Hannelore??

<< < (6/17) > >>

est:
I think that it's been covered pretty comprehensively at this point.

Jim789:
Hrmm i've advoided using this forum for years, i've been reading the comic for a long time.

But something Hanners said in the last comic was very wrong.

Blood does not carry pathogens, it is sterile. Very clean (usually) when it is carrying pathogens that person is septic and in trouble!

Vendetagainst:
well no, blood still contains pathogens, otherwise it would not need leukocytes.

Is it cold in here?:
This is important and will be covered in any first aid class. There are some all-too-common bloodborne pathogens like hepatitis, and some really scary ones like HIV. See http://www.pp.okstate.edu/ehs/modules/bbp/index.htm or other resources. Blood banks need to be really careful not to let anything infectious into their inventory: that's why they ask if you've had a cold or flu recently.

Now, avoiding your own blood is a little over the top... But blood is anything but sterile.

Jim789:
Blood is a sterile site, as is most of your inards. Your gastinotenstinal tract is not, you have normal flora, also your skin has normal flora.

White blood cells are in your blood at all times, and are transfered around the body to sites that need them... like a wound or infection, or a virus etc.
Blood pathogens such as hepatitis i didnt think about, so vriuses could be there... but when would hanners have gotten something like hepatatis or HIV?

Any bacteria or fungus in blood will and always will be bad.
