It may be true in the ancient time. But not true in the global village age.
Virus spread speed is in a way of acceleration. Massive infections normally don't happen at the early stage. If the origin of the virus happens to be a low population density place, the early stage could be a very long period. In this window time, if the virus was brought to another country's high population density place(big city for example), the virus outbreak speed in this country could be even faster than the origin country.
Considering the symptoms of the Covid-19 are pretty much like flu, and some cases have no symptoms at all, the possiblily of transnational spread before people even knew this virus exsits is very big.
