Gov. Andrew Cuomo has laid out more detailed guidelines for the 21-day quarantine ordered for health care workers returning from West Africa. 

Cuomo and New Jersey Gov. Chris Christie had announced the quarantine on Friday, ordering returning medical workers to be quarantined and isolated, but it wasn't clear exactly what that meant. 

The governor is now clarifying the protocol, saying that a person who shows symptoms of Ebola will be transported by medical vehicles in protective gear directly to an isolation unit in a hospital designated to treat the virus.

If a person doesn't have symptoms, but was in direct contact with sick patients, then they will be taken by private vehicle directly to their homes where they will be quarantined for 21 days, which is the time it takes to see if Ebola has been contracted. Those people will be checked on by health officials twice a day, their family will be able to stay with them and some may receive visits from friends. 

Finally, if someone returns from an affected Ebola area, has no symptoms and had no direct contact with an infected person, then they will be monitored for 21 days, but will not be subject to quarantine. 

Cuomo says that the government will cover food and medical costs, and may provide financial assistance to those who are in quarantine. 

Screening is initiated by customs and border patrol officers at the airport. Additional screening will also be conducted by the state's Department of Health, as well as the city's.
