CDC修改防疫指南 取消追踪确诊接触史
摘要: 新冠疫情爆发至今两年，随着全国确诊数、住院率和死亡率下滑，联邦疾病防治中心(CDC)已宣布修改防疫指南，取消建议为确诊个案进行接触史追踪，并聚焦于高感染风险的环境；这也反映，欧洲国家及国内超过一半以上的州 ...
 专门追踪确诊者接触史的约翰霍普金斯大学(JHU)健康安全中心资深学者克里斯托‧华森(Crystal Watson)表示：「这是个很大的改变，也反映各州和地方政府的现况，尤其是变种病毒Omicron爆发后，根本没有办法可以追上传染的速度，加上很多确诊案例没有通报，我们根本无从查起。」 依照最原始的接触史追踪计划，只要与国内确诊者在六呎以内的距离交互超过15分钟的人，无论病毒筛检结果为合，即被匡列并要求居家隔离两周；不过碍于各单位搜集的参数不齐、确诊量不一、检测结果延后等因素，造成病毒流行率难以掌握，接触史追踪的难度增加。 如今CDC向公卫部门强调聚焦在单一高风险环境，如长照中心、监狱、拘留所或庇护中心；另外，随着疫情趋缓，防疫措施放宽，免疫功能不足的患者风险也跟着增加。 CDC发言人诺德隆德(Kristen Nordlund)表示：「更新防疫指南是为了因应疫情的变化，以及抗疫工具和资源的取得性已变得更加容易。」 不过华森也坦言，新的防疫指南恐怕让好不容易创建的接触史追踪系统瓦解；2020年冬天疫情巅峰之际，国内负责接触史追踪的人员多达7万人，华森说：「我们应该将重建公卫系统的资源，取一部份做更广泛的应用，让我们在下一波危机来临时，可以紧急找来足够的人做接触史追踪。」 |

- Cool website!
My name_s Eric, and I just found your site - dahuafu.us - while surfing the net. You showed up at the top of the search results, so I checked you out. Looks like what you_re doing is pretty cool.
But if you don_t mind me asking _ after someone like me stumbles across dahuafu.us, what usually happens?
Is your site generating leads for your business?
I_m guessing some, but I also bet you_d like more_ studies show that 7 out 10 who land on a site wind up leaving without a trace.
Not good.
Here_s a thought _ what if there was an easy way for every visitor to _raise their hand_ to get a phone call from you INSTANTLY_ the second they hit your site and said, _call me now._
You can _

- My name_s Eric and I just came across your website - dahuafu.us - in the search results.
Here_s what that means to me_
Your SEO_s working.
You_re getting eyeballs _ mine at least.
Your content_s pretty good, wouldn_t change a thing.
BUT_
Eyeballs don_t pay the bills.
CUSTOMERS do.
And studies show that 7 out of 10 visitors to a site like dahuafu.us will drop by, take a gander, and then head for the hills without doing anything else.
It_s like they never were even there.
You can fix this.
You can make it super-simple for them to raise their hand, say, _okay, let_s talk_ without requiring them to even pull their cell phone from their pocket_ thanks to Talk With Web Visitor.

- Hey there, I just found your site, quick question_
My name_s Eric, I found dahuafu.us after doing a quick search _ you showed up near the top of the rankings, so whatever you_re doing for SEO, looks like it_s working well.
So here_s my question _ what happens AFTER someone lands on your site? Anything?
Research tells us at least 70% of the people who find your site, after a quick once-over, they disappear_ forever.
That means that all the work and effort you put into getting them to show up, goes down the tubes.
Why would you want all that good work _ and the great site you_ve built _ go to waste?
Because the odds are they_ll just skip over calling or even grabbing their phone, leaving you high and dry.
But here_s a thought_ what if you could make it super-simple for someone to raise their hand, say, _okay, let_s talk_ without requiring them to even pull their cell phone from their pocket?
You can _ thanks to revolutionary new software that can literally make ...
