Preventive healthcare, or prophylaxis, is the application of healthcare measures to prevent diseases. [1] Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes that begin
These investigations are carried out in order to prevent additional cases in the current outbreak, prevent future outbreaks, learn about a new disease or learn something new about an old disease. Reassuring the public, minimizing the economic and social disruption as well as teaching epidemiology are some other obvious objectives of outbreak ...
During the 2002–2004 SARS outbreak, the SARS-CoV-1 virus was prevented from causing a pandemic of Severe acute respiratory syndrome (SARS). Rapid action by national and international health authorities such as the World Health Organization helped to slow transmission and eventually broke the chain of transmission, which ended the localized epidemics before they could become a pandemic.
Widespread immunization has substantially reduced the morbidity and mortality rates from diseases such as tuberculosis, poliomyelitis, measles, diphtheria, tetanus, pertussis, hepatitis B, yellow fever, meningitis A and many others. Recent innovations have expanded the impact of vaccines in addressing not only childhood diseases but also adult ...
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
The 3-4-50 concept [5] outlines that there are 3 behaviors (poor diet, little to no physical activity, and smoking), that lead to four diseases (heart disease/stroke, diabetes, cancer, pulmonary disease), that account for 50% of deaths worldwide. This is why so much emphasis in public health interventions have been on changing behaviors or ...
The Immunization Surveillance, Assessment and Monitoring program of the WHO monitors and assesses the safety and effectiveness of programs and vaccines at reducing illness and deaths from diseases that could be prevented by vaccines. [5] Vaccine-preventable deaths are usually caused by a failure to obtain the vaccine in a timely manner.
Predictive medicine is a field of medicine that entails predicting the probability of disease and instituting preventive measures in order to either prevent the disease altogether or significantly decrease its impact upon the patient (such as by preventing mortality or limiting morbidity).
