Practical Guidelines for Preventing Influenza and COVID-19 During the Chuseok Holiday

During the Chuseok holiday, long-distance travel, indoor meals, and stays involving multiple generations become more common. Respiratory infections such as influenza and COVID-19 can spread in crowded indoor settings, so it is advisable to review vaccination plans and establish clear steps to follow if symptoms develop. If family members at a higher risk of severe illness, such as older adults or infants and young children, will be present, their health status should be assessed with added care before the gathering.

Influenza and COVID-19 may both begin with similar symptoms, including fever, cough, sore throat, runny nose, muscle aches, and fatigue. Because it can be difficult to identify the cause based on symptoms alone, testing and consultation with a healthcare professional are advisable when symptoms persist or when contact with high-risk individuals is anticipated.

Review Vaccination Status and Health Conditions Before the Holiday

Influenza vaccination is recommended before the seasonal surge begins. Because the immune response requires time to develop after vaccination, those planning to visit their hometown or attend family events should confirm vaccine availability and scheduling with a healthcare provider in advance. COVID-19 vaccination recommendations may vary depending on age, underlying health conditions, and prior vaccination history; therefore, the latest guidance from public health authorities, including the Korea Disease Control and Prevention Agency, should be reviewed.

Vaccination is a public health measure intended to reduce the risk of severe illness and hospitalization. If a gathering includes older adults, pregnant individuals, infants and young children, or family members with cardiopulmonary disease, diabetes, or weakened immune function, it is important to review their vaccination history and recent health status.

On the day before departure, it is helpful to check for symptoms that differ from one’s usual condition, including fever, body aches, sore throat, a newly developed cough, or marked fatigue. Even mild symptoms warrant caution if long hours of shared vehicle travel or crowded meals are planned. Prepare a mask and inform family members in advance so that visit times or overnight arrangements can be adjusted if necessary.

Influenza and COVID-19 Are Difficult to Distinguish by Symptoms Alone

Influenza may cause sudden fever, chills, muscle aches, headache, and fatigue, sometimes accompanied by cough and sore throat. COVID-19 can likewise present with a range of respiratory symptoms, including fever, cough, fatigue, and sore throat. As symptom severity and order of onset vary from person to person, it is difficult to determine the type of infection based on any single symptom.

If fever or coughing begins during the holiday, reduce close contact with other family members and, where possible, separate eating and sleeping spaces. Avoid plans that involve prolonged time together in poorly ventilated indoor environments. If shared spaces must be used, wearing a mask and maintaining hand hygiene are recommended. Plans to share a room with grandparents or young children should also be reconsidered if symptoms develop.

At-home tests may help identify an infection, but negative results can occur early in the course of symptoms. Even with a negative result, repeat testing or contacting a healthcare provider may be considered if fever or respiratory symptoms continue and contact with high-risk individuals is expected. Test results should be assessed alongside current symptoms, the people involved in potential contact, and the presence of underlying health conditions.

Manage Ventilation and Meal Arrangements at Family Gatherings

Kitchens and dining tables are areas where many people may remain together for extended periods. Opening windows regularly to refresh indoor air can help, and during car travel, using outside-air intake or ventilation functions when safe to do so may reduce time spent in enclosed conditions.

Hygiene can be supported by using individual plates and assigning separate ladles and tongs for shared dishes. Carrying an alcohol-based hand sanitizer is also useful when handwashing is difficult during travel. Hand hygiene deserves particular attention before meals, after using the restroom, after coughing or sneezing, and after caring for young children.

If a family member has a cough or is sneezing, it is advisable to shorten meal and conversation times. Masks may help reduce the spread of respiratory secretions in crowded indoor spaces or during long-distance public transportation. Ventilation, hand hygiene, and maintaining distance when symptoms occur should be practiced together.

It is also helpful to organize contact information for attendees before the gathering. If someone is diagnosed with influenza or COVID-19 after the event, attendees should be informed briefly of the date, symptom onset, and whether testing was performed. This allows high-risk individuals to monitor their symptoms and seek medical care when needed.

Make Timely Decisions About Medical Care When Symptoms Develop

When respiratory symptoms appear, the first priority is to avoid unnecessary travel and reduce participation in gatherings. Adequate hydration and rest are important. If persistent high fever, breathing difficulty, chest pain, altered consciousness, or severe dehydration occurs, seek medical attention without delay. Infants and young children, older adults, pregnant individuals, immunocompromised people, and those with chronic conditions should consider seeking medical advice earlier, even when symptoms appear mild.

For high-risk individuals with suspected influenza, early clinical assessment after symptom onset may be beneficial. The decision to use antiviral medication and the timing of treatment are determined by a healthcare professional based on age, underlying conditions, symptom progression, and test results. Leftover medication should never be shared among family members, and treatment decisions should not be made based solely on online information.

Care plans for COVID-19 may also differ according to individual risk. If you take regular medications or have kidney or liver function concerns, cardiovascular disease, or immune-related conditions, prepare a list of medications to present during your consultation. This article does not replace individual diagnosis or treatment, and clinical judgment tailored to symptoms and risk factors is essential.

Holiday Health Management Begins with Small Schedule Adjustments

Reviewing vaccination status and physical condition before departure, maintaining ventilation during travel, and choosing to step back from gatherings when symptoms arise can help protect the entire family. When vulnerable family members are present, prioritize travel plans and lodging arrangements that allow everyone to return home safely rather than focusing solely on attendance.

Patterns of influenza and COVID-19 circulation, as well as vaccination recommendations, may vary by season. As the holiday approaches, review guidance from the Korea Disease Control and Prevention Agency and local public health authorities, and prepare essential supplies and healthcare provider contact information in advance.
