- The prevention and control strategybased<br/>on the three links of the epidemic process of infectious diseases<br/>include (). A: Control sources of infection B: Interrupt the route of transmission C: Kill wild animals D: Protect the susceptible population E: Environmental disinfection<br/>判断题
- There was only one peak in the epidemic curve of a disease, and all<br/>cases are concentrated in the common incubation period of the<br/>disease, then the disease transmission mode maybe ( ). A: both<br/>homologous and continuous B: common source epidemic C: mixed type D: human to human E: unable to judge
- The basic features of infectious disease are A: There are infectivity, pathogen, epidemic, immunity. B: There are infectivity, patients, immunity, epidemic. C: There are source of infection, route of transmission, susceptibility, immunity. D: There are infectivity, epidemic, endemic, relapse. E: There are pathogen, reinfection, epidemic, immunity.
- In order to reduce the influence of transmission elements on<br/>transmission accuracy, () transmission should be adopted. A: Deceleration B: Isokinetic C: variable speed D: Speed up
- Which is not the transmission’s job<br/>__? A: To vary the gear ratio B: To provide the directional control C: To interrupt the engine power to the transmission D: To transmit the power to the<br/>half shaft
