Many diseases share the same symptoms, causing people to get confused and either undermine or overwhelm themselves with worries. With the current flu season on the rise, people in the United States are being very careful about their health and are taking necessary precautions to make sure they do not catch any more respiratory illnesses. Often these diseases show symptoms like coughing and wheezing, nothing that warrants anything more than a general doctor’s visit, sometimes people even think it it is a simple cold, but it could be something worse!

The Centers For Disease Control and Prevention (CDC) report on 28 February, last Friday on Respiratory Virus Activity Levels reported a moderate number of people are seeking medical help for respiratory illnesses. The flu is sending many people to the emergency room, RSV Respiratory syncytial virus has been sending many people to the ER along with COVID-19.

While flu test results are slightly less positive than last week, COVID-19 and RSV test results are about the same. In our community's wastewater, the flu virus is still very high, COVID-19 is moderate, and RSV is low. Looking forward, we expect COVID-19 emergency room visits to stay low. While flu visits are still high, they should start to go down soon.

So, even though it might feel like winter is ending, these viruses are still active, and we need to be careful. They are not going away quickly and can still spread easily. Here are some symptoms that should be treated with urgency right now.

Severe Dehydration

When you're really sick, you might not feel like eating or drinking. This can lead to dehydration, which is when your body doesn't have enough water. If your pee is dark yellow, or you feel dizzy, you might be dehydrated. If you pass out, get confused, or your heart beats really fast, you need to go to the hospital right away. Healthcare professionals can give you fluids through a needle to help you feel better. Being dehydrated is very dangerous, and it is important to take it seriously.

Breathing Difficulties

If you're having trouble breathing, or if you're breathing really fast, that's a big sign. It could mean that you have pneumonia or that your body isn't getting enough oxygen. Shortness of breath is always a reason to go to the emergency room. Your body is telling you that something is seriously wrong. It is very important to seek help right away. Do not wait it out at home.

Low Oxygen Levels

If your lips or fingers start to turn blue, that means you're not getting enough oxygen. Also, if you're so tired that you can barely get out of bed, that's another sign that you need to go to the hospital. These are serious symptoms that mean your body needs help right away.

Who’s Most at Risk for Severe Symptoms?

Some people are more likely to get very sick from these viruses. Pregnant people, little kids, and older adults are at higher risk. Also, people who have health problems like heart or lung disease, or people with weak immune systems, are more likely to have serious problems. Older adults are often hospitalized with the flu, COVID, and RSV. These groups need to be extra careful to avoid getting sick. It is very important that these groups get vaccinated.

RSV is especially dangerous for babies and young children. It's one of the main reasons why young kids end up in the hospital. This virus can make it very hard for them to breathe. It is very important to protect young children from this virus, especially in the first few years of their lives.

In a shocking case highlighting delayed diagnosis, a UK-based man visited doctors 24 times in a year for persistent back and leg pain but was repeatedly dismissed. He died just 12 days after being diagnosed with cancer.

The symptoms of 61-year-old Nigel began with lower back and leg pain. As the cancer spread across his body, he suffered from indigestion and severe weight loss. His doctors ignored his symptoms and could not even pinpoint the exact cancer till his death.

It was only a week after his death that the doctors were able to find that Nigel had pancreatic cancer — a type of cancer that often goes undiagnosed due to a lack of early detection tests, said his wife, Liv Williams, writing in an essay for Metro.co.uk.

“Nigel saw a healthcare professional 24 times, and even then, we didn't know it was pancreatic cancer. If something like the breath test had been available, maybe Nigel could have had treatment to give him more time with us,” Liv explained.

Nigel, a father of three, began experiencing lower back and leg pain in early 2023. Liv said that his primary care doctor referred him to a physiotherapist, but the wait took months and his condition worsened. He also developed serious indigestion.

“From March to June, Nigel sought medical advice, and each time he was sent away, either empty-handed or with medication for pain or indigestion,” she said.

Thinking the pain must be related to a spinal issue, the family paid out-of-pocket for an MRI. The lumbar spine MRI scan revealed nothing.

"But what is it then?, we asked in frustration numerous times; always to be told it would get better on its own," Liv wrote in the essay.

By July, Nigel could not stand the pain, and Liv was forced to take him to the Emergency Room (ER).

“His painful leg was getting thinner and thinner, like it was wasting away, and the pain was unbearable,” she said. Nigel lost significant weight, struggled to eat, relied on crutches, and could not sleep due to constant pain.

“Just before Christmas, I demanded a blood test from his GP – but three weeks later, a few days before the scheduled tests, Nigel couldn't urinate, which left him in agony,” she added. A visit to the ER was unfruitful as they had to rush back due to his pain.

The next time they visited the hospital, Nigel "screamed with pain", and seeing this, "a nurse promptly set him up on a bed with an IV".

The next day, the doctors informed Liv that Nigel had cancer. But as it had metastasized so much that his doctors could not pinpoint the exact cancer.

In just 12 days on February 9, 2024, Nigel died surrounded by his family.

What Is Pancreatic Cancer? Know The Warning Signs

Pancreatic cancer has long been one of the toughest challenges in oncology. With a five-year survival rate hovering around 13 percent and recurrence rates approaching 80 percent after treatment, the odds have historically been stacked against patients.

The prevention and early detection remain vital.

Experts warn that pancreatic cancer often masquerades as common ailments, delaying diagnosis. Here are some early symptoms that should never be ignored:

• Abdominal or back pain that worsens over time or eases when leaning forward.
• Unexplained weight loss without changes in diet or exercise.
• Jaundice, including yellowing of the eyes and skin, sometimes with intense itching.
• Changes to urine or stool, such as dark urine or pale, greasy stools.
• New-onset diabetes without obvious risk factors.
• Persistent fatigue unrelated to poor sleep or lifestyle

Kidneys are extraordinary organs that perform critical tasks on a continual basis, e.g., filtering out waste, keeping electrolytes balanced, controlling blood pressure, and providing metabolic stability.

However, many people don’t pay enough attention to keeping their kidneys healthy until they discover that substantial damage has already happened.

Some of the most prevalent and underestimated threats to kidney functioning include uncontrolled blood pressure, chronic anxiety, and unhealthy living.

The Effect Of Hypertension On Kidney Function

Hypertension (high blood pressure) is considered one of the most prevalent causes of CKD (chronic kidney disease) worldwide.

The kidneys need the support of a complicated design of tiny blood vessels to carry out their task of removing waste from the bloodstream. An ongoing and increased blood pressure level will slowly harm these small blood vessels by reducing their ability to function normally. As time passes, this injury will result in scar formation of the kidney tissue, causing a continual decline in the kidney’s ability to filter.

Hypertension is known as a silent killer because it frequently has no symptoms for many years. By the time someone experiences symptoms of high blood pressure, their kidneys may have already been damaged for a considerable period.

Chronic stress is often overlooked as an indirect cause of kidney damage. When we are under chronic stress, our sympathetic nervous system is activated, and the amount of stress hormones (cortisol and adrenaline) in our bodies increases.

These physiological changes lead to prolonged increases in blood pressure and blood glucose; both of these risk factors are bad for our kidneys. Chronic stress may cause people to engage in unhealthy coping strategies like poor diet, smoking, consuming alcohol, or not being physically active, which also increases their risk of kidney damage.

Our long-term kidney function is largely determined by lifestyle choices, including our dietary habits. Diets high in sodium, processed foods, and unhealthy fats increase the probability that you will develop hypertension, metabolic disorders, or some combination of both of these, which puts even more strain on your kidneys.

The sedentary lifestyle associated with obesity, insulin resistance, and cardiovascular disease are all significant contributors to chronic kidney disease. Dehydration, taking large amounts of over-the-counter medications (especially NSAIDs), and using tobacco products are all additional risk factors for progressive loss of kidney function.

Preventative Interventions For Kidney Health

Many of these risk factors can be addressed through prevention.

Regular monitoring of blood pressure, using mindfulness and other methods to manage stress levels, and maintaining a healthy diet full of fruits, vegetables, and whole grains will all help to reduce the strain on your kidneys.

Regular health screenings for people who have some of the above-mentioned risk factors (e.g., diabetes, high blood pressure, etc.) will give people an opportunity to identify problems early, giving them time to adjust their lifestyle or possibly seek some other type of treatment (e.g., taking medication).

The Importance of Early Awareness and Intervention

Gaining and maintaining awareness of what contributes to the health of the kidneys can help protect the kidneys.

Gaining awareness of and taking action against hidden risks, such as high blood pressure or chronic stress, and making positive changes to your lifestyle will help maintain kidney function and minimize the likelihood of developing long-term complications in the future.

Early intervention is the most effective method for protecting the health of your kidneys.

In my early years of clinical practice, it was not uncommon to see children admitted with severe measles, struggling with complications that could turn fatal.

Polio was not a chapter in textbooks—it was visible in outpatient clinics, in children who came in with permanent disabilities, and in families learning to cope with lifelong consequences.

Vaccines Save Lives: From Polio To COVID

Diarrheal diseases filled pediatric wards, often pushing already fragile children to the brink. These were not isolated cases; they were a pattern we saw far too often. What changed this reality was not a coincidence. It was vaccines.

Over the years, I have witnessed firsthand how immunization has transformed pediatric care in India. The introduction of the measles vaccine in 1985, followed by the second dose in 2010, has brought us to a point where a disease once feared by every parent is now on the verge of elimination.

Similarly, the impact of the Pulse Polio Immunization campaign has been extraordinary. From routinely seeing children affected by polio, we moved to a historic milestone—India being declared polio-free on March 17, 2014. For clinicians who have seen both sides, this shift is nothing short of remarkable.

The change has been equally significant in other areas. There was a time when severe diarrhea dominated pediatric admissions. Today, with better sanitation and the introduction of the rotavirus vaccine in 2016, we see far fewer cases of severe rotavirus-related illness. This is not just a statistic—it is reflected in fewer hospital admissions, less distress for families, and better outcomes for children.

More recently, during the COVID-19 pandemic, the importance of vaccines became evident on an unprecedented scale. As healthcare providers, we experienced the strain of the pandemic firsthand. The introduction of vaccines in January 2021 marked a turning point. It not only reduced the severity of illness but also brought a sense of control in an otherwise uncertain situation. The ability to protect lives at such a scale reaffirmed what medicine has known for decades—vaccines are among the most powerful tools we have.

Across diseases, across decades, and across generations, one truth remains consistent: vaccines save lives. However, despite these clear gains, we are now witnessing a concerning shift.

Vaccine Hesitancy And Emerging Diseases

In recent years, vaccine hesitancy has started to emerge—even among well-informed populations. As a clinician, this is deeply concerning. When diseases become less visible, people begin to underestimate their impact. Questions arise, doubts increase, and misinformation often fills the gap.

The consequences of this are already visible globally. The re-emergence of measles in countries with strong healthcare systems is a clear warning.

As per CDC data from March 18, 2026, the United States has reported 1,362 confirmed measles cases across 20 states, with multiple outbreaks—after more than two decades of control. This is not due to a lack of availability of vaccines, but due to reduced uptake.

From a medical standpoint, this is both predictable and preventable. Vaccination is not just about protecting one individual—it is about safeguarding entire communities. In my practice, I often remind families that immunization protects not only their child but also those who are more vulnerable—newborns, pregnant women, and individuals with weakened immunity. When vaccination rates decline, this collective protection weakens, and diseases find their way back.

History has shown us that progress in public health is not permanent unless it is sustained. The absence of disease does not mean the absence of risk—it often reflects the success of prevention.

Timely Immunization Is Key

The way forward is clear. We must continue to ensure timely immunization, strengthen awareness, and address concerns with clarity and empathy. As healthcare providers, it is our responsibility to build trust and provide evidence-based guidance. As a community, it is equally important to rely on science and not misinformation.

Vaccines have already proven their value—both in data and in daily clinical practice. The science is robust, the outcomes are visible, and the impact is undeniable. The question is no longer whether vaccines work. The question is whether we will continue to trust and use them.

Because the cost of inaction is not theoretical—it is seen in preventable illness, avoidable hospitalizations, and lives that could have been saved. For every generation, vaccines have worked. It is now our responsibility to ensure they continue to.
