It's a terrifying disease
for sure. It typically kills 90% of the people who get it, and this
most recent outbreak is the largest in history. But you don't need to
panic, experts say, and you definitely don't have to worry about the two
American Ebola patients who are being treated in Atlanta.
Here are five reasons why:
1. It's fragile.
Ebola is an incredibly
fragile virus. It does not fly through the air with the greatest of
ease. It cannot be transmitted through a cough or sneeze. It doesn't
move easily from human to human like the common cold.
Ebola is aggressively infectious, so people who are infected are highly likely to get sick. But it's not highly contagious.
"The Ebola virus spreads
through direct contact with the blood, secretions or other body fluids
of ill people and indirect contact -- for example, with needles and
other things that may be contaminated with these fluids," said Stephan
Monroe, deputy director of the Centers for Disease Control's National
Center for Emerging Zoonotic and Infectious Diseases.
That's why health care
providers who work in countries without proper protective gear can get
it. That's also why people preparing bodies for burial have gotten it.
2. We know how it works.
Although there is no vaccine and no cure, the one real advantage we have with Ebola is that doctors know how to control it.
Ebola isn't "some
mystical pathogen (with) some bizarre mode of transmission," said Bruce
Ribner, who oversees the special isolation unit that is treating the
patients at Emory University Hospital.
Common-sense hygiene can stop its spread.
"Ebola is a virus that
can be stopped and not spread in hospitals. The stakes are higher, but
it's easily inactivated with typical hospital disinfectants," said
Centers for Disease Control and Prevention Director Tom Frieden.
What to know about Ebola
3. We have the resources to contain it.
The two American patients with Ebola were flown to the United States in a plane outfitted with an isolation pod.
They are being kept in isolation at the Emory hospital with a specialized containment ward, one of four in the country.
In the containment ward,
the vents are specialized. There's an intercom and plate glass that
separates patients from visitors so they don't come into direct contact.
There's a strict protocol on everyone and everything that goes into and
out of the patient's room. Health care workers wear protective suits.
But any major medical
center could really take care of an Ebola patient, said William
Schaffner, an expert on infectious diseases at Vanderbilt University's
School of Medicine.
Most ICUs have isolation
rooms that are used for patients suspected to have tuberculosis, SARS,
Middle East respiratory syndrome or another infectious disease.
Schaffner said that not much would be different for an Ebola patient,
though more stringent precautions might be taken to ensure that health
care workers are following all protocols.
4. Our medical staff is ready.
"We have been training
for this," Ribner said of preparations for the two American Ebola
patients. These doctors know how to handle Ebola and will use an
abundance of caution when working with an infected person.
Medical workers across
the country have also been told to watch out for Ebola symptoms and
question patients who have recently traveled to West Africa. They are
trained to recognize Ebola cases and can quarantine them early, keeping
others from coming into contact with an infected person's bodily fluids
while the disease runs its course.
5. Airports are on alert.
At African airports in
the Ebola-affected region, passengers are being closely screened. Health
experts are watching for people with high fevers. Those who have a
temperature are removed and monitored while doctors test their blood for
Ebola.
When passengers arrive
at the airport, they are required to wash their hands in a chlorinated
solution. Customs agents and passport inspectors are also wearing
surgical gloves when interacting with passengers.
"There is always the
possibility that someone with an infectious disease can enter the United
States," CDC spokeswoman Barbara Reynolds said Monday. "The public
health concern is whether it would spread and, if so, how quickly.'"
What is the risk of catching Ebola on a plane?
At U.S. airports,
trained federal agents also watch for sick passengers. Border patrol is
asking about potential exposure. If someone is sick, agents can remove
them and keep them in the special isolation units kept at many U.S.
airports until the CDC arrives to ask further questions.
Overall, health experts
say, the threat to Americans remains relatively small. In the past
decade, five people have entered the U.S. known to have a viral
hemorrhagic fever, including a case in March of a Minnesota man
diagnosed with Lassa fever after traveling to West Africa. No one else
contracted the disease.
