The Italian medical authorities are on high alert after the appearance of the first case of the Australian flu, caused by the H3N2 virus, which not only affects the lungs, but can also affect the heart and brain. Doctors draw attention to the high risk of neurological complications associated with this virus, with symptoms that can vary from dizziness and confusional states to severe encephalitis.
The first European case was registered in Italy, where the virus began to spread in the regions of Lombardy, Piedmont, Lazio, and even in Genoa and other areas of Liguria. This strain of influenza A is recognized for the additional health risks, not only for the lungs, but also for the central nervous system and other vital organs, such as the heart and brain.
Concerns about potential neurological complications were also intensified in Genoa and the rest of Liguria, after Professor Matteo Bassetti, a renowned expert in infectious diseases, reported the case of a 76-year-old man admitted to the San Martino hospital in Genoa. According to the professor’s statements, the patient could not even recognize his own wife, and among the first symptoms he mentioned was the loss of taste, which affected his ability to feel the taste of food during meals.
This flu, already described as a major public health risk, worries experts because of its unusual symptoms and the potential to severely affect neurological functions. Doctors call for increased vigilance and rigorous preventive measures to limit the spread of the virus. These measures are extremely important, especially since several cases of infection with the A/H3N2 influenza virus have already been reported, associated with encephalitis, convulsions and meningoencephalitis, while, in the case of children, febrile convulsions have been reported.
What is H3N2 flu?
The H3N2 flu is a strain of the influenza A virus, known for causing severe seasonal epidemics, especially in the cold season. Also known as the “Australian flu” due to the large number of cases initially reported in Australia, this strain differs from other types of flu by the severe complications it can cause, especially in vulnerable people, such as the elderly and those with medical conditions chronic.
The H3N2 virus has a rapid mutation rate, which means that the human body may have difficulty developing long-term immunity against it, even after seasonal vaccination. For this reason, circulating strains are included in the annual flu vaccine, which adapts its composition to include the most common variants of the flu virus each year.
Symptoms of H3N2 flu
Like other flu strains, H3N2 primarily affects the respiratory tract, causing classic flu symptoms, such as:
- high fever
- persistent cough
- pain in the throat
- headaches
- muscle and joint pains
- extreme fatigue
However, the H3N2 flu also has particularities that differentiate it, especially through the neurological manifestations that may appear. Among them are:
- dizziness
- mental confusion
- encephalitis, a serious inflammation of the brain
- loss of taste and smell
- Guillain-Barré syndrome (GBS), which affects the peripheral nervous system
- acute disseminated encephalomyelitis (ADEM), a rare but dangerous inflammation of the central nervous system.
Doctors in Italy have reported severe cases of neurological disorders associated with the H3N2 flu. For example, a 76-year-old patient, admitted to a hospital in Genoa, showed profound mental confusion, unable to even recognize his wife. This is one of the dangerous characteristics of this strain – the ability to affect the brain and cause cognitive and sensory disorders.
The risks and complications associated with the H3N2 flu
H3N2 is especially dangerous for vulnerable people, such as the elderly, children, pregnant women and people with chronic diseases (diabetes, cardiovascular diseases, asthma). Apart from the usual respiratory complications, such as pneumonia, this strain is associated with cardiac and neurological complications.
Studies show that H3N2 can trigger severe inflammation that leads to encephalitis, a type of brain inflammation that can affect memory and cognitive abilities. There are also reported cases of meningoencephalitis, which can cause convulsions and permanent neurological damage. In children, febrile convulsions are another frequent manifestation, which may require hospitalization.
Preventive measures
The annual flu vaccine is considered the best method of protection against severe complications of the H3N2 flu. It can reduce the severity of the disease and the risk of hospitalization, especially for the vulnerable categories. At the same time, hygiene measures such as frequent hand washing, avoiding crowds in the cold season and wearing a mask in closed spaces are recommended to reduce the risk of infection.
For infected people, isolation at home and avoiding contact with those around them are essential to prevent the spread of the virus.
Treatment and recovery
Treatment of H3N2 flu generally involves bed rest, proper hydration and the administration of symptomatic drugs, such as antipyretics and pain relievers. In severe cases, doctors may recommend antivirals, such as oseltamivir (Tamiflu) or zanamivir (Relenza), which can reduce the duration of symptoms and the risk of complications.
People who have neurological symptoms or severe complications must seek medical care immediately. Prompt treatment in the hospital can reduce the risk of permanent damage to the brain and nervous system.
The spread of the H3N2 flu in Europe is an alarm signal, especially because of the complications it can cause. Correct information and vaccination remain the best methods of preventing this disease.

The H3N2 Flu: The “Australian Flu” That’s Got Us All on the Edge of Our Seats!
So, have you heard about the latest guest to crash the European health party? It’s the H3N2 virus, affectionately dubbed the “Australian flu”—though let’s face it, who wants to associate a virus with a holiday destination known for its beautiful beaches and stunning landscapes? But here we are! Who knew that a virus could travel better than most of us during the holiday season?
In Italy, where the culinary delights are only overshadowed by the growing concern over flu complications, healthcare professionals have been wearing their serious hats after the first European case popped up like an unwelcome visitor at a dinner party. Hospitals in Lombardy, Piedmont, Lazio, and even Genoa are now on high alert, focusing not just on the lungs, but also on the heart and brain! Because, apparently, the flu thought it would challenge our entire vital organ lineup. Talk about overachieving!
But What Exactly Is This H3N2 Flu?
Imagine a flu strain so ambitious that it’s not content with just causing sore throats and runny noses! The H3N2 flu, part of the notoriously fickle influenza A family, has been making waves, causing seasonal epidemics and occasionally leading to serious health complications. Fun fact: it seems to thrive in cold weather—which is just fantastic news for anyone who thought winter was going to be dull. With rapid mutation rates that would make a chameleon blush, your body might as well throw in the towel on long-term immunity.
Symptoms of H3N2: Not Just Your Average Flu
Ah yes, the classic symptoms. High fever? Check. Persistent cough? Double-check. But wait! What’s that? Dizziness and mental confusion? Well, that’s a surprise twist in the plot. Not to mention the very unpopular loss of taste—at least the one silver lining here is that if you’re avoiding bad food, you might not even know it! But poor old ’76-year-old-who-can’t-recognize-his-wife’ certainly didn’t sign up for this, did he? Perhaps the flu thought it could just get away with aiming for a midlife crisis!
Time to Panic? Or Just Be Smart?
While authorities are raising alarms (and perhaps a few eyebrows), let’s not forget that preventative measures are our best friends. Just like our friendly neighborhood superhero, the flu vaccine swoops in to save the day by reducing severity—even if it seems like it’s always a year behind on figuring out what’s actually going around!
Proper hygiene, frequent hand washing, and general avoidance of human hordes during the chilly months? That’s basic flu etiquette! Is it too much to ask for people to wash their hands and avoid crowded places? You’d think after all these years, we’d become more civilized, but alas, here we are!
Treatment: It’s Not All Gloom and Doom!
If you do find yourself facing off against this cheeky little virus, the treatment recommendations involve your classic arsenal: bed rest, hydration, and the beloved symptomatic drugs that people swear by but also complain about not making them feel like superheroes fast enough. In some severe cases, antivirals like Tamiflu step in, like the dependable friend you didn’t know you needed!
So here’s the kicker: while H3N2 is, quite frankly, a nerve-wracking nuisance, with information and vaccinations playing leading roles in the health theater, we can still keep the curtain from falling! Just make sure you’re using the knowledge wisely—because nothing says “I care” like taking your flu prevention seriously.
So, folks, arm yourselves with knowledge, get that flu jab, and please—let’s all aim for fewer surprises in 2023!
Stay safe, stay healthy, and until next time, keep those hands clean and your mind sharp!
Some mind games. Unfortunately, this strain is proving to be particularly challenging, with symptoms that extend well beyond the typical cough and fever. It’s now making a case for itself as a neurological menace, with reports of encephalitis and Guillain-Barré Syndrome—something that would make any healthcare professional shudder.
Who’s at Risk?
Well, if you belong to any of the vulnerable groups, you might want to pay extra attention! The elderly, children, pregnant women, and those with chronic health conditions like diabetes and asthma are finding themselves on the front lines of this flu battle. The usual respiratory quirks are bad enough, but this H3N2 strain has a knack for turning those quirkiness into serious complications, including inflammation of the brain. Fun times, right?
Prevention: How to Dodge the Flu Bullet
So, how do you play defense against this crafty viral foe? The annual flu vaccine is your best bet. It’s like putting on a suit of armor before heading into battle. And while you’re at it, don’t forget the classic hygiene tips: wash those hands, avoid crowded places when the temperature dips, and consider wearing a mask in enclosed spaces. Your future self will thank you!
Treatment: When to Call in Reinforcements
If you find yourself in the unfortunate position of catching the H3N2 flu, don’t despair! Treatment generally involves bed rest, hydration, and over-the-counter medications to ease your symptoms. But if your symptoms take a dark turn toward neurological territory, it’s time to ring up your healthcare provider. Antiviral medications like Tamiflu or Relenza can help reduce both the severity and duration of your suffering—definitely worth considering if you land in the high-risk category.
