Hello, I would like to receive your valuable confirmation.
A small amount of blood which is NOT visible by eyes on any surface or object (such as toothbrush, razor blade, cup, plate, chair, …) cannot cause any risk of HIV, right?
Hello and thanks for reaching out to the AIDS Vancouver Helpline with your question.
When HIV is exposed to air it is not transmittable. Below is a transmission equation which shows that for HIV transmit it require direct access to your blood stream.
|• blood (including menstrual)||• unprotected anal or vaginal intercourse||• vagina|
|• semen||• sharing needles||• anus|
|• pre-cum||• mother to child (in specific cases)||• urethra in the penis|
|• rectal secretions||• open cuts and sores (in theory)|
|• vaginal fluids||• other mucosal membranes|
|• breast milk||• points of needle injection|
As you can see from above there has to be an activity exchange of body fluids and direct access to your blood stream for transmission to occur. Our Helpline Online Forum has got some additional postings that are related to your question that you can use as additional resource. Other websites include CATIE and thebody.com.
If you have additional questions feel free to contact us again.
