English

Subject field(s)
  • Epidemiology
  • Human Diseases - Various
  • Animal Diseases
OBS

The chain of transmission of infection is composed of six links : the infectious agent, the reservoir, the portal of exit, the mode of transmission, the portal of entry and the susceptible host.

  • Maladies humaines diverses
  • Maladies des animaux
OBS

La chaîne de transmission de l'infection est composée de six maillons : l'agent infectieux, le réservoir, la porte de sortie, le mode de transmission, la porte d'entrée et l'hôte réceptif.

Spanish

Campo(s) temático(s)
  • Epidemiología
  • Enfermedades humanas varias
  • Enfermedades de los animales
CONT

La ocurrencia de las enfermedades infecciosas obedece a una secuencia de interacciones que permiten que el microorganismo infectante se ponga en contacto con una persona susceptible y produzca en ella la infección. Las infecciones son resultado de estas interacciones con un microorganismo que deja su hábitat para reproducirse en un huésped (individuo reservorio). Luego, se trasmite hacia otros individuos pasando por una puerta de salida (vía para transmitirse desde el huésped, mecanismo de transmisión) y encuentra una puerta de entrada (canal de infección, vía de infección) en un nuevo individuo (huésped susceptible). Esta secuencia de eventos específicos se conoce como "cadena de transmisión" […]

Record 2 2021-06-16

English

Subject field(s)
  • Epidemiology
  • Microbiology and Parasitology
DEF

The anatomic site at which an infectious agent enters a host’s body.

CONT

More specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection.

OBS

For example, the mucous membranes of the nose or mouth and skin lesions can be portals of entry.

French

Domaine(s)
  • Épidémiologie
  • Microbiologie et parasitologie
DEF

Site anatomique où un agent infectieux pénètre dans le corps d'un hôte.

CONT

La porte d'entrée est variable selon l'agent infectieux [...]

OBS

Par exemple, les muqueuses du nez ou de la bouche ainsi que des lésions cutanées peuvent être des portes d'entrée.

Record 3 2013-08-01

English

Subject field(s)
  • Vessels (Medicine)
CONT

Infection via the portal system(portal pyemia) : The infectious process originates within the abdomen and reaches the liver by entering the portal vein. Appendicitis and pylephlebitis are the predominant causes. However, any source of intra-abdominal abscess, such as acute diverticulitis, inflammatory bowel disease, and perforated hollow viscus, can lead to portal pyemia and hepatic abscesses.

Record 4 2011-10-04

English

Subject field(s)
  • Bacterial Diseases
DEF

A fulminating bacterial infection with group A streptococci, beginning with extensive cellulitis that rapidly spreads to involve the superficial and deep fascia, producing thrombosis of subcutaneous vessels and gangrene of the underlying tissue.

OBS

A cutaneous lesion often serves as a portal of entry for the infection.

OBS

The streptococcal toxic shock syndrome accompanies the flesh-eating disease and has 81% mortality rate.

Key term(s)
  • flesh eating disease

French

Domaine(s)
  • Maladies bactériennes
DEF

Infection des fascias hypodermiques évoluant très vite vers la nécrose, due à une association de bactéries anaérobies et de streptocoques de pronostic sévère.

Record 5 2006-11-28

English

Subject field(s)
  • Immunology
  • Epidemiology
DEF

A direct and essentially immediate transfer of infectious agents to a receptive portal of entry through which human or animal infection may take place.

OBS

This may be by direct contact (for example: touching, biting, kissing, sexual intercourse) or by direct projection (droplet spread) of droplet spray onto the conjunctiva or onto the mucous membranes of the eye, nose, or mouth during sneezing, coughing, spitting, singing, or talking (usually limited to a distance of about 1 meter or less).

French

Domaine(s)
  • Immunologie
  • Épidémiologie
CONT

Les fermes avicoles et les marchés où l'on vend des animaux vivants, comme des poulets et des canards [...] sont des vecteurs potentiels du virus de l'influenza aviaire. Les recherches ont démontré que le risque de transmission directe du virus H5N1 des oiseaux aux humains est plus grand lorsque ces derniers ont des contacts étroits avec la volaille vivante infectée.

Spanish

Campo(s) temático(s)
  • Inmunología
  • Epidemiología
DEF

Transferencia del agente etiológico sin presencia de vehículos.

CONT

Una enfermedad es transmisible cuando un hospedador infectado puede transmitir el agente infeccioso a otro hospedador y establecer la infección en este hospedador. La transmisión del agente puede ser directa o indirecta. Directa es cuando existe contacto con el hospedador infectado. Indirecta cuando el agente infeccioso pasa a través de un objeto o sustancia intermedia.
