I'm really scared about ebola, how is it transmitted ? and should people in the u.s be scared?

America is a great: place to be at this time. There has been 1 case diagnosed in the US. The CDC & local/state medical authorities have closely monitored /contained contacts of Patient zero. We are blessed to have a well established medical infrastructure in the US - unlike some of the West African countries that are hardest hit at this time. Transmission is from someone who has signs of active infection via contact

Avoid contact: Ebola is spread by direct contact with an infected person or the remains of a person dead of the disease. So stay away from West Africa and also be conscious of any cases in the rest of the world. US Public Health authorities are working hard to limit any spread and I believe will be successful. This is something to be intelligent about and not to be scared.
