head of the World Health Organization talked about Ebola:
a scary infectious disease. But the first thing you should know is that
it's not very contagious --
the virus isn't spread through the air via coughs or
sneezes like the common cold.
It's spread through frequent contact with bodily fluids
and can be spread only by someone who is showing symptoms.
So if they're not feeling sick ...
Many viruses can hide in the body and spread from person
to person without causing any symptoms in the people it infects. Ebola
isn't like that.
"Ebola doesn't spread before someone gets sick," Dr.
Thomas Frieden, director of the Centers for Disease Control and
Prevention, said Tuesday. "Ebola does not spread ... from someone who
doesn't have fever and other symptoms."
Symptoms generally occur abruptly eight to 10 days after
infection, though that period can range from two to 21 days.
As people with the Ebola virus become sicker, they become
more infectious, experts say. The virus can also spread through bodily
fluids after the patient dies.
And by 'bodily fluids,' you mean?
Blood, sweat, feces, vomit, semen and spit.
Basically any kind of fluid that comes from the body. People in West
Africa are avoiding hugs and handshakes because the virus can be spread
through the sweat on someone's hand.
So we are trusting someone who says it canít be spread by
cough or sneeze. But it can be spread by spit and sweat. I kind of thought
those were similar saliva contamination. I am still not convinced that it
is not contagious until there is fever. HIV is contagious 5 years before
symptoms. I cannot find any reported medical studies that prove the time
patients are contagious. Who knows!
I still think we do not know how many people in Africa get
Ebola and not die. Probably there in Africa Mortality is high but with
modern therapy here it probably is less. Mortality in Africa outbreaks have
ranged from 37% to 80%. It still is a bad infection and we donít want it
here. I pray that none of the people exposed here come down with it.
I wonder how many healthcare workers, who are over cautious
and still getting infections, are acquiring it from foods. Their food
handling sanitation is probably terrible in Africa.
Do not be overly concerned about this disease at this time.

Well we finally had our first case of Ebola acquired in
America. You heard of the nurse that came down with it. She went to the
hospital with symptoms and after 1 Ĺ hours was admitted to isolation.
Spreading the virus for a time. Why did she not call from home and say she
was exposed and ill and to come get her. They then could have put her is a
suit at home and transported her safely to ICU and Isolation. I wonder how
long the first index case man who went to the ER, was sent home, then went
back to the ER, and was finally suspected of having Ebola. How long was he
exposing hospital workers until he was put into isolation. This nurse
either did not follow isolation techniques carefully or (as I think) was
exposed to it before they put him into isolation. Hopefully with our better
therapy she will be OK. And they are now starting human trials of a vaccine
and it will be in high gear to rush to market through the FDA.
