Transmission route(Kansen Keiro,British: route of infection) IsinfectionPresent in the individual or environment that caused thePathogen, Is a route to reach an uninfected individual and cause a new infection. Depending on the pathogen, infection may occur via multiple routes of infection.EpidemicOutbreaks such asNosocomial infection Ofpreventionな どInfection controlAbove isPathogenFind outSource of infectionIt is important to find out, but above all, it cannot be completed unless the infection route is cut off.
- Airborne infection-Microparticles (0.5 μm or less) stay in the air for extended periods of time and continue to contaminate even after the patient leaves.
- Droplet infection-Small moist particles (0.5 μm or larger) remain in the air for a short period of time. Usually infected with the patient.
- Direct infection-by touching the infected patient directly. Including sexual contact.
- Indirect infection-by touching contaminated soil.
- Fecal Mouth Path-Unwashed hands, contaminated plants and water sources.
Main infection routes
- Infected belowRouteOf infectious diseases inAn exampleIs mentioned, but the infection route isMultipleIt should be noted that there may be cases and there is no one-to-one relationship.
Splash nuclear infection,Dust infection,Aerosol infectionand so on.English is airborne transmission(Air-mediated propagation), abbreviatedAirborneAlso called.Airborne infections are simply infectiousaerosolPropagate throughFrom the standpoint of being infected, In the aerosolLimited to propagation by droplet nuclei(Splash nuclear infection).
According to the International Epidemiological SocietyEpidemiologyThe dictionary adopts the former definition, which defines that microbial aerosols are transmitted by entering the respiratory tract.Examples include droplet nuclear infection and dust infection.Chemical Society of JapanJapanese standard byChemicalIn the dictionary (2nd edition), aerosol (also translated as aerosol) is a general term for a state in which solid or liquid fine particles are dispersed and suspended in a gas, such as smoke or fog. Solid or liquid in a dispersion medium whose state is gasColloidal particlesDispersedSolIt was named aerosol because it was regarded as a kind of aerosol. "a.
Droplet nuclear infection is infectiousPathogenDroplet nuclei includingdroplet nuclei: Refers to those that diffuse through the evaporated droplet residue)..These pathogens maintain infectivity in vitro for long periods of time.Moisture evaporates in the air 5MicrometerThe following light particles (droplet nuclei) that still retain their infectivity remain suspended in the air for a long period of time, 3フ ィ ー ト(91Centimeter) Travel longer distances and infect others via the upper and lower respiratory tract..Particles in the air are less than 5 micrometers..This generally requires a high level of isolation.Therefore, a negative pressure environment is required to avoid pollution.
tuberculosis,Varieg,measles,smallpox,Herpes zoster[Annotation 1]Etc. are airborne (droplet nuclear infection).These are often in the wardNosocomial infectionTo causeInfection controlIs an important disease.influenza,CoronavirusThere is always debate as to whether such infections cause airborne infections (strictly speaking, aerosol infections) or are the main transmission routes..
English is droplet transmission(Small drop infection).This is due to respiratory droplets that occur during coughing, sneezing, conversation, etc., and is a common route of infection.Due to the large droplets, they cannot float in the air for long periods of time and are usually scattered at close range...Splash particles are 5 micrometers or more..Infection by droplets can occur when it adheres to the surface of sensitive mucous membranes such as the eyes, nose, and mouth, or when it touches the face with a hand that touches the contaminated surface.
Respiratory infectious disease pathogens transmitted by dropletsInfluenza virus,Parainfluenza virus,Adenovirus,Rhinovirus,RS virus,Human metapneumovirus,Pertussis,Pneumococcus,Streptococcus pyogenes,diphtheria,rubella,CoronavirusCan be mentioned..Splash diffusion can be reduced by wearing a surgical mask.
If the amount of virus contained in the droplets of an infected person is high, it is observed as if it were an airborne infection (strictly speaking, it corresponds to an aerosol infection)..
Contact infectionAlso called.English is direct contact(Direct contact).Infection is caused by direct contact between living organisms carrying pathogens.
It typically refers to skin-to-skin contact, kissing, and sexual intercourse.It also refers to contact with soil and plants containing pathogens..Faeces routeIs mainly regarded as an indirect contact route, but in some cases, it is transmitted by direct contact with feces.
Infection occurs when the infected person's blood or body fluid adheres to the mucous membranes of the eyes and nose.Transmission routes can be direct or indirect through vectors.It may be included in the next transdermal infection.
Epidemic keratoconjunctivitisOphthalmic diseases such as.
Normally, the skin has the ability to prevent the invasion of pathogens, but the pathogens invade the body by being bitten or bitten by mosquitoes, insects, or dogs.Parasites may invade the body directly through the skin.In addition, pathogens invade from areas where the protective function of the skin has been lost due to wounds and burns.Especially theseTranscutaneous infectionMay be called.Needlestick accidents are also included in percutaneous infections.
Blood infection(Cross infection) Tomo.Injection ortransfusion,such asMedicalIn addition to actions, bleeding due to trauma touches mucous membranes such as the eyes of others, causing infection of pathogens in the blood.Again, the route of infection can be direct or indirect through a vector.
- MRSA,HIV,Hepatitis B,Hepatitis C,Creutzfeldt-Jakob diseaseIs typical.
- If there is a large amount of exposuresyphilisIs also considered.
It is a sexual contact infection.There are aspects of mucosal and oral infections.
Especially when pathogens in saliva are transmitted by mouth transfer or deep kiss through saliva.Saliva infectionIt may be said.According to the clinical transmission route classification theory, plaque infection and breath infection are included in oral infection, but saliva infection is not included.Caries fungus,EB virusSaliva infection occurs due to such factors.
Both mother-to-child transmission and vertical transmission.It is further classified as follows.
- In utero infection (transplacental infection/transamniotic fluid infection): placentaPass throughbloodInfection through.rubellaVirus,Human immunodeficiency virus(HIV),Cytomegalovirusetc.
- Birth infection (transvaginal infection): Infection via bleeding at birth and abrasions on the skin. B typehepatitis,HIVetc.
- Breast milk infection: HIV,Adult T-cell leukemia virusetc.
Indirect contact infection(Indirect contact transmission, vehicle-borne transmission) is a route transmitted by contact with non-living organisms.Examples include food, water, biological products (blood, etc.), mediators (handkerchiefs, bedding, surgical scalpels), etc.For example, improperly manufactured canned foodsClostridium botulinumbyBotulinum toxinIt provides an environment suitable for production.
Especially for infections through food and drink contaminated with pathogensOral infectionMay be called.If the cause of pollution is fecesInfection(Faeces route, See below).In addition, food and drink itself becomes a source of infection and is transmitted orally.BSEThere is.
Vector infection (horizontal transmission)
Other animals (especiallyArthropod) Becomes a vector (vector), and the infection is established by transmission. (1) As part of the life cycle of the pathogen, when the vector grows and propagates in the body and is infected from it (biological transmission), (2) the pathogen simply attached to the body surface of the vector is mechanically It may be transmitted (mechanical transmission, mechanical vector infection).
- The example of (1) isMosquitoesbyDengue fever,Japanese encephalitis,West Nile fever,yellow fever,malariaInsect-borne infections, such asTickbyCrimean Congo hemorrhagic fever,Severe febrile thrombocytopenia syndrome(SFTS) mediation,LousebyTyphusMedium ofA mousebyLassa fever,South American hemorrhagic fever,Hantavirus,Plague,typhoid,Paratyphoid,SalmonellaIntermediary such as.
- The example of (2) isFliesEnterohemorrhagic E. coli andShigellaMedium ofbird-fluInter-house vector.
InfectionAlso called.It may also be regarded as a type of oral infection (water-borne infection, water-borne epidemic).
Infection is established by ingestion of food and drink contaminated with feces.
Enterohemorrhagic Escherichia coli(Such as O157),Staphylococcus,Vibrio parahaemolyticus,Clostridium botulinum,Salmonella,typhoid,Paratyphoid,Bacillary dysentery,cholera,Campylobacter,Listeria,Helicobacter pylori,Amoeba dysentery,Norovirus,Rotavirus,Polio,Hepatitis A,Hepatitis E,Weyl's disease,Keratoconjunctivitisetc.
Identification of infection route
When the pathogen can be identified
Wipe the surfaces of handrails and medical equipment shared by patientscultureHowever, if a pathogen is detected, it is presumed that the object is one of the infection routes. In addition, in the case of bacterial infections,Pulse field gel electrophoresisWhen the closeness of the genotype is examined byHorizontal infectionSince the temporal order of can be estimated, it is not uncommon to find out how the pathogen was first introduced into the population.
When the pathogen cannot be identified
EarlySARSIf the pathogen cannot be identified, as described above, the sick and healthy individuals are first isolated, and detailed information is collected on their behavior patterns, life backgrounds, and contact history with others. Among them, factors that correlate with the presence or absence of infectionEpidemiologyInfected routes are estimated by identifying them.
Example: If multiple people in the same room away from the sick person are affected, it is suspected that a droplet nuclear infection (air infection) occurs.
