Some Gen Xers Might Need Measles Booster Shots

Measles, a disease declared eradicated in the U.S. in 2000, is making a comeback. As of Wednesday, April 24, there were 695 measles cases in 22 states, according to the CDC. As public health officials implore parents to get their kids vaccinated, some adults are wondering if the shots they received years ago are enough to keep them safe.

As WECT reports, adults born between 1957 and 1989 may benefit from getting a measles vaccine booster, even if they received the vaccine when they were kids. Many Baby Boomers and people from older generations were likely exposed to measles as children, and are therefore immune to the virus. But measles rates have dropped since 1963 when the measles vaccine was first introduced. In 1989, the CDC began recommending two doses of the vaccine for kids, spaced out over a few years, for maximum effectiveness.

CDC guidelines for measles vaccines haven't changed since the current outbreak began. The department says that anyone born after 1957 should have received at least one dose of the vaccine, which is 93 percent effective against the disease. But if Gen Xers want to be extra cautious, they can ask their doctor to test their antibody levels to see if they're immune. If they're still vulnerable to measles, they can get a second booster shot, which together with the initial vaccination is about 97 percent effective.

But the CDC's current priority is children who haven't been vaccinated at all. Thanks to the misinformation around vaccines, a growing number of parents have opted not to get their kids vaccinated, which has fueled the current health crisis in the U.S. According to a 2016 review of measles studies, out of 970 measles cases, almost 42 percent of patients had skipped the vaccine for non-medical reasons.

The symptoms of measles range in severity from a rash around the hairline to coma and brain swelling. The CDC warns that the longer this current outbreak continues, the greater the chance is that measles will stay in the U.S. for good.

9 Surprising Facts About the Scientific Study of Sex

The scientific study of sex is much more exciting than an awkward sex ed class. While writing my book Sex Weird-o-Pedia, these were some of the most interesting facts about science and sex that I came across.

1. Some sex researchers didn't want their findings to get into the wrong hands.

The pioneering sex researcher Richard von Krafft-Ebing didn’t want his knowledge in the hands of ordinary folk. So he wrote Psychopathia Sexualis, the founding document of modern sexology—which was published in Germany in 1886 then translated and published in English in 1939—in Latin to discourage regular Joes (and/or Janes) from reading it.

2. You burn more calories mowing the lawn than you do having sex.

Sex might seem strenuous when things get hot and heavy, but it's usually not that great of a workout. You'd have to go at it for nearly 200 minutes to burn as much energy having sex as you do during a 30-minute run. Even mowing the lawn burns about three times more calories than sex. According to the British Heart Foundation, sex burns about the same amount of energy per minute as ironing clothes.

3. A surprising number of mothers claim to be virgins.

In a 2013 study of several thousand pregnant women in the U.S. published by BMJ, about 1 percent of the participants claimed they were virgins when they gave birth. This, of course, calls into question the veracity of studies that rely on self-reported sexual behaviors.

4. Penicillin may have ignited the sexual revolution.

One economist says that penicillin, and not the birth control pill, was the real enabler of the sexual revolution. A study published in the Archives of Sexual Behavior in 2013 shows that penicillin contributed to a 75 percent decline in the number of deaths caused by syphilis from 1947 to 1957. Since the new treatment made sex safer, people started having riskier sex, which resulted in increases in the numbers of children born out of wedlock and teenage pregnancies.

5. Twins can have different dads.

While it is very rare, it is possible for fraternal twins to have two different fathers. What’s more common is for a rom-com to be based on this scenario.

6. Gender may influence how people handle sexual jealousy.

Research from evolutionary psychologists indicates that people’s gender influences how they react to sexual jealousy. For men, they react more strongly to sexual unfaithfulness than emotional infidelity. For women, it is the reverse. The theory behind these behaviors comes back to evolution: Males who were intolerant toward their wives becoming sexually active with other men were less likely to become an object of derision and more likely to see their own genes pass onto future generations. Women who prevented their husbands from emotionally bonding with other women reduced the chances of the men spending their resources on other women.

7. One of Ivan Pavlov's colleagues created his own (slightly x-rated) conditioning experiment with dogs.

You’re probably aware of Russian researcher Ivan Pavlov and his famous conditioning experiment in which he trained a dog to salivate at the sound of a bell. What you might not know is that one of Pavlov’s American students, W. Horsley Gantt, conditioned dogs to become sexually aroused when they heard specific tones. The experiment, according to Mandy Merck's In Your Face: 9 Sexual Studies, was intended "to study conflicts of the drives between ... experimentally induced anxiety states and sexual excitement."

8. Couples whose first child is a girl are more likely to get divorced.

Married couples whose first child is a girl are more likely to get divorced than those whose first child is a boy. Scientists are split as to why this is. One theory is that female embryos are better able to endure maternal stress than male embryos, so pregnant women in unhappy marriages are less likely to have a miscarriage if the child they are bearing is a girl. But once they have a daughter, these couples are more likely to split up since there were already fissures in their relationship prior to the child’s birth.

9. There's a link between pubic hair and STIs.

A downside of pubic grooming is that it might raise STI risk. In a study conducted by a University of Texas scholar, people who regularly shaved their pubic areas contracted STIs about 80 percent more often than those who never shaved down there. One suggestion is that those who regularly shave are more likely to tear their skin, making it easier for viruses to enter the body.

Airplane Water Quality Is Even Worse Than Previously Believed

While air travel is convenient, there's never any promise it will be particularly clean. Security checkpoint bins and airplane tray tables are notorious for harboring germs. In addition to being careful of what you touch, you need to be cautious about what you drink.

Air travelers have been warned in the past about the questionable water quality of major airlines. Owing to inconsistent water transport issues, storage methods, and lackadaisical monitoring, several studies and investigations—including a 2004 report by the U.S. Environmental Protection Agency (EPA)—have found bacterial contamination and even insect eggs lurking in liquid served to passengers in the form of coffee and tea.

Unfortunately, the problem doesn’t appear to be getting any better. A new study on the quality of airline tap water conducted by the Hunter College NYC Food Policy Center found E. coli, coliform bacteria, and other unpleasantries across 11 commercial and 12 regional carriers.

The study ranked airlines according to water quality tests, and whether airlines were forthcoming in disclosing how they handle water transportation and storage for in-flight plumbing, using a scale of 1 to 5. While some airlines, like Alaska and Allegiant, scored well at 3.3, others (including JetBlue, Spirit, Delta, and United) ranked poorly in terms of delivering healthy, clean water, which is often sourced from local municipalities.

Low scores also indicated a lack of transparency about the airlines' water monitoring process. Moving the water from its source through hoses and tanks can create opportunities for the water to become contaminated.

How can questionable water be served? While the EPA introduced an Aircraft Drinking Water Rule in 2011 that mandated quarterly cleanings of airplane holding tanks and bacteria tests, Condé Nast Traveler reports that the agency does little to enforce it, typically opting not to issue fines to airlines found to be in violation of the terms.

The study’s authors recommend people avoid drinking tap water, coffee, or tea while on airplanes and should instead opt for bottled water. Because the stored water is also used for lavatory sinks, it’s possible you might introduce germs to your hands even after “cleaning” them. Hand sanitizer is recommended.
