17 A form of quaternary prevention aims at identifying patients at risk of overmedicalisation. Many other regional initiatives (for example for the prevention of cancer with planned screenings) support this national plan. PREVENTION Prevention includes any action performed to keep people healthy and avoid risks of poor health, injury, and early death. Stages of a disease Any disease follows a natural path of five stages: underlying, when an individual may potentially develop a disease; susceptible, when an individual is at risk of developing a disease; subclinical, when there is a disease without apparent symptoms; clinical, when the disease shows its symptoms and is apparent; ONLINE RESOURCES Infections agents: bacteria, viruses and fungi Preventing the spread of contagious diseases recovery/disability/death, when the disease has run its course. Preventive stages Similarly, corresponding preventive health measures have been grouped into similar stages to prevent the natural progress of a disease. Primordial prevention aims at reducing risks and is targeted towards the whole population through laws and national policy. It addresses the underlying stage of natural disease by working on the social conditions that promote its potential onset, for example, by creating cycle lanes to promote physical activity and decrease risk factors for obesity. apparent: manifesto onset: principio outcome: esito pressure sore: piaga da decubito severity: gravit underlying: sottostante 40 BODY AND MIND Primary prevention focuses on measures aimed at preventing a disease from occurring and is targeted towards healthy individuals. It includes activities that limit risk exposure or increase the immunity of individuals at risk to avoid a disease from becoming subclinical, for example promoting vaccination campaigns. Secondary prevention works on the early detection of a disease and is targeted towards healthy-appearing individuals who may have developed a subclinical form of a disease. Screenings are typical examples of this type of prevention. Tertiary prevention covers both the clinical and the outcome stages of a disease. It targets symptomatic patients and aims at reducing the severity of the disease, pain, and possible complications, for example with medication and rehabilitation. Prevention in Italy In Italy, the government has implemented the Piano Nazionale della Prevenzione to deal with the following priority areas: non-transmissible chronic diseases; dependencies and related problems; street and home accidents; injuries and accidents at work; occupational diseases; environment, climate, and health; primary infectious diseases. Prevention in the UK In the UK, the National Health Service provides a prevention programme focused on: weight management and obesity; alcohol and tobacco dependencies; HIV prevention; tuberculosis; antimicrobial resistance; diabetes; cancer; cardiovascular diseases.
