Global warming is changing how diseases spread, and dengue fever is a prime example. Once mostly found in tropical areas, this mosquito-borne illness could increase by as much as 76% in parts of Asia and the Americas by 2050.

This is according to a new, comprehensive study that found that even small increases in temperature are significantly boosting the disease's spread. The research provides the first direct evidence that a warming climate has already made dengue more widespread.

Dengue fever can cause flu-like symptoms, and without proper care, it can lead to severe bleeding and even organ failure.

What Does "Goldilocks Zone" for Dengue Mean?

Mosquitoes that carry the dengue virus do best in a certain temperature range. The number of dengue cases is highest when the temperature is around 82°F. This "Goldilocks Zone" means that a small rise in temperature can cause a big increase in the disease. For example, places that were once too cool for dengue are now becoming perfect for it, leading to a big increase in cases in countries like Mexico, Peru, and Brazil.

The study found that climate change was responsible for an extra 4.6 million dengue infections each year between 1995 and 2014. Depending on how much more the planet warms, cases could go up by another 49% to 76% by 2050.

How Can We Protect Our Health From Rising Dengue?

With warmer weather and the monsoon season, there's a sharp rise in diseases like dengue and malaria, as well as viral fevers and respiratory infections. According to Dr. Neha Sharma, Attending Consultant at Fortis Hospital, these illnesses can severely affect vital organs. For example, dengue can harm the liver and platelets, while untreated malaria may damage the kidneys and brain. Dr. Sharma advises people to be aware of the early symptoms, such as:

• Persistent high fever
• Severe body ache and rashes
• Sudden fatigue or unexplained vomiting
• Sudden breathlessness or a drop in urine output

If you experience these symptoms for more than 48 hours, she recommends getting blood tests like a CBC, dengue NS1, and malaria antigen test to get an early diagnosis. Other important diagnostic tools include a chest X-ray and an ultrasound of the abdomen. She also highlights crucial precautions that are often overlooked:

• Avoid walking in floodwaters to prevent infections like leptospirosis.
• Regularly clean AC filters and damp areas to stop bacterial and fungal growth.
• Stay well-hydrated, as dehydration can worsen these infections.
• Do not self-medicate with painkillers or antibiotics, as this can hide symptoms and lead to worse complications.

How Can Be Combat Illnesses Like Dengue On A Global Scale

The researchers say their estimates are likely on the conservative side, as they don't include data from large areas like India or Africa where detailed information is hard to get. The recent appearance of dengue cases in parts of the U.S. and Europe shows that the disease is already expanding its reach. To combat this growing threat, the study highlights two crucial approaches:

Climate Mitigation

By reducing greenhouse gases, we can lessen the future spread of dengue. By reducing greenhouse gases, we can lessen the future spread of dengue.

Adaptation

We need to improve ways to control mosquitoes, make our healthcare systems stronger, and get ready to use new vaccines.

The findings from this study could also be used to hold governments and companies accountable for the damages caused by climate change. As one of the study's authors noted, climate change is not just about the weather—it's having a direct and dangerous effect on human health.

Infertility impacts millions across the globe, touching both men and women alike. According to the World Health Organization, around 17.5% of the global population, roughly one in six people, experience fertility challenges. This condition can significantly reduce or even prevent natural conception.

Yet, despite its prevalence, infertility remains clouded by myths and misconceptions, many of which unfairly place the blame solely on women. Seeking to debunk these long-held beliefs, Dr. Holly Miller, an American Board-certified obstetrician and gynecologist, took to Instagram to share three important truths every woman should know about fertility.

3 Truths About Fertility Women Should Know

With the help of modern medicine and medical interventions like IVF, fertility treatment can help people boost their chances of reproducing.

Infertility Isn't Just a Woman's Issue

It’s important to understand that infertility affects both partners — it’s not solely a woman’s issue. Blaming only the woman is both unfair and inaccurate. In fact, experts find that the causes of infertility are almost evenly split between men and women.

Roughly one-third of infertility cases are linked to the woman, another third to the man, and the remaining third result from issues affecting both partners — or from causes that doctors are unable to clearly identify.

To identify the cause of infertility, both partners should undergo testing simultaneously. For men, a semen analysis — a quick and straightforward test — is often the easiest and most informative first step.

The "Wait One Year" Rule Changes with Age

Most couples automatically try to conceive for a full 12 months before they think about seeing a fertility doctor. However, the doctor emphasizes that the woman's age is the single most important factor that affects the chances of successful treatment.

If you are under 35 years old: You can safely try for a full 12 months of regular, unprotected sex before seeking a specialist.

If you are 35 or older: You should contact a specialist after only 6 months of trying without success.

If you are 40 or older: You need to see a specialist right away—as quickly as you possibly can.

The doctor explains that after age 35, the woman's egg supply starts to decline more quickly. Time is essential, so couples should strongly ask their doctors for an early referral.

"Unexplained Infertility" Often Means "Undiagnosed Problem"

When a couple is diagnosed with "unexplained infertility," which happens in about 10% to 20% of cases, it means the basic first tests did not find a clear reason. This can be upsetting, but it does not mean you can never have children. In the doctor's experience, the term "unexplained" often means there are hidden problems, such as:

• Small issues with the male partner's sperm that were missed by the basic tests.
• A hidden condition called Endometriosis, which can only be confirmed by a surgical procedure.
• Not having sexual intercourse at the best time or not often enough.

In today's corporate world, desk jobs have become the order of the day and so are the health problems associated with them. Endless typing, long hours of sitting, and poor posture are silently taking their toll on young professionals who spend most of their day glued to screens. Many don't realize that their daily work habits could trigger unexpected medical conditions.

Such a growing concern was once highlighted by Hyderabad-based neurologist Dr Sudhir Kumar, who recently shared a case on X. He wrote about one such case of Riya (name changed), a 25-year-old software engineer who developed a sharp, burning pain in her elbow-a pain which began as a minor ache while typing and gradually became so severe that even lifting a teacup felt unbearable.

What was the cause of the sharp elbow pain that Riya experienced?

Riya tried everything she could think of: Rest, pain relief balms, painkillers, even switching hands while using her computer, but the pain refused to fade. When she finally decided to visit the doctor, her symptoms immediately pointed to something unexpected: Tennis elbow. The diagnosis came as a surprise, considering she had never even held a tennis racket. On examination, Dr Sudhir Kumar found the tell-tale signs of the condition, medically known as lateral epicondylitis — tenderness along the outer elbow and pain when she tried to extend her wrist. He explained that the culprit wasn’t a sport, but repetitive strain from long hours at the computer — a problem increasingly common among desk workers.

What is Tennis Elbow?

The Mayo Clinic describes tennis elbow, medically termed lateral epicondylitis, as a painful condition resulting from the overuse of muscles and tendons in the forearm. It develops where these tissues are repeatedly strained by similar wrist and arm movements, leading to tiny tears and inflammation near the elbow.

The name is misleading, and you don't have to be an athlete to get tennis elbow. As a matter of fact, most people who develop it never have used a racket. It's common for the condition to strike people in jobs that require repetitive motions: plumbers, carpenters, painters, butchers, and yes, office workers who spend hours typing or using a mouse.

The pain generally arises on the outside of the elbow, precisely at that bony prominence to which the muscles of the forearm attach. For some, the discomfort may extend into the forearm or even the wrist, making most activities quite arduous.

How Can Tennis Elbow Be Treated?

Once the diagnosis was confirmed, Dr Sudhir Kumar focused on addressing the underlying cause — repetitive stress and poor workstation ergonomics. The holistic treatment for Riya included the following:

• Avoided repetitive activities that triggered her pain.
• Adjusting the computer setup and improving posture.
• Establish a physiotherapy regimen to stretch, strengthen, and gradually build muscle endurance.
• A short course of anti-inflammatory medication

Employing a counterforce brace-a tennis elbow strap-to reduce strain in daily activities. By her six-week follow-up, Riya’s pain had completely resolved. Her grip strength was back, and she could type, lift, and exercise without discomfort. Three months later, she was symptom-free — and far more aware of how small ergonomic changes can make a big difference.

Prostate cancer is one of the leading causes of cancer deaths, however, a recent survey showed that most people don’t know this vital fact about prostate cancer symptoms.

Prostate cancer is a serious illness in the US, affecting over 300,000 men each year and causing more than 35,000 deaths, according American Cancer Society. This makes it the second-most deadly cancer for men. If doctors detect the disease early, it is treatable. However, patients usually don't notice any signs of the disease in its beginning stages. Due to this lack of symptoms, checking for the disease is extremely important.

A recent survey of 1,004 U.S. adults, commissioned by the Ohio State University Comprehensive Cancer Center, aimed to gauge public knowledge of the disease. The findings highlight a critical need for better education.

What Do Americans Know About Early-Stage Prostate Cancer?

The results showed that most people, 80% of those surveyed, are unaware that early prostate cancer usually has no physical symptoms. One health specialist noted that it's crucial for everyone to understand that this cancer causes no symptoms until it has become advanced. The survey also revealed other gaps in knowledge:

• More than half of the people surveyed (59%) did not know that changes in sexual function could be a sign of prostate cancer.
• The survey noticed some differences across groups. For example, one minority group was better at identifying less common signs like tiredness and weight loss.
• However, that same minority group was less likely than others to correctly identify that the cancer usually has no symptoms in its early stage.

What Is The Best Way To Diagnose Prostate Cancer?

The fact that prostate cancer often begins without symptoms is the main reason doctors worry.

Lack of Symptoms

In its early phase, the cancer is small and contained within the prostate gland. It doesn't push on or block any other body parts, so it doesn't cause pain or discomfort. Because the cancer is deep inside the body, it's hard to tell if someone has it without special tests.

Provider Worry

Because men feel fine, they may wrongly believe they aren't at risk. This feeling of being safe often makes men hesitant to get screened. Since there are no symptoms to look for, screening tests, usually a simple blood test or a physical exam, are the best way to find the cancer early.

What Are Some Signs of Prostate Cancer?

Even though most men with early prostate cancer feel completely normal, there are certain signs that might appear if the disease is more advanced. These symptoms include:

• Having trouble starting to urinate.
• Having a urine flow that is weak or stops and starts.
• Needing to urinate often, especially during the night.
• Difficulty completely emptying the bladder.
• Feeling pain or a burning sensation while urinating.
• Noticing blood in the urine or semen.
• Feeling pain in the back, hips, or pelvis that doesn't go away.
• Experiencing pain during ejaculation.

When Should You Get Screened For Prostate Cancer?

According to American Cancer Society, health organizations advise men to talk with their doctors about getting checked for prostate cancer starting at certain ages, depending on their personal risk.

Average Risk: Age 50

Men who have no special risk factors.

High Risk: Age 45

Men who are African American or who have a father or brother who was diagnosed before age 65.

Highest Risk: Age 40

Men who have more than one close relative (father or brother) diagnosed at an early age. There is no one-size-fits-all advice for screening. Men should always speak to their doctor about their own risk and discuss the pros and cons of testing. Since there are no early warning signs, talking to a doctor about screening is described as "critical" and a simple process that could potentially save a man's life.
