Nosocomial infection control in healthcare settings: Protection against emerging infectious diseases

Area of Science:

• Infectious Diseases
• Epidemiology
• Public Health

Background:

• The 2015 Middle East respiratory syndrome (MERS) outbreak in South Korea was potentially linked to inadequate nosocomial infection control.
• Emerging infectious diseases, including MERS, Ebola virus disease, and severe acute respiratory syndrome (SARS), pose significant challenges to healthcare infection control.
• Clusters of emerging or unknown infectious diseases often manifest in healthcare settings before definitive identification or community transmission.

Discussion:

• Healthcare-associated infections (HAIs) are a persistent concern, particularly with novel pathogens.
• The effectiveness of infection control protocols is paramount in preventing secondary transmission within hospitals.
• Lessons from past outbreaks underscore the need for continuous evaluation and improvement of infection control strategies.

Key Insights:

• The MERS outbreak in Korea suggests that lapses in hospital infection control can facilitate disease spread.
• Strict adherence to infection control measures, as demonstrated in a southern China hospital, can effectively prevent MERS-CoV transmission among healthcare workers.
• Proactive and rigorous infection control is crucial for managing imported cases of highly contagious diseases.

Outlook:

• Enhanced surveillance and rapid response systems are necessary to mitigate the impact of future emerging infectious disease outbreaks.
• Investment in training healthcare workers on infection control protocols for novel pathogens is vital.
• Further research into optimal infection control strategies for MERS and other emerging respiratory viruses is warranted.
