一般来说，无症状传染的几率不大， 因为感染性和病毒体内载量直接相关. 也就是说, the viral load is not enough to reach an infectious dose. 调节好自身状况，多休息多饮水，你身体健康没有underlying diseases, 就算中招也就如同感冒，别自己吓自己。(就目前Omicron来看，COVID-19 will join the 4 other coronaviruses we deal with that cause the common cold, upper respiratory infections, RSV, etc. It will become a pediatric disease mainly affecting young children with no immunity).
The viral load is a measure of how bright the fire is burning in an individual, whereas the infectious dose is the spark that gets that fire going.
