OBJECTIVE: In the current absence of a vaccine for COVID-19, public health
responses aim to break the chain of infection by focusing on the mode of
transmission. We reviewed the current evidence on the transmission dynamics and
on pathogenic and clinical features of COVID-19 to critically identify any gaps
in the current infection prevention and control (IPC) guidelines. METHODS: In
this study, we reviewed global COVID-19 IPC guidelines by organizations such as
the World Health Organization (WHO), the US Centers for Disease Control and
Prevention (CDC), and the European Centre for Disease Prevention and Control
(ECDC). Guidelines from 2 high-income countries (Australia and United Kingdom)
and from 1 middle-income country (China) were also reviewed. We searched
publications in English on 'PubMed' and Google Scholar. We extracted information
related to COVID-19 transmission dynamics, clinical presentations, and exposures
that may facilitate transmission. We then compared these findings with the
recommended IPC measures. RESULTS: Nosocomial transmission of SARS-CoV-2 in
healthcare settings occurs through droplets, aerosols, and the oral-fecal or
fecal-droplet route. However, the IPC guidelines fail to cover all transmission
modes, and the recommendations also conflict with each other. Most guidelines
recommend surgical masks for healthcare providers during routine care and N95
respirators for aerosol-generating procedures. However, recommendations regarding
the type of face mask varied, and the CDC recommends cloth masks when surgical
masks are unavailable. CONCLUSION: IPC strategies should consider all the
possible routes of transmission and should target all patient care activities
involving risk of person-to-person transmission. This review may assist
international health agencies in updating their guidelines.
