From NHK TV in Japan to the city of Chickasha, Oklahoma, we welcome our viewers from all over the world.First up on commercial free CNN STUDENT NEWS we are taking you to Africa.The Ebola outbreak we've been following this year has mostly been limited to West Africa.But new cases of the hemorrhagic fever are turning up in the Democratic Republic of Congo, in Central Africa.It appears to be a different strain of the virus, meaning it's a separate one from the outbreak that's killed 1500 people in West Africa.But doctors are scrambling to contain it, because Congo borders nine other countries, and an outbreak there could be catastrophic.There's no cure. Ebola kills many of those who get it.Though people can survive, if they are treated quickly with fluids, medicines and nutrients.One big question, though, how do you stop it?Ebola outbreak in Africa has left hundreds dead and many more infected. To halt even more infections, finding and treating all the patients is key.But just as important as finding and monitoring all the people who had close contact with those patients.These people, they may have slept in the same house, they may have come in contact with the patients' body fluids.And not all of the patients' close contacts are going to get sick. But those who do can then expose even more people to Ebola. It's called a chain of transmission.I want to give you a real world example from an Ebola outbreak in the early 2000s.A young woman from Uganda didn't know she was sick with Ebola. She had closed contacts with six people.Her baby and father in law, they both got sick. The baby then got his grandmother sick and she had contact with two more people as well.
