MRI scans are strong diagnostics with high-definition images of what lies inside a body. Strong magnetic fields require precaution, as brought out by an instance where a young woman suffered very serious injuries due to an oversight in a metallic core within a silicone sex toy that she happened to have before the MRI scan. This makes a stark reminder about the potentially deadly consequences of missing metal objects when such procedures are being performed. In April 2023, a 23-year-old woman went into an MRI with a silicone plug containing a metal core that was not known.

She thought that the item is made entirely out of silicone according to the advertising. However, the strong magnetic field of the MRI machine interacted with the hidden metal, dragging the object through her body and causing excruciating pain. According to reports from the U.S. Food and Drug Administration (FDA), the scene was harrowing, with the woman screaming in agony and requiring immediate hospitalization. Despite pre-scan screenings, which are routine prior to a scan, the patient did not inform the facility that the object existed because he presumed it was purely non-metallic. This caused serious injuries that led to the patient's law suit against the manufacturer for deceitful misrepresentations of material content.

MRI machines employ magnets between 0.5 to 3 Tesla (T). This is thousands of times stronger than the Earth's magnetic field. The tremendous force causes ferromagnetic materials, like iron and nickel, to be magnetized quickly and become strongly attracted toward the magnet. Objects as small as hairpins or paper clips will accelerate at 40 miles per hour inside the magnetic field.

The force can lead to catastrophic injuries in items lodged within the body, such as metallic implants or foreign objects. Metallic cores within devices, like pacemakers or intrauterine devices, must be disclosed to radiologists to prevent such complications.

How Metal Objects Interact with MRI Fields?

On these claims, Dr. Adam Taylor, a specialist in human anatomy, weighed his words in a international health website and added that the distance away and mass of this object would increase its velocity towards that of sound, "The acceleration would be phenomenal, but with a metallic core, it can't go anywhere near supersonic speeds. As for the size, the magnetic acceleration to the internal soft tissues would ensure that there could be severe intracranial trauma."

The injuries inflicted in this case likely involved damage to major blood vessels, nerves, or organs, highlighting the devastating impact of even minor oversight during an MRI scan.

This is not an isolated case. There are documented cases of metallic objects causing serious damage during MRI scans with a 65-year-old man with schizophrenia swallowed metal objects, including sockets and a hinge pin. The powerful magnetic field during an MRI scan caused the objects to rupture his stomach, resulting in serious injuries.

A toddler who ingested 11 small magnets perforated his bowel while undergoing a scan, making his case unique. In another deadly but extremely rare incident, there have been people who hide a firearm on themselves during MRI procedures. Magnetic attraction can trigger a discharge in a weapon and has led to some fatal injuries.

These cases emphasize the very strong need for adequate screening and patient education prior to an MRI.

Preventing MRI-Related Incidents

Medical professionals have been trained to avoid risks. This is by properly screening a patient for metallic objects. In general, most pre-scan protocols include:

• Patients are interrogated about implants, recent surgery or exposures at work related to metals.
• Radiologists sometimes use handheld metal detectors to search for hidden items.
• People who work with metal, like welders or machinists, will need additional testing to detect microscopic metal fragments within soft tissues or eyes.

The case emphasizes the importance of product labeling by manufacturers, especially those products that are likely to unintentionally cause harm to health. The patient's assumption that her device was 100% silicone points to a larger problem in consumer markets with misinformation.

It also reminds the patients to report any possible dangers to the medical professionals, no matter how the objects look non-metallic. In sensitive cases, patients can request private discussions with healthcare providers to ensure safety without discomfort.

In the end, it is a joint effort from manufacturers, healthcare professionals, and patients that can prevent such tragedies. Manufacturers must ensure truthful marketing, while healthcare providers should educate patients about the dangers of metal objects in MRI settings. For patients, understanding the risks and actively participating in pre-scan disclosures can be lifesaving.

This young woman's experience is a sobering example of the unforeseen dangers posed by MRI machines when precautions are overlooked. It serves as a wake-up call to address gaps in patient awareness, medical protocols, and product transparency. By learning from this incident, the medical community and the public can work together to ensure MRI scans remain a safe and effective diagnostic tool.

Shigellosis, an intestinal infection caused by Shigella bacteria, is becoming harder to treat as drug-resistant strains spread in the US and UK.

Although the infection can spread through contaminated food and water, sexually transmitted Shigella has become an established part of transmission in some communities, particularly among gay, bisexual and other men who have sex with men (GBMSM).

An estimated 450,000 people acquire shigellosis each year in the US. While the infection can affect anyone, some strains have developed resistance to multiple antibiotics, making treatment increasingly challenging.

Drug-Resistant Shigella Rising In The US

A CDC analysis published in April 2026 found that extensively drug-resistant (XDR) Shigella isolates increased in the US between 2011 and 2023. Among 16,788 isolates analyzed, the proportion classified as XDR rose from 0% in 2011–2015 to 8.5% in 2023.

The CDC report found that 86.2% of XDR shigellosis patients with available sex data were men. However, sexual exposure information was not routinely collected, so the findings do not establish that these infections were sexually transmitted.

Molecular biologist Shangxin Yang said healthcare workers at the University of California, Los Angeles (UCLA), are now seeing roughly one case of extensively drug-resistant Shigella a month, compared with just one case throughout 2022.

"It's almost like an explosion of this pathogen in the community," Yang told CIDRAP News at the University of Minnesota.

The CDC has warned that XDR Shigella infections pose a treatment challenge because these strains are resistant to multiple antibiotics, and no FDA-approved oral antimicrobial treatment is available for them.

Sexually Transmitted Shigella Spreading Faster In The UK

A July study published in The Lancet Infectious Diseases found that sexually transmitted Shigella strains are spreading faster than non-sexually transmitted strains in the UK and developing resistance to key antibiotics.

Over an evolutionary period of about 2.5 years, sexually transmitted strains spread an average of 117 kilometers between related cases, compared with 46 kilometers for non-sexually transmitted strains.

“Many men who have sex with men are unaware of the serious and increasing risk posed by sexually transmitted Shigella,” said Professor Kate Baker, senior author of the study from the University of Cambridge's Department of Genetics.

Baker said sexually transmitted shigellosis should be treated as a distinct public health threat requiring different surveillance, prevention and treatment strategies.

Why Is Sexually Transmitted Shigella Becoming Drug-Resistant?

Cambridge researchers found that antibiotic-resistant sexually transmitted Shigella strains were spreading 71% faster than drug-susceptible strains. More than 70% of sexually transmitted strains were resistant to at least one clinically important antibiotic.

“This isn’t just one form of sexually transmissible diarrhea. This is multiple overlapping variants emerging that are all quickly becoming resistant to the drugs we use to treat them,” Baker said.

They believe the rise in resistance may partly be driven by antibiotics prescribed to treat or prevent other sexually transmitted infections (STIs), including gonorrhea.

“Our evidence suggests that the variants of Shigella transmitting in sexual networks were actually getting resistant against treatments for other STIs, like gonorrhoea, so people need to remember that when they’re taking antibiotics they’re treating their whole body,” Baker said.

Another possible factor is bystander resistance, in which antibiotic exposure affects bacteria other than the intended target and can favor the survival and spread of resistant bacteria.

How To Prevent Sexually Transmitted Shigella

Precautions to reduce the risk of sexually transmitted shigellosis include:

• Avoiding sexual activity during illness: Do not have sex while experiencing diarrhea or recovering from a recent diarrheal illness.
• Waiting before resuming sexual activity: Wait at least two weeks after fully recovering before having sex again.
• Telling your healthcare provider about possible exposure: Mention your sexual history if you seek care for diarrhea or related symptoms.
• Asking about testing: Seek advice on appropriate testing and sexual health screening if you may have been exposed.

People experiencing symptoms should seek medical advice. Because some Shigella strains are resistant to multiple antibiotics, treatment should be guided by a healthcare professional, who can determine the appropriate approach based on the infection and its resistance profile.

As the US measles outbreak nears 4,000 cases and five deaths amid concerns over vaccine hesitancy, the new CDC director Erica Schwartz says the MMR vaccine is “absolutely safe.”

The US has reported 3,887 confirmed measles cases in 2026, with 95% occurring among unvaccinated people or those with unknown vaccination status, according to CDC data as of October 1. The outbreak has also claimed five lives in Pennsylvania, all reportedly among unvaccinated people.

As of October 5, Pennsylvania has reported 1,004 measles cases, including 198 hospitalizations and five deaths. Lancaster County alone has recorded 391 cases. The outbreak is the worst recorded in the US since the major measles resurgence between 1989 and 1991.

This week, New York Governor Kathy Hochul declared a statewide disaster emergency after the state recorded 108 measles cases through October 3. Of these, 92 cases were reported since July 15 across 18 counties, particularly in under-immunized rural communities.

CDC Director Calls MMR Vaccine ‘Absolutely Safe’

“If there's one vaccine that parents should be talking to their health care providers about in terms of immunizing their children, the measles, mumps, rubella vaccine is absolutely safe, absolutely effective,” said Erica Schwartz, speaking at the WSJ’s Future of Health event.

“We want to make sure that we're constantly telling Americans that the MMR vaccine is safe.”

Measles is a highly infectious disease that can be prevented with vaccination. Two doses of the MMR vaccine are recommended for children, while some adults may also need additional doses depending on their vaccination history and risk.

Measles was considered eliminated in the US since 2000. However, the country could lose that status as cases continue to rise. The Pan American Health Organization is expected to decide in November whether the US has lost its elimination status.

The Trump administration and HHS Secretary Robert F. Kennedy Jr. have faced criticism over their anti-vaccine stance and policies amid the measles resurgence. More recently, President Donald Trump announced a proposal to separate the MMR vaccine into individual shots, which experts have warned could have consequences.

Meanwhile, Schwartz attributed the rise in measles infections across the US to declining herd immunity, saying, “the herd immunity within this country and other nations is lower than ever before.”

“And so because of that herd immunity, we really want it to be about 95%. I think we're hearing 87% in some communities, 98% in other communities. Because the herd immunity is lower, that's why we're seeing this resurgence of measles.”

Schwartz Says Vaccine Hesitancy Is A Global Issue

The recently appointed CDC director also noted that while the US is nearing 4,000 measles cases, there have been more than 45,000 cases of measles in Mexico and Guatemala. She attributed it to global rise in vaccine hesitancy.

“So it's not just a United States issue; it's an international issue. And I think the key critical issue is that there is vaccine hesitancy not just within the United States, but we're seeing that vaccine hesitancy throughout the world. Again, my premise is that all happened around COVID, where we were seeing folks who were just not trusting vaccines in general,” Schwartz said.

“We were finding that children were not getting vaccinated because they were not going to school during that time frame. So there's a number of reasons why we're seeing this increase in measles,” she said, adding that “people are conflating their concerns about all vaccines; all vaccines are bad.”

Schwartz also defended Health Secretary Robert F Kennedy Jr., and said he has always maintained that the MMR vaccine is safe and effective.

“I think what people get confused is that the secretary does represent the voices of a number of Americans who are asking the questions about certain vaccines. [...] And so there's this shared decision-making that the secretary is very focused on to say, why aren't we having conversations with parents, with people that may have some concerns about vaccines, rather than saying it's an all-or-nothing premise,” she said.

Plague is highly treatable if caught early, newly appointed CDC Director Erica Schwartz said, adding that the US is monitoring travelers arriving from Siberia following the reported death of a worker in Russia.

Speaking at the WSJ’s Future of Health event, Schwartz said the risk to the US from an unconfirmed case of pneumonic plague in Siberia was extremely low. She noted that the reported illness involved Yersinia pestis, the bacterium that causes plague.

“It’s a bacterial disease, a very serious bacterial disease. The one good thing is that it’s a treatable, highly treatable bacterial disease with common antibiotics that most physicians within the United States can utilize,” Schwartz said.

“This is a disease that is spread person to person through respiratory droplets, but as I said, if we can identify cases early, they’re absolutely treatable,” she added.

Schwartz said the CDC was prepared to monitor and screen travelers, particularly those arriving from Russia. She also discussed steps public health officials are taking to ensure Americans are protected from a potential threat linked to the reported case in Russia.

“There are about 200 flights that come into the United States from Siberia, that region. We are working with Department of Homeland Security, working (with) Department of State, Department of War, and other agencies within the government to make sure that we know exactly if anyone from that area comes into the United States,” Schwartz said.

She said flights from Siberia, where the plague-linked Irkutsk Anti-Plague Research Institute is located, typically arrive at JFK International Airport.

“We have a port health station set up in JFK so that we can do appropriate surveillance and screening if anyone from that area comes into the United States. So we’re very well positioned to make sure that we are protected from a potential threat like that,” Schwartz said.

An HHS spokesman said about 200 individuals per year from the Siberian region travel to the United States. Direct flights between Russia and the United States have been suspended since the start of the Ukraine war in 2022.

Russia Plague: What We Know So Far

Russia has reportedly seen two deaths allegedly linked to pneumonic plague. One was Darya Shipilova, a 28-year-old laboratory technician at the Irkutsk Anti-Plague Research Institute. The identity of the other person remains unknown.

Shipilova fell ill on September 29, was placed on a ventilator, and died on October 2. Around 200 contacts were reportedly placed under medical observation after she allegedly told doctors that she had accidentally broken a test tube containing live bacteria.

However, Russian authorities maintain that Shipilova died from “unidentified pneumonia”. Authorities said tests of her contacts found no dangerous infectious-disease pathogens, although some reportedly tested positive for COVID-19 or rhinovirus.

Russia has also denied reports of a second death linked to plague, calling them “fake news”.

In a statement published by Russian news agencies, the regulator denied what it called “fake information circulating on social media regarding a second case of illness”.

It said it had completed checks on all contacts of the dead woman, adding that “no health issues related to an infectious disease were detected” and that nearly 5,000 laboratory tests showed no dangerous pathogenic microorganisms, Reuters reported.

US President Donald Trump and Senator Rand Paul have publicly criticized Russia’s handling of the situation, with Trump calling it a “big problem for Russia” and Paul accusing Russia of not fully cooperating with international health authorities.
