The flu is a common respiratory illness caused by the influenza virus. While it usually resolves on its own, the flu can sometimes lead to life-threatening complications, especially in high-risk individuals such as the elderly, pregnant women, and those with weakened immune systems or chronic medical conditions. The decision to hospitalize for the flu depends on several factors, including the severity of symptoms, the presence of underlying health conditions, and the patient's risk factors. Hospitalization may be necessary if the patient experiences severe symptoms such as high fever, difficulty breathing, confusion, persistent vomiting, decreased urination indicating dehydration, or other warning signs that require immediate medical attention.

When to seek emergency care for flu
The flu is a common illness that, in some cases, can lead to life-threatening complications. While it is not usually an emergency, certain groups are at a higher risk of developing severe complications. These groups include people over 65, pregnant women, those with weakened immune systems, and those with chronic conditions such as asthma, COPD, diabetes, or heart disease.
If you fall into one of these high-risk categories and are experiencing severe flu symptoms such as fever, chills, and body aches, you should seek emergency care. Additionally, if you are experiencing any symptoms that indicate a more serious condition, such as lung inflammation or severe dehydration, you should also go to the emergency room. These symptoms include difficulty breathing, shortness of breath, high fever that does not respond to over-the-counter medications, and confusion.
For otherwise healthy individuals, the flu is typically not an emergency. It is recommended to stay at home, get plenty of rest, and drink fluids. Over-the-counter medications can help manage symptoms. However, if your symptoms are not improving or you are concerned, you should contact your primary care doctor or visit an urgent care center.
It is important to remember that the flu is highly contagious, and you may spread it to others even if your symptoms are mild. To prevent the flu, it is recommended to get vaccinated annually and practice good hygiene, such as frequent handwashing and covering your mouth when coughing or sneezing.

Risk factors for flu complications
The flu can be a serious illness with life-threatening complications. While it is not usually an emergency for young and otherwise healthy people, certain groups are at a higher risk of developing severe flu complications. These groups include:
People with chronic conditions
Those with chronic lung disease (e.g., COPD, cystic fibrosis), neurologic and neurodevelopmental conditions, blood disorders (e.g., sickle cell disease), endocrine disorders (e.g., diabetes mellitus), and heart disease (e.g., congenital heart disease) are at a higher risk of flu complications. During recent flu seasons, 9 out of 10 people hospitalized with the flu had at least one underlying health condition.
Pregnant women
Pregnant women are at an increased risk of severe flu complications and may require immediate medical attention.
People over 65
Older adults, especially those over 65, are more susceptible to severe flu complications and may need hospitalization.
Individuals with weakened immune systems
People with weakened immune systems, such as those battling chronic conditions or immunocompromised individuals, are at a higher risk of flu-related complications.
Young children
All children younger than five years old, especially those under two, are at a higher risk of serious flu complications. The highest hospitalization and death rates are among infants younger than six months old.
Smokers and vapers
People who smoke or vape are at a significantly higher risk of developing flu-related complications, even if they are otherwise healthy.

Flu symptoms that require hospitalisation
The flu is a common illness, but it can lead to life-threatening complications. While most healthy individuals can manage the flu at home, certain groups are at a higher risk of severe complications and may require hospitalisation. These groups include people over 65, pregnant women, those with weakened immune systems, and individuals with chronic conditions.
If you fall into any of these high-risk categories and experience flu symptoms, you should seek medical advice promptly. The flu symptoms that may require hospitalisation include:
- Persistent vomiting that prevents the consumption of water
- Decreased urination indicating dehydration
- High fever that does not respond to over-the-counter medications
- Shortness of breath or difficulty breathing
- Confusion or difficulty thinking clearly
- Inability to eat or drink fluids
- Inability to get to the bathroom
- Lung inflammation
- Severe dehydration requiring intravenous (IV) fluids
Additionally, the flu can worsen existing chronic health conditions or trigger new illnesses, such as pneumonia, bronchitis, myocarditis, encephalitis, myositis, rhabdomyolysis, and sepsis. If you experience any of these complications, seek immediate medical attention.
It is always better to err on the side of caution. If you are concerned about your symptoms or feel extremely unwell, do not hesitate to seek medical advice or visit the emergency room.

Preventing flu-related hospitalisations
Flu can be a serious illness that can lead to life-threatening complications and even death. While it is usually not an emergency for young and otherwise healthy people, certain groups are at a higher risk of severe complications. These include people over 65, pregnant women, people with chronic conditions, weakened immune systems, and people who smoke or vape. For these high-risk individuals, the flu can become life-threatening, requiring immediate medical attention and even hospitalisation.
To prevent flu-related hospitalisations, it is important to take preventive measures to reduce the spread of the virus and lower the risk of severe illness. Here are some strategies to consider:
Get a Flu Vaccine
The single best thing you can do to prevent the flu is to get a flu shot. Vaccination is important for everyone aged 6 months and older, but it is especially crucial for those at higher risk of developing serious flu complications. This includes young children, pregnant women, people with certain chronic health conditions like asthma, diabetes, heart or lung disease, and people 65 years and older. Vaccination can reduce the risk of getting sick with the flu and lower the chances of flu-associated hospitalisation.
Practice Good Hygiene
In addition to vaccination, it is important to practice good hygiene to reduce the spread of germs. This includes frequent and thorough handwashing with soap and water, especially after coughing, sneezing, or blowing your nose. If soap and water are not available, use an alcohol-based hand sanitiser. Avoid touching your eyes, nose, and mouth, as germs spread this way. Cover your mouth and nose with a tissue when you cough or sneeze, and dispose of used tissues in a bin.
Wear a Mask
Wearing a mask can help protect you from breathing in infectious particles and reduce the spread of the virus to others. Masks are especially important in crowded or poorly ventilated spaces and when in close contact with others.
Stay Home if Sick
If you are sick, stay home and limit contact with others. This helps prevent the spread of the virus and gives your body time to rest and recover. Ideally, you should stay home for at least 24 hours after your fever subsides and your symptoms improve. Drink plenty of fluids to stay hydrated and help soothe a sore throat.
Seek Early Medical Attention
If you are in a high-risk group and develop flu symptoms, don't hesitate to seek medical attention early. Prompt treatment with antiviral drugs can make flu illness milder, shorten the duration of illness, and prevent serious complications that could lead to hospitalisation.
By following these preventive measures, you can help reduce the risk of flu-related hospitalisations and protect yourself and others from the potentially serious complications of the flu.

Treatment options for severe flu
Flu is a common illness caused by the influenza virus. While it is usually not a cause for concern, it can lead to life-threatening complications in certain high-risk groups. These groups include people over 65, pregnant women, those with underlying health conditions, and those with weakened immune systems. For these individuals, the flu can become severe enough to require hospitalization.
So, when is the flu severe enough to warrant a trip to the emergency room or hospital stay? Generally, if you are experiencing severe flu symptoms like fever, chills, and body aches, and you belong to a high-risk group, you should not hesitate to seek emergency medical attention. Additionally, there are several warning signs that indicate the need for immediate medical care. These include severe flu symptoms that cause significant responses in the body, such as lung inflammation, which makes breathing difficult, or severe dehydration that requires intravenous (IV) fluids. The flu can also worsen existing chronic health conditions or trigger new illnesses, such as pneumonia, bronchitis, inflammation of the heart, brain, or muscles, and sepsis. If you are experiencing any of these complications, it is crucial to seek medical help immediately.
If you are otherwise healthy and have mild flu symptoms, you may not need to go to the hospital. Instead, you can manage your symptoms with over-the-counter medications, bed rest, and staying well-hydrated. It is important to stay at home and avoid contact with others to prevent the spread of the virus. However, if your symptoms persist or worsen, it is advisable to see your primary care doctor or visit an urgent care center.
For those with severe flu symptoms or who belong to high-risk groups, there are treatment options available. Antiviral medications can be prescribed by a doctor to lessen symptoms and shorten the duration of the illness. These drugs work best when started within two days of the onset of symptoms and can also help reduce the risk of flu complications. However, it is important to carefully consider the side effects, which can range from mild reactions to severe allergic responses. In a hospital setting, close monitoring of breathing and oxygen levels, as well as the administration of IV fluids, can be crucial components of treatment for severe flu.
