2021年4月18日全球新冠肺炎(COVID-19)疫情简报,确诊超1亿4129万,疫情反弹至前次高点,中国免疫屏障建立仍然需要较长时间

2021-04-18 MedSci整理 MedSci整理

Worldometers世界实时统计数据显示,截至北京时间2021年4月18日7时01分,全球累计确诊新冠肺炎(COVID-19)病例超过14129万例,新增780,041例,达到141,291,06

Worldometers世界实时统计数据显示,截至北京时间2021年4月18日7时01分,全球累计确诊新冠肺炎COVID-19)病例超过14129万例,新增780,041例,达到141,291,061例。累计死亡病例超302.3万例,达到3,023,064例,新增死亡为11,509例。康复为119,903,274例,重症和危重症病人达到106,777例;全球新冠确诊病例超过100万例的国家达24个,88个国家病例超10万例。美国新冠肺炎累计确诊病例全球最多,超过3237万例,达到32,371,423例,新增62,885例;累计死亡病例达到580,631例,新增死亡710例。印度新增260,778例,连续多日创新高,印度病例位居全球第二。巴西疫情昨日新增65,792例,死亡2865例,昨日报道:2021年4月17日全球新冠肺炎(COVID-19)疫情简报,确诊超1亿4049万,美国超1.25亿人接种过疫苗

梅斯医学观察到,当前疫情再次回到前次高点,而且增长迅速,从势头来看,疫情还会持续上升。虽然,随着全球疫苗的使用,仍然未能扼制疫情的发展。虽然日死亡人数仍然没有达到此前水平,但是随着印度疫情的发展,死亡率接下来会快速上升,死亡人数增加很难避免。

从美国来看,美国整体死亡率为1.8%,当前的疫情的死亡率在1.1%左右,仍然未下降至1%以内。而巴西的死亡率由3%增加至4%,可能与突变病毒相关;印度前期死亡率较低,一直维持在1.1%左右,此次突变病毒会不会增加死亡率,还需要一段时间观察。整体而言,全球形势不容乐观。

美国目前接种剂次超过2亿剂次,中国为1.8亿剂次,中美两国日接种剂次美国在300万剂,中国约在400万剂。但是中国是人口大国,若以此接种速度,中国实现全民免疫需要到明年以后。因为中国实现接种需要10亿人,约20亿剂次才有可能实现全民免疫。

美国至少21个州报告新增确诊病例每日增幅达10%以上

根据美国约翰·霍普金斯大学(Johns Hopkins University)最新数据,美国至少有21个州报告每日平均新增新冠肺炎确诊病例增幅达10%以上,各州医疗系统压力日渐增加。美国疾病控制与预防中心(CDC)主任罗谢尔·瓦伦斯基在当地时间4月16日的白宫新冠疫情简报会上表示,美国过去7天平均新增病例增长至约6.9万例,过去7天平均急诊率、入院人数和住院人数均上升5%~8%,日均死亡人数已连续第三日增长至超过700人。

美国FDA撤销礼来新冠抗体药品的紧急使用授权

当地时间周五,美国食品药品管理局(FDA)撤销了礼来新冠抗体药物bamlanivimab的紧急使用授权。FDA在声明中解释称,因为对bamlanivimab有抗药性的变异病毒增加,仅仅使用该药物治疗新冠肺炎感染者“治疗失败的风险越来越高”,使用该药物的益处已不再超过风险,已经不符合紧急使用授权条件。

WHO:全球新冠感染率逼近疫情爆发以来最高水平

当地时间周五,WHO总干事谭德塞在新冠肺炎例行发布会上表示,世界各地病例数和死亡数继续以令人担忧的速度增长。过去两个月,全球新冠肺炎的每周新增病例翻了将近一倍,正逼近疫情爆发以来最高感染率。

中国已接种新冠疫苗18736.8万剂次,建免疫屏障或需10亿人打疫苗

据国家卫健委数据,截至2021年4月15日,31个省(自治区、直辖市)和新疆生产建设兵团累计报告接种新冠病毒疫苗18353.6万剂次。

王华庆还表示,我们国家要建立免疫屏障,可能需要10亿人以上接种新冠疫苗,接种率越高,免疫屏障形成就越牢固,接下来我们还有一段路要走。

美国疫苗接种超过2亿剂次
