Who is at Risk for Flu-Related Complications?
Influenza (flu) viruses can infect individuals of all backgrounds, but certain populations face a higher risk of experiencing severe complications.
Individuals who are at high risk for the flu, resulting in severe symptoms that may require hospitalization or even lead to death, should prioritize getting seasonal flu vaccinations as a preventive measure against infection.
Influenza High-Risk Groups
The information provided here highlights different groups that are at a higher risk for complications related to the flu. These include:
Elderly individuals are particularly vulnerable to complications from the flu due to changes in their immune system that come with age. People with chronic health conditions such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, heart disease, neurologic or neurodevelopmental conditions like stroke, endocrine disorders such as diabetes, and weakened immune systems due to diseases or medications also face an increased risk of flu complications.
Pregnant individuals are at a higher risk of severe illness from the flu because pregnancy affects their immune system and respiratory function. Additionally, changes in the cardiovascular and immune systems during pregnancy can make pregnant individuals more susceptible to severe respiratory illnesses like influenza.
Children under 5 years old are more likely to experience severe symptoms if they get the flu. Even healthy children in this age group are at a higher risk because their immune systems are still developing. It is crucial to protect children by ensuring they receive flu vaccinations. Immunizing those around children also plays a significant role in preventing the spread of the flu.
Respiratory diseases further increase the risk of complications from the flu. Individuals with chronic lung diseases like asthma and COPD may experience worsened symptoms and have a higher chance of developing pneumonia when infected with the flu.
What Causes Flu?
Flu, also known as influenza, is caused by Type A and Type B influenza viruses. Type A viruses often come from animals and then spread to humans. The flu is a highly contagious respiratory disease that affects millions of people worldwide each year.
These viruses primarily spread through droplets in the air when infected individuals cough, sneeze, or talk. Another way to contract the flu is by touching surfaces that are contaminated with the virus and then touching your eyes, mouth, or nose.
Symptoms to Look Out For
Symptoms of influenza can include:
Influenza is caused by a highly contagious respiratory virus. It can affect people of all ages, but there are certain individuals who are at a higher risk of developing complications from the flu. These high-risk groups include children under 5 years old, especially those under 2, adults over 64 years old, people staying in long-term care facilities, American Indian or Alaska Native people, and women who are pregnant or have given birth in the last 2 weeks.
In addition, individuals with certain health conditions face an increased risk of complications from the flu. These conditions include chronic lung diseases such as asthma, COPD (chronic obstructive pulmonary disease), and cystic fibrosis; heart diseases like congestive heart failure and coronary artery disease; neurologic or neurodevelopmental conditions such as stroke; endocrine disorders like diabetes; and weakened immune systems due to disease or medications.
It is important for individuals in these high-risk groups to seek medical attention if they experience symptoms of influenza. Getting a prompt diagnosis and treatment can help prevent serious complications associated with the flu. Additionally, it is recommended that these individuals get vaccinated, as it can provide protection against the virus and reduce the risk of flu-related complications.
Possible Flu Complications
Complications from the flu can include pneumonia, bronchitis, sinusitis, ear infections, and myocarditis. These complications can occur in individuals who are at higher risk due to various health conditions.
Health conditions that increase the risk of flu complications include chronic lung diseases like asthma, COPD, and cystic fibrosis, as well as heart disease including congestive heart failure and coronary artery disease. Neurologic or neurodevelopmental conditions such as stroke, endocrine disorders like diabetes, and weakened immune systems due to disease or medications also put individuals at higher risk.
Certain metabolic disorders, kidney disease, and liver disease can also make individuals more prone to severe flu-related complications. It is important for people with these health conditions to follow CDC sick day guidelines and get an annual flu vaccination.
Pregnant women are at an increased risk of complications such as premature labor and delivery. Young children under 5 years old are more susceptible to severe complications like pneumonia. Older adults also have a higher risk of developing complications and may need to be hospitalized. Immunocompromised individuals, including cancer patients undergoing treatment, are also at higher risk for severe flu-related complications.
It is crucial for individuals with these health conditions to take preventive measures, such as getting vaccinated against the flu each year and practicing good hygiene habits, to reduce their risk of experiencing influenza-related complications.
Emergency Warning Signs of Complications

Treatment
Treatment options for the flu include antiviral drugs, which are prescription medications that work best when started within one to two days of getting sick. These medications come in various forms like pills, liquid, inhaled powder, or intravenous solutions, and can only be obtained with a healthcare provider’s prescription.
Research has shown that antiviral drugs are most effective if taken within two days of becoming ill. However, they can still be helpful even if treatment begins later, especially for individuals at high risk or those who are hospitalized.
Individuals with chronic health conditions such as pulmonary disease (like asthma or COPD), coronary artery disease, or those on long-term aspirin therapy should consider antiviral treatment. These drugs can make the illness less severe and shorten its duration.
Early treatment with antivirals can also help prevent serious flu complications like pneumonia. However, it is important to note that not all otherwise healthy individuals with the flu need to be treated with these medications.
When taking antiviral drugs, it is crucial to follow the instructions provided by your healthcare provider. These medications can effectively reduce symptoms and prevent complications associated with respiratory illnesses caused by the flu virus.
Flu vs. COVID-19
When we compare the transmission of COVID-19 and the flu, it is clear that both viruses spread through close contact and poorly ventilated indoor spaces. They primarily spread through respiratory droplets released when an infected person talks, sneezes, or coughs. They can also spread by touching surfaces contaminated with the virus and then touching the face.
While there are similarities in how they spread, there are also notable differences between the flu and COVID-19.
Both COVID-19 and influenza can be prevented through vaccination. Annual flu vaccines are available for protection against different strains of influenza viruses. Vaccines authorized for prevention and reducing severity have been developed for COVID-19 as well.
To reduce the risk of infection from both viruses, it is recommended to maintain distance from sick individuals in indoor public spaces, avoid crowded places with poor ventilation, and practice good hand hygiene by washing hands frequently or using hand sanitizer when soap and water are not available. Wearing well-fitting masks in high-risk areas with a high number of COVID-19 cases can also provide additional protection.
Cold vs. Flu
Differentiating between symptoms of a cold and the flu is really important in order to accurately diagnose and manage the illness. Knowing the differences can help people make informed decisions about their health. Here are some key points to consider:
Symptoms of a Cold
Symptoms of the Flu
It is important to distinguish between these two illnesses because certain groups of people are at higher risk for flu-related complications.
Preventing the Flu
Preventing the flu is all about taking the right steps to keep yourself healthy. One of the most important things you can do is get vaccinated. This helps protect you from getting the flu and reduces the risk of complications. Along with vaccination, there are other preventive measures you can take.
To effectively prevent the spread of the flu and protect yourself from potential complications, it is important to follow recommended preventive measures. This includes getting vaccinated every year, washing your hands frequently or using hand sanitizers when soap and water are not available, covering your coughs and sneezes with tissues or your elbows, avoiding touching your face, and keeping your distance from sick people.
Why Getting a Flu Shot Matters
Preventing the flu is crucial, and one way to do so is by getting a flu shot. The flu shot is important because it significantly reduces the risk of flu-related complications. Certain groups, such as children under 5 (especially those under 2), adults over 64, individuals in long-term care facilities, American Indian or Alaska Native people, and pregnant women or those who have recently given birth, are especially vulnerable to these complications during flu season.
In addition, there are specific health conditions that increase the risk of flu-related complications. These conditions include chronic lung disease (such as asthma and COPD), heart disease (including congestive heart failure and coronary artery disease), neurologic or neurodevelopmental conditions (like stroke), endocrine disorders (such as diabetes), and weakened immune systems due to diseases or medications.
It is worth noting that even healthy children are at a higher risk for flu-related complications due to their age. That’s why it is crucial to immunize children against influenza and ensure that the people around them are also vaccinated. Moreover, older adults are more susceptible to severe illness from the flu due to age-related changes in immune function.
Getting a yearly flu shot is essential for individuals at a higher risk of experiencing complications associated with influenza. By getting vaccinated ourselves and encouraging those around us to do the same, we can help minimize the impact of the virus during each flu season. It is also important to remember that influenza is among the leading causes of death for children, highlighting the need for vaccination in this vulnerable group.
What Happens if Flu is Not Treated?
When flu is left untreated, it can cause severe illness and even life-threatening consequences, especially for vulnerable populations. The flu virus can lead to various complications that affect different parts of the body. For example, people with the flu may experience symptoms like a sore throat and ear infections, which can be quite distressing and uncomfortable.
Certain groups of people are at a higher risk of developing severe complications from the flu. Those with underlying health conditions such as congestive heart failure and lung disease have weakened immune systems, making it harder for them to fight off the infection effectively.
It is crucial for healthcare providers to identify these high-risk groups and provide appropriate care and interventions. Prompt treatment of influenza with antiviral medications can help alleviate symptoms and reduce the risk of complications in vulnerable populations.
Controlling the Spread of Infection
Controlling the spread of infection is incredibly important in reducing the risk of flu complications. The flu virus spreads easily through respiratory droplets when an infected person coughs, sneezes, or talks. So, it is crucial to implement effective infection control measures to prevent the transmission of the virus and protect individuals who are at a higher risk for flu-related complications.
To control the spread of the flu virus, vaccination is key. Getting vaccinated against the flu is one of the most effective ways to prevent infection. It is recommended for everyone aged 6 months and older, especially for those who are at higher risk.
Practicing good personal hygiene is also essential. Washing hands frequently with soap and water or using alcohol-based hand sanitizers can help reduce the transmission of the virus.
Respiratory etiquette is another important measure. Covering your mouth and nose with a tissue or your elbow when coughing or sneezing can prevent respiratory droplets from spreading to others.
In addition, it is important to avoid close contact with individuals who have flu symptoms. Limiting close contact can minimize exposure to the virus.
If someone develops flu symptoms, seeking prompt medical care is crucial. Healthcare professionals may prescribe antiviral medications, which can be used to treat influenza and reduce its severity if taken within 48 hours after symptom onset. These medications are particularly important for individuals at higher risk for complications as they may help prevent serious illness and hospitalization.
Prevention Before and During Travel
Preventing the flu before and during travel involves taking effective measures to control the spread of the virus. It is important to consider these measures, especially for individuals who are at a higher risk of flu-related complications.
To prevent flu transmission while traveling, it is recommended to:
