In the coming days, states including Virginia and California will likely have the opportunity to decide if they want to take steps to curb their spread.
The virus has hit the American Southwest, a region of more than 40 million people, and has affected at least 30 people in California and Texas.
In the coming weeks, many counties in those states are expected to hold public hearings, and public health officials have already warned residents to keep their windows shut.
A handful of counties, including San Antonio, Houston and Dallas, will also be holding public hearings to assess how they will respond to the virus.
Even though California has declared a state of emergency, it has not yet announced its plans for what it will do in the wake of the virus’s arrival.
On Monday, California Gov.
Jerry Brown issued a proclamation allowing local governments to declare emergency conditions in a “precautionary measure” to help reduce the spread of the coronavirus.
However, the state is not allowing counties to impose mandatory measures like a curfew, and will not enforce those measures.
Officials say the declaration of a state-wide emergency does not require counties to restrict travel, and does not authorize local authorities to impose emergency conditions on public buildings.
Officials say counties are still considering whether to implement restrictions on the use of cellphones and to restrict the movement of people.
