Ebola: Obama 'optimistic' on virus situation in US
President Barack Obama has expressed cautious optimism about the Ebola situation in the US, as new screening rules were introduced in the country, the BBC reported.
He said many relatives of the only known person to have died of the virus in America seemed to be out of danger.
Mr Obama said there were "modest signs" of progress in Liberia - the hardest-hit nation in West Africa.
The known death toll is now 4,877 - a rise of 322 since last week's report by the World Health Organization.
Most of the victims died in three West African nations - Liberia, Guinea and Sierra Leone.
President Obama's comments came on Wednesday after his meeting with the head of America's newly formed Ebola response team, Ron Klain.
Mr Obama noted that relatives of Thomas Eric Duncan - the only virus victims in the US - had now been freed from quarantine in Texas.
He also said two nurses infected as a result of treating Mr Duncan "seem to be doing better."
