Types of infectious diseases, what are the types of infectious diseases

Infectious diseases are divided into Class A, Class B and Class C infectious diseases

1. Class A infectious diseases, including plague and cholera.

2. Category B infectious diseases, including infectious atypical pneumonia and AIDS.

Viral hepatitis, poliomyelitis.

Human infection with highly pathogenic avian influenza, measles, epidemic haemorrhagic fever.

Rabies, Japanese encephalitis, dengue fever, anthrax, bacterial and amoebic dysentery, tuberculosis, typhoid and paratyphoid, epidemic encephalomyelitis, whooping cough, diphtheria, neonatal tetanus, scarlet fever, brucellosis, gonorrhea, syphilis.

Leptospirosis, schistosomiasis, malaria, human infection with swine streptococcal disease, influenza A (H1N1).

3. Category C infectious diseases, including epidemic disease, mumps, rubella, acute hemorrhagic conjunctivitis, leprosy, epidemic and endemic typhus, kala-azar and echinococcosis, filariasis, infectious diarrheal diseases other than cholera, dysentery, typhoid fever and side injuries, and hand, foot and mouth disease.

According to different transmission routes, infectious diseases can be divided into the following types: 1. Respiratory infectious diseases: they are the most likely diseases, such as influenza A (H1N1) and SARS in 2003, which are caused by respiratory infection, and can cause a large number of people to be infected once they occur; 2. Digestive tract infectious diseases

Bacillary dysentery, cholera, etc., are diseases that are transmitted through the digestive tract and are caused by eating unclean food or drinking unhygienic water. 3. Insect-borne infectious diseases: such as malaria, which requires a specific transmission medium; 4. Contact infectious diseases: such as hand, foot and mouth disease, caused by contact with infected viruses; 5. Blood-borne diseases:

Such as hepatitis B or C; 6. Maternal and infant vertical infectious diseases: such as AIDS.

There are a total of 39 kinds of infectious diseases legally notified by the state, and the novel coronavirus pneumonia that prevalent in 2019 is classified as a Class B infectious disease.

In order to prevent, control and eliminate the occurrence and epidemic of infectious diseases and to safeguard human health and public health, the Standing Committee of the National People's Congress enacted the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases. Notifiable infectious diseases are infectious diseases that the state stipulates by law to strengthen management. Originally, there were a total of 39 kinds of infectious diseases legally registered in the country, and the new coronavirus pneumonia epidemic in 2019 was classified as a Class B infectious disease, and there are currently a total of 40 notifiable infectious diseases.

The health administrative department may increase or decrease the types of bacteria (viruses) according to the situation.

Legal basis: Article 3 of the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases The infectious diseases stipulated in this law are divided into Category A, Category B and Category C. Class A infectious diseases refer to:

Plague, cholera. Category B infectious diseases are: infectious atypical pneumonia, AIDS, viral hepatitis, poliomyelitis, human infection with highly pathogenic avian influenza, measles, epidemic haemorrhagic fever, rabies, Japanese encephalitis, dengue fever, anthrax, bacterial and amoebic dysentery, tuberculosis, typhoid and paratyphoid, meningoccal meningitis, pertussis, diphtheria, neonatal tetanus, scarlet fever, brucellosis, gonorrhea, syphilis, leptospirosis, schistosomiasis, malaria.

Category C infectious diseases refer to: epidemic disease, mumps, rubella, acute hemorrhagic conjunctivitis, leprosy, epidemic and endemic typhus, kala-azar disease, echinococcosis, filariasis, infectious diarrheal diseases other than cholera, bacterial and amoebic dysentery, typhoid fever and paratyphoid. According to the outbreak of infectious diseases, the situation of the epidemic and the degree of harm, the administrative department of health may decide to increase, decrease or adjust the types of infectious diseases in categories B and C and make them public.

There are a total of 39 kinds of infectious diseases in China, which can be divided into Category A, Category B and Category C. Infectious disease is a disease that is contagious and has the potential to cause an epidemic after the pathogen infects the human body. Category A includes plague and cholera, worldwide infectious diseases that require mandatory management.

There are a total of 26 kinds of Class B infectious diseases, such as AIDS, viral hepatitis, etc., of which 4 diseases are Class B infectious diseases, but they should be reported and controlled according to Class A infectious diseases, referring to SARS, pulmonary anthrax, human infection with highly pathogenic avian influenza and polio. There are a total of 11 types of Class C infectious diseases, which belong to the lowest level, such as epidemic **, mumps, hand, foot and mouth disease, etc.

There are many kinds of infectious diseases, and the infectious diseases we stipulate are: Class A infectious diseases are also known as compulsory management infectious diseases, including: plague, cholera.

Category B infectious diseases, also known as strictly managed infectious diseases, include: infectious atypical pneumonia, AIDS, viral hepatitis, poliomyelitis, human infection with highly pathogenic avian influenza, measles, epidemic haemorrhagic fever, rabies, Japanese encephalitis, dengue fever, anthrax, bacterial and amoebic dysentery, tuberculosis, typhoid and paratyphoid, meningoccal meningitis, pertussis, diphtheria, neonatal tetanus, scarlet fever, brucellosis, gonorrhea, syphilis, leptospirosis, schistosomiasis, malaria, Influenza A (H1N1) (formerly known as human infection with swine flu).

Prevention and control of such infectious diseases should be carried out in strict accordance with the relevant regulations and prevention and control plans. Among them, four infectious diseases, namely infectious atypical pneumonia, pulmonary anthrax in anthrax, human infection with highly pathogenic avian influenza and influenza A (H1N1), are classified as Category B, but the prevention and control measures of Category A infectious diseases can be directly taken. Category C infectious diseases, also known as surveillance and management infectious diseases, include:

Epidemic **, mumps, rubella, acute hemorrhagic conjunctivitis, leprosy, epidemic and endemic typhus, kala-azar disease, echinococcosis, filariasis, infectious diarrheal diseases other than cholera, bacterial and amoebic dysentery, typhoid and paratyphoid. Such infectious diseases should be managed according to the monitoring and management methods prescribed by the health administrative department.

Class A infectious diseases (2 types) are: plague and cholera. (highly infectious, highly pathogenic, high mortality) Class B infectious diseases (26 types) refer to:

Infectious atypical pneumonia (severe acute respiratory syndrome), AIDS, viral hepatitis, poliomyelitis, human infection with highly pathogenic avian influenza, influenza A (H1N1), measles, epidemic haemorrhagic fever, rabies, Japanese encephalitis, dengue fever, anthrax, bacterial and amoebic dysentery, tuberculosis, typhoid and paratyphoid, meningococcal meningitis, pertussis, diphtheria, neonatal tetanus, scarlet fever, brucellosis, gonorrhea, syphilis, leptospirosis, schistosomiasis, malaria. Category C infectious diseases (11 kinds) refer to: epidemic **, mumps, rubella, acute hemorrhagic conjunctivitis, leprosy, epidemic and endemic typhus, kala-azar, echinococcosis, filariasis, infectious diarrheal diseases other than cholera, bacterial and amoebic dysentery, typhoid fever and paratyphoid, hand, foot and mouth disease.

There were originally 37 notifiable infectious diseases, but in recent years there have been three more notifiable diseases. There are 40 types in total.

1.On May 2, 2008, the Ministry of Health decided to include HFMD as a Category C infectious disease under the Law on the Prevention and Control of Infectious Diseases.

2.April 30, 2009: The Ministry of Health included influenza A (H1N1) (formerly known as human infection with swine flu) as a Class B infectious disease stipulated in the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases, and adopted measures for the prevention and control of Class A infectious diseases.

Human infection with H7N9 avian influenza was included in the list of notifiable Class B infectious diseases; Influenza A (H1N1) was adjusted from category B to category C and included in the existing epidemic for management.

According to the different modes of transmission, speed and degree of harm to human beings, they are divided into three categories: A, B and C, and classified management is implemented.

1) Class A infectious diseases: also known as compulsory management infectious diseases, 2 types: plague and cholera.

2) Class B infectious diseases: also known as strictly managed infectious diseases, 26 kinds: infectious atypical pneumonia, human infection with highly pathogenic avian influenza, viral hepatitis, bacterial and amoebic dysentery, typhoid and paratyphoid, AIDS, gonorrhea, syphilis, polio, measles, pertussis, diphtheria, neonatal tetanus, meningococcal meningitis, scarlet fever, epidemic hemorrhagic fever, rabies, leptospirosis, brucellosis, anthrax, Japanese encephalitis, tuberculosis, schistosomiasis, malaria, dengue fever, Human infection with H7N9 avian influenza.

3) Category C infectious diseases: also known as infectious diseases under surveillance and management, 12 kinds: epidemic and endemic typhus, kala-azar, filariasis, hydatid disease, leprosy, epidemic **, mumps, rubella, acute hemorrhagic conjunctivitis, as well as infectious diarrheal diseases other than cholera, dysentery, typhoid fever and paratyphoid, hand, foot and mouth disease, and influenza A H1N1.

In China's new law on the prevention and treatment of infectious diseases, infectious diseases are divided into three categories: A, B, and C, with a total of 39 types. Among them, there are two types of Class A infectious diseases, namely plague and cholera; There are 26 kinds of Class B infectious diseases, among which the common ones are atypical pneumonia, human infection with highly pathogenic avian influenza, AIDS, poliomyelitis, tuberculosis, anthrax, hepatitis B, diphtheria, tetanus, whooping cough, etc.; There are 11 types of Class C infectious diseases, and the common ones are epidemic disease, mumps, rubella, hand, foot and mouth disease, etc. Among them, SARS in Category B infectious diseases and pulmonary anthrax in anthrax shall be reported and managed in accordance with the reporting time limit for Category A transmission.

What is the classification of infectious diseases.

Respiratory tract infectious diseases: epidemic **, epidemic meningitis, tuberculosis, epidemic atypical pneumonia.

Digestive tract infectious diseases: cholera, bacillary dysentery, poliomyelitis, schistosomiasis, viral hepatitis, blood infectious diseases: AIDS, Japanese encephalitis, malaria, dengue fever, surface infectious diseases: acute conjunctivitis, trachoma.

Notifiable infectious diseases are divided into three categoriesThere are 39 species in total。Category A: 2 types, reported within 2 hours. Category B: 26 types, 24-hour reporting, Category C: 11 types, 24-hour reporting.

Infectious diseasesIt is a class of diseases caused by various pathogens that can be transmitted from person to person, animal to animal, or person to animal. Most of the pathogens are microorganisms, and a small part are parasites, which are also called parasitic diseases. For some infectious diseases, the epidemic prevention department must grasp the incidence of the disease in a timely manner and take countermeasures in a timely manner, so it should be reported to the local epidemic prevention department at the specified time and when it is suspected, which is called a notifiable infectious disease.

Class A infectious diseasesAlso known as compulsory management of infectious diseases, including: plague, cholera. The time limit for reporting the epidemic after the occurrence of such infectious diseases, the isolation of patients and pathogen carriers, the method of **, and the treatment of epidemic points and epidemic areas are all enforced.

Class B infectious diseasesAlso known as strictly managed infectious diseases, including: infectious atypical pneumonia, AIDS, measles, epidemic hemorrhagic fever, rabies, tuberculosis, typhoid and paratyphoid, influenza A (H1N1) (formerly known as human infection with swine flu), etc.

Category C infectious diseasesIt is also known as surveillance and management of infectious diseases, including: epidemic influenza, mumps, rubella, acute hemorrhagic conjunctivitis, leprosy, epidemic and endemic typhus, typhoid fever and infectious diarrheal diseases other than paratyphoid.

The Law on the Prevention and Treatment of Infectious Diseases also stipulates that the health administrative departments of *** and *** may, according to the circumstances, decide on the increase or decrease of infectious diseases according to their respective authority.
