02 CDC interview professional knowledge (real questions over the years)

1. What is a public health emergency and what harm does it do to society?

Definition: refers to the sudden occurrence of major infectious diseases, mass unexplained diseases, major food and occupational poisoning and other events that seriously affect public health, which have caused or may cause serious damage to public health.

Harm: public health (physical and mental); Public interests; Economic order and social order; Unexpected events can cause different degrees of harm to public health and life safety, social and economic development, ecological environment, etc. This kind of harm can be immediate and serious damage to society, and it can also be an event that has a serious impact on society from the perspective of development trend. Its harm can be manifested as direct harm and indirect harm. Direct harm is generally the immediate damage directly caused by the event, while indirect harm is generally the secondary damage or harm of the event, for example, the event causes public panic and anxiety, which has an impact on society, politics and economy.

2. What are the types of public health emergencies?

There are many ways to classify public health emergencies, which can be divided into:

(1) Diseases caused by biological pathogens: mainly refer to infectious diseases (including infectious diseases of several animals), parasitic diseases, endemic diseases, regional epidemics, outbreaks or deaths; Prevention of vaccination or prevention of group abnormal reactions after taking medicine; Group hospital infection, etc. Infectious diseases have ravaged human history for thousands of years, which have caused great disasters in the world. Although scientific and technological progress has invented drugs and biological agents such as antibiotics and vaccines, which have brought infectious diseases under control, the incidence of infectious diseases still ranks first in the world every year. The reasons are as follows: 1. Some controlled infectious diseases such as tuberculosis and malaria have resurfaced. 2. A series of new infectious diseases, such as AIDS and Ebola, have been found to pose a serious threat to human beings. 3. Especially during and after the First and Second World Wars, some imperialist countries artificially developed and used deadly infectious diseases in military wars, that is, biological warfare (or bacteriological warfare), which brought harm and panic to mankind.

(2) Food poisoning: Food poisoning refers to a non-infectious acute or subacute disease that occurs after people ingest biological and chemical toxic and harmful substances or take toxic and harmful substances as food, and belongs to the category of food-borne diseases.

(3) Group poisoning, poisoning death or harm caused by pollution of toxic and harmful factors: This kind of public health incident is caused by pollution, such as water pollution, air pollution, radiation pollution, etc., and it has a very wide range. According to statistics, 28 people die of environmental pollution every minute in the world, and 14.72 million people die every year. And because of the pollution caused by toxic and harmful substances. It often does great harm to the next generation.

(4) Natural disasters: Sudden attacks by natural disasters, such as earthquakes, volcanic eruptions, mudslides, typhoons, floods, etc., will cause a large number of loss of life and property, production stoppage, material shortage, and the victims will be homeless. Seeing that the harmonious living conditions created by generations of people are destroyed, decades of hard work will be wasted, which will aggravate various social problems and bring serious social and psychological factors.

(V) Death caused by accidents: We are shocked by major production safety accidents such as coal mine gas explosion, plane crash and air raid, and some life accidents are also seriously threatening people’s safety. This kind of event has no preparation and warning in advance. It often causes huge economic losses and casualties.

(6) Group illness or death caused by unknown reasons: This kind of incident is usually much more serious than the previous categories because it is caused by unknown reasons. First, the causes of such incidents are unknown, and the public lacks the corresponding knowledge of protection and treatment. At the same time, there is no specific monitoring and early warning system for this incident, which often causes serious consequences. In addition, due to unknown reasons, it is also very difficult to control.

3. How to carry out epidemiological investigation?

When public health emergencies occur, only by applying epidemiological methods in a standardized way can we find out the causes and take effective measures in time to prevent the spread and harm of the disease. Public health emergencies often occur in the form of disease outbreaks or cluster epidemics. In epidemiological investigation, outbreak investigation is used for research, and the specific steps are as follows:

(1) Preparation and organization. Generally speaking, we should start from several aspects: defining the scope, dividing the region and determining the key points, and forming an investigation team; Clear personnel arrangement; Prepare relevant books and scheme references and provide technical support; Do a good job in material preparation and logistics support; Get the support of the laboratory and arrange the collection and testing of specimens; Go to the scene immediately after the preparations are completed.

(2) Verify the diagnosis. According to the clinical manifestations, laboratory examination and epidemiological data of the case, comprehensive analysis was made to make a judgment.

(3) Determine the existence of the outbreak. Determine the authenticity of the outbreak information. Once it is confirmed to be true, immediately analyze the overall trend of the outbreak, the affected scope, and the nature and severity of the disease, and make emergency preparations and organization for outbreak control.

(4) Case definition. Determine a unified standard for finding cases, so that the found cases are comparable and meet the requirements of public health emergencies investigation.

(5) Case discovery and verification. Use the existing disease surveillance system to search for cases, or establish an active surveillance system to improve the ability to find cases. After the case is found, timely treatment and isolation, case investigation for the patient, and protection and close observation of those who have close contact with the patient.

(6) Describe the three distribution of diseases. To find the high-risk groups and the key points of prevention and control, and provide the basis for disease prevention and control. It can also describe the relationship between some factors and diseases, so as to gradually establish the hypothesis of etiology.

(7) Establishing hypothesis and verifying hypothesis. Consult experts in related fields in time when establishing hypotheses, and pay attention to the scene to find clues. In an outbreak investigation, there are often several hypotheses, which should include: the source of infection, transmission mode and risk factors, high-risk groups, dose-response relationship and so on. Then use case-control study or cohort study to test the hypothesis.

(8) Improve the on-site investigation. For new or unexplained diseases, it is necessary to further understand their natural history, etiology/source and mode of transmission. For known diseases, we should master more characteristics, such as analyzing risk factors, evaluating diagnostic methods and measuring the effects of control measures.

(9) Implement control measures. The implementation of control measures should be carried out simultaneously with the on-site investigation. For example, once some patients are found, they must be treated in isolation.

(10) summary report. Including initial report, progress report and closing report. There can be multiple progress reports. With the development of the epidemic, it is necessary to report the development trend of the epidemic, the latest incidence and the latest investigation results in a timely manner. During the investigation, we should pay attention to the synchronization of investigation and control, make full use of legal weapons, pay attention to ethical issues, cooperate extensively and strengthen media communication.

In a word, the significance of epidemiological research is to find out the causes, control the further development of the disease, stop the outbreak or epidemic, and improve the ability of disease surveillance. Only by carrying out epidemiological research can we find out the cause or find the clues and risk factors of the cause, so as to explore the whole picture of the disease. Controlling and preventing the further spread of diseases is the key to deal with public health emergencies represented by infectious diseases, and it is also the fundamental purpose of epidemiological investigation and research.

4. The definition of epidemic distribution and under what circumstances?

Sporadic refers to the sporadic occurrence in a certain area where the incidence of a disease is at the general level over the years, and there is no obvious connection between cases in terms of the time and place of onset. To determine whether a disease is sporadic in a certain area, we should refer to the incidence of the disease in the first three years in this area.

Reason:

(1) The disease is prevalent all the year round, and people have certain immunity or maintain their immune level due to vaccination, such as measles.

(2) Infectious diseases with recessive infection, such as poliomyelitis and viral hepatitis.

(3) Infectious diseases whose transmission mechanism is difficult to realize, such as epidemic relapsing fever.

(4) Infectious diseases with long incubation period, such as leprosy.

5. What are the parts of infectious disease case investigation?

Part I (general items): name, gender, age, education level, nationality, occupation, work unit and address;

The second part (special needs items or research variables): (1) Clinical data: onset, time and place of medical treatment and admission, main symptoms, signs, test results, diagnosis and treatment. (2) Epidemiological history: past history, contact history, vaccination history, activities before and after onset, possible infection time, place, mode, possible source of infection, transmission route and contacts. (3) Control measures: isolation time and place, disinfection situation. (4) Conclusion: Source of infection, route of transmission and possible range of transmission;

The third part (exposure factors): diet, drinking water, environmental sanitation conditions, production methods, meteorological conditions, geographical conditions, historical epidemic situation and other possible factors;

Part IV (Notebook Item): Investigator and date of investigation.

6. Definition, epidemiological characteristics and prevention measures of influenza.

Influenza is an acute respiratory infection caused by influenza virus, and it is also a highly contagious and fast-spreading disease. It is mainly spread by droplets in the air, contact between people or contact with contaminated items. The symptoms of this disease are acute onset, severe headache, chills, fever, general aches and weakness, and the symptoms of the whole body are severe, while the symptoms of the upper respiratory tract (such as sore throat, cough, spitting and runny nose) are not obvious. Sometimes patients have complications such as nausea, vomiting, otitis media, bronchitis and pneumonia.

Features: Sudden occurrence, rapid spread, peak in 2 ~ 3 weeks, high incidence, short epidemic period, about 6 ~ 8 weeks, and often spread along traffic lines.

Prevention and control measures: 1. Try to avoid places with many people and poor air circulation during the winter and spring epidemic, such as supermarkets, markets, hospitals and other places. 2. Pay attention to respiratory protection. If you go to a crowded place with bad air, you can wear a mask to reduce the inhalation of influenza virus in the air. 3. Improve immunity, eat a reasonable diet, eat more fruits and vegetables, avoid overwork, avoid catching cold, contact with flu patients and other incentives, and take appropriate physical exercise to enhance physical fitness, thus reducing the risk of illness. 4. Vaccinate against influenza, especially for the elderly and infirm who can go to the local CDC for influenza vaccination before winter comes, which can prevent the main subtypes prevalent this year. 5. Drug prevention: oral anti-influenza drugs can be taken to prevent the occurrence of influenza after contact with influenza patients. Commonly used drugs include oseltamivir.
