New Jersey Governor Chris Christie and New York Governor Andrew Cuomo announced Friday at a joint press conference that any healthcare workers returning from treating Ebola patients in West Africa will be placed in mandatory quarantine. This statement comes a day after a Médecins Sans Frontières physician tested positive for the virus upon returning to New York City earlier this month. 

Gov. Cuomo insisted that he will continue to "[err] on the side of caution when it comes to the safety and protection of New Yorkers." 

State health department staff will be present at New York's JFK Airport and Newark Liberty Airport in New Jersey to implement the quarantine, as well as to assess whether other travelers should be hospitalized or quarantined. 

A host of questions remain as to how exactly the screening will be executed, as well as what specific guidelines the health department will use to discretionarily quarantine the common travelers.
