Assessing Transmission Risk by Exposure Type
While talking about HIV hazard, it’s essential to initially build up the four conditions that should happen all together for HIV transmission to happen:
1. There should be body liquids in which HIV can flourish. This incorporates semen, blood, vaginal liquids, or bosom milk. HIV can’t flourish in the outdoors or in pieces of the body with high corrosive substances, like the stomach or bladder.
2. There should be a course of transmission by which body liquids are traded. Essential courses of transmission incorporate certain sexual exercises, shared needles, medical care openness, or transmission from mother to youngster. To avoid HIV / AIDS, click oncohiv.com
3. There should be a method for the infection to arrive at weak cells inside the body. This can happen through a burst or infiltration of the skin or through mucosal tissues of the butt or vagina. HIV can’t infiltrate unblemished skin.
4. There should be adequate degrees of infection in the body liquids. This is the reason salivation, sweat, and tears are impossible hotspots for HIV since the convergence of the infection in these liquids is viewed as deficient. Killing catalysts in salivation (called secretory leukocyte peptidase inhibitors, or SLPIs) are known to enormously lessen HIV’s capacity to flourish.
Deciding if a movement is “great danger” or “generally safe” is, accordingly, reliant upon how productively an action fulfills every one of these four conditions.
HIV Transmission Can Occur After Only One Exposure
Relegating a genuine rate to the “hazard” of a specific action is a precarious business. While insights may propose that there is just a 1-in-200 (or 0.5%) possibility of getting contaminated by such-and-such action, that doesn’t mean you can’t get tainted after just a single openness.

All things considered, a 0.5% “per openness” hazard is intended to show that a normal of one contamination will happen out of 200 individuals who participate in a specific movement. It doesn’t imply that you need to accomplish something multiple times to get tainted.
Recall that hazard gauges depend on two variables and two factors alone—that one individual has HIV and the other doesn’t. Extra co-factors, like existing together explicitly sent diseases (STIs), general wellbeing, and the tainted individual’s viral burden can additionally intensify hazard until an okay movement is out of nowhere significantly higher.
Assessed HIV Transmission Risk Per Exposure
The appraisals beneath ought not to be viewed as conclusive but instead fill in as a way to comprehend the overall danger of HIV by openness type. The numbers depend on a meta-investigation of a few enormous scopes contemplates, which took a gander at per-openness hazard.

Decreasing Your Personal HIV Risk
The motivation behind understanding relative danger is to set up the methods by which to decrease your own danger of disease or the danger of communicating HIV to other people. In many cases, it takes little to alleviate hazards. For instance, the steady utilization of condoms connects to a 20-overlap decline in HIV hazard, while picking insertive fellatio over insertive butt-centric sex brings about a 13-crease decrease.3 Conversely, the presence of an STI or genital ulcer builds the danger of HIV by somewhere in the range of 200% to 400%.
Ostensibly the main factor in evaluating the probability of HIV transmission is the tainted individual’s viral burden. Information proposes that the danger of an HIV-contaminated individual with an imperceptible viral burden communicating the infection is basically zero.4
The system called treatment as avoidance (TasP) unequivocally upholds the utilization of antiretroviral treatment to decrease the infectivity of an individual with HIV. It likewise supports the requirement for early testing to relieve hazards in blended status (serodiscordant) couples.
Knowing your serostatus and that of your accomplice permits you to settle on an educated decision on the most proficient method to all the more likely ensure yourselves—regardless of whether it be to swear off high-hazard exercises, use condoms, or investigate pre-openness prophylaxis (PrEP) as a way to diminish the HIV-negative accomplice’s powerlessness to contamination.
