In a landmark move to strengthen global preparedness and response to mosquito-borne illnesses, the World Health Organization (WHO) has released its first-ever integrated clinical guidelines for the management of arboviral diseases. These include some of the most common and dangerous viruses transmitted by mosquitoes — dengue, chikungunya, Zika, and yellow fever.

The guidelines, published earlier this month, aim to provide frontline healthcare workers, hospitals, and policymakers with evidence-based, standardized protocols to treat both mild and severe cases. With arboviral diseases rapidly expanding in reach and impact, particularly in tropical and subtropical regions, WHO hopes these clinical tools will help reduce mortality and morbidity rates.

What Are Arboviral Diseases?

Arboviral diseases are viral infections transmitted by arthropods, mainly mosquitoes — especially the Aedes aegypti species. This single vector can carry and transmit multiple viruses at once, which makes controlling outbreaks even more challenging.

According to WHO, over 5.6 billion people — more than half of the global population — are at risk of contracting arboviral infections. These diseases often start with non-specific, flu-like symptoms such as fever, rash, and joint pain, making accurate diagnosis difficult without laboratory confirmation. However, they can lead to severe complications, including hemorrhage, neurological damage, or organ failure, if left untreated or mismanaged.

Why the Guidelines Are Critical Now

In a statement, WHO underscored the urgency of a unified global response, citing increasing frequency and severity of arbovirus outbreaks, driven by climate change, urbanization, global travel, and weakened public health systems.

“Outbreaks of arboviral diseases are becoming more frequent, widespread, and severe,” said the WHO. “The new clinical guidelines aim to help health workers distinguish between these infections, which often have overlapping symptoms, and manage cases more effectively even when diagnostic tools are scarce.”

In many endemic regions, multiple arboviruses circulate simultaneously, further complicating diagnosis and treatment. This is where the integrated approach — which applies common principles of care across different arboviral diseases — can help streamline responses during outbreaks.

Key Recommendations from WHO

The new WHO guidelines cover clinical care protocols for both non-severe and severe forms of dengue, chikungunya, Zika, and yellow fever. The recommendations are tailored to help practitioners manage symptoms, avoid harmful treatments, and recognize complications early.

For Non-Severe Cases:

• Use oral fluids to prevent dehydration.
• Treat pain and fever with paracetamol or metamizole.
• Avoid NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen.
• Avoid corticosteroids unless symptoms worsen.

For Severe Hospitalized Cases:

• Use crystalloid fluids (not colloids) for IV hydration.
• Monitor capillary refill time and lactate levels to guide fluid resuscitation.
• Apply passive leg raise test to assess shock and fluid responsiveness.
• Avoid corticosteroids and immunoglobulin therapies.
• Do not transfuse platelets unless there is active bleeding, even in patients with low platelet counts.
• In yellow fever-related liver failure, administer intravenous N-acetylcysteine.
• Use experimental drugs like TY014 (monoclonal antibodies) and sofosbuvir for yellow fever only in research settings.

A Step Toward Global Health Security

These new protocols are built on the latest clinical and scientific evidence, and WHO confirmed that they will be updated as new research becomes available. By standardizing treatment across countries, the guidelines are expected to improve patient outcomes and prepare health systems to tackle emerging threats.

As arboviral infections continue to grow in complexity and reach, experts say that timely, consistent, and data-driven care can mean the difference between recovery and tragedy — especially in resource-limited settings.

WHO’s unified approach offers a roadmap for healthcare workers worldwide to navigate the rising tide of mosquito-borne illnesses — and better protect the billions at risk.

A 57-year-old schoolteacher from Kolkata, Ruma Sen* had spent decades standing in front of classrooms, guiding young minds with poise and patience. But when her own body began to send quiet warnings—persistent bloating, fatigue that lingered, clothes fitting tighter than usual—she brushed it off. “I just assumed it was something I ate or part of aging,” she recalls. Yet, deep down, a quiet concern stirred. And then came the ultrasound that changed everything.

A mass on her left ovary. Fluid accumulating in her abdomen. The CT scan and biopsy confirmed what no one wants to hear: Stage IV high-grade serous ovarian cancer, with metastases to her intestines and abdominal lining.

“I felt like the floor had vanished beneath my feet,” Ruma says. “In that moment, the future I imagined just disappeared.”

“Ovarian cancer often whispers until it roars,” explained Dr. Debapriya Mondal, Ruma’s medical oncologist at Apollo Cancer Centre, Kolkata. “By the time it's diagnosed, it's usually advanced. But even Stage IV isn't without hope.”

This late-stage diagnosis is common with ovarian cancer, especially its most aggressive subtype—high-grade serous carcinoma. It lacks early symptoms that are easily distinguishable from benign issues like indigestion or menstrual irregularities. That’s why it’s dubbed the “silent killer.”

Round One: Chemotherapy as the First Line of Defense

Chemotherapy began within days of diagnosis. The plan was clear: shrink the tumors to make surgery safer and more effective. The process, however, was anything but clinical for Ruma.

“The first cycle made me violently nauseous. My hair fell out in clumps. I was too weak to stand some mornings,” she remembers. Despite the toll, the treatment was working. By the third cycle, imaging showed significant tumor shrinkage.

“Chemotherapy is brutal,” Dr. Mondal admits. “But when the scans show tumors shrinking, it’s our signal that we’re fighting back—and winning ground.”

Round Two: A Critical Turning Point Surgery

Ruma’s next hurdle was interval debulking surgery, a complex procedure to remove all visible tumors, followed by HIPEC (Hyperthermic Intraperitoneal Chemotherapy)—a method where heated chemotherapy is delivered directly into the abdominal cavity during surgery.

“It was the toughest part,” Ruma says. “I woke up in ICU with tubes everywhere. My abdomen felt like it was on fire.” Recovery was grueling. Ten days in the hospital marked by small but vital victories: sipping water, standing unaided, breathing without assistance.

“HIPEC is not for every patient,” Dr. Mondal says. “But in selected cases like Ruma’s, it increases the chances of a long remission or even a cure.”

Round Three: Genetic Testing and Personalized Medicine

As Ruma regained strength, her care team ordered homologous recombination deficiency (HRD) testing, a genomic analysis that helps determine how well a tumor repairs its DNA. The results revealed a germline BRCA1 mutation, a known genetic driver of ovarian cancer.

“This changed everything,” Dr. Mondal explains. “When tumors carry this mutation, we can use targeted maintenance therapy, such as PARP inhibitors, which drastically reduce the risk of recurrence.”

For Ruma, the discovery was both empowering and alarming. “I now had a new weapon against my cancer. But I also worried about what it meant for my daughters.”

She completed three more cycles of chemotherapy and transitioned to oral PARP inhibitors—medications designed to exploit her cancer’s genetic vulnerabilities. For the next two years, she remained under strict oncologic surveillance, with regular scans and bloodwork to track any signs of recurrence.

Ruma’s diagnosis didn’t just change her life—it changed her family’s trajectory.

Her two daughters, Megha** and Ananya**, underwent genetic counseling and testing. Megha, the elder at 35, tested positive for the same BRCA1 mutation. “It was a gut punch,” Megha says. “But I felt lucky to know.”

After consulting with specialists, she opted for risk-reducing salpingo-oophorectomy (RRSO)—a preventive surgery to remove her ovaries and fallopian tubes. “It meant early menopause. But it also meant I was taking control of my future,” Megha explains.

According to Dr. Mondal, this kind of cascade testing—where family members of patients with genetic mutations are screened—is vital. “We now have tools not just to treat cancer, but to prevent it. Megha’s decision may have significantly lowered her lifetime risk of ovarian and breast cancer.”

Today, Ruma is in clinical remission. She has resumed teaching, started leading yoga sessions for cancer survivors, and advocates for genetic testing and early detection. “I used to fear my body,” she admits. “Now I listen to it. I take care of it.”

She also speaks publicly about her cancer journey, helping dismantle the stigma and fear surrounding a disease that affects nearly 300,000 women worldwide each year, according to the World Health Organization.

“We are in a new era of precision oncology,” Dr. Mondal emphasizes. “We are no longer limited to one-size-fits-all treatments. Every tumor has a story written in its DNA—and we’re learning how to read it.”

Why It Is Important To Listen to Your Body?

Ruma’s story is more than a personal victory. It’s a real-world example of how modern oncology is evolving—from late diagnosis to targeted intervention, from suffering in silence to survivorship with purpose. Here’s what it tells us:

• Listen to your body, even when the symptoms seem minor.
• Early diagnosis remains rare, but genetic insights can improve long-term outcomes.
• Precision medicine—like HRD testing and PARP inhibitors—is rewriting how we approach advanced cancer.
• Genetic counseling empowers entire families, not just patients.
• And most importantly, survival is possible, even in Stage IV.

“I don’t know what the future holds,” Ruma says. “But I know I’ve done everything in my power to live it fully.”

A team of researchers at the University of South Australia (UniSA) has developed a weekly injectable drug that could significantly improve the lives of people living with Parkinson’s disease. The new treatment, which offers a steady release of key medications over seven days, may eliminate the need for multiple daily pills — a major breakthrough for both patients and caregivers.

Consistent Dosing, Less Burden

The injectable has been designed to maintain consistent levels of levodopa and carbidopa — two medications that form the cornerstone of Parkinson’s treatment. These drugs typically need to be taken multiple times a day to manage symptoms effectively. However, this frequent dosing can be challenging for patients, especially older adults or those who have difficulty swallowing pills.

“This new formulation is about simplifying care,” said Professor Sanjay Garg, lead researcher from UniSA’s Center for Pharmaceutical Innovation. “Our goal was to create a treatment that ensures consistent drug levels in the body, reduces dosing frequency, and makes life easier for patients.”

According to the study, published in the journal Drug Delivery and Translational Research, the weekly injection uses biodegradable polymers to deliver the medications slowly and steadily into the body. The formulation can be injected under the skin or into the muscle using a fine needle — avoiding the need for surgery or implants.

Promising Lab Results

In lab tests, the injection successfully released over 90% of levodopa and 81% of carbidopa within a seven-day period. Importantly, the biodegradable implant degraded by more than 80% during that time and showed no significant toxicity in safety evaluations.

“We're not just improving how the drug is delivered — we're improving patients’ lives,” Professor Garg said. “This could be a game-changer for people with Parkinson’s who struggle with the current complex medication schedules.”

The researchers also noted that this delivery platform could be adapted to treat other chronic diseases such as diabetes and cancer. Plans for clinical trials and commercial development are already underway.

Understanding Parkinson’s Disease

Parkinson’s disease is a progressive neurological disorder that affects movement and coordination. It occurs when nerve cells in the brain that produce dopamine — a chemical messenger that controls movement — begin to die.

Common symptoms include:

• Tremors or shaking
• Muscle stiffness
• Slowed movement
• Balance and coordination issues

Difficulty walking or talking in advanced stages

There is currently no cure for Parkinson’s, but medications like levodopa help manage the symptoms by replenishing dopamine levels in the brain. However, the effects of these medications can wear off quickly, requiring frequent dosing throughout the day.

According to the World Health Organization, more than 8.5 million people worldwide are living with Parkinson’s disease — a number that has doubled in the past 25 years. The disease also carries a significant economic burden due to ongoing medical care, medications, and caregiving needs.

A 2020 study published in The Lancet Neurology noted that the global cost of Parkinson’s could reach over $79 billion annually by 2030 if no major advancements in treatment are made.

Menopause brings big changes to a woman's body, however, many do not know how these changes affect their health. A Jan study published in the Circulation Research showed that when a woman goes through menopause could tell us a lot about her future heart health. A study published recently found that women who stopped having periods later in life generally had healthier blood vessels. They were also much less likely to suffer heart attacks and strokes after menopause, compared to those who went through it earlier.

Menopause And Heart Health

The researchers also noted that these women who had later menopause had better fat levels in their blood and fewer signs of "oxidative stress". This might help explain why their hearts seemed healthier.

Most women enter menopause between ages 45 and 55, with the average in the U.S. being 52. However, about 10% of women experience "late-onset" menopause, meaning it starts after age 55.

Late Menopause and Your Heart Disease Risk

For this study, researchers looked at 21 women who were still having periods and 71 women who had already gone through menopause. The postmenopausal group was then split based on whether their menopause started at a normal age or later.

To check their heart and blood vessel health, the researchers measured how well a main artery in the arm could widen. They also looked at the health of the mitochondria inside blood vessel cells, and checked levels of hormones, fats, and other substances in the blood.

As expected, all women who had gone through menopause had less healthy blood vessels compared to those still having periods. This is normal as estrogen levels drop and blood vessels tend to stiffen with age. Also, as we get older, these "power plants" in our cells can produce more harmful molecules called free radicals, leading to something called oxidative stress, which can cause diseases like heart disease.

However, the surprising finding was that women in the late-onset menopause group seemed to be somewhat protected from this age-related decline in blood vessel health.

Their blood vessel function was only 24% worse than the premenopausal group, while for those with normal-onset menopause, it was 51% worse. This better blood vessel function lasted for at least five years after menopause for the late-onset group. Women in the late-onset group also had better functioning "power plants" (meaning fewer harmful free radicals and less oxidative stress) and healthier fat levels in their blood.

Why Menopause Impacts Heart Health

Even though women with later menopause had relatively better heart health in the study, it's important to remember that all women face a higher risk of heart disease once they go through menopause.

Studies show that this is largely due to estrogen. According to the Oxidative medicine and cellular longevity journal, estrogen is known to protect against heart disease. Once a woman's estrogen levels drop during menopause, she starts to lose that protective effect. As a result, many women will see their blood pressure and cholesterol levels go up, even if their diet and activity levels don't change.

So, it makes sense that women who go through menopause later have better heart health. The longer your body produces estrogen, the more protection your heart gets. Blood vessels work better before menopause, meaning they are more resistant to damage and heart attacks the longer you stay out of menopause.

Protecting Your Heart During and After Menopause

While you usually can't control when you start menopause, you can still take steps to protect and maintain your heart health during and after this transition. This includes following the usual advice for a healthy lifestyle:

• Starting a healthy diet with more fruits and vegetables, and less meat and cheese.
• Monitor your cholesterol levels.
• Staying active is crucial, aim for at least 30 minutes of exercise most days of the week, including both cardio and strength training
• Getting enough sleep is also vital for heart health; however, this can be tough during menopause due to issues like insomnia and night sweats.
