What is an infectious disease? What's the difference between infectious diseases and infectious diseases?

Infectious diseases refer to infectious diseases caused by pathogenic microorganisms, such as prions, viruses, chlamydia, rickettsia, mycoplasma, bacteria, fungi, spirochetes and parasites, such as protozoa, worms and medical insects, which can cause epidemics under certain conditions, such as influenza and severe acute respiratory syndrome (SARS).

The similarities between infectious diseases and infectious diseases are all caused by pathogens, and infectious diseases are a special type of infectious diseases; Infectious diseases include not only infectious diseases, but also many non-infectious diseases, such as abdominal infection, ventilator-associated pneumonia and infective endocarditis. Especially in recent years, infections caused by multi-drug resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Enterobacteriaceae (CRE) have gradually developed into clinical refractory diseases, which has become a great challenge for clinical diagnosis and treatment. With the change of infectious disease spectrum, "infectious diseases" gradually replaced "infectious diseases".

After three typical periods, the early infectious diseases department has developed into today's "infectious diseases department version 3.0" "Infectious Diseases Department 1.0 Edition" is a traditional infectious diseases department, which mainly treats infectious diseases such as epidemic cerebrospinal meningitis, epidemic Japanese encephalitis, typhoid fever, measles and viral hepatitis. "Infectious Diseases Department Version 2.0" unifies the fever clinic, intestinal clinic, respiratory clinic and infectious diseases department established during SARS into infectious diseases department according to the requirements of the Notice of the Ministry of Health on the Construction of Infectious Diseases Department in General Hospitals above Grade II in 2004. With the increase of multidrug-resistant bacteria, the mortality caused by drug-resistant bacteria is on the rise rapidly. The urgent task is to establish a professional department that can adapt to the changes of infectious diseases spectrum and conform to the international trend, and cultivate professionals with knowledge and ability of bacterial and fungal infections and antibacterial drug application. In 20 16, the national health and family planning commission issued the notice on improving the diagnosis and treatment ability of bacterial and fungal infections in general hospitals above grade 2 (hereinafter referred to as the notice), which will play a positive role in the rational use of antibacterial drugs and even the development of infectious diseases. In this context, the infectious diseases department version 3.0 came into being.
