NEW YORK (AP) – The federal program that requires weeks of monitoring for travelers from African countries with Ebola is turning a month old. And so far, no cases of the disease have turned up.

The program tracks people for 21 days if they’ve arrived from Guinea, Liberia, Sierra Leone or Mali. The idea is to see whether symptoms of the disease appear. Each state chooses its own method of monitoring. Most tracking is done through daily phone calls.

More than 2,600 people have been tracked under the program, which reaches the one-month mark on Thursday.
