President Barack Obama said the following on September 16 at the Centers for Disease Control and Prevention in Atlanta: “First and foremost, I want the American people to know that our experts, here at the CDC and across our government, agree that the chances of an Ebola outbreak here in the United States are extremely low. We’ve been taking the necessary precautions, including working with countries in West Africa to increase screening at airports so that someone with the virus doesn’t get on a plane for the United States. In the unlikely event that someone with Ebola does reach our shores, we’ve taken new measures so that we’re prepared here at home. We’re working to help flight crews identify people who are sick, and more labs across our country now have the capacity to quickly test for the virus. We’re working with hospitals to make sure that they are prepared, and to ensure that our doctors, our nurses and our medical staff are trained, are ready, and are able to deal with a possible case safely.”

Four days later the “unlikely” occurred: the first person infected with Ebola arrived in the U.S. from Liberia, where he had assisted an infected woman, become contaminated, but did not tell anyone about it in order to get on a plane and travel to Dallas, Texas. It took three different flights for him to get here and no one along the way apparently knew he had been in Liberia, or was able to determine that he had been infected, since he was asymptomatic until after he got here.

After developing a fever, he visited Texas Health Presbyterian Hospital, was treated and sent home, despite having recently been in Liberia. He was staying with relatives in Dallas and as the disease progressed he got sicker and became contagious, and after that he returned to the hospital and was diagnosed with Ebola. Several days later, he passed away.

His relatives were exposed to Ebola, and the residence and outside areas were contaminated. Who knows how many others were exposed to the virus?

Mr. Obama said we can handle this, should the need arise. But the need arose, and a well-respected hospital didn’t handle the first infected person very well at all.

The first airport screenings began Saturday at New York’s John F. Kennedy International Airport in New York. Other airports were to begin screenings this week. Screenings at African airports and another screening at U.S. airports, the president said, would make it unlikely that someone infected with Ebola will get to the U.S.

Given the botched handling of the first Ebola patient in our country, can we believe Mr. Obama? “No matter how many of these procedures are put into place, we can’t get the risk to zero,” said the Centers for Disease Control and Prevention’s Martin Cetron, director of the Division of Global Migration and Quarantine. He told a news conference that these new measures wouldn’t necessarily have detected Ebola in the patient who traveled to Dallas.

Complicating an already unnerving situation, a second case of Ebola at the Dallas hospital has now been confirmed. A female nurse who had cared for the Ebola patient prior to his death was assessed on Friday, CDC Director Dr. Thomas Frieden said, and on Sunday it was confirmed that the nurse has Ebola.

The nurse’s infection is blamed on a breech of protocol. One report said that when removing the protective clothing she was wearing, the nurse inadvertently touched her cheek with her gloved hand, a glove that was contaminated with the virus. And now she has Ebola. And now, the disease has a small, but troubling presence in America.

This second error at this hospital has put other hospital personnel at risk, and may have infected one or more of them. Raise your hand if you believe the U.S. healthcare system really is prepared to deal with Ebola patients.

Even without these errors in handling Ebola in Dallas, it simply makes no sense either to bring potential or actual Ebola patients here, or allow people from countries where the disease exists to come here. Why take the chance of exposing Americans, particularly healthcare workers, to this vicious disease?

Columnist Thomas Sowell outlines the situation: “There was a time when an outbreak of a deadly disease overseas would bring virtually unanimous agreement that our top priority should be to keep it overseas. Yet Barack Obama has refused to bar entry to the United States by people from countries where the Ebola epidemic rages, as Britain has done. In other words, the safety of the American people takes second place to the goal of helping people overseas.”

President Obama has a giant blind spot when it comes to protecting the country from illegal entry of who knows who through the southern border, and now that blind spot extends to failing to stop people potentially infected with Ebola from coming into the U.S.

In situations like this one, we need to be smart, not compassionate. We can help the unfortunate West Africans by sending medical supplies and assistance without needlessly putting ourselves at risk. And we must.
