How can a person with anxiety and OCD overcome the phobia of infectious diseases?

Hello doctor,

I have anxiety and OCD disorder and an extreme phobia of infectious diseases. So I need your help to understand a few doubts: Is that a risky exposure if someone touches HIV-infected fluid (semen or blood), which is wet and has not dried up? I understand that intact skin is a good barrier to this, but what if someone touches any mucous membranes after touching the wet liquid?

Hi doctor,

And the fluid is dried up, then? I mean to say, if one can notice that the hands are totally dry. But, even then, is there any risk?

Hi doctor,

When we wash our hands with soap, is contact time more important than scrubbing?

Hi doctor,

No, not visibly dirty. I have this phobia, so after touching anything from the outside, like a parcel or public seating area or anything, I wash my hands like I am washing off HIV and infected fluid from my hand, and I scrub a lot. So to kill HIV, hand scrubbing or contact time is important.
