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.

Across social media, videos of mothers shaving their daughters’ upper-lip hair have been going viral. In many clips, parents say they are trying to protect their children from bullying about facial hair, something many women recall experiencing during their own childhood. Some of these videos show girls as young as 10 or 12 getting their first facial shave at home.

The conversation gained major traction in 2023 when influencer Vidya Gopalan posted a video of herself shaving her 12-year-old daughter’s facial hair. The clip clocked millions of views and sparked strong reactions. While many viewers praised the mother for being proactive, others felt the practice introduces children to beauty pressures far too early.

Similar videos continue to trend today, often framed as an act of care from parents who want their children to feel confident. But dermatologists say the issue is more complicated than it looks online.

Children’s Skin Is More Sensitive Than Adults’

Experts point out that children’s skin is very different from adult skin. The protective barrier is still developing, which means it is more vulnerable to irritation and injury.

When shaving is done too early or too frequently, it can cause redness, cuts, razor bumps and sometimes infections. Using adult razors, dull blades or harsh products can make the situation worse. Even small nicks on delicate facial skin can lead to inflammation or long-lasting irritation.

Dermatologists note that shaving itself is not inherently dangerous if done correctly and occasionally. However, it should not become a routine practice for very young children simply because it is trending online.

Instead, any decision about hair removal should be taken carefully, with proper hygiene and supervision.

The Myth About Hair Growing Back Thicker

One reason many parents feel comfortable allowing shaving is the belief that hair will grow back thicker anyway, so removing it early does not change much.

Experts say this idea is a long-standing myth.

When hair regrows after shaving, the blunt edge of the cut hair can make it appear darker or thicker. In reality, the hair shaft itself has not changed. Studies in dermatology have repeatedly shown that shaving does not alter hair thickness, color or growth rate.

However, frequent shaving may still irritate sensitive skin, which is why dermatologists recommend caution when it comes to young children.

Cosmetic Treatments Raise Bigger Concerns

The debate intensified further after reports surfaced about an eight-year-old undergoing laser hair removal. That revelation shocked many people online and pushed the conversation beyond simple grooming.

Dermatologists stress that laser hair removal is generally designed for teenagers or adults whose hormones have stabilized. During childhood, hair growth patterns can still change significantly as the body develops. Because of this, such procedures are rarely recommended for younger children.

The concern is not only medical but also psychological. Starting cosmetic treatments too early may reinforce the idea that natural body features need to be “fixed.”

The Real Issue May Be Body Image

Experts say the larger conversation should not revolve only around hair removal techniques. It should also address how children learn to view their bodies.

Facial hair during puberty is normal, and it varies widely depending on genetics and hormones. In countries like India, where darker hair is common, many children may notice upper-lip hair earlier than their peers.

Instead of immediately removing it, dermatologists encourage parents to talk openly with their children about body changes. Helping children build confidence and understand that these changes are natural can be just as important as addressing appearance concerns.

If a child feels genuinely uncomfortable, gentler options such as a soft facial trimmer or consulting a dermatologist may be considered. But experts say the goal should not be to rush into grooming habits simply because social media has normalized them.

Sometimes, the most important step is helping children realize that their bodies are not a problem that needs fixing.

An international team of researchers has developed an artificial intelligence (AI)-based tool that can significantly improve care for glaucoma -- a leading cause of irreversible blindness worldwide, according to a study published in The Lancet Primary Care journal today.

Researchers led by those from the University of Lisbon in Portugal found that the AI-based screening tool halved the number of unnecessary referrals for glaucoma.

The study, released during the Glaucoma Awareness Week, also showed an accuracy level at par with human eye doctors.

"The high accuracy at excluding people without glaucoma is especially important, as false alarms can lead to unnecessary hospital visits, patient anxiety, and added strain on healthcare services," the researchers said.

According to the researchers, AI-based screening could:

• support earlier detection,
• reduce unnecessary specialist referrals,
• prevent avoidable vision loss,
• can be integrated into routine primary care in a cost-effective way

Key Findings

The study was carried out at a single screening center in Lisbon, Portugal, in 2023.

The experts screened 671 adults aged 55-65 for glaucoma via the AI tool, analyzing images of the eyes. The images were then independently graded by six glaucoma experts.

The AI-tool:

• referred 66 people (9.8 percent) vs 118 referrals (18.0 percent) by the eye doctors,
• diagnosed glaucoma in 40 participants (6.4 percent).
• It correctly identified 78 percent of people who truly had glaucoma, vs 75 percent identified by the eye doctors
• Correctly ruled out the disease in 95 percent of people, vs 91 percent by eye doctors

While modelling studies suggest that screening could substantially reduce glaucoma-related visual impairment and blindness, barriers include the need for specialised diagnostic equipment and trained personnel, particularly in low- and middle-income countries, and the intrinsically low positive predictive value of screening tests.

In such a scenario, the new study showed that "AI may provide a more viable option than population-wide screening", which may seem impractical.

What Is Glaucoma?

Glaucoma is a chronic disease that affects an estimated 80 million individuals globally, according to the World Glaucoma Association.

It is a progressive, degenerative disorder of the optic nerve that produces characteristic visual field damage.

The disease stems from a long asymptomatic phase, resulting in substantial underdiagnosis and delayed treatment.

Even in high-income countries, up to 50 percent of individuals with glaucoma remain undiagnosed, frequently presenting moderate to advanced disease at first detection.

By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma.

When to see a doctor for glaucoma:

• Vision suddenly gets blurry
• Severe eye pain
• Headache
• Nausea
• Vomiting
• Rainbow-colored rings or halos around lights

In adults, long periods of sleep deprivation has been linked to problems such as weakened immunity, weight gain, depression, and an increased risk of dementia. However, scientists are now paying closer attention to how sleep affects the brain much earlier in life.

However, a new University of North Carolina School of Medicine study suggests that disrupted sleep during early childhood may interfere with key stages of brain development and asl well as increase the risk of developing autism.

Why Sleep Matters For The Developing Brain

Sleep plays a crucial role in helping these synapses form and strengthen. During sleep, the brain organizes and stabilizes these neural connections, shaping the foundation for future brain function. If sleep is repeatedly disrupted during this delicate stage of development, the process may be affected.

Frequent waking or sleep disturbances could interfere with how these neural connections are formed, potentially influencing behavior and cognitive abilities later in life.

The Link Between Sleep And Autism

“The unique effects of sleep loss during development are largely unexplored,” Diering said. “Our data show that babies and children are more vulnerable to the negative effects of sleep disruption. We also found that sleep loss during this crucial period of time can negatively interact with underlying genetic risk for autism spectrum disorder.”

Sleep problems are already known to be common in people with autism. In fact, sleep disruption has been reported in more than 80 percent of individuals with autism spectrum disorder. However, researchers have long debated whether these sleep issues are a cause of the disorder or a consequence of it. Understanding how sleep interacts with brain development could help scientists detect autism earlier and potentially develop new treatment strategies.

Studying Sleep Disruption In Early Life

In earlier work conducted in 2022, researchers examined how sleep disruption during early life might interact with genetic factors linked to autism. Using mouse models, they disrupted sleep during the third week of life, a developmental stage roughly comparable to ages one to two in humans.

The study found that sleep disruption during this period produced long lasting behavioral changes. Male mice that were genetically vulnerable to autism showed deficits in social behavior later in life. These results suggested that sleep disruption during critical stages of development may interact with genetic risk factors in ways that shape long term behavior.

Younger Brains Respond Differently To Sleep Loss

To investigate further, researchers studied how developing and adult mice respond differently to sleep deprivation.

Using specially designed housing systems equipped with sensitive sensors, scientists tracked the animals’ breathing and movement. This allowed them to determine when the mice were awake and when they were asleep.

The researchers observed that adult mice were able to compensate for lost sleep. After experiencing sleep deprivation, the adults increased their sleep later during their normal active period. This process, known as sleep rebound, allowed them to recover some of the lost rest.

Younger mice behaved very differently. They showed no sleep rebound at all, meaning they did not compensate for the sleep they had lost. This finding suggests that younger brains may be far more vulnerable to the effects of sleep disruption.

The consequences were also visible in cognitive performance. Sleep deprived young mice performed poorly on learning and memory tasks, while adult mice were significantly more resilient after losing sleep.

Changes At The Level Of Brain Synapses

The results showed that sleep deprivation in young mice significantly altered the formation of synapses. These changes were not seen in adult mice. “This now provides one of the largest and most comprehensive datasets to examine the molecular effects of sleep loss across the lifespan,” Diering said.

Potential Future Treatments

“Development is not something that one can go back and do again,” Diering said. “Sleep is important for the entire life and especially during development. Understanding what we know now will place greater emphasis on understanding sleep issues in ASD and could lead to an important therapeutic avenue to treat ASD and other developmental conditions.”

The findings highlight an important message for parents and caregivers. During early childhood, healthy sleep patterns may play a critical role in shaping the brain for years to come.
