| subclinical infection | <epidemiology> An infection in which symptoms are sufficiently mild or inapparent to escape diagnosis other than by positive confirmation of the ability to transmit the infection or serologically. (05 Dec 1998) |
| nosocomial infection | <microbiology> Hospital acquired infection: commonest are due to Staphylococcus aureus, Pseudomonas aeruginosa, E. Coli, Klebsiella pneumoniae, Serratia marcescens and Proteus mirabilis. (18 Nov 1997) |
| surgical wound infection | Infection occurring at the site of a surgical incision. (12 Dec 1998) |
| disseminated gonococcal infection | Infection from Neisseria gonorrhoea which is spread to distant parts of the body beyond the original portal of entry (usually the lower genital tract). Usually manifest by rash and arthritis. (05 Mar 2000) |
| droplet infection | Infection acquired through the inhalation of droplets or aerosols of saliva or sputum containing virus or other microorganisms expelled by another person during sneezing, coughing, laughing, or talking. (05 Mar 2000) |

| infection | 1. <microbiology> Invasion and multiplication of microorganisms in body tissues, which may be clinically unapparent or result in local cellular injury due to competitive metabolism, toxins, intracellular replication or antigen antibody response. The infection may remain localised, subclinical and temporary if the bodys defensive mechanisms are effective. A local infection may persist and spread by extension to become an acute, subacute or chronic clinical infection or disease state. A local infection may also become systemic when the microorganisms gain access to the lymphatic or vascular system. 2. An infectious disease. (18 Nov 1997) |

| infection control | Programs of disease surveillance, generally within health care facilities, designed to investigate, prevent, and control the spread of infections and their causative microorganisms. (12 Dec 1998) |
