Dr. David Lakey, the Texas health commissioner, was asked whether Duncan would have benefited from earlier treatment with the drug.

"I just can't answer whether or not that would have helped him. We just don't know with these experimental drugs, how well they work."

Lakey spoke about the people whoare being monitored because of their contact with Duncan.

"There are 48 individuals that we are watching closely," saidLakey. "All these individuals are being checked for fever twice a day. There are no sightings of fever or illness so far."

He cautioned that this was a "crucial week" for people who have had direct contact with Duncan. Symptoms of Ebola tend to show upeight to 10 days after being in contact with an infected person.

Dallas officials also said they have been in touch with community groups and churches in the area where Duncanhad been staying and co-ordinating an information campaign in several languages.

Duncan became ill after arriving in Texas from Liberia two weeks ago, heightening concerns that the worst Ebola epidemic on record could spread from West Africa, where it began in March.

Dallas officials on Monday alsoannounced that all of Duncan's possessions had been destroyed and many materials from the apartment have been put into "containment barrels."

It has killedmore than 3,400 people since it began in West Africa in Decemberand has now begun spreading faster, infecting almost 7,500 people so far.
