The death of Taiwanese actress Big S (Xu Xiyuan) from severe influenza during the peak winter season has shocked the region,serving as a stark reminder of the potentially fatal consequences of this frequently enough-underestimated illness. Critical care doctor Huang XuanS public warning highlights the devastating long-term effects that can result from severe influenza, even after recovery.
Dr. Huang, in a recent Facebook post, urged the public to take severe influenza seriously, emphasizing that even after recovery, patients may suffer from lasting health problems due to organ damage. He stated that severe cases, such as those involving pneumonia or encephalitis, can significantly increase the risk of developing chronic diseases.
Peak Influenza Season: Four Terrifying Sequelae
Dr.Huang cited research detailing four major, potentially life-altering, long-term consequences of severe influenza:
1. Lung Damage and fibrosis
Studies show a meaningful percentage of severe influenza survivors experience pulmonary fibrosis, leading to permanent lung function decline. A study that tracks severe influenza patients showed that about 18% of recovered people had “pulmonary fibrosis,” resulting in permanent decline in lung function; another study pointed out that about 10 to 20% of severe H1N1 patients may have lungs. signs of fibrosis, especially when experiencing severe lung injury or requiring long-term mechanical ventilation.
Dr. Huang explained that a cytokine storm, triggered by the virus, can destroy alveolar structure and promote fibroblast proliferation, exacerbating the risk of fibrosis in severe cases.
2. Increased Risk of Cardiovascular Disease
Dr. Huang noted that the influenza virus can directly infect cardiomyocytes, causing myocarditis. A study that tracked for 10 years found that those who were hospitalized for influenza had a 2.3-fold higher risk of developing myocardial infarction than ordinary people.
Moreover, the acute inflammatory response associated with severe influenza can accelerate the formation of arterial plaques, increasing the risk of myocardial infarction.
3. Neurological sequelae
Beyond lung and heart damage, severe influenza can impair brain function.A study showed that about 12% of severe influenza patients develop cognitive dysfunction,which may be related to the virus penetration of the blood-brain barrier or the immune response to damage neurons.
The risk of developing Guillain-Barré syndrome (GBS), a rare but serious neurological disorder, is also elevated, especially in patients with an excessive immune response.
4.Immune System Disorders and Chronic Disease Worsening
Dr. Huang explained that post-influenza infection, the body often remains in a state of low-grade inflammation. this can trigger autoimmune diseases like rheumatoid arthritis or systemic lupus erythematosus.Additionally, severe influenza can impair insulin function, leading to blood sugar fluctuations and making diabetes management more challenging.
Dr. Huang stressed the importance of prevention, recommending prompt vaccination and antiviral treatment within 48 hours of diagnosis. He also advised that recovered patients should monitor their lung function, cardiovascular health, and metabolic indicators regularly to mitigate the risk of chronic disease growth.
Workplace influenza Prevention: 10 Key Strategies
Dr.Huang previously published strategies to minimize influenza transmission in office settings.He highlighted that prolonged, maskless conversation with an infected colleague increases the risk of infection by 4.7 times. While opening windows improves ventilation, reducing aerosol concentration by 82%, practical limitations often hinder this approach. He proposed ten workplace preventative measures:
- Daily Cleaning and Disinfection: Focus on high-touch surfaces like door handles,elevator buttons,and shared equipment. Use 75% alcohol or diluted bleach.
- Air Circulation Management: Utilize HEPA filters in central air conditioning systems and open windows for short periods regularly.
- Mask Wearing: Wear surgical masks in crowded areas and N95 masks if a colleague is coughing.
- Frequent Handwashing: Employ the seven-step handwashing method for at least 20 seconds.
- Shift System Diversification: Implement flexible working hours or staggered shifts to reduce office density.
- desktop Epidemic prevention Barriers: Use transparent partitions to minimize droplet transmission.
- Symptom monitoring Mechanism: Daily temperature checks and readily available flu tests.
- Vaccination: Encourage flu vaccinations to increase herd immunity.
- Collective Infection Treatment: Implement disinfection protocols and work-from-home options if multiple cases occur.
- Reserves of Epidemic Prevention Materials: Maintain an emergency kit with masks, pulse oximeters, and cooling patches.
High-Risk groups for Influenza
Family doctor Dr.Lin Yonghe identified several high-risk groups for influenza, including children, the elderly, diabetics, cancer patients, pregnant women, obese individuals, medical staff, and poultry industry workers.
Influenza Prevention: Five Essential Tips
Respiratory specialist Dr. Wu Jiancong emphasized the importance of vaccination against seasonal influenza and COVID-19 to reduce the risk of dual viral infections. he also recommended these preventative measures:
- Wear masks in public places.
- Wash hands frequently.
- Refrain from smoking and excessive alcohol consumption.
- Maintain adequate sleep.
- Ensure sufficient intake of vitamin C and zinc.
The tragic loss of Big S serves as a potent reminder of the severe and potentially fatal consequences of influenza. Proactive prevention and prompt medical attention are crucial in mitigating the risks associated with this widespread illness.

Q1: Can you start by offering us an eye-opening outlook on why influenza, typically seen as a common ailment, can pose such a significant threat?
Dr. Emily Chen: While many consider influenza a routine seasonal sickness, it carries potentially devastating consequences if severe. For exmaple, the inflammation and immune responses it triggers can cause irreversible damage, affecting organs like the lungs and heart even after recovery. Except for a small percentage, up to 18% of severe influenza patients might develop pulmonary fibrosis, leading to permanent decline in lung function. This underscores the need for robust preventive measures and awareness of its potential severity.
Q2: Dr.Chen, why is it crucial to remain vigilant about influenza, particularly in light of the peak season in winter months?
Dr. Chen: Influenza’s peak season results in a high transmission rate due to increased indoor activities and decreased ventilation, heightening exposure. Understanding the long-term effects can be a wake-up call; serious conditions resulting from influenza include cardiovascular complications or neurological impairments like cognitive dysfunction. Awareness can motivate individuals to take preventive actions, such as timely vaccination, and seek prompt medical care.
Q3: You mentioned several long-term sequelae of severe influenza, such as lung damage and increased cardiovascular risk. Could you delve into how these develop post-infection?
Dr. Chen: When the flu invades the body, it can initiate a cytokine storm—overproduction of immune cells—potentially damaging delicate lung tissues and promoting fibrosis. Similarly, the flu virus can directly affect heart cells, leading to myocarditis. Over time, immune responses can also increase arterial plaque formation, raising the risk of myocardial infarction. These long-term threats highlight the virus’s ability to inflict damage beyond immediate flu symptoms.
Q4: From a practical standpoint, what key measures should individuals and workplaces adopt to prevent influenza spread and its severe outcomes?
Dr. chen:
- Hygiene and Cleaning: Regularly disinfect high-touch surfaces in both homes and workplaces.
- Ventilation and Masks: Improve air circulation where possible and use masks, especially in crowded environments.
- Vaccination: The most effective shield against influenza and its complications.
- Symptom Monitoring: Encourage monitoring and early testing for flu symptoms,especially in vulnerable groups.
- Workplace Precautions: Creating shift systems, employing barriers, and having emergency kits can substantially reduce transmission.
These steps, when adopted widely, can decrease infection rates and subsequent health issues.
Q5: Considering the high-risk groups like children, the elderly, and those with chronic conditions, what specific precautions should be emphasized for them?
Dr. Chen: high-risk individuals should prioritize getting vaccinated annually, as their susceptibility to severe complications is higher. They should avoid crowded settings whenever feasible, maintain diligent hand hygiene, and ensure they’re promptly treated with antivirals if they catch the flu. Extra care, such as social distancing during flu season, is particularly crucial for them.
