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.

Indian drugmaker Dr Reddy's Laboratories is now gearing up to launch its generic semglutide injection in the country in March under the brand name Obeda, reported the news wire agency Reuters. Patent protection for semglutide expires in India in March 2025. This has triggered a rush among Indian drugmakers to come up with lower-cost versions.

Semaglutide is the active ingredient in Danish drugmaker Novo Nordisk's Ozempic and Wegovy, popularly known as the weight loss drugs, but also effective for diabetes and used primarily for that.

Indian Drugmakers Rush For Generic Weight Loss Drugs

Hyderabad-based Dr Reddy's already applied for trademark with the brand name Obeda and a logo, reported Reuters, based on a government filing. In an email response to Reuters, Dr Reddy's spokesperson said, "As semaglutide is yet to be officially launched, it would not be appropriate to refer to or publish any name as the brand name at this stage."

Other companies like Sun Pharma, Zydus Lifesciences, and Nacto Pharma too are entering the rat race of launching multiple generic versions to make the treatment more affordable for patients with obesity and weight-related health risks.

Sun Pharma also announced the plans for "day-one" launches of generic prefilled pens.

Will Launching Generic Weight Loss Drugs Make It Cheaper To Buy?

Until the patent is expired, the semaglutide therapies are owned by the original company. In India, semaglutide injections like Ozempic and Wegovy are soled at a high cost that has limited accessibility to many patients.

Industry analysts, as reported by NDTV, expect that one generic semaglutide enters the market from March 21, 2026, prices could be cut roughly by 50 per cent as compared to the prices it started with. This means Wegovy which was previously sold for around Rs. 10,000 per month could fall somewhere between Rs 3,500 to Rs. 4,000 per month for starter doses.

Dr Reddy's Laboratories have positioned their generic brands competitively, and could potentially offer discounts of up to 50 to 60 per cent in early competition.

How Does Semaglutide Work?

Semaglutide works as a GLP-1 receptor agonist that mimics the GLP-1 hormone to regulate appetite and blood sugar. It slows gastric emptying and makes you feel fuller longer. It also signals the brain to reduce hunger and cravings, and triggers the pancreas to release insulin when blood sugar is high.

They work by increasing insulin release in a glucose-dependent manner, decreasing the liver's production of glucagon, and slowing down the emptying of the stomach, which helps lower blood sugar levels after a meal. They also act on the brain to suppress appetite and increase feelings of fullness, leading to reduced calorie intake.

In people with type 2 diabetes, notes Harvard Health, the body's cells are resistant to the effects of insulin and body does not produce enough insulin, or both. This is when GLP-1 agonists stimulate pancreas to release insulin and suppress the release of another hormone called glucagon.

These drugs also act in the brain to reduce hunger and act on the stomach to delay emptying, so you feel full for a longer time. These effects can lead to weight loss, which can be an important part of managing diabetes.

Scientists for the first time ever developed antibodies that could block Epstein Barr virus or EBV. This is a pathogen that is estimated to infect 95 per cent of the global population. The Epstein Barr virus is also linked with multiple types of cancer, neurodegenerative diseases and other chronic health conditions.

Antibodies for Epstein Barr Virus: How Does It Work?

Scientists used mice with human antibody genes. The team then developed new genetically human monoclonal antibodies that would prevent two key antigens on the surface of the Epstein Barr virus from binding to entering human immune cells.

The findings are published in Cell Reports Medicine. The study shows how the newly identified monoclonal antibodies successfully block infection in mice with human immune systems when they had EBV.

Scientists View On The Antibodies That Block Epstein Barr Virus

"Finding human antibodies that block Epstein Barr virus from infecting our immune cells has been particularly challenging because, unlike other viruses, EBV finds a way to bind to nearly every one of our B cells," explained Andrew McGuire, Ph.D., a biochemist and cellular biologist in the Vaccine and Infectious Disease Division at Fred Hutch. "We decided to use new technologies to try to fill this knowledge gap and we ended up taking a critical step toward blocking one of the world's most common viruses."

What Was the Challenge In The Creation Of Antibodies To Block Epstein Barr Virus?

The key challenge was to pursue human monoclonal antibodies that could actually halt the Epstein Barr virus infection without triggering an anti-drug response to the antibodies themselves. This is a common response among patients who are treated with antibodies raised in other animals.

The researchers targeted two antigens namely: gp350, which helps EBV bind to cell receptors. The second antigen was gp42 that allows EBV to enter and infect human antibody genes. This has led to the monoclonal antibodies to work against gp350 and eight gp42.

"Not only did we identify important antibodies against Epstein Barr virus, but we also validated an innovative a new approach for discovering protective antibodies against other pathogens," noted Crystal Chhan, a pathobiology Ph.D. student in the McGuire Lab. "As an early-career scientist, it was an exciting finding and has helped me appreciate how science often leads to unexpected discoveries."

What Is Epstein Bar Virus (EBV)?

EBV is a highly contagious virus that can pass through bodily fluid contact. It is the cause of one of the most common infections, mononucleosis or mono. Once you get this virus, it stays in your body, inactive and in a dormant state until it becomes reactivated.

According to the Frontiers in Immunology, Chronic active Epstein-Barr virus (CAEBV) disease is a very uncommon problem where people's bodies can't fight off the EBV virus. It keeps getting worse, with a lot of the virus's DNA in their blood and the virus attacking their organs with infected blood cells.

People with this disease often have fevers, swollen glands, a big spleen, liver problems caused by EBV, or low blood counts. Over time, their body's ability to fight off infections gets weaker. If they don't get treatment, they can die from other infections, a problem where the body attacks its own blood cells, organ failure, or cancers linked to EBV.

The only treatment that has been proven to work for this disease is a stem cell transplant (a procedure to replace damaged blood cells with healthy ones). Right now, scientists are trying to figure out why this disease happens. They are looking at problems with the body's defense system (immune defects) and changes in people's genes that might be linked to the disease. A new study as also revealed that EBV may also cause us brain damage due to a disease called encephalitis.

Symptoms Of Epstein-Bar Virus

EBV infections do not cause symptoms especially for children, teens and adults are more likely to experience symptoms like fever, feeling tired or fatigued headache, sore throat, swollen lymph nodes in your neck and arm, enlarged spleen or swollen liver, body aches and skin rash. The symptoms of this usually last for two to four weeks. Things are a bit different with Chronic EBV. In rare cases of EBV, it can lead to a chronic condition called active EBV (CAEVB) some symptoms include, swollen and tender lymph nodes, fever, enlarged liver, fatigue, sore throat, headache, muscle pain joint stiffness, anemia and liver failure.

Meghalaya's Health Minister Wailadmiki Shylla has raised alarm over the rising HIV cases in the state, noting that 10,293 infected residents were receiving antiretroviral treatment.

Along with this, Shylla noted that nearly 750 people have died due to the condition in the past decade with East Khasi Hills district reporting 435 of those cases. Coming in second is West Jaintia Hills with 123 cases, East Jaintia Hills with 90 cases, Ri Bhoi with 51 cases and Eastern West Khasi Hills reporting 16.

Nine deaths in West Garo Hills, eight in West Khasi Hills, seven in South West Khasi Hills, three in South Garo Hills, two in South West Garo Hills, and one in North Garo Hills have also been recorded.

During a question hour in an assembly session on February 25, the official said: "It is very unfortunate, but Meghalaya is having the highest cases in India".

He also highlighted the confidentiality clauses in the HIV and AIDS Prevention and Control Act, 2017 as well as existing social stigma as major challenges in addressing the rampant spread of the issue. “Early detection and intervention get complicated because testing requires consent and treatment cannot be forced,” he said.

“The State government has sanctioned a ₹25-crore intervention program for the next five years to address the alarming rise in HIV/AIDS cases,” Shylla declared as well as assured that the Department has been intensifying awareness campaigns to improve testing and treatment.

The global challenge of HIV/AIDS remains one of the most pressing public health issues today. According to the latest data from UNAIDS, around 38.4 million people worldwide are living with HIV/AIDS.

As of 2024–2025, India has approximately 2.5 million to 2.56 million people living with HIV (PLHIV), marking the third-largest HIV epidemic globally, underlining the need for not only medical intervention but also comprehensive awareness, education, and social change.

What Is HIV?

HIV is the virus responsible for attacking the body’s immune system, specifically targeting CD4 cells, which are crucial for the body’s defense against infections. As HIV progresses, it destroys these cells, weakening the immune system over time. If left untreated, this continuous damage can lead to AIDS.

HIV is highly contagious and can be transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is primarily spread through unprotected sexual contact, sharing needles, from mother to child during childbirth or breastfeeding.

Without treatment, HIV progresses through three stages:

- Acute HIV Infection: This stage occurs shortly after transmission and may include symptoms like fever, fatigue, and swollen lymph nodes.

- Chronic HIV Infection: Often asymptomatic or mildly symptomatic, the virus continues to damage the immune system but at a slower rate.

- AIDS: This is the final stage, marked by severe immune damage and the presence of infections that take advantage of the compromised immune defenses.

The disease is diagnosed through blood tests or oral swabs that detect the presence of the virus or antibodies produced by the immune system in response to the virus. Early detection of HIV is crucial, as it allows for timely intervention and treatment, which can prevent the virus from progressing to AIDS.

For HIV, the primary treatment goal is to suppress the virus to undetectable levels, thus maintaining a strong immune system and preventing further transmission of the virus. People living with HIV can often live long, healthy lives if they adhere to antiretroviral therapy (ART).

What's Happening In Mizoram?

Mizoram Health Minister Lalrinpuii has expressed serious concern about rising HIV cases, as data shows that cases in the state are 13 times higher than the national average.

Calling it a "collective disgrace", Lalrinpuii said: “About 70 per cent of HIV transmissions in Mizoram occur through sexual contact. While the national prevalence rate stands at a mere 0.2 per cent, Mizoram’s rate has climbed to 2.74 per cent. This is a matter of shame for Mizo society.”

Speaking at an event organised for International Condom Day in Aizawl on February 13, she noted that a majority of that sexual contact remains the primary route of HIV infections in the state, accounting for 70 per cent of all cases.

The minister noted that the spread is largely driven by infidelity and a lack of preventive measures, which she argued contradicted the moral and religious values of the Mizo society.

She urged the people of the state to remain faithful to their partners. “To protect the future of Mizoram, our youth must remain vigilant,” Lalrinpuii added.
