Singer Jesy Nelson recently shared an emotional update regarding the complications she is experiencing in her pregnancy with twin babies. Former Little Mix singer Jesy, who is having twins with partner Zion Foster, announced that she has been diagnosed with pre-twin-to-twin transfusion syndrome (pre-TTTS). The condition, which is present in pregnancies involving twins with a shared placenta, has serious risks involved and needs intense medical supervision. As Nelson embarks on this difficult journey, her story enlightens us about a rare but dangerous condition many expectant parents may not know much about.

Twin-to-twin transfusion syndrome is a rare but dangerous condition that arises in monochorionic twin pregnancies, in which identical twins share a single placenta. The placenta supplies the developing babies with oxygen, nutrients, and blood flow, but in TTTS, there is an imbalance of blood vessels that interconnect the twins, and thus the vital resources are not evenly distributed. One twin, or the donor twin, shares excess blood with the other, referred to as the recipient twin. This leads to one baby becoming malnourished and possibly anemic, and the other in danger of heart problems due to too much blood.

Nelson described her diagnosis in a heartfelt Instagram video, explaining that she is currently in the pre-stage of TTTS and undergoing frequent monitoring. "I am being scanned twice a week, and each time, things have gotten a little worse," she shared, expressing her fears and hopes for the health of her babies.

Potential Risks of TTTS

If left untreated, TTTS can have devastating consequences. Medical research indicates that:

• 90% of the cases of untreated TTTS lead to loss of one or both twins.
• Despite treatment, only a 70% survival rate for both twins is assured.
• Severe forms can result in preterm labor, cardiac failure in the recipient twin, and organ failure in the donor twin.
• Complications in long-term survivors include neurological damage and developmental delay in surviving infants.

TTTS usually advances in stages, beginning with minimal changes in fluid levels and worsening as one twin continues to get an unequal share of blood. In extreme cases, fetal laser surgery, referred to as the Solomon technique, can be employed to divide the blood vessels and balance the twins.

Why Identical Twin Pregnancies Are More Complicated

Identical twins may develop differently, and their own unique form of placental sharing can have a dramatic effect on pregnancy risk. Jesy Nelson's twins are considered monochorionic diamniotic (mono/di), which means they share a placenta but have two amniotic sacs. This is the type of pregnancy in about 70% of identical twin pregnancies and carries an increased risk of complications like TTTS, umbilical cord entanglement, and growth restriction.

Conversely, dichorionic diamniotic (di/di) twins both have a separate placenta and amniotic sac, which greatly diminishes the threat of TTTS. Twin pregnancy type is normally identified by early ultrasound, with physicians being able to track future complications from inception.

Other Twin Pregnancy Health Risks

Twin pregnancies, even without the presence of TTTS, entail a variety of health risks to the mother as well as infants:

1. Premature Birth

Over 60% of twin pregnancies end in premature delivery, with birth usually taking place before 37 weeks. Premature infants can have immature organs and need neonatal intensive care (NICU) assistance to assist with breathing, feeding, and infection fighting.

2. Gestational Hypertension and Preeclampsia

Pregnant women with multiples are at increased risk of having high blood pressure during pregnancy. This, if left untreated, can result in preeclampsia, a serious complication of pregnancy that can result in damage to organs, preterm labor, and in some cases, maternal or fetal death.

3. Anemia

Pregnant women carrying multiples are twice as likely to experience anemia, a condition where the body does not produce enough healthy red blood cells. This can lead to fatigue, dizziness, and complications during delivery.

4. Birth Defects

According to John Hopkins Medicine, multiple birth babies are twice as likely to have congenital abnormalities compared to single births. These can include heart defects, neural tube defects, and gastrointestinal issues.

5. Amniotic Fluid Imbalances

When twins have to share a placenta, they are more likely to have polyhydramnios (excess amniotic fluid) or oligohydramnios (not enough amniotic fluid). Both result in distress to the babies during fetal development and can result in premature labor.

6. Postpartum Hemorrhage

Twins are at increased risk of excessive postpartum hemorrhage because their uterus is larger and there are greater blood supply needs.

Jesy Nelson's openness about her challenging experience is raising awareness for TTTS, a condition that few individuals—let alone expectant mothers and fathers—might be aware of. Through her tearful video, Nelson stressed the significance of knowing about twin pregnancies aside from the thrill of having multiples. "We had no idea that this type of thing occurs when you're having twins. We just desperately want to make people aware of this because there are so many people who aren't aware."

Her case reminds us of the intricacies involved in twin pregnancy and the significance of early identification and medical management. For mothers carrying twins, frequent ultrasounds and vigilance can become a life-and-death issue for early detection and better outcomes of both babies.

Through constant medical attention and care, she and her partner Zion Foster remain positive and get ready for their babies to be born. In other parents whose situations are no different, the story of Nelson highlights awareness, medical progress, and emotional encouragement in handling complicated pregnancies.

The expecting parents of twin siblings are advised to discuss TTTS screening and possible interventions with their physicians to give their babies the best chance.

The much-awaited 2026 FIFA World Cup is set to begin tonight. The tournament will be hosted by the United States, Canada, and Mexico across 16 cities in the three countries.

The 39-day event kicks off in Mexico on Thursday amid ongoing health outbreaks such as measles, Ebola, and hantavirus.

More than 750,000 soccer fans are expected to travel from over 100 countries to witness 104 matches. The influx of visitors will crowd public transportation, restaurants, and other public spaces, increasing the risk of exposure to infectious diseases, heat-related illnesses, and injuries.

FIFA World Cup: US Experts To Monitor Wastewater

A public health team based in Washington, D.C., plans to monitor wastewater and internet activity to detect and track infectious diseases should they emerge in any of the US or Canadian cities hosting World Cup matches, players, and millions of spectators, Reuters reported.

Detecting disease-causing microorganisms in wastewater can provide an early warning of emerging outbreaks, giving health officials time to alert clinicians to watch for symptoms that might otherwise be misdiagnosed and to encourage the public to take preventive measures.

Beyond infectious diseases, heat is expected to be a major concern during the FIFA World Cup. Host cities such as Houston, Miami, Mexico City and Los Angeles can experience extreme temperatures in June and July, making it dangerous for fans standing outdoors in large crowds for extended periods.

Writing in Forbes, Jesse Pines, an integrative medicine physician at Eterna Integrative and a Clinical Professor at George Washington University (GW), explained that heat exhaustion occurs when the body overheats and loses vital fluids and salts through sweating.

"Warning signs include dizziness, a rapid but weak pulse and cool, clammy skin. Left untreated, it can escalate quickly into heat stroke — a life-threatening emergency that can kill or cause permanent brain damage. Core body temperature above 104 degrees F, confusion and cessation of sweating are the hallmarks," he said.

Pines noted that alcohol can significantly increase the risk of heat-related illness. To reduce the risk, he recommends eating a full meal before drinking, choosing water over alcoholic beverages and keeping electrolyte drinks on hand.

Who Is Most at Risk?

The expert said certain groups may face a higher risk during mass gatherings in summer heat, including:

• People aged 65 and older
• Individuals with chronic conditions such as heart disease, diabetes, COPD or kidney disease
• People who are immunocompromised
• Pregnant fans

The UK government has confirmed a case of hantavirus infection in Tristan da Cunha, a remote British Overseas Territory in the South Atlantic Ocean, World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus has said.

In a post on social media platform X, Tedros said the patient had previously been classified as a probable case and had been exposed aboard the MV Hondius.

“As of June 10, the total number of confirmed cases remains 13, including three deaths,” he said. “No new deaths have been reported since May 2,” when a cluster of severe respiratory illnesses linked to the Dutch-flagged cruise ship MV Hondius was reported to the WHO.

While the outbreak aboard the luxury vessel had raised concerns about wider transmission. However, the WHO has assessed the overall risk to the public as low. The global health body recommended active health monitoring for all evacuated passengers for 42 days from their last exposure date, either in designated quarantine facilities or at home. The monitoring period is scheduled to continue until June 21.

The outbreak, which claimed three lives and infected 13 people, was driven by the Andes strain, which carries a risk of human-to-human transmission. There is currently no specific antiviral drug or vaccine for the Andes virus.

Study Suggests Potential Treatment

A recent study published in The Lancet Infectious Diseases reported early promising results for tocilizumab as a treatment for severe hantavirus pulmonary syndrome (HPS).

The study is based on a case series involving 10 hantavirus patients treated at Hospital Zonal de Bariloche, Argentina, between June 1, 2024, and May 6, 2026.

Tocilizumab is an immunosuppressive medication used to treat severe inflammatory conditions, including severe COVID-19 and autoimmune diseases such as rheumatoid arthritis.

Researchers from San Carlos de Bariloche, Argentina, said that under an ethical framework allowing the emergency use of unproven medications outside clinical trials when no satisfactory alternatives exist, tocilizumab was administered to five eligible patients with laboratory-confirmed severe hantavirus pulmonary syndrome.

Five other patients received standard supportive care without tocilizumab because they were too sick or the medication was unavailable when treatment was being considered. The researchers said tocilizumab warrants further evaluation as a treatment for severe hantavirus pulmonary syndrome.

What Is Hantavirus?

According to the WHO, hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans.

Globally, an estimated 100,000 to 200,000 hantavirus infections occur each year. The majority of these cases are in Asia, particularly China. Most are sporadic or occur in small clusters linked to contact with infected rodents.

Infection in people can result in severe illness and often death, although the diseases vary by type of virus and geographical location.

The WHO has confirmed that the Andes strain of hantavirus—the only strain known to spread from person to person—is responsible for the outbreak. There is currently no vaccine available for the strain.

Notably, the WHO has not specified the type of hantavirus or syndrome involved in the cruise ship incident, but it did mention respiratory risks.

How Does Hantavirus Spread?

Hantavirus is primarily spread by rodents through:

• Exposure to rodent urine
• Exposure to rodent droppings
• Exposure to rodent saliva
• Less commonly, through a rodent scratch or bite.

Two orphaned babies have died of Ebola in the Democratic Republic of Congo, in an outbreak that could rival the worst on record.

Baby Buswaza was brought to a church-run orphanage in eastern Congo after her mother died in late May. The newborn was running a fever and, within days, died from what was later found to be Ebola, Reuters reported.

Buswaza was buried in late May in a sealed, waterproof body bag to prevent the spread of the disease.

More Suspected Cases at Orphanage

Six more babies have been identified as suspected Ebola cases at the orphanage of 69 children in Bunia, a city in Ituri province at the epicentre of the outbreak in Congo.

They were taken to hospital, where five of them later tested negative and were discharged from an isolation tent at the Evangelical Medical Centre (CME) by medics.

Another baby—an orphaned triplet girl nicknamed "Cherie" or "darling" who was less than a year old—with confirmed Ebola died on June 10, Dr. Freddy Kibwana, head of the CME, told Reuters. "The child has left us," he said.

How Children Can Be at Risk of Ebola

Children and babies can easily become vectors for the disease through bodily fluids like vomit, faeces and saliva, which are highly infectious when people have Ebola.

"This epidemic has hit an area already in humanitarian crisis," said Babou Rukengeza, a senior health adviser with Save the Children aid group. "This place is the only refuge for these children."

“This outbreak is moving at a terrifying speed. I have responded to several Ebola outbreaks over the years, but this is the fastest spread I have ever seen. Children are paying a devastating price," he added.

The expert noted that “when parents die, children suddenly lose the biggest support system they could possibly have and face fear, grief, stigma, and social exclusion".

Can Ebola Be Passed From Mother to Child?

In addition to fluids like blood and saliva, Ebola has also been detected in amniotic fluid and the placenta, as per the World Health Organization, so it is possible Buswaza's mother transmitted the virus to her in the womb or during childbirth.

If the mother caught the virus after giving birth, she may also have transmitted it to her child through breastmilk, where the virus has also been detected.

Ebola Cases And Death Toll Climb

According to the US CDC, the confirmed cases in Congo have risen to 635, while there are 127 confirmed deaths. In Uganda, there are 19 confirmed cases and two confirmed deaths, along with one probable case and one probable death.

Using genetic fingerprinting, the illnesses have been identified as Bundibugyo virus, one of the four types of orthoebolaviruses that cause Ebola disease in people. There is no vaccine for Bundibugyo virus, and treatment consists of supportive care.

Ebola Outbreak: WHO Raises Risk Assessment

Meanwhile, the WHO has revised the risk assessment in Congo and Uganda. The risk has been revised to “very high at the national level in DRC and high for Uganda,” the WHO said.

It is also high for countries sharing land borders with DRC and Uganda, while low for the rest of the Africa region and at the global level.

The WHO explained that the risk in DRC remains very high because “the outbreak has continued to expand rapidly in terms of numbers of cases and geographical spread with more areas affected. Epidemiological links and the full chain of transmission are not yet clearly established, and the source of the outbreak remains under investigation”.

Moreover, the ongoing conflict is restricting movement of frontline responders and surveillance teams, while community fear and misinformation are hindering case detection, contact tracing and isolation, and potentially facilitating disease spread.

There are also other challenges such as limited healthcare infrastructure and delays in laboratory confirmation, although these are being scaled up by DRC with support from partners, the WHO said.
