Lone Star Tick disease: Scientists have verified the first known death tied to a serious meat allergy brought on by a tick bite. The man, who passed away in 2024 after eating a burger, had alpha-gal syndrome. This condition begins after certain tick bites and leads to dangerous allergic reactions to red meat and other foods made from animals. Two weeks before his death, he had already reacted badly after eating a steak.
“The sad part is that no one recognised that earlier incident as anaphylaxis, so it was never linked to the beef,” said study co-author Thomas Platts-Mills, an allergist at the University of Virginia School of Medicine who helped identify alpha-gal syndrome and diagnosed the New Jersey case, during an interview with NBC News. But how did he develop this condition in the first place?

A tick marked with a small white dot is known as the lone star tick (Amblyomma americanum). Many people already know that certain tick species can threaten human health. Lone star ticks are mainly found in Texas and Oklahoma, stretching across the Southern states and moving up the Atlantic coastline to parts of Maine. They live in wooded regions and are most common from April to September.
Falling ill after a lone star tick bite can take several days or even a few weeks. A bite can trigger various problems, including a serious meat allergy known as alpha-gal syndrome.

Bites from lone star ticks can lead to another major effect. The bite can cause the body to develop an allergy to meat. Substances from the tick, including alpha-gal, enter the bloodstream when it bites, which alerts the immune system and prompts the body to create antibodies to the alpha-gal molecule. Humans do not naturally produce this sugar, so the body treats it as foreign.
This reaction can make a person allergic to the sugar. Alpha-gal is present in many common foods, including beef, pork, lamb, dairy products, and gelatin. Once the allergy develops, a person can fall sick after eating these foods.
Experts believe that many people with alpha-gal syndrome have no idea they carry it. In the New Jersey case, it took scientists months to confirm that the man had the syndrome and had died as a result of it. Warmer winters have also allowed ticks to remain active for longer periods, raising the chances of bites throughout the year.
Anyone who thinks they may have this allergy can undergo testing to check. Although there is no cure for alpha-gal syndrome, doctors advise people with the condition to avoid all forms of meat, as well as dairy, gelatin, and some medicines that include these ingredients.
Many people never realise they were bitten, unless a rash becomes visible. The symptoms of alpha-gal syndrome vary widely and may take weeks to appear, which makes it difficult to diagnose.
Signs of an alpha-gal allergy can include gastrointestinal discomfort after eating foods such as:
Other signs may involve hives or, in severe situations, anaphylaxis. The allergy can take four to six weeks to form after the tick bite. Reactions may also be delayed for several hours after a person eats the food that triggers it.
A healthcare professional can test for the alpha-gal IgE antibody through a blood sample. Food challenge tests may also be carried out under medical supervision, in case a severe reaction occurs.

The NHS has released fresh guidance on how to manage flu symptoms, setting out four simple steps that could help people recover faster. Influenza, commonly known as flu, is a highly contagious viral illness that affects the respiratory system, including the nose, throat, and lungs. It is marked by a sudden onset of fever, muscle aches, headaches, a persistent dry cough, and extreme tiredness, making it far more serious than the common cold.
Recent data from NHS England shows that in the first week of January, an average of 2,924 hospital beds across England were taken up by patients with flu. This figure reflects a nine per cent increase compared with the previous week.
With flu cases continuing to climb, the NHS has shared several important steps that people can follow to help support a quicker recovery.
In a recent update, NHS England warned that social gatherings during Christmas and New Year may have led to a resurgence of winter illnesses. NHS national medical director Professor Meghana Pandit said: “It is clear that the pressure on the NHS this winter is far from easing, with hospitals once again seeing a rise in patients admitted with flu and other respiratory viruses last week.
“The colder weather is also bringing more vulnerable patients to A&E with breathing difficulties, along with an increase in injuries caused by slips and falls in icy conditions, making this an exceptionally demanding period.”
According to the Mirror, she added: “Staff continue to work extremely hard, with teams across the country doing everything possible to ensure patients receive the care they need. It remains important for people to seek care as usual, and there are still many opportunities to get vaccinated and protect yourself against flu.”
The NHS says flu symptoms tend to appear suddenly and may include:
Children may experience similar symptoms, but they can also have earaches and may appear more tired or less active than usual.
The NHS states: “If you have flu, there are steps you can take to help yourself recover more quickly.”
You should contact NHS 111 or arrange an urgent GP appointment if you or your child have flu symptoms and:

Cipla, a global name in inhalation therapies, has announced the launch of Afrezza, the world’s only rapid-acting inhaled insulin, in India. The drug is approved for adults with type 1 and type 2 diabetes to help manage high blood sugar levels and represents a notable change in how insulin can be delivered in a country facing a growing diabetes crisis.
For many patients, injecting insulin during long workdays or in public spaces can be uncomfortable or inconvenient. While insulin injections are widely used, awareness around inhaled insulin remains limited. Below, we explain how inhaled insulin works and what it means for people living with diabetes.
Inhaled insulin is a fast-acting form of insulin that is taken as a fine powder through an inhaler. Instead of being injected, it is breathed into the lungs, where it is quickly absorbed into the bloodstream to manage blood sugar spikes that occur after meals. This makes it a needle-free option for adults with type 1 or type 2 diabetes.
It begins working very rapidly, often just before or at the start of a meal, and exits the body sooner than injectable insulin. Because of this, it may lower the risk of insulin stacking and offers greater flexibility around mealtimes. Afrezza is currently the main FDA-approved inhaled insulin available.
The insulin comes as a dry powder and is taken using a small, discreet inhaler with single-use cartridges available in 4, 8, and 12-unit doses. It has been approved by the FDA for adults with type 1 and type 2 diabetes to help control blood sugar rises after meals. “Its absorption into the bloodstream is faster than injectable rapid-acting insulins such as lispro or aspart,” said Dr Hetashvi Gondaliya, as reported by The Indian Express.
Before starting inhaled insulin, patients are required to undergo lung function tests. The insulin itself is identical to the insulin used in injections. What differs is the way it enters the body.
In simple terms, the insulin is not new, only the method of delivery is. Once inhaled, it is absorbed through the lungs, passes into the bloodstream, and helps control the rise in blood sugar levels that happens after eating.
Inhaled insulin is not necessarily better for everyone, but it offers an alternative to injections. It works faster to control post-meal blood sugar levels and may appeal to people who dislike needles. However, it is less efficient than injected insulin, requires a specific inhaler, and is not suitable for all patients.
Studies show that blood sugar control is similar to injectable insulin, but inhaled insulin must still be used along with long-acting basal insulin. It is best viewed as an option rather than a replacement.
According to the National Institutes of Health, inhaled insulin is not appropriate for everyone. It may be considered for adults with type 1 or type 2 diabetes who want a needle-free option or need rapid control of blood sugar after meals.
However, it is not recommended for people who smoke or have smoked in the past six months, or for those with lung conditions such as asthma, COPD, or bronchitis. It is also not approved for children or pregnant women. Lung health and ongoing insulin needs must be carefully evaluated before starting this treatment.
Always consult your doctor before switching to or starting inhaled insulin. Your healthcare provider can help determine whether it is safe and suitable for you based on your medical history and lung health.

People should be aware of a rare and unpredictable condition called SCAD. Spontaneous coronary artery dissection occurs when the inner layers of a coronary artery split away from the outer wall. When this happens, blood can leak into the space between the layers, leading to clot formation. If these clots grow large enough, they can block blood flow to the heart and cause a heart attack.
Doctors are still struggling to fully understand this condition. The cause remains unknown, and it often strikes suddenly in people who do not have the usual risk factors linked to heart disease. SCAD is most commonly seen in women between the ages of 45 and 53, although it can affect people of any age or gender.
SCAD is an acronym that can refer to different things, but it is most widely used to describe Spontaneous Coronary Artery Dissection. This is a serious heart condition in which a tear forms in one of the arteries supplying blood to the heart, potentially triggering a heart attack. SCAD is also the name of the Savannah College of Art and Design, a well-known creative university in the United States, and an Indian NGO working in the field of social change and development.
According to the British Heart Foundation, SCAD is a condition that “can’t currently be predicted or prevented.” The charity stresses the importance of seeking medical help if symptoms appear, so the condition can be identified as early as possible. Many of the warning signs are similar to those of angina or a heart attack, which can make it difficult to recognise.
The symptoms of SCAD often resemble those associated with angina or a heart attack. These may include:
The British Heart Foundation advises anyone experiencing chest pain or these symptoms to call 999 straight away. One of the dangers of SCAD is that people may dismiss the symptoms, believing they are not at risk of a heart attack. Experts say the condition cannot be predicted or prevented.
Neck pain can sometimes be linked to arterial dissections, which involve a tear in blood vessels supplying vital organs. In such cases, the pain is often sudden, severe, and felt on one side of the neck. It may appear on its own or develop before more serious symptoms, such as those associated with a stroke or heart-related event.
The pain occurs due to damage to the artery wall and should always be treated as a medical emergency. While neck pain is commonly associated with muscle strain, experts warn that, in rare cases, it can signal a much more serious underlying problem.
According to the American Heart Association, neck pain related to arterial dissection may present in the following ways:
Around 80 percent of people diagnosed with SCAD are women, and the condition is known to occur during pregnancy or shortly after childbirth. Because it develops without warning, SCAD is often discovered only after a major medical event, such as a heart attack.
Treatment depends on the severity of the condition. Some patients are managed with medication to reduce the risk of blood clots, while others may require stents to keep the artery open. In rare cases, coronary artery bypass surgery is needed to restore blood flow.
The British Heart Foundation notes that receiving a SCAD diagnosis can be deeply unsettling, especially when it follows an emergency. Many patients report feeling isolated, largely because the condition is so rare and not widely understood.
