Coronavirus STORY (Serum Testing of Representative Youngsters)

追踪新型冠状病毒等新型病毒传播的一种重要方式（COVID-19）是研究普通人群对该病毒的血液免疫力。在爆发之初测量这一点可以确定多大比例的人口（如果有的话）已经具有免疫力，持续监测这一比例的任何增加都可以显示有多少人正在获得新的感染。这对儿童尤其重要，他们通常是将呼吸道感染传播给他人的罪魁祸首。因此，英格兰公共卫生部计划在COVID-19爆发期间每月研究400名儿童和青少年的COVID-19抗体浓度（免疫力标志）。

An important way of tracking the spread of a new viruses like the novel coronavirus(COVID-19) is to study the blood-born immunity against that virus in the generalpopulation.Measuring this at the beginning of an outbreak can determine what proportion (if any) ofthe population already have immunity, and ongoing monitoring for any increase in thisproportion can show how many people are getting new infections.This is especially important for children, who are often responsible for spreadingrespiratory infections to others.Accordingly, Public Health England plan to study the concentrations of antibodies (amarker of immunity) against COVID-19 in 400 children and teenagers per month for theduration of the COVID-19 outbreak.
