Debate on MERS-CoV respiratory precautions: surgical mask or N95 respirators?

Area of Science:

• Infectious Diseases
• Public Health
• Epidemiology

Background:

• Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012, prompting global health concerns.
• Infection control recommendations for MERS-CoV have been debated, influenced by Severe Acute Respiratory Syndrome (SARS) experiences.
• Guidelines from international bodies show variability regarding respiratory precautions.

Discussion:

• A debate was held by the Infection Control Association (Singapore) and the Society of Infectious Disease (Singapore) on MERS-CoV respiratory precautions.
• The discussion focused on the evidence supporting the use of surgical masks for healthcare worker protection.
• Evolving understanding of MERS-CoV necessitates continuous evaluation of infection control strategies.

Key Insights:

• Surgical masks are presented as a potential protective measure for healthcare workers against MERS-CoV.
• Evidence supporting surgical mask efficacy in MERS-CoV settings is discussed.
• The need for clear, evidence-based guidelines for MERS-CoV infection control is highlighted.

Outlook:

• Further research may clarify optimal respiratory protection for MERS-CoV.
• Standardized infection control practices are crucial for managing MERS-CoV outbreaks.
• Continued dialogue among infectious disease experts is vital for refining public health recommendations.
