Patients Diagnosed with HIV Are Living Long, Healthy Lives, Thanks to Vastly Improved Testing and Treatments
HIV (human immunodeficiency virus) infection still has a long way to go before it can be declared eradicated from the planet. However, vastly improved testing and treatment have changed the face of the disease, transforming it from deadly to manageable.听
An estimated 1.2 million people in the U.S. are HIV-positive, according to the most recent data from the Centers for Disease Control and Prevention (CDC), but approximately 13 percent of that number are unaware of their diagnosis. 罢丑补迟鈥檚 a problem, says Dr. Benjamin Scallon, a primary care internist and Assistant Professor of Clinical Medicine at 麻豆传媒高清版.听
Knowing your HIV status is the key to unlocking the behaviors, tests and medications that will keep you safe and healthy, Dr. Scallon says.听听
The U.S. Preventive Services Task Force鈥攁n independent, volunteer panel of national experts in disease prevention and evidence-based medicine鈥攔ecommends getting screened at least once for every single person alive. The task force, along with primary care and infectious disease specialists across the country, recommends more frequent testing for people at higher risk of contracting HIV.听
How is HIV transmitted?听
HIV can be transmitted only through specific bodily fluids from a person who has the virus. These include:听
- blood听
- semen听
- rectal fluids听
- vaginal fluids听
- breast milk听
For transmission to occur, these fluids must come into contact with the mouth, vagina or rectum or be injected directly into the blood stream. HIV is most commonly transmitted through the sharing of needles to inject drugs or through anal or vaginal sex.听
Who is at risk?听
According to the most recent data from the CDC, the following groups are at disproportionate risk for contracting HIV:听
- Gay, bisexual and other men who have sex with men (MSM)听
- Black, Latino and Indigenous men听
- Black women听
- Transgender women听
- Youth aged 13鈥24 years听
- People who use injection drugs听
Regarding the last group on the list, the opioid epidemic has led to an increase in HIV incidence鈥攏ew infections鈥攄ue to a rise in injection drug use. Sharing needles is a risk factor for contracting HIV, as well as hepatitis B and C.听
The importance of getting tested听
Some people are still reluctant to get tested, says Dr. Scallon. 鈥淭hat, at least in part, has to do with the stigma associated with HIV infection.听听
鈥淎necdotally,鈥 he continues, 鈥渟ince moving to New York City, I鈥檝e noticed that more and more patients are willing and eager to seek screening, even if they don鈥檛 fall into a 鈥榟igh-risk鈥 category. It鈥檚 encouraging to see New Yorkers act collectively for the greater good.鈥听
Regrettably, there are still people who are reluctant to get screened, despite major advances in prevention and treatment.听
What preventive measures can people take to avoid contracting HIV and protect others?听
It鈥檚 crucial for patients to know their status. HIV treatment has advanced light years over the past several decades, Dr. Scallon says. Patients living with HIV can expect to have normal life expectancy, if they鈥檙别 maintained on highly active anti-retroviral therapy (HAART). Their viral load will drop to negligible levels, with a zero percent chance of passing the virus to their partners.听听
The best ways to prevent HIV infection are:听
- Get tested often.听听
- If you have suspected ongoing exposure to the virus, you can and should take a medication called pre-exposure prophylaxis (PrEP).听
- If you use injection drugs, take advantage of a clean needle exchange program and seek treatment for opioid use disorder.听
PrEP and PEP听
When taken consistently, PrEP can prevent HIV infection. However, people on this medication still require regular, frequent monitoring of their HIV status. If used inappropriately by patients who already have HIV, PrEP can be harmful and even induce resistant strains of the virus.罢丑补迟鈥檚 why it should only be used by people who are HIV-negative.听
There鈥檚 also a medication called post-exposure prophylaxis, or PEP. People who have already been exposed to HIV, or suspect as much, are urged to take PEP as soon as possible, preferably within 48 hours of exposure.听
The HAART of the matter听
Large-scale prospective studies of patients with HIV on today鈥檚 anti-retroviral therapy (HAART) found no transmission of the virus to their sexual partners. Zero.听听
鈥淲e call that phenomenon U equals U, which means 鈥榰ndetectable=untransmissible,鈥 Dr. Scallon says. As long as patients remain on HAART, it鈥檚 almost as if they don鈥檛 have HIV. Their viral load drops to zero, and their ability to transmit it drops accordingly.听
U=U lends further support to the idea that the most important step in preventing and, eventually, eradicating HIV is knowing everyone鈥檚 status and offering anti-retroviral therapy to all who need it.听
The persistence of stigma听
HIV disproportionately effects disadvantaged groups who have been historically ostracized, both within the medical community and by society at large, Dr. Scallon explains. But accepting stigma as a permanent feature of society is unwarranted.听
鈥淪ocieties that are more inclusive and tolerant do better than repressive, punitive societies,鈥 he says. 鈥淭he positive impact of harm reduction policies is clear, based on all available evidence. The more open we are as a society with respect to safe sex practices and safe intravenous drug use, and the more we support the use of medications like PrEP and anti-retrovirals, the lower the HIV positivity rate will be.鈥听
Toward eradication听
However, a greater effort will be needed to eradicate HIV in the U.S., focused mainly on testing and treatment. Globally, says Dr. Scallon, there are regions where homosexuality is criminalized and punishment of drug use is draconian. These societies continue to experience far higher rates of HIV incidence compared to more tolerant societies.听
Still, we鈥檝e made enormous progress in decreasing the numbers of HIV infection through testing and treatment. To benefit from these advances, it鈥檚 critical to know your HIV status. If you haven鈥檛 gotten tested yet, it鈥檚 time to step up and make the decision to get tested ASAP.听
