Does 'Vaginal Seeding' Work? Doctors Say There's Not Enough Evidence

People will do just about anything for their kids. And for some parents of babies born by Caesarean section, that includes swabbing a baby with bacteria from their mother’s vagina. It’s a new idea, but it’s catching on—despite the fact that there’s no evidence that it helps, as several doctors note in the British Medical Journal (BMJ). 

The practice is called “vaginal seeding,” and aims to bolster a newborn’s health with the helpful starter bacteria he or she might have missed by skipping the birth canal. Microbiome is the collective term for the ecosystems of bacteria, fungi, and viruses living on and in your body. As you’ve probably heard by now, not all microbes are bad. In fact, you need a certain diversity and balance of microbes to keep your body functioning. You pick up these microbes everywhere you go, from the doorknob of a hotel room to kissing a friend on the cheek. Most people get their first microbial download as they enter the world. But C-section babies don’t. 

The concept seems sound enough. But, as the authors of the BMJ editorial explain, there’s simply no evidence that vaginal seeding is actually effective or safe.

"Demand for this process has increased among women attending hospitals in the UK—but this has outstripped professional awareness and guidance,” co-author Aubrey Cunnington said in a press statement. “At the moment we're a long way from having the evidence base to recommend this practice. There is simply no evidence to suggest it has benefits—and it may carry potential risks." 

Swabbing a baby transfers all kinds of microbes, both harmful and helpful. And since there’s no catalog of which bacteria are being shared, there’s no way of knowing which pathogens might be causing a baby’s sickness down the line. 

"In some countries, including the UK, we don't test pregnant women for the bacteria group B streptococcus,” Cunnington continued. “This is carried by around one in four pregnant women, and although it poses no risk to the mother, it can cause fatal infections in babies. There are also other conditions that cause no symptoms in the mother, such as chlamydia, gonorrhea, and herpes simplex virus that could be transferred on the swab. One colleague had to intervene when a mother with genital herpes, who had undergone a Caesarean section, was about to undertake this process. Swabbing would have potentially transferred the herpes virus to the baby." 

Hospital staff will also not expect a C-section baby to be vulnerable to the kinds of infections as a baby born of vaginal delivery. “It's important [that] parents tell staff they have performed the procedure, so the healthcare team are aware the baby is at risk of the same infections as a baby born by vaginal delivery," Cunnington added.

The bottom line is that parents and physicians should wait for more data before whipping out the swabs. In the meantime, Cunnington says, they can focus on evidence-based methods of boosting a baby’s microbiome: "Encouraging breast feeding and avoiding unnecessary antibiotics may be more important to a baby's gut bacteria than worrying about transferring vaginal fluid on a swab."

7 Quick Tips for Disinfecting Your Home the Smart Way

With many people spending more time—or virtually all of their time—indoors, it’s natural for thoughts to turn to how to best clean surfaces that might help minimize the risk of spreading illness. Although researchers believe respiratory droplets are the primary way coronavirus is transmitted, preliminary data, which is not yet peer-reviewed, suggests the virus may remain on some surfaces for hours or days.

While scrubbing isn't a complex process, there are nonetheless some areas of your home you might be neglecting. Here’s how to best approach a household scrub, as well as identify and disinfect some common germ hot spots.

1. Pay attention to high-touch surfaces and clean them frequently.

High-touch surfaces are exactly what they sound like: Areas in the home that get handled and touched regularly. Think doorknobs, light switches, appliance handles, toilet handles, faucets, and remotes. And don’t forget laptops, keyboards, desks, and phones.

2. Don't just do a quick wipe down. Get the entire surface.

Taking a disinfecting wipe to the keyhole of a doorknob isn’t going to do you much good—it's important to really scrub all high-touch surfaces. Make sure you get every available surface area, including the plate behind the knob where fingers and hands often brush against it. When cleaning remotes, make sure you don't just scrub the buttons, but the space between them as well.

3. You can use soap and water.

While products claiming to kill 99.9 percent of germs are best in this scenario, there's another option if you're having a hard time tracking down those supplies—simply mix some dish soap in water. It won’t kill organisms, but it can remove them from the surface. (And while soap and water can work for high-touch surfaces throughout the home, you shouldn't use the solution on electronics like your remote or keyboard.)

If you’re looking to kill germs, diluted bleach (four teaspoons to one quart of water) and 70 percent alcohol solutions work well. But it's important to note that bleach and other cleaners can harm certain surfaces. So be sure to do your research and make sure the product you're using won't cause any damage before you start scrubbing.

4. Take laundry precautions.

If you’re trying to be extra-vigilant about the spread of germs in the house, you should consider washing clothes at the highest possible temperature and disinfecting laundry bins. It’s also advisable to use disposable laundry bags.

5. Remove your shoes before entering the house.

This step is more preventative, but it’s a simple way to keep from tracking in contaminants. Remove your shoes before going inside and leave them near the door. It's also a good idea to clean floor surfaces with disinfecting mop cloths, but be sure anything you use is safe for the finished surface. Cleaners like bleach can discolor certain materials.

6. Don't forget to clean your car.

Even people vigilant about cleaning their home can neglect their car interior. Since you’re constantly touching virtually every surface, be sure to wipe everything down regularly, including the steering wheel and door handles. If you have a leather interior, there are auto wipes available for those surfaces. And before you go wipe down any touchscreens, be sure to check your owner’s manual to see if they require any special microfiber cloth.

7. Give your debit cards a wipe.

It’s a good idea to disinfect credit or debit cards that follow you around on shopping excursions. As with all high-touch objects, be sure to wipe them down every day.

The World Health Organization Is Releasing a COVID-19 App to Combat Coronavirus Misinformation

As is the case with most crises, the novel coronavirus has become a breeding ground for misinformation. Because the disease is so new, there are a lot of unanswered questions surrounding it, but that hasn't stopped people from claiming to know how to treat, prevent, and detect COVID-19. In an effort to separate fact from fiction, the World Health Organization (WHO) is launching an app dedicated to sharing what we know and don't know about the virus, 9to5Google reports.

Named WHO MyHealth, the new app is a collaboration between former Google and Microsoft employees, WHO advisors and ambassadors, and other tech and health experts. Users will be able to compare their symptoms with those linked to COVID-19 and receive public health updates specific to their location. As of now, there are plans to invite people who have been either been diagnosed with or exposed to COVID-19 to share their phone's location history to give experts a better idea of how the virus spreads.

WHO MyHealth, which is currently being built as open source, is set to roll out for Android and iOS on Monday, March 30. If you have questions about COVID-19 you need answered immediately, you can also access accurate and up-to-date information through the WHO's chatbot.

Any information regarding novel coronavirus should be met with skepticism when it can't be traced back to organizations like the WHO or the CDC—especially when it comes to supposed cures. No specific medication has been proven to treat or prevent COVID-19, so you shouldn't take advice from anyone claiming otherwise.
