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

Amid reports of rare botulism cases in the UK, the country's Medicines and Healthcare products Regulatory Agency (MHRA) has issued a safety warning for all botulinum toxin type A products, including Botox and other cosmetic injectables.
The regulator said cases of iatrogenic botulism—botulism caused by medical treatment—have been reported following both therapeutic and cosmetic use of botulinum toxin products when the toxin spreads beyond the intended injection site.
"Patients should seek immediate medical advice if they experience signs and symptoms," the MHRA said.
Botulinum toxin medicines are widely used for cosmetic procedures, such as reducing facial wrinkles, as well as for treating conditions including muscle spasms, excessive sweating (hyperhidrosis), and an overactive bladder.
While these medicines are considered safe when used correctly, the MHRA warned that, in very rare cases, the toxin can spread beyond the injection site and cause botulism—a serious and potentially life-threatening condition.
To improve awareness, the regulator has worked with manufacturers to update product information and patient leaflets to more clearly highlight the risk of iatrogenic botulism.

The MHRA warned that symptoms may not appear immediately after treatment. They can develop within days or even up to four weeks after receiving a botulinum toxin injection.
Patients are advised to seek immediate medical attention if they experience:
According to the MHRA, the risk of serious side effects may be higher in:
Health officials say early recognition of symptoms is critical, as prompt treatment can help prevent serious complications.
"While botulism is a rare infection, it can be serious. There are effective treatments available, and we recommend seeking immediate medical advice if you have had a recent treatment and are experiencing symptoms such as difficulty swallowing," said Dr. Martin Bewley, Consultant in Health Protection at the UK Health Security Agency (UKHSA).
Dr. Alison Cave, Chief Safety Officer at the MHRA, recommended that healthcare professionals and patients be aware of the symptoms of botulism and act quickly if they arise. Importantly, the expert "strongly urged the public to avoid unlicensed products and seek treatment only from appropriately qualified practitioners."
Botulism is a rare but serious illness caused by a toxin produced by the bacterium Clostridium botulinum. The toxin attacks the nervous system and can lead to paralysis, breathing difficulties, and, in severe cases, death if not treated promptly.
Because it can rapidly affect the muscles involved in breathing, botulism is considered a medical emergency.

The US Food and Drug Administration (FDA) has approved a once-daily pill that can lower low-density lipoprotein (LDL), commonly known as "bad" cholesterol, a major risk factor for heart disease.
Developed by Merck, enlicitide, which will be marketed as Lipfendra, is the first FDA-approved oral PCSK9 inhibitor for reducing LDL cholesterol.
Lipfendra has been approved as an adjunct to diet and exercise to reduce LDL cholesterol in adults with primary hypercholesterolemia, including those with heterozygous familial hypercholesterolemia (HeFH).
The approval is based on two Phase 3 clinical trials showing that Lipfendra can reduce LDL cholesterol to 50–60 mg/dL or even lower in many patients.
"Results from these Phase 3 trials showed treatment with Lipfendra resulted in reductions across other atherogenic lipoproteins associated with atherosclerotic cardiovascular disease (ASCVD) risk, including non-high-density lipoprotein cholesterol (non-HDL-C) and apolipoprotein B (ApoB)," Merck said.
High LDL cholesterol is a major risk factor for atherosclerotic cardiovascular disease (ASCVD), the leading cause of death globally.
"In two Phase 3 trials, LIPFENDRA led to impressive reductions in LDL-C. Now, for the first time, patients have an oral PCSK9 inhibitor for LDL lowering," said Dr. Ann Marie Navar, lead author of the clinical trial and associate professor at the University of Texas Southwestern Medical Center.

Lipfendra is a 20 mg once-daily tablet that works by blocking PCSK9, a protein that regulates LDL receptors in the liver.
Normally, PCSK9 reduces the number of LDL receptors available to remove cholesterol from the bloodstream. By inhibiting this protein, Lipfendra allows more LDL receptors to remain active, enabling the liver to clear more LDL cholesterol from the blood.
Unlike statins, which lower cholesterol by blocking an enzyme the liver uses to produce cholesterol, Lipfendra targets the PCSK9 pathway. It is also the first oral medicine in this class, whereas existing PCSK9 inhibitors are administered as injections.
The FDA approval was supported by two Phase 3 studies, including a 24-week trial involving 2,912 participants, which demonstrated significant reductions in LDL cholesterol.
The studies found that:
The cholesterol-lowering effect was comparable to that seen with injectable PCSK9 inhibitors.
Merck is now conducting a cardiovascular outcomes trial to determine whether Lipfendra also lowers the risk of heart attacks, strokes and cardiovascular death, as injectable PCSK9 inhibitors have previously been shown to do.
Merck said Lipfendra will be available in the United States within the next few weeks. The company has set a list price of $315 for a 30-day supply, according to Merck spokeswoman Julie Cunningham.
Lipfendra is intended for adults with hypercholesterolemia, a condition characterized by elevated LDL cholesterol that can lead to plaque buildup in the arteries.

Breast cancer diagnosed shortly after pregnancy may be more aggressive. According to new research, some young mothers may face poorer outcomes despite having similar types of breast cancer tumors as other women.
A UCLA-led study, published in npj Breast Cancer, found that women diagnosed with hormone receptor-positive (HR+), HER2-negative breast cancer within the first three years after childbirth, especially during the first year, were more likely to have tumors with a higher risk of recurrence.
It therefore indicates that postpartum breast cancer is not simply breast cancer diagnosed after pregnancy but may be a biologically distinct disease.
Researchers analyzed young women with HR-positive, HER2-negative breast cancer using the widely used 21-gene Oncotype DX Recurrence Score, a genomic test that helps predict the likelihood of cancer recurrence and whether chemotherapy may be beneficial.
They discovered that tumors diagnosed during the first three years after childbirth had significantly higher recurrence rates than tumors in women who had never given birth.
The highest scores were observed among women diagnosed within the first year after delivery.
"Our findings suggest that the first three years after childbirth represent a distinct biological window during which hormone receptor-positive breast cancers may behave more aggressively," the researchers observed.
The study also provides one of the first genomic definitions of this high-risk postpartum period rather than relying solely on clinical observations.

Researchers believe that the answer to that question lies in what happens to the breast after breastfeeding comes to an end.
After pregnancy and lactation, the breast undergoes a natural process called mammary gland involution, during which the milk-producing tissue shrinks, and the breast returns to its pre-pregnancy state.
While this change is normal, it creates a temporary environment that features inflammation, weakened immune system, and extensive tissue restructuring.
According to a recent review published in Breast Cancer Research, these biological changes may unintentionally create conditions that help dormant cancer cells survive, grow, and spread. Researchers describe this postpartum remodeling as a "tumor-promoting microenvironment."
These processes may partly explain why postpartum breast cancers are often diagnosed at more advanced stages and have poorer outcomes than breast cancers in women of similar age who have not recently given birth.
The findings hold importance as breast cancer rates among younger women continue to increase worldwide just when women are getting pregnant later in their lives. Previous studies have indicated that breast cancer detected after pregnancy behaves differently.
"The medical community has long recognized that breast cancers diagnosed after pregnancy can behave differently," UCLA researchers said. "With breast cancer rates among younger women increasing, scientists have been studying whether delayed timing of first pregnancy may help explain some of that trend."
Because pregnancy and breastfeeding naturally change breast tissue, warning signs like lumps or breast firmness can sometimes be mistaken for normal postpartum changes. This may delay diagnosis and allow cancers to progress before they are detected.
