Summary
Dental therapists in Zimbabwe demonstrate good infection control, but handpiece sterilization and eyewear use need improvement. Increased hepatitis B vaccination is recommended to prevent disease transmission.
Area of Science:
- Dental Public Health
- Infection Control
- Epidemiology
Background:
- HIV/AIDS transmission poses a significant risk in healthcare settings.
- Effective infection control practices are crucial for dental therapists.
- Assessing current practices in Zimbabwe is vital for targeted interventions.
Purpose of the Study:
- To evaluate general infection control practices among dental therapists in Zimbabwe.
- To specifically assess practices related to preventing HIV/AIDS transmission.
Main Methods:
- A descriptive, cross-sectional study was conducted.
- Self-administered questionnaires were used to gather data.
- Practices assessed included disinfection, sterilization, personal protection, and vaccination.
Main Results:
- A 68% response rate was achieved from dental therapists in government clinics.
- Universal glove use was reported, with high rates for masks and protective garments.
- However, significant gaps were identified in hepatitis B vaccination (91.7% unvaccinated) and HIV testing (20% tested).
- Barriers included the non-availability of essential supplies like gloves and disinfectants.
Conclusions:
- Dental therapists generally adhere to acceptable infection control measures.
- Areas for improvement include handpiece sterilization, consistent use of eyewear, and ensuring adequate disinfectant supplies.
- Promoting hepatitis B vaccination is essential for healthcare worker protection.

01:22Healthcare Associated Infections II: Preventive Measures
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.

01:26Standard Precaution
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.

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 progression...

01:23Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:25Transmission-based Precautions II: Airborne and Protective Environment
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...
