Preventive Healthcare Services01:30

Preventive Healthcare Services

2.3K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Standard Precaution01:26

Standard Precaution

3.3K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

737
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Healthcare Associated Infections II: Preventive Measures

4.8K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Levels of Health Promotion and Illness Prevention

15.4K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

2.1K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Public Health

Background:

  • Hepatitis B virus (HBV) infection is a significant global health concern, impacting millions worldwide and in the United States.
  • A large proportion of individuals with chronic HBV infection remain undiagnosed, hindering timely treatment and prevention of transmission.
  • HBV is transmitted through blood and body fluid exposure.

Purpose of the Study:

  • To highlight the prevalence of hepatitis B virus infection.
  • To emphasize the importance of screening and vaccination strategies.
  • To underscore the need for improved diagnosis and access to care for hepatitis B.

Main Methods:

  • Review of current recommendations for hepatitis B screening and vaccination.
  • Analysis of hepatitis B virus transmission routes and risk factors.
  • Assessment of vaccination rates and diagnostic awareness.

Main Results:

  • Up to 2.4 million in the US and 254 million globally have HBV infection.
  • Two-thirds of chronically infected individuals in the US are unaware of their diagnosis.
  • Current vaccination rates in US adults are low at 30%.

Conclusions:

  • Centers for Disease Control and Prevention recommends universal adult screening and vaccination for all age groups.
  • Screening during pregnancy is vital to prevent vertical transmission.
  • Eliminating hepatitis B in the US requires increased vaccination, diagnosis, and access to care.
