CDC Risk Chart

Sep 6, 2012

Dear Dr. Wohl,

I was browsing the site and I took a look at the recent CDC Risk of Infection chat. Everything is laid out fairly well there. I have two questions though.

1) It says thrown bodily fluids is a negligible risk. Does this include blood? Stupid question I know since blood comes from the body but they used saliva and semen.

2) I've read so often that when it comes to thrown fluids and the like that the exchange of fluid has to be immediate. Does that mean an exchange of fluids has to take place in minutes or seconds when it comes to body fluids outside of the body? Just curious. Also would that have an impact on transmission seeing as how the risk is sited as negligible anyways?

Response from Dr. Wohl

The virus has to get past all our defenses to get into the body, find the right cells and multiple. Thrown blood unless we are talking you taking on the role of Sissy Spacek in the final prom scene of Carrie, should not lead to infection even if infectious.

The older the fluid is, the less viable the virus within.


Last confirmation from previous question, HIV and Urethra (pee hole), please help me doc!!
eia non reactive, then reactive, then the third time do not know.
