Welcome to the forum. Thanks for your question, which arrived while I was logged in; most users should not expect nearly real-time replies! 

Perhaps I don't understand the construction business, but I really don't envision much opportunity for direct contact with co-workers' blood. And there has never been a known case of HIV that was acquired by contact with someone's blood in the workplace or after the kinds of exposures that might occur in construction. One can imagine a theoretical scenario of transmission -- e.g. an injury with something sharp (a nail? a tool?) that had very recently (within a minute or so) injured another worker and still had wet blood, AND if the previously injured person happened to have HIV, AND if that person had a high viral load. But obviously the chance of these things is extremely low. As for your second question, multiple exposures obviously increases risk compared with one exposure. But still, with no known cases of HIV from such exposures, anywhere in the world, obviously the risk remains virtually zero regardless of frequency of such events.

Those comments address both your questions. You avoid HIV by having only safe sex and not sharing drug injection equipment with other persons. No matter where in the world you live, there are no other risks you need to worry about.

Let me know if anything isn't clear. Best wishes and stay sexually safe!  HHH, MD

Sir....thanks for reply . 
As you said risk is low . 
1)Does amount of blood make difference in hiv risk??.i mean small and large amount of blood.
2) As you said hiv risk is low and there are no known cases , if a person gets exposed to other person blood ( small or large) one time or multiple times, would you recommend hiv testing??

3) when you say hiv risk is not known or hiv risk is low. It means even if a person gets exposed to other person's  blood ( large or small amount ) one time or multiple times , chances of getting hiv is rare or low. Is that right??

1) Yes, this makes a difference. If you were to care for a work colleagues after a major injury with heavy bleeding, and if fresh cuts on your hands came in contact with his blood, there might be some risk. Any less than that, i.e. anything you don't notice, is not a sigificant risk.

2,3) This is the same question, asked twice -- and it was already answered above. I do not recommend testing even if you think such unnoticed exposures have occurred many times.

sir ....thanks for reply....i just clarify somethings.

sir i really apologize you  it my question irrates you. it was my doubt

1)  in this construction site i have noticed visible blood from wounds in multiple times . my concern is if i am exposed to noticeable amount of blood to my eyes or wounds directly from another person.  i have seen wounds multiple times . if i am exposed to it multiple times. what is the risk?? would you reccomend testing
2) like you said , in construction field there are no known cases of hiv infection. its very confusing to understand in spite having many injuries , people gets hiv rarely. i heard if you are exposed to noticeable amount of blood, you can get hiv .it is very confusing how hiv spreads or infects

1) Zero risk, for the reasons described above. If nobody in the world has ever been infected in this way, do you really think you might be the first.

2) It really isnt confusing at all. HIV transmission requires much more blood exposure than you have described at construction sites. And for infection to take hold, the blood must have access to certain cells deep in the body.

That completes the two follow-up questions and replies included in each thread on this forum, and so ends this discussion. Please note the forum does not permit repeated questions on the same topic or exposure. This will have to be your last one; future new questions along these lines and your fears about HIV through construction work will be deleted without reply and without refund of the posting fee. This policy is based on compassion, not criticism, and is designed to reduce temptations to keep paying for questions with obvious answers. In addition, experience shows that continued answers tend to prolong users' anxieties rather than reducing them. Finally, such questions have little educational value for other users, one of the forum's main purposes. I trust you will understand.
