Analysis of the Current Status of Injuries Caused by Dog-Related Animals in the Taihu Lake Region: A Quality Assessment of Post-Exposure Prophylaxis in 40,222 Cases (2023–2025) and Implications for Rabies-Free Areas
This study of 40,222 animal injury cases in the Taihu Lake region (2023–2025) reveals that despite the area's rabies-free status, "prevention fatigue" has led to suboptimal post-exposure prophylaxis quality—particularly among young adults, scratch victims, and delayed presenters—though recent data suggests targeted interventions are beginning to reverse these trends.

The Big Picture: The "Silent Slump" in a Safe Zone
Imagine the Taihu Lake region (a wealthy, urban area in China including cities like Wuxi) as a fortress that has been free of a dangerous monster (rabies) for over a decade. Because the monster hasn't attacked in years, the guards (doctors) and the townspeople (the public) have started to relax. They think, "We're safe, so we don't need to be as strict."
This study, which looked at 40,222 people who got scratched or bitten by dogs and cats between 2023 and 2025, found that this relaxation is dangerous. Even though no one in this region has died from rabies recently, the quality of the "safety checks" (medical treatment) given to injured people is slipping. The researchers call this "Prevention Fatigue." It's like a fire drill that hasn't been practiced in years; when the real fire starts, everyone forgets the exit routes.
The Problem: Missing the "Safety Net"
When someone gets a severe animal bite (called a "Grade III" injury), the gold-standard treatment is a two-part safety net:
- Cleaning the wound thoroughly.
- Injecting a "shield" (passive immunization, like rabies immunoglobulin) immediately to stop the virus before it spreads.
The Findings:
- The Shield is often missing: Even for severe injuries, only about 55% of patients got the "shield" injection. That means nearly half of the people with the most dangerous wounds left the hospital without this critical protection.
- The "Perfect" Treatment is rare: Only 45% of severe cases got both the cleaning and the shield.
- The "Wait and See" problem: About 35% of people waited more than 6 hours after getting hurt before coming to the hospital. Waiting is risky because the virus travels fast.
Who is Most at Risk? (The "Perfect Storm" Groups)
The study identified three specific groups of people who are most likely to miss out on this safety net. Think of these as three overlapping holes in the armor:
- Young Adults (Ages 15–44): These are the busiest people in society. They are twice as likely as children to skip the "shield" injection. They are also the most likely to wait before seeking help, perhaps because they are too busy or think, "It's just a scratch, I'll deal with it later."
- Scratch Victims: There is a dangerous misconception that scratches are less dangerous than bites. The study found that people with scratches were much more likely to be denied the "shield" or to wait longer to get help. The doctors and patients often underestimate the risk of a cat scratch, but the virus doesn't care if it came from a bite or a scratch.
- The Delayers: Anyone who waits more than 6 hours is at higher risk. Interestingly, winter makes this worse. In cold weather, people wear thick coats that hide wounds, and the cold makes them less eager to go outside, leading to longer delays.
The Good News: The "Wake-Up Call" is Working
While the situation was worrying, the study found a glimmer of hope. Between 2023 and 2025, things started to get better.
- More people are getting the "shield" injection (up from 52.8% to 60.1%).
- Fewer people are waiting too long to come to the hospital.
This suggests that the hospital (Wuxi No.8 People's Hospital) has started a quality improvement program—like a coach giving the team extra drills. This systematic effort is beginning to reverse the "Prevention Fatigue."
The Takeaway: Don't Let the Silence Lull You
The main lesson from this paper is simple: Just because you haven't seen the monster in a long time doesn't mean it's gone.
The region is technically "rabies-free," but the study warns that this status is fragile. If the quality of medical care drops because everyone feels too safe, the region could become vulnerable again.
The authors recommend:
- Stop ignoring scratches: Treat a severe scratch with the same seriousness as a severe bite.
- Watch out for young adults: They need specific reminders to get treated immediately.
- Use "Sentinel Indicators": Instead of just waiting to see if someone dies of rabies (which is too late), hospitals should track how many people are getting the "shield" injection. If that number drops, it's a warning sign that the system is failing, even if no one is sick yet.
In short, the paper argues that to stay safe, we must keep our guard up even when the danger seems invisible.
