Like, the weather will make it go away.. just like seasonal flu. 

These are assumptions and hopes. I prefer real data and science to back my beliefs. And currently there is no data stating that the carriers NEVER get symptoms. They get mild symptoms. In the Iceland study, they never went back and asked the asymptomatic positives if they later got symptoms... so how can you rely on that data? The Chinese state that from incubation to symptoms is 1-14 days with 5 the average. (one outlier at 27 days)...
