How to detect rabies
Rabies is a fatal disease caused by the rabies virus and is spread primarily through bites or scratches from infected animals. Since the mortality rate of rabies is close to 100% once it develops, early diagnosis and prevention are crucial. This article will introduce in detail the examination methods, diagnostic procedures and related hot topics of rabies.
1. Testing methods for rabies
The diagnosis of rabies mainly relies on clinical symptoms, laboratory tests and epidemiological history. The following are common inspection methods:
| Check method | Description | Applicable stage |
|---|---|---|
| Observation of clinical symptoms | The doctor makes a preliminary judgment by observing whether the patient has symptoms such as hydrophobia, windphobia, excitement, and paralysis. | onset period |
| Viral Antigen Test | Detection of viral antigens in brain tissue or saliva by fluorescent antibody test (FAT) | During illness or after death |
| Nucleic acid detection | RT-PCR technology is used to detect viral RNA with high sensitivity | incubation period or onset period |
| Serological testing | Detection of viral antibodies in blood, suitable for evaluation of effectiveness after vaccination | incubation period or onset period |
| Brain biopsy | By collecting brain tissue samples for pathological examination, the diagnosis rate is high | after death |
2. Diagnosis process of rabies
The diagnosis of rabies usually follows the following process:
1.Epidemiological history investigation: Doctors will ask patients if they have a history of being bitten or scratched by animals, especially high-risk animals such as dogs and cats.
2.clinical symptom assessment: Observe whether the patient develops typical symptoms, such as hydrophobia, windphobia, muscle spasms, etc.
3.Laboratory testing: Choose the appropriate detection method according to the condition, such as viral antigen detection or nucleic acid detection.
4.Comprehensive judgment: Make a final diagnosis based on medical history, symptoms and test results.
3. Recent hot topics and hot content
In the past 10 days, discussions about rabies have mainly focused on the following aspects:
| hot topics | Hot content | Related data |
|---|---|---|
| Rabies vaccine supply | Shortages of rabies vaccine reported in many places, sparking public concern | Only 30% of inventory remains in a certain province |
| Pet dog management | The number of stray dogs in cities increases, and the risk of rabies rises | The number of stray dogs in a city increased by 20% year-on-year |
| New detection technology | Scientific research team develops new method to rapidly detect rabies | Testing time shortened to 1 hour |
| international epidemic | Rabies cases surge in Southeast Asian countries, travel warnings issued | The number of cases in a certain country increased by 50% |
4. How to prevent rabies
1.Avoid contact with high-risk animals: Stay away from stray dogs, cats and other animals that may carry viruses.
2.Get vaccinated promptly: After being bitten, the wound should be cleaned immediately and vaccinated against rabies.
3.Strengthen pet management: Vaccinate domestic pets to protect them from contact with wild animals.
4.Raise public awareness: Through publicity and education, let more people understand the dangers and preventive measures of rabies.
5. Summary
The diagnosis of rabies requires a combination of clinical symptoms, laboratory testing, and epidemiological history. Early detection and prevention are key to rabies control. Recent discussions about rabies have focused on vaccine supply, pet management, and new testing technologies. The public should be more vigilant and take effective measures to prevent the occurrence of rabies.
