"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."
The study of communicable diseases caused by microorganisms.
Microorganisms: Types of microorganisms that cause infectious diseases, such as bacteria, viruses, fungi, protozoa, and helminths.
Pathogenicity: The ability of microorganisms to cause disease in a host.
Transmission: The methods through which infectious diseases are spread, including direct contact, airborne transmission, droplet transmission, and vector-borne transmission.
Epidemiology: The study of the distribution and determinants of infectious diseases in populations.
Immune response: The body's response to infectious agents, including the innate and adaptive immune systems.
Antibiotics: Pharmaceuticals used to treat bacterial infections, including types, mechanisms of action, and resistance.
Antiviral drugs: Pharmaceuticals used to treat viral infections, including types, mechanisms of action, and limitations.
Vaccines: Immunizations used to prevent infectious diseases, including types, delivery methods, and efficacy.
Public health: The science of protecting and improving the health of communities through education, policy, and disease surveillance.
Global Health: The study of health issues that transcend national borders, including infectious diseases.
Bacterial infections: Caused by bacteria, such as strep throat, tuberculosis, and urinary tract infections.
Viral infections: Caused by viruses, including common cold, influenza, and measles.
Fungal infections: Caused by fungi, such as ringworm, athlete's foot, and candidiasis.
Parasitic infections: Caused by parasitic organisms, including malaria, Giardia, and tapeworms.
Sexually transmitted diseases: Caused by bacteria, viruses or parasites that are transmitted through sexual contact such as HIV, Gonorrhoea and Syphilis.
Vector-borne diseases: Transmitted by vectors like mosquitoes, ticks and fleas, such as dengue fever, Zika virus, and Lyme disease.
Prion diseases: Caused by misfolded proteins, such as Creutzfeldt-Jakob disease.
Nosocomial infections: Infections that are contracted in healthcare facilities, such as MRSA, C. difficile, and surgical site infections.
Opportunistic infections: Infections that take advantage of a weakened immune system, such as pneumonia in HIV/AIDS patients.
Foodborne illnesses: Caused by contaminated food or water, such as salmonella and E.coli infections.
Zoonotic diseases: Transmitted from animals to humans, such as rabies, avian influenza, and West Nile virus.
Childhood infections: Infections typically contracted during childhood, such as chickenpox, mumps, and rubella.
Emerging infectious diseases: Newly identified infections, such as COVID-19, SARS, and Ebola.
"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."
