The current measles outbreak has gripped US states like Texas and New Mexico leaving people worried whether it would become a new pandemic. According to the Texas Department of State Health Services as of February 21, 90 cases were diagnosed in the last month in the South Plains area, with at least 77 of them were reported in children and teens under 17.

Measles is highly contagious and can be deadly. The outbreak, which started spreading in late January, has resulted in multiple hospitalizations, with at least nine confirmed cases and three probable cases as of early February. Health officials caution that at least one in five infected individuals will have to be hospitalized, highlighting the severity of the situation.

Misinformation surrounding vaccines and with the new Trump administration anti-vaccine campaigs, has causing parents to hesitate or refuse vaccination.

Furthermore, the country down under Australia is also witnessing a surge in measles cases as health officials in Sydney have issued an urgent alert, urging residents to watch for measles symptoms after an infected individual visited several places in Sydney over the last seven days.

Authorities report that the traveller had returned from South East Asia where there are ongoing outbreaks of measles.

What Are The Symptoms Measles?

Key symptoms of measles include fever, a runny nose, sore eyes, and a cough. Typically, a red, blotchy rash appears three to four days later, spreading from the head down to the body. Symptoms can manifest between 7 and 18 days after exposure.

Anyone who experiences these symptoms after potential exposure should immediately contact their doctor or emergency department. It is crucial to call ahead before visiting to avoid potentially exposing others in the waiting room. Dr. Selvey also highlighted that ongoing measles outbreaks are occurring in various parts of the world, making awareness and prompt action essential.

Why It Is Important To Get Vaccinated?

According to CDC everyone should get the MMR vaccine. It protects you from measles, mumps, and rubella. Getting vaccinated helps stop these diseases from spreading. There are two safe MMR vaccines available. They work the same way, so it doesn't matter which one you get. Kids can also get a shot that protects against chickenpox too, but this is only for children.

Who Should Get Vaccinated?

Kids Need Two Shots

All children should get two MMR shots. The first shot should be given when they are between 12 and 15 months old. The second shot should be given when they are between 4 and 6 years old. If needed, the second shot can be given earlier, but it must be at least 28 days after the first shot.

College Students Need to Be Protected

Students going to college or other schools after high school, need two shots if they are not already immune. The shots must be at least 28 days apart.

Adults Need at Least One Shot

Most adults need at least one MMR shot. Some adults need two shots, especially those who work in healthcare, travel a lot, or go to college. These people should get two shots, with 28 days between them.

Travelers Need to Be Extra Careful

Anyone traveling to other countries should make sure they are protected. Babies 6 to 11 months old should get one shot before traveling. Kids 12 months and older, teens, and adults need two shots, with 28 days between them.

Healthcare Workers Must Be Immune

People who work in healthcare should have proof that they are immune to measles, mumps, and rubella. If they are not immune, they need two MMR shots, spaced 28 days apart.

Women Thinking About Having Babies

Women who might get pregnant should talk to their doctor about the MMR vaccine. It's safe to get the shot while breastfeeding.

Alzheimer’s patients have received discouraging news after the release of results from a major study. Novo Nordisk confirmed that its Alzheimer’s treatment did not show a “statistically significant” slowdown in the progression of the illness. Two trials evaluating the company’s weight loss medicine semaglutide in Alzheimer’s disease did not meet their targets, the firm said on Monday, as the drug failed to slow decline compared with a placebo.

Testing semaglutide, the active ingredient in Ozempic and Wegovy, for Alzheimer’s had always been viewed as a high-risk attempt, even though research has suggested the drug may influence several processes beyond metabolism. Still, Novo had raised interest in recent weeks by advertising roles connected to Alzheimer’s consumer marketing and medical affairs.

Novo Nordisk Says Alzheimer's Drug Trial Fails

Novo Nordisk said on Monday that an older oral form of semaglutide did not achieve its main outcome in late-stage trials assessing whether the drug could reduce cognitive decline in people with Alzheimer’s disease, sending its shares down by 10 percent.

The development dims expectations that Alzheimer’s could become a major new area for GLP-1 medicines like semaglutide, at a time when Novo is facing stronger competition for its leading products in obesity and diabetes. Treatment choices for Alzheimer’s patients remain limited. The company’s study had been closely followed as a potential sign of whether GLP-1 drugs, widely used for diabetes and weight control, might slow the condition’s advance.

The pill tested was Rybelsus, approved only for type 2 diabetes and containing semaglutide, as reported by Reuters.

Novo Nordisk: Lottery Ticket Fails

The firm’s Executive Vice President for Product and Portfolio Strategy, Ludovic Helfgott, had earlier described the Alzheimer’s trials as a “lottery ticket,” reflecting both the uncertainty and the considerable promise involved. Alzheimer’s and related dementias affect more than 55 million people worldwide, and no cure exists. “While semaglutide did not demonstrate efficacy in slowing the progression of Alzheimer’s disease, the extensive body of evidence supporting semaglutide continues to provide benefits for individuals with type 2 diabetes, obesity, and related comorbidities,” Chief Scientific Officer Martin Holst Lange said in a statement.

The findings from the two early-stage studies, EVOKE and EVOKE+, mark another setback for the Danish company and its new CEO Mike Doustdar. Novo had experienced remarkable success with Ozempic and Wegovy, but slower sales growth and a sharp drop in its stock value led to a leadership shift and significant job cuts.

The disappointment adds weight to analysts’ doubts about Novo’s Alzheimer’s plans, with UBS having earlier estimated only a 10 percent likelihood of success.

Novo Nordisk: Alzheimer’s Trial Stakes And Outcome

Alzheimer’s, marked by deep cognitive decline, fading memory and changes in behaviour, remains one of the hardest challenges in drug research. Novo had repeatedly acknowledged the uncertainty surrounding these studies. Even so, the possible payoff was significant. Analysts at Morgan Stanley had estimated that a breakthrough could have added up to $5 billion in yearly revenue.

“We believed it was important to assess whether semaglutide could offer any benefit,” Chief Scientific Officer Martin Holst Lange said, referring to the drug better known as Ozempic. The treatment did show improvement in certain biological markers connected to Alzheimer’s, but these gains did not lead to a slower progression of the condition.

Novo Nordisk Stock: Impact On Competition And Obesity Market

The company is also working to strengthen its footing in the obesity sector. Any sign that Wegovy could influence the most common form of dementia might have provided an edge over Eli Lilly’s Zepbound in the United States, where competition in this field is intensifying.

Delhi residents are once again dealing with heavy pollution as a dense layer of smog covered the city on November 22. In response to the worsening situation, the Commission for Air Quality Management (CAQM) on Saturday put GRAP Stage IV curbs into force, as several monitoring stations across the Capital recorded air in the ‘severe’ category.

Under the updated rules, the Government of National Capital Territory of Delhi and the NCR state administrations will decide whether public, municipal and private offices should function with only half their staff on site, with the remaining employees working from home. CAQM noted in its latest advisory, “CAQM has revised the GRAP schedule on 21.11.2025 to make it more stringent thus preventing further deterioration of air quality in Delhi-NCR.”

Which Measures Of GRAP 4 Are Being Taken Under GRAP 3?

As per CAQM, the following GRAP 4 steps will now be implemented during GRAP 3:

• NCR state governments and GNCTD will consider allowing public, municipal and private offices to operate at 50 percent capacity, with the remaining staff working remotely.
• The Central Government may also take a call on offering work-from-home options for employees in central government offices.

Other Restrictions In Delhi Under GRAP 3

Since GRAP 3 remains active in Delhi, activities such as non-essential construction, demolition work, and the use of older vehicle categories, including those below the Bharat Stage (BS)-IV emission norms, continue to be limited. People have been advised to minimise time spent outdoors, especially during the early mornings and late evenings when pollution is often at its peak. On Friday, the Delhi government also directed schools and other educational institutions to halt all sports and outdoor physical activities.

Stages of GRAP

GRAP follows four levels, each tied to the Air Quality Index (AQI) at the time.

Stage I of GRAP begins when air quality reaches the “poor” range (AQI between 201 and 300, which can cause breathing discomfort after prolonged exposure).

Stage II is enforced when air turns “very poor” (AQI between 301 and 400, which can result in respiratory issues with continued exposure).

Stage III comes into effect when pollution becomes “severe” (AQI between 401 and 500, a level at which even healthy individuals may feel the impact and those with existing conditions face serious health risks).

Stage IV of GRAP is declared when pollution crosses into the “severe+” range (AQI above 500).

India’s national AQI framework, created by the Central Pollution Control Board (CPCB), categorises air quality based on its potential impact on health, ranging from mild discomfort to significant respiratory and heart-related problems.

Each stage of GRAP includes a fixed set of actions for authorities to follow. As pollution increases and GRAP moves to the next stage, measures from earlier levels continue. This creates a step-by-step response system designed to slow down the rise in pollution and prevent conditions from becoming even more harmful.

At the moment, GRAP III is in force in Delhi, as air quality has been shifting between the ‘severe’ and ‘very poor’ bands. A range of restrictions linked to this stage is already being implemented across the city.

As Delhi’s air grows heavier with pollution, citizens have begun stepping out in protest to raise their concerns. During a demonstration at the C Hexagon near India Gate, some protestors allegedly sprayed chilli solution on police officers, disrupted official duties and blocked traffic, according to the police. New Delhi DCP Devesh Kumar Mahla stated that this was the first time such a substance had been used against officers during an agitation. “For the first time, we witnessed chilli spray being used on police personnel. A few officers were hit in the eyes and are receiving care at RML Hospital. Legal action is underway,” the Delhi Police official told The Print.

This raises an important question. How harmful can a chilli spray actually be? Can spraying it put a person’s organs at risk? Here is a closer look.

How Is Chilli Spray Made?

Chilli spray, often known as pepper spray, is produced from oleoresin capsicum (OC), an oily extract taken from chilli peppers. Its main active compound is capsaicin, the same substance that gives chillies their heat, only in a far more concentrated and weaponised form.

The OC is mixed into a liquid base (such as water with an emulsifier like propylene glycol, or an alcohol solution) and is then pressurised so it can be dispersed as a fine aerosol spray, according to The Wire Science.

Physical Effects Of Chilli Spray

When pepper spray reaches the eyes, it brings on sudden eyelid closure, sharp pain and temporary loss of vision. Many describe the sensation as burning, bubbling or boiling, along with intense discomfort, as per Medical News Today.

It may also lead to:

• dry cough or wheezing
• shortness of breath or trouble drawing in air
• burning in the throat
• chest discomfort
• gagging
• runny nose
• gasping
• panic
• difficulty speaking
• dizziness
• fainting
• rashes, blisters or chemical burns where it touches the skin

How Does Chilli Spray Exposure Harm Your Airways?

Chilli spray affects your airways by provoking strong inflammation and irritation of the moist lining inside the nose, throat, and lungs. Capsaicin is the key driver of this reaction, and it can spark a wide set of breathing symptoms. In more serious instances, it may even lead to complications.

Chilli Spray Exposure To Eyes

The eyes react almost instantly to pepper spray. It causes heavy tearing, swelling, redness, stinging and momentary blindness. The cornea’s surface layer becomes disturbed, which means people with conditions like diabetes, dry eyes or recurrent corneal erosion may experience stronger effects than someone with healthy eyes, as reported by Medical News Today.

Anyone wearing contact lenses should remove them at once using clean fingers that have not touched the spray. The lenses must be thrown away because they cannot be salvaged.

Rubbing the eyes will make the pain far worse and should be avoided. Rinsing gently with saline can help. Blinking repeatedly also assists in washing the irritant out with tears.

What To Do After Exposure To Chilli Spray?

After being exposed to pepper spray, these steps can help shorten the discomfort:

• Move to an open area with clean air if possible.
• Rinse the affected parts with plenty of water to clear away the chemical.
• Do not use soap near the eyes, because it can aggravate irritation.
• Remove clothing that has come into contact with the spray to prevent the chemical from spreading. Cutting it off instead of pulling it over the head reduces further exposure to the eyes and skin.
• Keep hands away from the irritated areas to avoid transferring the oily chemical elsewhere on the body.
• Blink quickly to help tears flush out the substance.
