Dr. Sanjay Gupta on the ground in an ebola outbreak

More than 100 people have died in Guinea's ebola outbreak, that includes 14 health workers. The virus has no cure and you can get infected with just one microscopic droplet of saliva or blood hitting a break in the skin. The outbreak struck Guinea's capital Conakry, a city that's home to two-million people and near an international airport. Dr. Sanjay Gupta is there with the latest on the crisis and shows how simply getting blood samples is a life threatening job.
