Recently, news about influenza has attracted widespread attention: Data released by the Chinese Center for Disease Control and Prevention (China CDC) shows that the flu positivity rate among influenza-like cases in outpatient and emergency departments nationwide has approached 45%, with the overall situation entering a moderate epidemic level, and some provinces even reaching a high epidemic level. As the weather turns cold, respiratory diseases have entered a period of high incidence, and flu activity is showing a rapid upward trend.
Why Do So Many People Seem to Have Been Infected This Year?
The current flu outbreak is fierce, with many families having members infected—especially children. There are several key reasons behind this:
Change in Circulating Strains: The dominant flu strain in China currently is influenza A (H3N2). The last large-scale outbreak of this strain occurred approximately two years ago, and the general population lacks targeted immunity, leading to an increase in susceptible individuals.
High Population Density: Places such as schools and kindergartens are densely populated. Once a source of infection is introduced, the virus can spread rapidly. Monitoring data shows that the flu virus detection positivity rate in the 5-14 age group is significantly higher than in other age groups.
Climatic and Environmental Factors: Indoor activities increase in winter, and doors/windows are often closed, resulting in reduced ventilation—creating favorable conditions for virus transmission.
Experts predict that the peak of this flu activity is expected to occur from mid-to-late December to early January, meaning the next few weeks are a critical window for strengthening protection.
Flu vs. Common Cold: Stop Confusing the Two
Many people confuse the flu with the common cold, underestimating its hazards. In fact, there are significant differences between the two:
Common Cold: Symptoms are mainly concentrated in the nasopharynx, such as stuffiness, runny nose, and sore throat. Symptoms are usually mild, with fever being rare or only low-grade. It is less contagious and rarely causes severe complications.
Influenza (Flu): An acute respiratory infectious disease caused by specific influenza viruses. It has an abrupt onset and launches a fierce attack on the "entire body system," mainly manifesting as sudden high fever (often 39℃-40℃), chills, severe headache, generalized muscle aches, and extreme fatigue. Highly contagious, it may cause severe complications such as pneumonia and myocarditis in high-risk groups, including infants, the elderly, pregnant women, and patients with chronic underlying diseases.
A Key Link in Home Protection: A Clean Air Environment
In addition to personal protection, creating a safe indoor home environment is equally crucial. In winter, doors and windows are tightly closed, resulting in poor indoor air circulation. Flu viruses can spread not only through droplets and contact but also through air in the form of aerosols in enclosed, poorly ventilated environments.
Experts have repeatedly emphasized the importance of opening windows for ventilation. However, this measure is often difficult to sustain in freezing weather, smoggy conditions, or when there are sick people at home where opening windows is inconvenient. At such times, actively and continuously purifying and disinfecting indoor air becomes a key measure to protect family members—especially vulnerable groups such as the elderly and children.
This is precisely the "last cubic meter of air environment management" problem that Kangbeijing is committed to solving. As a high-tech enterprise focusing on air health management, Kangbeijing deeply understands that clean air is the cornerstone of health.
Kangbeijing: Guarding Every Breath with Technological Strength
During the high flu season, providing an invisible "air protection shield" for families and key venues is particularly important. Kangbeijing's plasma air disinfection and purification machine was born out of this concept.
Its core DBD (Dielectric Barrier Discharge) plasma technology can, in environments where humans and machines coexist, release high-energy plasma clusters in real time and proactively. These clusters surround and decompose pathogenic microorganisms such as flu viruses in the air, destroying their protein structures and rendering them inactive. Certified by third-party authoritative institutions, this technology achieves an average inactivation rate of over 99.99% against various pathogens, including human coronaviruses.
This means that whether it is potential risks brought home by children from school or daily interactions among family members in enclosed living rooms, Kangbeijing's equipment acts as a silent guardian, working 24/7 to actively purify every cubic meter of air and effectively reduce the risk of virus transmission among family members.
In addition to high-efficiency disinfection capabilities, Kangbeijing's products also have multiple functions such as odor removal, formaldehyde decomposition, and allergen purification, aiming to restore a fresh and healthy indoor environment like that of a forest. The products have obtained numerous domestic and international certifications, including ISO9001 and EU CE, and serve many professional medical institutions and public venues such as the National Center for Cardiovascular Diseases, Gansu Provincial People's Hospital, and The First Affiliated Hospital of Zhejiang University School of Medicine. Their quality and effectiveness have undergone rigorous verification.
Protecting family health during flu season requires comprehensive wisdom. While practicing scientific measures such as frequent hand washing, mask wearing, and vaccination, introducing a reliable "air defense line" to your home, office, or classroom is undoubtedly a deeper level of care and responsibility.
Kangbeijing purifies every breath with innovative technology, wholeheartedly guarding the health of you and your family through all seasons.
