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

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 says 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 and 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. Gov. Cuomo said they are subject to "legal action" if they don't stay at home. 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.

The CDC recommends only voluntary at-home quarantine for travelers from West Africa, even those who were in contact with Ebola patients.

Meanwhile, a little boy from the Bronx tested negative for Ebola Monday night.

The 5-year-old boy was taken to Bellevue Hospital Sunday night when he started showing symptoms of the virus.

The boy had been vomiting and had a 103-degree fever after returning home from Guinea over the weekend.

Further negative Ebola tests are required on subsequent days to ensure that the patient is cleared. The patient will remain in isolation until all test results have returned.
