Bill Gates says one way to prevent the spread of Ebola and other diseases in Africa is to make basic health interventions more readily available.
In an exclusive interview with Ozy.com, Gates told CEO Carlos Watson: "Most people in Africa are born and die without ever meeting what we’d think of as a full-blown doctor.”
Watch the clip above as Watson spoke about this and other takeaways from the interview on "New Day" Friday.

As fears of an Ebola outbreak in the U.S. increase, big cities are getting creative in how they're preparing for the worst.
Dr. Ross Wilson, the Chief Medical Officer for the NYC Health and Hospitals Corporation, tells CNN's Michaela Pereira they are sending actors to public hospitals in the Big Apple to fake symptoms of Ebola in order to test how well the staff identifies and isolates possible cases.
Dr. Wilson describes the process:
"We train simulated patients and then we take a standard script, they arrive at an emergency department and staff are unaware that these patients are not real patients, and this goes through for about 50 to 60 minutes until the patient is isolated or we end the scenario."
So what should the hospital staff be looking for and what is the proper response?
Two simple things, Dr. Wilson says.
"Someone comes in with a headache, symptoms of vomiting, diarrhea, and a fever, immediately get a travel history."
If the person has been to the three countries in Western Africa – Sierra Leone, Guinea, or Liberia, they are immediately isolated.
And how is New York City doing?
Dr. Wilson is optimistic.
"We’ve been gratified that most things have gone right," he says.
"But there are a lot of human beings in this process and they all have to come together in the same way every time, with every patient."

Rob Portman, a Republican, is a U.S. senator from Ohio. The opinions expressed in this commentary are his.
With the news that a Liberian citizen has been diagnosed with Ebola on U.S. soil, the Obama administration must finally act to ensure that the disease does not spread further.
For weeks, I have been calling upon the administration to take a robust, proactive approach to prevent Ebola from becoming a public health crisis here in the United States. These steps include appointing a single, accountable official to coordinate with the many agencies tasked with containing the Ebola epidemic, and moving from passive to active screening at U.S. ports of entry for all passengers traveling from countries with known outbreaks of Ebola.
These common sense steps, while not foolproof, would go far in preventing an outbreak of Ebola and assuring the American people that their leaders are not taking the threat of this disease for granted.
