One concern of mine is the way some of the Dr's have been speaking about transmitting the virus. Most of the ones I have heard have spoken in absolutes, saying that the virus cannot be spread until the infected person shows symptoms. From what I have learned about biology, is that virus' act different within different individuals, and that virus' evolve. So, to speak in absolutes, saying that there is absolutely no way this can spread until the infected person shows symptoms, just seems a bit arrogant. Also, what is classified as a 'symptom?' Would general malaise or fatigue be considered a symptom? Because those aren't visible typically.
