CaliToday (03/12/2025): As the final months of the year arrive, bringing cooler temperatures especially to Northern Vietnam and the bustling anticipation of the Lunar New Year (Tet), health experts are issuing a crucial reminder. This vibrant festive season is also the prime time for a less welcome visitor: a surge in viral respiratory infections, most notably seasonal influenza.
The transition from winter to spring in Vietnam creates a "perfect storm" for pathogens to thrive. The combination of cold, humid weather, significant temperature fluctuations, and the increased frequency of indoor gatherings and travel creates an ideal environment for viruses to spread. Hospitals across the country, particularly pediatric and geriatric wards, typically begin to see a notable rise in admissions during this period.
Here is a closer look at the current health landscape and practical steps to protect yourself and your family.
The Main Culprits: More Than Just a Common Cold
While many may dismiss a sniffle as a simple cold, authorities are urging heightened vigilance against more severe respiratory illnesses that peak during this season.
Seasonal Influenza (The Flu): This is a primary concern. Strains like Influenza A (H1N1, H3N2) and Influenza B are highly contagious and can cause severe illness, leading to hospitalization or even fatalities in vulnerable groups. Unlike a gradual cold, the flu often hits suddenly with high fever, severe body aches, extreme fatigue, and a dry cough.
Other Respiratory Pathogens: Beyond the flu, other viruses like Respiratory Syncytial Virus (RSV)—which can be particularly dangerous for infants and the elderly adenoviruses, and rhinoviruses are actively circulating. The co-circulation of these viruses can complicate diagnosis and treatment.
Who is Most at Risk?
While anyone can get sick, certain groups are far more susceptible to developing severe complications like pneumonia, bronchitis, or the worsening of existing chronic conditions. Special care and proactive protection should be prioritized for:
Young children under the age of 5, especially infants.
The elderly (adults over 65).
Pregnant women.
People with chronic underlying health conditions such as heart disease, diabetes, asthma, or chronic obstructive pulmonary disease (COPD).
Individuals with weakened immune systems.
Your Defense Toolkit: Proactive Measures for a Healthy Season
Vietnam's Ministry of Health and preventive medicine experts strongly recommend adopting a proactive approach to break the chain of transmission. Here are the essential strategies to stay healthy:
1. Get Vaccinated – The First Line of Defense The single most effective way to prevent the flu and its severe complications is annual vaccination. Health officials strongly advise getting the flu shot before the season peaks, ideally around October or November, but getting it now is still beneficial. It is particularly crucial for the high-risk groups mentioned above and their caregivers.
2. Master Everyday Hygiene
Handwashing is Heroic: Wash your hands frequently with soap and water for at least 20 seconds, especially after being in public places, coughing, or sneezing. Alcohol-based hand sanitizers are a good alternative when soap isn't available.
Cough Etiquette: Cover your mouth and nose with a tissue when you cough or sneeze, then dispose of it immediately. If a tissue isn't handy, use your upper sleeve or elbow, not your hands.
Avoid Touching Your Face: Viruses often enter the body through the eyes, nose, and mouth.
3. Be Smart in Crowds The pre-Tet period is filled with shopping and year-end parties. In crowded, enclosed spaces like markets, malls, or public transport, consider wearing a face mask. This simple act protects both you and those around you.
4. Listen to Your Body If you develop flu-like symptoms (fever, cough, sore throat, body aches), the most responsible action is to stay home from work, school, and social gatherings to prevent spreading the virus. Rest, stay hydrated, and seek medical attention if symptoms worsen or if you are in a high-risk group. Do not self-medicate with antibiotics, which are ineffective against viruses.
Conclusion
The winter-spring season in Vietnam is a beautiful time of year, full of cultural richness and family connection. By staying informed and taking simple, proactive health measures—starting with a flu shot and good hygiene you can ensure that you and your loved ones enjoy the festivities safely and enter the new year in good health. Don't let preventable illnesses dampen the holiday spirit.
