Identifying Contact Risks for SARS-CoV-2 Transmission to Healthcare Workers during Outbreak on COVID-19 Ward
Emerging Infectious Diseases
|August 24, 2022
Summary
Working with isolated COVID-19 patients did not increase SARS-CoV-2 risk for healthcare workers. However, shifts with presymptomatic coworkers significantly elevated COVID-19 infection risk among hospital staff.
Area of Science:
- Infectious Disease Epidemiology
- Occupational Health and Safety
- Viral Transmission Dynamics
Background:
- Assessing SARS-CoV-2 exposure risks in healthcare settings is crucial for infection control.
- A late 2020 COVID-19 outbreak on a hospital ward provided a unique opportunity to study transmission.
- Understanding transmission pathways among healthcare workers (HCWs) is vital for pandemic response.
Discussion:
- Direct patient contact with isolated COVID-19 cases did not correlate with increased HCW infection.
- Working alongside presymptomatic infected colleagues emerged as a significant risk factor for SARS-CoV-2 acquisition.
- This highlights the challenge of asymptomatic and presymptomatic transmission in occupational settings.
Key Insights:
- Presymptomatic transmission poses a substantial risk in healthcare environments.
- Current isolation protocols for confirmed cases may be effective, but presymptomatic spread remains a concern.
- Targeted interventions focusing on early detection and management of presymptomatic individuals are needed.
Outlook:
- Further research should investigate the specific mechanisms of presymptomatic transmission among HCWs.
- Enhanced surveillance and rapid testing strategies could mitigate risks associated with presymptomatic coworkers.
- Implementing robust infection prevention and control measures is essential to protect healthcare personnel during outbreaks.

Standard Precaution
2.1K
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...

Transmission-based Precautions II: Airborne and Protective Environment
1.4K
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...

Healthcare Associated Infections II: Preventive Measures
2.8K
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.

Hand hygiene
3.7K
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.

PPE Use in Healthcare Settings I: Donning
1.2K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
