The expense of saliva collection devices designed to stabilize severe acute respiratory syndrome coronavirus 2 RNA is prohibitive to mass testing. However, virus RNA in nonsupplemented saliva is stable for extended periods and at elevated temperatures. Simple plastic tubes for saliva collection will make large-scale testing and continued surveillance easier.
用于稳定严重急性呼吸综合征冠状病毒 2 型 RNA 的唾液采集设备费用昂贵，不适合大规模检测。然而，未添加任何物质的唾液中的病毒 RNA 可在较长时间内保持稳定，即使在高温下也是如此。简单的塑料唾液采集管将使大规模检测和持续监测变得更加容易。
