HIV from clinic's garbage bag
Hi,
I was in an AIDS clinic a week ago for asking some quesions. While I was there I have touched garbage bag. There were some bloody cottons and blood drops in the bag. After that just about 10-15 minutes later I went to nearby market, bought a sandwich and ate it without washing my hands. I had canker sore and crack on my lips. Am I at risk? Should I get tested?

@sehec,
CDC sent me an e-mail about it.
''Thank you for your inquiry to CDC-INFO. In response to your questions about if you should get tested or if you are at risk for HIV from contact with dried blood in a clinic, we are able to provide you with the following information.
There is little or no chance that HIV can be spread through contact with dried blood.
CDC studies have shown that drying a high volume of HIV in lab experiments lowers the amount of virus by 90 to 99 percent within several hours. The HIV amounts used in lab studies are much higher than those actually found in a person's blood or other bodily fluids, or elsewhere in nature. This means the chance of actually catching HIV from having contact with dried blood is just about zero.
The only way to know if you have HIV is to get tested. If you think you may have been exposed to HIV, talk to your doctor or healthcare provider. He or she can help you find out if you're infected.''

I just realized that in my country (avrg) 2 people got diagnosed with HIV everyday. But this static includes patients who diagnosed in hospitals as well.
and there were two trash bins in the clinic.

Can we say generally people who visit AIDS clinic are MOSTLY get tested regularly? Which means they would have less viral load than my example. I read some stories in a HIV forum and people who got tested and diagnosed in clinic have MOSTLY low viral load.
if so, HIV virus in blood would be much more less than 700.000. Less than 100.000
70,000 copies per mL after 9 hours = 7000-700 copies per mL.
in 0,01 mL would be 70-7 copies.

I did some math.
We know that after every 9 hours (avrg) HIV viral load decrease 10-100 fold.
700.000 copies per mL after 9 hours would be 70.000-700 copies per mL.
1 mL syringe

so clearly I didn't touch that amount of blood. Maybe %1 of it.
in 0,01 mL blood there would be 700-7 HIV virus copies after 9 hours. in my situation it was 15 hours later. Almost twice. Let's say there would be 450-5 copies in 0.01 blood.
Can 450 HIV virus infect me?
Please god I wish some luck please.

Thank you sehec. But I don't think it can survive up to 7 days. Because Hepatit B can survive 7 days outside of body and everybody agree with that. But for HIV people can't be sure about it. I found the orginal article about it.
'' At the optimum pH of 7.1 the half life of the virus ranged from approx. twenty-four hours at 37 degrees C to no significant loss ''
and
''Drying the virus on a glass surface caused a 5-12 fold decrease of activity.''
CDC says
''The most extensive study on the survival of HIV after drying involved greatly concentrated HIV samples, i.e., 10 million tissue-culture infectious doses per milliliter (31). This concentration is at least 100,000 times greater than that typically found in the blood or serum of patients with HIV infection. HIV was detectable by tissue-culture techniques 1-3 days after drying, but the rate of inactivation was rapid. Studies performed at CDC have also shown that drying HIV causes a rapid (within several hours) 1-2 log (90%-99%) reduction in HIV concentration.''
1 log means 10 times less copies per mL, 2 log means 100 times less copies per mL.
if a HIV patient has 700.000 copies per mL, after several hours (5-11) there would be 70,000-700 copies per mL. not a good news for me.

Condoms are the most effective way to prevent HIV and STDs.
PrEP is used by people with high risk to prevent HIV infection.
Can I get HIV from surfaces, like toilet seats?
Can you get HIV from casual contact, like hugging?
Frequency of HIV testing depends on your risk.
Post-exposure prophylaxis (PEP) may help prevent HIV infection.
