There has been some discussion recently about the concept of reaching so-called “herd immunity” by letting the virus spread, herd immunity is a concept used for vaccination in which a population can be protected from a certain virus, if a threshold of vaccination is reached.
最近有一些讨论,建议通过使病毒传播来达到所谓“群体免疫”的效果。群体免疫是用在疫苗接种方面的概念,如果达到疫苗接种的阈值,则可以保护人群免受某种病毒的侵害。
For example, herd immunity against measles requires about 95% of a population to be vaccinated. The remaining 5% will be protected by the fact that measles will not spread among those who are vaccinated.
例如,对麻疹的群体免疫要求大约95%的人口要接种疫苗,剩余的5%将因为麻疹不再传播而得到保护。
In other words, herd immunity is achieved by protecting people from a virus not by exposing them to it. Allowing a dangerous virus that we don't fully understand to run free is simply unethical. It's not an option.
换句话说,群体免疫是通过保护人们免受病毒侵袭而实现的,而不是使他们接触病毒。允许一个尚不了解的危险病毒自由传播是不道德的。 这不是一个选择。
But we do have many options. WHO recommends case finding, isolation, testing, compassionate care, contact tracing, quarantine, physical distancing, hand hygiene, masks, respiratory etiquette, ventilation, avoiding crowds and more. This is what countries are proving works every day.
但我们确实有很多其他选择。世卫组织建议包括及早发现病例,采取隔离措施,做病毒检测,精心护理,跟踪密切接触者,做好隔离检疫,保持社交距离,注意手部卫生,佩戴口罩,注意呼吸礼仪,勤通风,避免人群聚集等等,这些是各国每天都证明行之有效的方法。 |
