"Infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce."
This branch of medicine deals with the diagnosis and treatment of infectious diseases.
Microbiology: The study of microscopic organisms, including bacteria, viruses, fungi, and parasites, and their interaction with humans.
Immunology: The study of the immune system, including how it defends the body against pathogens and how it can be manipulated to treat disease.
Epidemiology: The study of patterns, causes, and effects of infectious diseases in populations.
Pathology: The study of the underlying causes and mechanisms of diseases.
Pharmacology: The study of how drugs interact with or affect the body, including antibiotics and antivirals.
Clinical infectious disease: The application of medical knowledge and techniques to the diagnosis, treatment, and prevention of infectious diseases.
Public health: The prevention and management of infectious diseases in populations, including vaccine development, public health campaigns, and outbreak investigations.
Global health: The study of health issues that affect people around the world, including infectious diseases that are prevalent in developing countries.
Travel medicine: The study of health risks related to travel, including infectious diseases that may be encountered in different parts of the world.
Hospital epidemiology: The prevention and control of infections in hospital settings, including the use of isolation protocols and infection control practices.
Medical microbiology: The laboratory study of microorganisms, including the identification of pathogens and antibiotic sensitivity testing.
Zoonoses: Infectious diseases that can be transmitted from animals to humans.
Infection control: The prevention of the spread of infectious diseases in healthcare, community, and home settings.
Sexually transmitted diseases (STDs): Infectious diseases that are primarily transmitted through sexual contact, including HIV/AIDS, gonorrhea, and chlamydia.
Emerging infectious diseases: Newly identified or previously unknown infectious diseases that are appearing or reappearing in populations.
Bacteriology: This is the study of bacteria and their effects on the human body. It includes the identification and treatment of bacterial infections like pneumonia, meningitis, and tuberculosis.
Virology: This is the study of viruses and their effects on the human body. It includes the identification and treatment of viral infections like influenza, hepatitis, and HIV/AIDS.
Parasitology: This is the study of parasites and their effects on the human body. It includes the identification and treatment of parasitic infections like malaria, leishmaniasis, and worm infections.
Mycology: This is the study of fungi and their effects on the human body. It includes the identification and treatment of fungal infections like ringworm, oral thrush, and fungal meningitis.
Immunology: This is the study of the immune system and its response to infections. It includes the identification and treatment of immunodeficiency disorders, autoimmune disorders, and allergies.
Epidemiology: This is the study of the patterns and causes of infectious diseases in populations. It includes the identification and control of outbreaks of infectious diseases and the development of vaccines.
Travel Medicine: This is a specialized field of medicine that focuses on the health risks associated with travel. It includes the identification and prevention of travel-related infectious diseases like malaria, dengue fever, and yellow fever.
Public Health: This is the study of the health of populations and the prevention of infectious diseases through public health interventions like vaccination programs, sanitation measures, and infection control.
Infection Control: This is the practice of preventing the spread of infectious diseases in healthcare settings. It includes the identification and control of outbreaks of hospital-acquired infections and the implementation of infection prevention measures.
Tropical Medicine: This is a specialized field of medicine that focuses on the health issues that affect populations living in tropical regions. It includes the identification and treatment of tropical diseases like dengue fever, malaria, and Chagas disease.
"An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection."
"Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses."
"Hosts can fight infections using their immune systems."
"Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response."
"Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics."
"Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths)."
"The branch of medicine that focuses on infections is referred to as infectious diseases."
