As many of us are starting to make travel plans back to our
hometowns for Thanksgiving, one thing that may be on our minds is how safe is
it to travel on airplane these days. With Ebola still making many media
headlines, the thought of potential infection is still a scary one that many of
us have. Airplanes are particularly a source of concern, with recycled air and oftentimes lack of thorough sanitation.
Professor James Barbaree of Auburn University has long
studied bacteria on airplanes. From what he has discovered, when improperly
cleaned, many of the airplane surfaces, such as chairs, tray tables, toilets,
etc, can all harbor bacteria pathogens for sometimes more than a week. When it
comes to Ebola though, the CDC has said that at least on surfaces, Ebola is only
able to survive for a few hours. However, if the virus is in some sort of
bodily fluid, the virus survival time is extended to several days.
The CDC also claims that Ebola can only transmitted to
another person if the infected person is exhibiting symptoms, such as fever.
The viral titer in a patient drastically increases as the patient becomes more
and more ill, and experiences more symptoms, making their bodily fluids that
much more infectious. The spread of Ebola only happens through direct contact with
bodily fluids containing the virus. By properly disinfecting with hospital
grade disinfectants, such as bleach, it is possible to inactivate Ebola virus.
Given all this information, the CDC supports that the
chances of being infected by an Ebola carrier who has no symptoms is low. Given
this information, should we be screening people who board planes for fever and
other symptoms? Director of the National Institute of Allergy and Infectious
Diseases, Anthony Fauci, believes it is worth our time to continue screening.
While screening patients for Ebola might not help curb the spread of the virus
to other countries, as intended, if the patient doesn't develops symptoms after they
exit the plane, perhaps what the screen can be useful for is preventing the
spread of disease to people on the airplane itself. At least if nothing else,
screening people may reduce any panic people may have about contracting Ebola while traveling home for Thanksgiving!

5 years ago I had warts, I was treated with some liquid applied to the warts they continued to grow and spread... The next 2 doctors did laser surgery to remove them. 1 year after the surgery, they grew back close to where the 1st ones were' so I was finally told it was hpv.
