COVID-19 testing is not done like other types of testing, including influenza, so it isn't as simple as just screening everyone a doctor chooses to. That just is not an option.
CDC guidance is still based on travel to china or close contact to known case:

https://www.cdc.gov/coronavirus/2019-nCoV/hcp/clinical-criteria.html
But see also

- For patients that are severely ill, evaluation for COVID-19 may be considered even if a known source of exposure has not been identified.

Healthcare providers should
immediately notify both infection control personnel at their healthcare facility and their local or state health department in the event of a PUI for 2019-nCoV. State health departments that have identified a PUI should immediately contact CDC’s Emergency Operations Center (EOC) at 770-488-7100 and complete a 2019-nCoV PUI case investigation form available below.
CDC’s EOC will assist local/state health departments to collect, store, and ship specimens appropriately to CDC, including during afterhours or on weekends/holidays. At this time, diagnostic testing for 2019-nCoV can be conducted only at CDC.
Testing for other respiratory pathogens should not delay specimen shipping to CDC. If a PUI tests positive for another respiratory pathogen, after clinical evaluation and consultation with public health authorities, they may no longer be considered a PUI. This may evolve as more information becomes available on possible 2019-nCoV co-infections.
