7/31 继续戴口罩
魏薇 (2021-07-31 07:40:55) 评论 (0)昨天从广播里听到了对FAUCI的采访。由于DELTA变种病毒,CDC修正了COVID-19的关于口罩令的指导意见:建议即使是接种完疫苗的人群,在室内时仍然需要戴口罩。因为他们可能被病毒传染,也可能传播病毒,这与之前的说法不同。我想这一新决定的产生,是由于过去一个月来,在美国各地发生的染疫人数增加都有所增加。染疫的案例很多,其中最受人关注的是发生在麻州,因为群聚而引起的感染事件。看了下,染疫的导火线是七月四日的几场酒吧庆祝活动。总计60,000多人的聚会者中有600多人被查出被感染,其中74%的感染者是接种过疫苗者。而这600多人中,有五个住院者。这五个住院者中,没有一个是重症。这五人中,一个接种的是Pfizer疫苗,四人接种的是J&J疫苗。
这样看来,打了疫苗感染机率在1%左右,好在感染也不是重症。还在纠结要不要给儿子打疫苗,再接着想想。过去一年多,在没接种疫苗前,我一直在上班,采取的措施是室内戴口罩。儿子和我一样,一直去学校上学,一直保持室内戴口罩。在室内,戴口罩还是最简单的方法。

Given the increasing Covid-19 infection rate all of the country and CDC 's new restriction guideline on mask-wearing, Dr. Fauci was invited to an interview in NPR to answer some quesitons people eager to know the answers from a notable viral expert.
Dr. Fauci said we are facing a differnent enemy---Delta virus, which is more transmissible, contagious, and having a lot things unknown. The strong transmission of Delta virus is comparable to the infamous chicken pox virus. when being asked what's the point of getting vaccination since people still may have chances of infection. Dr. Fauci said " Yes, there are still chances of getting infection, but the syptoms will be much milder, it will not be as severe as the people who are not being vaccinated.
After further research, I found the infection rate of Delta virus for fully vaccined people is sightly above 1%, not quite bad. The rate is caculated from the most striking gethering events happened in Massachusetts on July 4th celebration. In a few indoor getherings involving more than 60k people, over 600 people were tested COVID-19 positive. of all the 600+ people, 74% are fully vaccined people, which sounded very scary! Of all the 600 plus infected people, 5 people were hospitalized. And among them, none was in server situation. Surprisely they even exposed the vaccines the 5 people got. one got Pfizer, four got J&J. Then onbody want J&J, I guess.
