These days, if you catch the flu, you can't think of it as just a "few days of feeling unwell" like before.

Looking at the situation in the U.S. this year, it's close to a disaster. According to CDC statistics, this year, flu infections have exceeded 33 million cases.

430,000 people have been hospitalized, and there have been 19,000 deaths. This is the most serious level in the past 15 years.

It's no wonder people are saying, "The flu is scary these days."

Particularly concerning is the elderly population. Just looking at California, the situation is clearly evident.

From October of last year to mid-February of this year, there have been 900 flu-related deaths, with 77% of them, or 700, being individuals aged 65 and older.

This indicates that as people age, the flu is no longer just a simple illness but a life-threatening disease.

Sadly, there have also been 86 deaths among children. This means that both the very young and the elderly are the most vulnerable groups.

There are several reasons why the flu has become so frightening.

The first is the virus itself. This year's outbreak is caused by influenza A, specifically H1N1 and H3N2.

These are originally strong strains of the virus, and after mutations, they have become more transmissible and exhibit more severe symptoms, which are different from before. It's not just a runny nose and cough; people describe it as feeling like they've been hit by a dump truck, with severe body aches, high fever, cough, and difficulty breathing.

The second reason is the issue of immunity. Since COVID, people's immune patterns have changed significantly. After years of wearing masks and social distancing, natural immunity to common viruses has decreased. As a result, when the flu comes in, the body can't cope. This is especially true for the elderly, who already have lower baseline immunity.

The third reason is that the current situation isn't just about the flu. These days, the news mentions the term "quardemic."

COVID, the flu, RSV, and avian flu are all circulating at the same time. This puts a greater burden on the healthcare system, and for individuals, it becomes difficult to distinguish which virus they have. Ultimately, this increases the likelihood of delayed treatment.

In conclusion, the reasons the flu has become so scary these days are not just one. It's a combination of the strength of the virus, decreased immunity, simultaneous outbreaks, and living conditions. Therefore, you can't just think, "I'll be fine in a few days" like before.

Particularly, households with individuals aged 65 and older or young children need to be more vigilant.

The realistic response methods are simple: vaccination, hand washing, and responding immediately when symptoms appear.

In short, the flu these days is no longer just a common cold; it has become a life-threatening condition. The significant increase in deaths among the elderly population is the biggest concern.

When immunity is low, the flu can quickly lead to complications like pneumonia, and if treatment is delayed, it can result in fatal outcomes. Recent statistics show that the majority of flu deaths are concentrated among the elderly.

Even if symptoms start mildly, you must not let your guard down. The flu is not an illness to endure; it is a disease that requires early intervention.
