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.

The US Food and Drug Administration (FDA) has announced that Midwest Poultry Services is voluntarily recalling nearly 1.6 million dozen eggs due to possible Salmonella Enteritidis contamination.

The recalled eggs were produced and distributed from Texas farms between June 6 and July 3, 2026, with "sell by" or "best by" dates between July 20 and August 17, 2026.

"Midwest Poultry Services, L.P. is voluntarily recalling 1,589,577 dozen white shell eggs and brown cage free shell eggs produced in Texas because they have the potential to be contaminated with Salmonella Enteritidis" the FDA said in a statement.

While no ⁠illnesses reported were linked to the Midwest Poultry Services eggs as of the announcement, Midwest Poultry Services has halted distributing eggs produced on ⁠its Texas farms, the health regulator said.

Which Eggs Have Been Recalled?

The recall includes white shell eggs and brown cage-free shell eggs produced in Texas with "sell by" or "best by" dates between July 20 and August 17, 2026, according to Midwest Poultry Services.

Where Were the Recalled Eggs Sold?

According to the FDA, the recalled eggs were shipped to foodservice and retail customers in Texas, Oklahoma, and Louisiana.

They were sold at:

• Kroger stores in Texas and Louisiana
• Brookshire Grocery stores in Texas, Oklahoma, Arkansas, Louisiana, New Mexico, and Mississippi
• Other smaller retail outlets

The company said it identified the issue at its two Texas farms through proactive environmental monitoring and root cause analysis. It has also halted distribution of fresh eggs produced at its Texas farms.

Consumers who purchased the recalled eggs are advised not to consume them and to return them to the place of purchase for a full refund.

Salmonella: Symptoms and Risks

Salmonella is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems.

According to the FDA, the contamination involves Salmonella Enteritidis, a strain of Salmonella bacteria commonly associated with contaminated poultry and eggs and one of the leading causes of human salmonellosis worldwide.

Salmonella infection can manifest with a range of unpleasant symptoms, typically including diarrhea, fever, vomiting, stomach cramps, and dehydration. While most healthy individuals tend to recover within about a week without specific medical intervention, the infection can lead to more serious and potentially life-threatening illness in certain vulnerable populations.

These high-risk groups include young children, older adults, and individuals with weakened immune systems.

For these individuals, Salmonella can cause severe dehydration, invasive infections (where the bacteria spread beyond the intestines), and other serious complications that may require hospitalization.

In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis and arthritis, the FDA said.

Scientists have identified a rare contagious skin cancer in brown bullhead catfish living in lakes across the US and Canada's Quebec, marking only the fourth known case of a naturally transmissible cancer in the animal kingdom.

A team led by the University of Vermont found that mysterious black skin lesions affecting brown bullhead catfish in Lake Memphremagog and other lakes in New England and Quebec were caused by a transmissible melanoma—the first such cancer ever identified in a freshwater fish species.

The findings, published in the journal Nature, add freshwater fish to a short list of species known to develop cancers that spread through the transfer of living cancer cells. Previously, transmissible cancers had been identified only in Tasmanian devils (facial tumor disease), dogs (canine transmissible venereal tumor), and shellfish, including clams, mussels, and other bivalve mollusks (leukemia-like transmissible cancers).

“The cancer cells behave more like parasites than conventional tumors, moving from fish to fish,” said the researchers led by the University of Vermont.

"The discovery sheds light on how cancer can spread in the wild and raises important questions about where this cancer originated, how it will affect fish health and populations—and how cancer works in all animals including humans," they added.

How Was Cancer Identified In Fish?

Since 2012, anglers and biologists have reported increasing numbers of brown bullhead catfish with raised black skin patches in Lake Memphremagog, which straddles Vermont and Quebec. By 2014, nearly one in three fish examined had developed the dark lesions.

Initially, researchers believed the disease might be caused by a virus. They later suspected pollution or another environmental pathogen. However, further investigation revealed that the lesions were actually melanoma.

“This was surprising, and we wanted to know how a bottom-dwelling fish was getting a cancer we associate with exposure to too much sunlight,” said Julie Dragon, a scientist at the University of Vermont.

Using whole-genome sequencing, the team identified hundreds of thousands of shared genetic variants among tumor samples that were absent from the host fish, confirming that the cancer spreads between animals through living cancer cells.

How Does The Cancer Spread?

Researchers are now trying to determine exactly how the cancer moves from one fish to another. They believe that the tumors appear only "in larger fish that are of spawning age".

Mark Henderson, a fish biologist and study co-leader in UVM’s Rubenstein School of Environment and Natural Resources said that it “maybe some part of spawning behavior leads to the spreading of the cancer between animals."

During spawning, brown bullhead gather closely in shallow water, allowing physical contact that could transfer tumor cells. Because the fish lack scales and spend much of their time on lake bottoms, scientists also believe sediments could harbor free-floating cancer cells.

The study also suggests that naturally occurring arsenic or hormonal changes may weaken the fish's immune system, making them more susceptible to infection.

Should Humans Worry?

Despite the unusual discovery, researchers stress that there is no known risk to humans.

Lake Memphremagog supplies drinking water to more than 175,000 people, but scientists say the cancer cells cannot infect or survive in another species. They also state that the fish are safe to handle for research and monitoring.

Fish remains a highly nutritious food, rich in high-quality protein, vitamin D, and omega-3 fatty acids that support heart and brain health.

Quebec's Ministry of the Environment recommends not eating fish with tumors, even though there is no evidence that doing so poses a risk to human health.

The findings raise broader questions about how pollution, habitat stress, and climate change may influence the evolution and spread of diseases in wildlife.

Researchers have developed an ultrasensitive blood test that can detect biological signs of Sjögren’s disease more than a decade before symptoms appear, potentially paving the way for earlier treatment and precision medicine.

Published in The Lancet Rheumatology, the researchers found that elevated levels of interferon-alpha (IFN-α), a key immune signaling protein, can be detected in the blood up to 14 years before a clinical diagnosis of Sjögren’s disease.

Importance Of Early Diagnosis

Observed every year on July 23, Sjögren’s Disease Day raises awareness about a chronic autoimmune disease that often goes undiagnosed for years because its symptoms, including dry eyes, dry mouth, fatigue, and joint pain, can mimic other conditions.

Diagnosis often takes years, by then damage to the salivary glands, tear glands, nerves, lungs, or kidneys already happens, making recovery impossible.

The newly developed blood test could change that by identifying people at risk long before symptoms begin. This could allow doctors to monitor patients closely and begin treatment earlier.

How Was The Study Conducted?

The researchers analyzed blood samples from:

• 177 people with Sjögren’s disease enrolled in the UK Primary Sjögren’s Syndrome Registry.
• More than 47,000 participants from the UK Biobank, including 257 people who later developed Sjögren’s disease.

Using an ultrasensitive single-molecule blood test, they measured interferon-alpha, a protein produced by the immune system during inflammation. The findings showed:

• About 61% of patients with Sjögren’s disease had significantly elevated IFN-α levels.
• Distinct immune protein "fingerprints" linked to IFN-α were detectable up to 14 years before diagnosis.
• People with high IFN-α formed a biologically distinct subgroup, despite having symptoms similar to other patients.
• Mouse experiments further suggested that persistently elevated IFN-α can drive immune changes associated with the disease.

The researchers believe the test could help doctors identify which patients are most likely to benefit from therapies that specifically target interferon-driven inflammation.

Professor David Hunt, from the University of Edinburgh, said, "Sjögren's disease is a debilitating condition which is often overlooked. We are delighted to have shown how precision medicine technologies can be used in Sjögren's disease to help decode the immune pathways which cause disease. We hope that this is an important step towards making our ultrasensitive IFN-α blood test available to people affected by this condition."

Professor Rayk Behrendt, from University Hospital Bonn, added, "Now, for the first time, we can take treatments geared toward suppressing the interferon effect and trial them specifically on patients with elevated interferon levels. We might also find new approaches to treatment that will help a large percentage of patients over the long term."

What Is Sjögren’s Disease?

Sjögren’s disease is a chronic autoimmune disorder in which the immune system attacks the body's moisture-producing glands, particularly those that make tears and saliva.

Although dry eyes and dry mouth are the primary symptoms, the disease can also affect the joints, lungs, kidneys, nervous system, and other organs. Around 90% of patients are women, and diagnosis is often delayed because symptoms overlap with those of many other illnesses.

Researchers say the findings mark a major step toward earlier diagnosis and precision medicine for Sjögren’s disease, offering hope that future patients may receive treatment years before irreversible organ damage develops.
