I am wondering if all these cases emerged because of the large scale investigation going on. Is it possible that the coronavirus is more spread than expected, but there are more asymptomatic cases than what we think? Are other countries doing the same? It is quite strange that everything started all together from different part of the country and they didn't find the patient zero.

It's always more spread than expected because the symptoms of infected people take time to appear and temperature screening is almost useless. An actually effective way pandemics can be stopped for sure requires an international effort and discipline... quarantined people must stay isolated from others and prevented from entering any country until the maximum incubation time. It sucks for commerce and tourism, but that's just too bad. It's a fail of reckless, spineless officials who enable infected idiots to turn an isolated disease into a worldwide pandemic.

Which is exactly why coutries with heavy tourism, such as Thailand aren't reporting the real number of cases they have (my personal assumption).

How would this be possible with asymptomatic and subclinical spread? With the absence/unreliability of testing you'd damn near need to quarantine anyone with mild cold/flu symptoms.

Even China now appears to be relaxing their quarantines because of concerns about the economic impact.

I think we're just going to be dealing with this over the next 12-18 months, as countries see it arrive and spread within their borders.

Given month of incubation time (from when you catch it, and are asymptomatic, but still spread it), it's not unreasonable to assume for sake of alternate models it's been spreading since November and people just thought of it as case of particularly bad cold. Only know of it since it got too big to hide by Chinese govt.
