How many types of Class C infectious diseases are there

According to the "Law of the People's Republic of China on the Prevention and Control of Infectious Diseases", infectious diseases are divided into Class A infectious diseases, Class B infectious diseases and Class C infectious diseases. Category C mainly includes some common influenza, inflammation, etc. It is also known as testing to manage infectious diseases. For example, the common hand, foot and mouth disease is also included in the Class C infectious diseases. You may not be very familiar with these specific categories. Today I will tell you about several types of Class C infectious diseases.

Class C infectious diseases are also called monitored and managed infectious diseases, including: schistosomiasis, filariasis, echinococcosis, leprosy, influenza, mumps, epidemic and endemic typhus, rubella, acute hemorrhagic conjunctivitis, hand, foot and mouth disease, and infectious diarrheal infectious diseases other than cholera, amoebic dysentery, typhoid and paratyphoid. Class C infectious diseases must be managed in accordance with the monitoring and management methods prescribed by the health administrative departments of the State Council.

Schistosomiasis

Schistosomiasis is a parasitic disease that can infect both humans and animals. The life cycle of schistosoma is relatively complex. Adult worms live in the blood of the mesenteric vein and portal vein of humans, cattle, pigs or other mammals, so humans and these animals are called adult hosts or definitive hosts.

Filariasis

Filariasis is caused by filarial worms (a type of parasitic nematodes transmitted by blood-sucking arthropods) that parasitize the lymphatic system, subcutaneous tissue, abdominal cavity, thoracic cavity, etc. of the vertebrate definitive host. The clinical manifestations of filariasis caused by the two types of filarial worms are very similar. The acute phase is characterized by recurrent lymphangitis, lymphadenitis and fever, while the chronic phase is characterized by lymphedema and elephantiasis, which seriously endanger the health of residents in endemic areas and economic development.

influenza

Influenza (flu) is an acute respiratory infection caused by influenza virus. It is also a highly contagious and rapidly spreading disease. It is mainly transmitted through droplets in the air, contact between people or contact with contaminated objects. Typical clinical symptoms are: sudden onset of high fever, body pain, significant fatigue and mild respiratory symptoms. Generally, autumn and winter are the peak seasons for the disease, and the complications and deaths it causes are very serious.

rubella

Rubella (German measles), also known as "wind sha" and shazi, is a common respiratory infectious disease in children. Rubella is caused by rubella virus. The virus is present in the saliva and blood of the sick child 5 to 7 days before the rash appears, but it is difficult to find after 2 days of the rash. The rubella virus has very weak viability outside the body, but is as contagious as measles. It is usually spread through coughing, talking or sneezing. This disease is more common in children aged 1 to 5 years old. Infants under 6 months old rarely get the disease because they have immunity from antibodies from their mothers. Once you get the disease, you will be immune for life and rarely get it again.

Hand, foot and mouth disease

The English name is: Hand-foot-and-mouth disease. Hand, foot and mouth disease is an infectious disease caused by enterovirus. It mostly occurs in children under 5 years old. It can cause herpes on the hands, feet, mouth and other parts of the body. A small number of children may develop complications such as myocarditis, pulmonary edema, and aseptic meningoencephalitis. In some seriously ill children, if the disease progresses rapidly, it may lead to death. There are more than 20 types of enterovirus that can cause hand, foot and mouth disease. Coxsackievirus A group types 16, 4, 5, 9, 10, group B types 2 and 5, and enterovirus 71 are all common pathogens of hand, foot and mouth disease, among which Coxsackievirus A16 (Cox A16) and enterovirus 71 (EV 71) are the most common.

Note: The Infectious Disease Prevention and Control Law also stipulates that the State Council and the health administrative department of the State Council may decide to increase or decrease the types of infectious diseases based on their respective powers according to the circumstances.
