US President Barack Obama today urged the Americans not to get too panicky over Ebola and asserted that it is not advisable to move ahead with the idea of travel bans from Ebola-ravaged countries in West Africa, claiming that the travel ban could make things worse.

Earlier this week, American lawmakers had urged Obama to bar people from Liberia, Sierra Leone and Guinea from entering the United States. The US president noted that he is not against the idea of travel bans, but in his weekly address the US leader clarified that at present he is no mood to go with a travel ban.

"We can't just cut ourselves off from West Africa," Obama said, adding that the bans could create trouble for health workers to move into the affected region and it would also affect the supplies of medical aid into the region. He said that the travel ban would motivate people trying to get out the region to evade screening and it would create problem in tracking the Ebola cases.

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

Obama said it would take time to fight the disease, warning "before this is over, we may see more isolated cases here in America."

In an apparent effort to put the disease in perspective, reminding Americans that so far only three cases have been diagnosed in the country and this deadly viral disease is not contracted easily.

"What we're seeing now is not an 'outbreak' or an 'epidemic' of Ebola in America," he said. "This is a serious disease, but we can't given in to hysteria or fear."
