Can you verify that, to date medical authorities are yet to locate either the initial reservour of the virus and also any responsible vector for it?
No vector yet, but they say it resembles a bat version of coronavirus, but it may be carried by camels or goats.

are of the opinion that this bug will get going and end up being another pandemic killer.
I think it has a distinct possibility of doing just that, and so do many scientist and researchers. Too much is unknown about it, and speaking of unknowns... all the gov'ts concerned are hiding up to date and critical information. Dude was dead for 2 weeks before they eve tell you about it. The death in the UK was taking cancer therapy.

They keep saying no problem and no widespread continuous h2h, but they are all getting ready and making plans for it. So with that in mind, err on the side of caution, just like they are.

The stuff is just too new to make a snap judgement on it like if it was a flu type infection. It has shown a tendency to go h2h in family and close settings, it is dangerous, and they are hiding info. They don't want to cause panic, but ALL gov'ts are watching close and some are implementing stricter border rules. They aren't doing it for nothing. I am not in panic mode, but it is a challenge to squeeze out the latest tidbit of info. A new report says there is no 4th case in England, but when you read the report, it says they aren;t looking for it in that particular instance anymore. The person was sick but never tested, so another mild case in my opinion. Subject: Correction to ProMED-mail statement [in Novel coronavirus - East. Med.
