Identification and diagnosis of plague

Basic overview of plague

Plague definition: Plague is an acute infectious disease caused by Yersinia pestis.

Plague is transmitted through vectors such as infected rats and fleas.

clinical manifestations of plague

There are three forms of plague: bubonic plague, pneumonic plague, and septicemic plague.

Symptoms of bubonic plague: local lymph node swelling, fever, headache, etc.

Symptoms of pneumonic plague: high fever, chills, cough, difficulty breathing, etc.

Symptoms of septicemic plague: high fever, obvious systemic symptoms, cardiovascular failure, etc.

Differential Diagnosis of Plague

Clinical manifestations: Judgment is based on the characteristics of different forms of plague and the clinical manifestations of the patient.

Investigation of the source of infection: Track and investigate the source of infection of patients and their contacts, and find the source of infection through epidemiological investigation.

Laboratory testing: Pathological testing to determine the presence of the plague pathogen.

Cellulase-mediated gel amylase test: detects the presence of Yersinia pestis.

Culture and Identification: Diagnosis is made by culturing and characterizing Yersinia pestis.

Genetic testing: Use molecular biology methods such as PCR to detect the DNA of Yersinia pestis.

Imaging examination: Use X-ray, CT and other imaging examination methods to observe changes in relevant tissues.

Plague treatment, prevention and control

Antibiotic treatment: Treatment with antibiotics such as penicillins.

Supportive treatment: symptomatic treatment, maintaining water and electrolyte balance, maintaining smooth respiratory tract, etc.

Isolation measures: Isolate the patient to avoid spreading it to others.

Prevent flea bites: Take anti-flea measures, such as using flea spray.

Vaccination: Plague vaccination provides active immune protection.

Environmental disinfection: Thoroughly disinfect the patient's location to prevent reinfection by rodents.

Plague prevention

Strengthen health education: Improve public awareness of plague and prevention awareness.

Environmental health management: Reduce environmental pollution where rodents and fleas breed.

Rodent Control: Control sources of infection through rodent eradication and rodent monitoring.

Flea control: Take anti-flea measures such as exterminating fleas and eliminating flea breeding sites.

Get vaccinated against plague: Vaccination provides passive immune protection.

Construction of resident protective facilities: Construct resident protective facilities and provide epidemic prevention and disinfection materials, etc.
