President Obama urged Americans not to get hysterical about Ebola, at the same time asking citizens, government leaders and the media to contribute in the fight against the disease.

"This is a serious disease, but we can't give in to hysteria or fear-because that only makes it harder to get people the accurate information they need."  "We have to be guided by the science," Obama said, Saturday, reports the Associated Press.

In his weekly radio and Internet address, Obama also opposed the calls by U.S. lawmakers for imposing a travel ban from the Ebola stricken West African countries.

Obama said that hindering travel would only allow the outbreak to spread as travelers would seek ways to evade the official restrictions.

"Trying to seal off an entire region of the world - if that were even possible - could actually make the situation worse," Obama said.

Expressing confidence that the United States could prevent a serious outbreak at home, Obama said that the fight against Ebola will take time.

Elaborating further, Obama said that Centers for Disease Control and Prevention had deployed staff to the Texas Presbyterian hospital in Dallas, where the infected nurses' worked. The CDC has also sent staff to Cleveland, where one of the nurses traveled before she became infected with the virus, he said, reports Bloomberg.

Meanwhile, a White house statement Friday said that Obama intends to assign senior personnel to work on the ground in Dallas to ensure the requirements of the region are met.

An experienced FEMA coordinator and a White House liaison will also join in the effort, the statement said.

In the wake of criticism over the administration's efforts in containing the disease at home, Obama appointed former White House adviser Ron Klain as the United States Czar  Friday to oversee the Anti- Ebola operations.
