预测疫情在3月18号达到高峰。4月25之后情况是大大好转。希望模型好用啊。bless

EPIDEMIOLOGICAL FORECASTS
March 16, 2020That's when the peak comes and when the emergency ends, according to government estimatesThe technical report of the emergency decree foresees that in two or three days we will reach the maximum of the infected. Then there will be a slow descent until April. If all goes well, if everyone follows the rules, the release from the virus will come on April 25th。
Good, for the moment, there are the numbers of the infrastructures. In Lombardy, intensive care beds have reached 1,200, as stated by the councilor for health Giulio Gallera, of whom 924 are occupied. All other figures, now, do not encourage: the infections have increased and reach 20,603, while the dead are 1,809 and the recovered (luckily more) are 2,335.
When it will end? Difficult to say. Maybe in late April. As has been reported in some newspapers in recent days , the government's official forecast, contained in the technical report of the third emergency decree, places the peak, that is, the highest point of the ascending curve of the infections, on March 18. Two days still. The estimate, they explain, is based on the trend of the infections up to March 8 and elaborates a forecast for the following days, with a doubling and then a gradual decrease that would be due to the containment measures. In the end, a total of 92 thousand infections would be reached. At the moment, it seems that the numbers are correct: for March 15 the estimates spoke of 3,500 new cases and 3,590 were counted. For today, March 16 should be less than 4 thousand. If the trend follows the forecasts, also in light of the restrictive measures taken by the government crossed at the incubation periods of the infection, the emergency will be considered exhausted for April 25th. Again, a fateful date for Italy. In any case, it is better not to have excessive hopes. In the South, based on the trend of the spread of Lombardy, they expect the respective peak around late March and early April. But the worries are growing: if the Lombard numbers were verified, the health system would collapse. The hope is that the rush to sleep in the last few days - it is expected to add five thousand across the country in less than 45 days - will prove sufficient to contain the impact. In Campania, President Vincenzo De Luca has set up a plan to recover 490 beds, 102 of which are for intensive care. The more severe scenario, as he explained in one of his direct broadcasts, involves using «150 seats». We said, "we have to hold a month and a half, In Puglia, President Michele Emiliano must review the initial plans, he explains in an interview with Repubblica, in the light of the return "unexpected from the North" of almost 18,000 people, important and above all "underestimated" numbers because not all of them declared themselves. And then the Region, relying on the epidemiologist Pierluigi Lopalco, organizes itself to contain the infection by trying to "avoid hospitalization". In any case, the strategy throughout Italy will have to be mixed. Quarantine, yes. But also the search for the infected. In this sense - the team of doctors from Wuhan who came to Italy also said - the examination of the swab is done too little. We need a blanket approach, not limited only to those who have symptoms, since the infection often also passes through the asymptomatic. The model indicated would be South Korea. And if a new test model arrives shortly which allows results in a few minutes (and not the 24 hours needed now) this type of operation will become possible.

PoliGraph 今天 07:29 来自 iPhone客户端 已编辑 *关爱意大利**意式封城效果有多显著?**自由浪漫的意大利人民会乖乖呆在家嘛?**图好看* 意大利疫情的严重和措施的强硬震惊了整个西方世界。这一篇文章具体何衡量了【封城】是否有助于【降低人员流动】和【减少人际接触】。意大利ISI基金会和Cuebiq智能分析公司联合Turin大学进行了一项研究,对于空间流行性的相关指标进行了大规模的量化。先来复盘一下意大利到目前为止的【疫情大事件】: 【意大利的主要时间线】 1月31日:一对来自武汉的夫妻被确诊。这是意大利首次确诊新冠病例。 2月6日:一名从武汉回国的意大利人被确诊,确诊病例上升到3个。 2月18日:第4名感染者在北部Lodi省的Codogno地区被确诊。这被认为是意大利的第一例本地传播。 2月23日:确诊人数达到150人。当天,意大利对北部的伦巴第和威尼托的11个市镇实施隔离封锁。 2月25日: 确诊人数达到320人。意大利北部6个大区的学校停学。全国生病超过5天的学生不得入校。 3月8日: 确诊人数达到7375人。意大利封锁伦巴第大区以及其他14个省,其中包括旅游城市米兰和威尼斯。 3月9日: 确诊人数达到9172人。意大利宣布全国封城。 3月12日:确诊人数达到15113人。意大利宣布关闭全国所有商店和餐馆。 3月16日:确诊人数达到27980人。意大利预计在【3月18日】达到感染人数的峰值,最终4月底疫情结束。 这项研究通过对【17万】用户手机的定位跟踪(精度达到10米级别),以【5分钟】作为采样频率,收集了从2月22日(意大利北部封城前一天)到3月10日(意大利封国的第二天)之间一共【1亿7千5百万】匿名的位置数据。 以周(7天)为单位,以下三个星期分别代表了意大利在此次抗疫的三个阶段: • 第一周(2/22-2/28):最先出状况的北部11个市镇开始进行隔离。 • 第二周(2/29-3/6):出行的限制逐步推广到整个意大利北部。 • 第三周(3/7-3/10):意大利全国封锁。 【省际人员流动】 【图1】【图2】【图3】三张图分别展示了三周内每个省用户出省率的变化。第一周,流动的下降在伦巴第的克雷莫纳地区(小提琴的发源地)最为显著(30%),意大利整个北部地区也有都有不同程度的影响。第二周,整个伦比第和艾米利亚-罗马涅大区都下降了30%,对于其他北部地区的影响也加深了。第三周,全国非常听话地都下降了50%。 【人网连接度】 因为采用的是手机定位数据,不能直接测量人与人的接触次数。文章里特别用了一个【网络】概念。如果任意【两个或以上的用户之间的距离在50米之内超过一个小时】,那一个网络就形成了。每个人在网络里都是一个节点,可以和50米以内的其他用户形成一个连线。最后按照网络连线和网络节点的比值来计算网络的连接度。连接度越大,说明人与人的接触次数越多。文章中比较了第三周和疫情爆发前意大利各省的连接度。如【图4】所示,整个意大利都有显著的降低(灰色的省份是由于用户太少,产生的网络不稳定,就不用了)。在深蓝色的区域,平均的网络连接度与疫情前相比下降了30%。总体来看,颜色还是层次不齐,看来【每个省的执行力度还是很有区别的】。 【个人移动距离】 在疫情爆发前,有一半的人口每周出行的距离超过【5.7公里】。但是在第三周,一半的人口只有不到【2公里】的距离。按照人均来算,移动的距离从第一周的13公里下降到第三周的7公里。 翻译/主编:@诗书易春秋 Source: O网页链接收起全文 https://covid19mm.github.io/in-progress/2020/03/13/first-report-assessment.html?nsukey=DvzkSdjGKpNAKcA4QP3a7TqupJgB2vphoenHedYLKg3PbCl0rE%2Bsbcl5UKlxxdz9coPEe0LU3Qr%2BOQw0%2BtM%2FVmTKFZi2i3JA2mooEmssii3V2owRW%2FOpvtoELp9ox%2Bko9jkvQMerMrA87TbDVxLyfXsR%2BGnRWzGNdkZcrVC%2B%2FAUlc4Q0K9m4JcO4P8sfxmVG%2B82iYVCQKVKd%2B%2FPotY10vQ%3D%3D
