Henry,

Thanks for the information you provide this thread and the time you spend posting here. I have a question about your comments"

The SARS CoVs are easily transmitted by patients with "summer cold" symptoms.

Seasonal cofactors may be required for the SARS presentation seen last winter and spring.



So what you are saying is that the SARS CoV is being spread unbeknownst to us during this summer season, and when winter arrives it will resurface in its deadly form? Correct?

Are there other examples of viruses that do this, i.e. spread in a mild form and then turn deadly later?

Do any other coronaviruses exhibit this behaviour?

What are the cofactors that cause this change from mild to deadly?

I am not a scientist, only an investor trying to weigh the risks of a SARS outbreak this winter and the information that has been posted on this forum about seasonality seems to suggest that most viruses "disappear" during their "offseasons" not that they change their potencies. What am I missing? Thanks.
