pls educate us about mechanism of infection

May 15, 2006

hi angel bob i adressed you as an angel becoz you are helping people who are living with fear for the most deadliest thing in this world ie hiv. first i would like to extend you loads of thanks for rendering community service. here goes my question :- i just read from an updated hiv article that hiv just cant penetrate the tough mucous membrane thats located near the tip or opening of the penis(from where we pee)infection happens when involved in unprotected anal or vaginal sex during which penis suffers microscopic cuts and bruises.thats when damaged penis(cant notice with the naked human eye) comes in contact with infectd vaginal or anal secretion and hiv gets into the blood it really true or hiv can simply enter through tip of the penis penetrating the tough mucous membrane even though no microscopic damage was done i mean the intact skin.

Response from Dr. Frascino


The "mechanism of infection" has not changed. Your interpretation of what you read is incorrect. (Or perhaps what you read was itself inaccurate.) The urethra (pee hole) is lined with a mucous membrane. HIV-infected fluids coming into contact with a mucous membrane can result in HIV being taken up by specialized cells in the mucous membrane and transported across the membrane without microscopic cuts or abrasions. The take-home message remains if you can't shield your rocket, leave it in your pocket!

Stay safe. Stay well.
