多于 5.5 美国有百万人已经感染了新的冠状病毒, 许多研究机构依次开发了不同的检测方法. 耶鲁大学公共卫生学院开发了一种新的唾液测试方法，不仅在几个小时内获得结果, 但每次也只花费大约十美元. 美国. Food and Drug Administration has issued an emergency authorization permit, which is the fifth saliva test approved.

The US media reported that this type of saliva test is quick and cheap because it omits the step of isolating the ribonucleic acid (核糖核酸) from the virus. It only needs to add reagents to the sample and release the virus genome through a short heating process.
