“...that it expects community transmission...”
Definition: transmission from person to person but persons transmitting it are unidentified. It is not magic or anything uncommon, just that the carrier has not been identified. The media and deep state CDC and other doctors are using the term “community transmission” to induce fear and confusion.
The CDC and all the other government agencies use the term community transmission because that is the defined medical term for what is taking place in parts of Washington state, Oregon and California it is not a grand conspiracy it is the expected and required terminology for the events that are taking place.
The significance of community transmission is that it confirms the presence of individuals in a community spreading infection that are not known cases. This by definition means containment has been lost and unrestricted movement of infectious persons is occurring. Like it or not this bug is out in the general population now and that marks a change in the strategy to contain it to a limited geospatial area, and most importantly to break the chains of infection to bring the R0 to under 1. Only when the R0 is under one can the virus burn itself out any number higher than one and the cases will increase currently the R0 is unknown in the USA the CDC has only done less than 500 tests, but world wide it has been from 2 to 6 A for reference influenza A typically has an R0 of 1.2_1.6
