CARL AZUZ, CNN ANCHOR: FAFSA sounds kind of like a soft drink, but it`s more relevant to financial literacy and it`s coming up later today on CNN STUDENT NEWS. I`m Carl Azuz. Welcome to the show.

First up today, a tribute. Yesterday was the first anniversary of the terrorist attacks in the Boston Marathon. Three people died in the bombings, scores were injured, police say an officer was killed later by the bombing suspects. But the city soldiers on. From a moment of silence at the races finish line to sound of church bells ringing and the raising of the American flag. The ceremony embodied the slogan Boston Strong. Thousands of people gathered in the rain, from first responders and the vice president to runners and injured victims. One man who had shrapnel in his leg said that last year he was on the ground at the finish line, this year he`ll be running across it.

Is this legit? There`s a vaccine for the Ebola virus? Not legit. There is no known cure or vaccine for Ebola. Avoiding close contact with Ebola patients is crucial.

One unique thing about Ebola is that unlike some other viruses, people don`t tend to spread it, until they actually get sick with it. So, it`s only when they are feverish that they are contagious. Once they are, it spreads very easily and kills more than half of those who get it. It`s never infected humans in the U.S., but for scientists researching and trying to stop Ebola`s spread in Guinea, taking extreme precautions is just part of the job.

SANJAY GUPTA, CNN CORRESPONDENT: A simple blue box, potentially carrying one of the most dangerous pathogens in the world on its way to be tested. In less than four hours we`ll find out whether it contains the Ebola virus. The fate of three patients depends on what`s inside. Simply getting the blood samples is a life threatening job. One of these workers told us, he has a nine-month old baby at home. They`ll do everything they can to protect themselves. Three pairs of gloves, booties and layer after layer of gowns. They go in to see the patients. Every single inch of their body covered. Impermeable suits, nothing in, nothing out. You see, even a drop of the Ebola virus that gets through a break in your skin can infect you. And we all have breaks in our skin.

This is the painstaking detail in process you have to go through to be able to interact with these patients with Ebola. This is as close as we can get. They are decontaminating themselves, but they`ve taken the blood samples and put them in this blue ice chest over here and it`s highly suspicious that contains Ebola.
