Prevention of primary infection |
|
behavioural modification |
decreased risk exposure, e.g. safe sex and decreased sex partners [25] and safe injecting drug use [26] |
education, e.g. cough hygiene [27] |
|
environmental modification |
decreased risk of occupational exposure through safe handling and disposal of sharps |
environmental measures to decrease nosocomial transmission [27,28] (particularly important where HIV prevalence is high) |
|
protect site of infection |
vaginal microbicides (under evaluation) [29] |
face masks (NN95 specification) [27] |
|
Modification of risk factors for infection |
|
promote decreased substance abuse |
decreased alcohol [30] and drugs [30] |
decreased alcohol [31] and smoking [32] |
|
detect and treat conditions associated with increased risk |
treatment of sexually transmitted infections [33] |
detection and management of diabetes [34] |
|
modify personal biological characteristic |
male circumcision [35] |
|
|
Drug prophylaxis |
|
pre-exposure |
pre-exposure prophylaxis (under evaluation) [36] |
isoniazid preventive treatment for infants born to mothers with tuberculosis [37] |
|
pre- and post-exposure |
prevention of mother to child transmission [38] |
|
|
post-exposure |
post-exposure prophylaxis [39] |
isoniazid preventive treatment for people with latent M. tuberculosis infection or for people at high risk of recurrent tuberculosis [40] |
|
Decreased transmission by treatment of infected individuals (treatment as prevention) [41] |
|
|
prompt diagnosis and effective treatment of people with symptomatic HIV-related disease [42] |
prompt diagnosis and effective treatment of people with symptomatic pulmonary disease [23] |
|
|
proposal for prompt diagnosis among asymptomatic individuals either through an individual seeking a test for HIV after an at-risk exposure or through regular universal testing [43] |
efforts aimed at decreasing diagnostic delay through community education, improved access to care, and improved quality of clinical care [44] |
|
Vaccination to prevent progression from infection to disease |
|
|
no vaccine yet available |
Bacille Calmette-Guerin (BCG) vaccination [45] |
