If you’ve been reading the news lately, you might have noticed an odd piece of reportage from CNBC, in which a naturopath claimed that antibiotic-resistant gonorrhea “might be a lot worse than AIDS” and might cause cases of sepsis that could kill “in a matter of days.” This quotation, uttered by a single naturopath, was then exaggerated in sources such as the United Kingdom’s Daily Mail, which ran the headline “Doctors warn that antibiotic-resistant strain of gonorrhea could be ‘worse than AIDS.’” In fact, the only person making this claim was one naturopath, not a doctor, and certainly not plural “doctors.”

There’s a lot to unpack here. First is the alarmism in the original CNBC article, and its dependence on an unreliable source. Second is the issue of antibiotic-resistant gonorrhea itself, which is a very serious public health problem. Thirdly, let’s look at the naturopath’s claim, which is that antibiotic-resistant gonorrhea could unleash a plague worse than AIDS and kill its victims in a matter of days.

Claims that antibiotic-resistant gonorrhea will be “worse than AIDS” are greatly exaggerated.

Alan Christianson, the naturopath behind the hyperbolic claims of super-virulent gonorrhea, does not seem to be an actual expert in infectious disease (his website lists “natural endocrinology” and “male menopause” among his specialties), nor is he a medical doctor. The article identifies him as a “doctor of naturopathic medicine,” but what does that mean?

Naturopaths are not medical doctors, and degrees in naturopathic medicine aren’t awarded by institutions accredited by the Association of Medical Colleges, the body that accredits medical schools. Naturopathy is a philosophy that is not generally supported by scientific evidence, but rather is based in “a belief in the healing power of nature,” according to the National Center for Complementary and Alternative Medicine. It was developed in the 1800s and today encompasses many modalities of alternative medicine, including homeopathy and herbalism. For these reasons, it is odd that a journalist quoted a naturopath on the potential of antibiotic-resistant gonorrhea rather than someone more qualified, such as a microbiologist or epidemiologist.

We’ve all heard various conspiracy theories; we may or may not find them credible, and we might chalk up opposing viewpoints to simple differences in opinion. Sometimes, however, conspiratorial narratives are woven around matters of life and death — and in such cases, the spread of such ideas can influence dangerous changes in behavior and even government policy.

AIDS denialism is based on the idea that human immunodeficiency virus (HIV) does not cause AIDS. Although the existence of HIV and its causal connection to AIDS has been thoroughly demonstrated by scientists, denialists either reject the existence of HIV altogether, or cast it as a harmless virus that doesn’t cause illness. Denialism often relies upon rhetorical strategies that are superficially convincing but intellectually hollow, including the cherry-picking of evidence, appeals to unreliable “experts,” and untestable claims. Denialists also might cite early AIDS research from the mid-1980s while ignoring more up-to-date findings and improved medical procedures. Such rhetoric creates a sense of legitimate debate in an area where there is none, and the only new evidence welcomed into the discourse is that which confirms preconceived notions.

Health decisions must be shaped by the best available evidence, and when denialism misinforms, one cannot make an informed decision.

If AIDS isn’t caused by HIV, what do denialists claim is behind the unique symptoms that characterize it? Some say that conditions such as malnutrition, or diseases that have been around for a long time, are simply being labeled as AIDS. Other denialists cast antiretroviral drugs as the cause, rather than the preventive treatment, of AIDS. Some claim that AIDS is caused by behavior, such as drug use or promiscuity — with some even saying that an accumulation of semen in the anus can cause AIDS. None of the claims is true — while AIDS can leave someone vulnerable to a wide variety of diseases, and while sharing IV equipment and engaging in unprotected sex can increase risk, there is only one cause: HIV.

GYT2013April is upon us, and you know what that means. It’s STD Awareness Month, so it’s time to GYT. Time to what?

Get
Yourself
Tested

GYT is a national campaign collaboration between Planned Parenthood, Centers for Disease Control and Prevention (CDC), MTV, and Kaiser Family Foundation, which aims to bring greater awareness to STD testing. As part of GYT, Planned Parenthood Arizona wants to make it as easy as possible for you to be screened for sexually transmitted diseases. That’s why participating PPAZ locations are offering a $35 discount on full STD screenings throughout the month of April. Visit us at select health centers in the Phoenix metro area, Tucson, Flagstaff, and Prescott Valley.

In April, participating Planned Parenthood Arizona locations offer discounted full STD screening.

STDs can be transmitted by sexual activity — vaginal, anal, or oral sex, as well as activities that involve skin-to-skin contact. You might think you don’t need to be tested for STDs, but if you are sexually active, STD screening is an important part of maintaining your sexual health — in fact, the CDC recommends it. Most people with STDs don’t have symptoms — no telltale sores, blisters, bumps, warts, or discharge; no itching or burning — which means that it’s possible to have an STD without being aware of it:

  • 3 out of 4 women with chlamydia have no symptoms, and half of men with chlamydia have no symptoms
  • 80 percent of women who have gonorrhea have no symptoms
  • HIV symptoms usually take around a decade to appear

STD Awareness: 10 Myths About Sexually Transmitted Diseases

Posted on by

The Internet is brimming with contradictory claims about sexual health, and you don’t know what to believe. Your friends give you advice, but you’re not sure if it sounds right. To make things worse, you might not have had evidence-based, medically accurate sex education in your school. In this edition of our STD Awareness series, we’ll take on a few myths about sexually transmitted diseases to help you sort fact from fiction.

1 MYTH: You can tell if someone has an STD by looking at them.
You might expect that if someone has an STD, their genitals would have blisters, warts, or noticeable discharge. But your partner looks fine, so you might think there’s no need to ask when his or her last STD test was.

However, while many people with STDs do have visible symptoms, they’re the exception rather than the rule. For example, three out of four women and half of men with chlamydia have no symptoms. Herpes is often spread when there are no symptoms present. Someone can be infected with HIV — and capable of transmitting it to others — and go years without showing any signs. A quick visual inspection can’t tell you very much about someone’s STD status.

2 MYTH: You can’t get an STD from oral sex.
While it is generally true that oral sex presents less of a risk for contracting STDs, this risk is not trivial. Most STDs can be passed along by oral sex, including chlamydia, gonorrhea, syphilis, hepatitis B, herpes, human papillomavirus (HPV), and HIV. You can reduce your risk by using barrier methods like condoms and dental dams consistently and correctly.

3 MYTH: Condoms can’t prevent the spread of HIV.
Many proponents of abstinence-only education state that condoms don’t protect against HIV, claiming that latex condoms have holes that are large enough for viruses to pass through. This claim isn’t backed by evidence. An intact latex condom dramatically reduces your risk of being exposed to sexually transmitted viruses such as HIV. (It is true that a lambskin condom does not provide adequate protection against HIV.) Continue reading →

How Does HIV Cause AIDS?

diagram of a human immunodeficiency virus

Last week, we gave a general background of human immunodeficiency virus (HIV), the virus that causes AIDS by destroying the immune system. But how is HIV able to disable our immune systems so effectively, anyway? The answer lies in its structure.

HIV, just like any other virus, is made up of a tiny capsule with a small piece of genetic code inside. While most viruses we’re familiar with store their genes on a molecule called DNA, HIV contains two pieces of RNA, which is another type of gene-storing molecule. The HIV capsules also contain an enzyme called transcriptase, which “translates” the RNA into a strand of DNA that our cells can read. Our cells are then tricked into reading this DNA and producing more copies of the virus — which are then released from the host cell, at which point they are free to infect other cells. In this manner, an HIV infection slowly grows.

HIV targets our immune systems, the very mechanism that evolved to keep us safe from pathogens.

When a virus is introduced into a host’s body, immune cells pick it up and carry it to the lymphoid organs — which are a sort of meeting place for other types of immune cells, including CD4+ T helper cells (also called helper T cells). Helper T cells enlist the help of other immune cells, called killer T cells, which destroy cells infected with viruses. Helper T cells also activate the production of antibodies, molecules that are specialized to attach to a specific pathogen so that it can be destroyed. Normally, this is where the virus meets its end. Unfortunately, HIV is different from run-of-the-mill viruses in that it is specialized to invade helper T cells. Now, instead of coordinating an attack against HIV, the helper T cells have been hijacked — converted into factories for the production of yet more HIV. Continue reading →

STD Awareness: HIV and AIDS

Our immune systems are beautiful things, refined through millions of years of evolution. The immune system’s complexity is testament to the “arms race” that has been taking place between our species and the harmful pathogens that surround us. Last century, a virus called human immunodeficiency virus (HIV) emerged, and it found a weak spot in our immune system’s armor. HIV has been exploiting this weakness ever since, and an HIV infection can eventually progress to a disease called AIDS, or acquired immune deficiency syndrome. AIDS is a condition that disables our immune system’s ability to function properly, rendering us vulnerable to a host of opportunistic infections and cancers.

Even if you don’t think you’ve been exposed, HIV testing can be a good idea.

HIV is transmitted via bodily fluids: blood, semen, pre-seminal fluid (which can be present without ejaculation), breast milk, vaginal fluids, and rectal mucus. (It can also be present in bodily fluids like amniotic fluid, cerebrospinal fluid, and synovial fluid, to which health-care workers might be exposed.) The virus is not transmitted by fluids like snot, saliva, sweat, tears, and urine — unless blood is present.

Activities that can bring you into contact with HIV-infected bodily fluids include injection drug use and sexual activities like anal, vaginal, or oral sex. It can also be transmitted to a fetus or baby during pregnancy, childbirth, or breastfeeding. In the early days of HIV, many infections occurred as a result of blood transfusions or organ transplants — though nowadays this is a rarity thanks to tissue screening. Lastly, health-care workers might be exposed to HIV through accidents involving needlesticks or cuts. Continue reading →

“I Didn’t Want to Believe It”: Lessons from Tuskegee 40 Years Later

Posted on by

Located among longleaf pine and hardwood trees, low ridges, and broad floodplains, Tuskegee, Alabama, is a small town that’s been a big part of American history. Despite a modest population of less than 10,000 people, Tuskegee has been able to boast many notable residents who have made names for themselves in everything from sports to the arts. Among them have been the Tuskegee Airmen, the first African American Air Force unit, which served during World War II, and Rosa Parks, the icon of the civil rights movement, who sparked the Montgomery bus boycott in 1955.

The Tuskegee syphilis experiment, conducted from 1932 to 1972, examined the natural progression of untreated syphilis in poor, rural black men — without their informed consent.

Tuskegee, though, is also remembered for one of the worst chapters in the history of medical research. Forty years ago, in 1972, newspapers revealed the story of a syphilis study that was callous in its deception of research participants, and damaging, even today, in the distrust it sowed among black Americans. The study had started another 40 years prior, in 1932, when the United States Public Health Service (USPHS) needed to rescue a financially troubled syphilis intervention in Macon County, Alabama. The intervention was first established in partnership with a Chicago-based philanthropic organization, but its future was uncertain when the organization’s funds dried up during the Great Depression.

Syphilis, the sexually transmitted disease caused by the bacterium Treponema pallidum, was the subject of conflicting scientific hypotheses at the time, including the hypothesis that the disease behaved differently in blacks and whites. Interested in testing those hypotheses and faced with disappearing funds for treatment, the USPHS turned its project into a study of untreated syphilis. Also influencing the decision was the fact that the USPHS was discouraged by the low cure rate of the treatments at the time, mercury and bismuth. But by the mid-1940s, penicillin was in use as a proven treatment for syphilis. In spite of that medical advance, the USPHS withheld treatment from a total of 399 infected patients by the time the study ended in 1972. Continue reading →

STD Awareness: “What Are the Symptoms of an STD?”

“I was treated for chlamydia, but my girlfriend feels fine, so she doesn’t need to get tested.”

“The only time I don’t use condoms is for oral sex, and everything’s been OK ‘down there,’ so getting tested for sexually transmitted diseases would be pointless.”

It’s important to be able to recognize the symptoms of a sexually transmitted disease (STD). Being savvy about symptoms can push you to get tested right away if you notice that something is amiss. However, being symptom-free can lull you into a false sense of security, especially if you’ve engaged in sexual activities that could have exposed you to an infectious agent. The fact of the matter is that many people with STDs have no symptoms at all. As they say, “The most common symptom of an STD is … no symptom.” Let’s take a look at some common STDs.

The most common symptom of an STD is no symptom.

Bacterial Infections

Bacterial STDs are curable with antibiotics. They include chlamydia, gonorrhea, and syphilis — all of which can be asymptomatic, and all of which can have severe complications when they are not treated in time.

Chlamydia: Around 3 million Americans are infected with chlamydia annually, and the infection is especially common among young people (less than 25 years of age). Chlamydia can infect the penis, vagina, cervix, anus, urethra, eye, or throat. You can be afflicted with a range of symptoms: pain or a burning feeling while urinating; vaginal, cervical, or penile discharge; swelling around the anus, testicles, or vagina; and more.

However, you’re much more likely not to experience any symptoms at all — most people with chlamydia are unaware they have it. Three out of four women with chlamydia have no symptoms, and half of men with chlamydia have no symptoms. Left untreated, chlamydia can become a serious health threat. Long-term complications might lead to fertility problems and arthritis. Continue reading →
