Infection prevention and control (IPAC) remains a highly effective, generic, global, and cost-effective means to mitigate virus spread. IPAC recommends proper disinfection of high-touch environmental surfaces (HITES) to reduce the risk of direct and indirect virus spread. The United States, Canada and many other countries mandate pre-market assessments of HITES disinfectants against viruses and other types of microbial pathogens. However, there are basic disparities in the regulation of disinfectants. Such incongruity in test protocols interferes with the determination of the true breadth of the microbicidal potential of a given product in the field where target pathogens are often unknown or may be encountered as mixtures. This review examines the various methodological disparities and recommends a more cohesive and harmonized approach.

The aim was to provide a baseline assessment of the IPC programme and activities within health care facilities in Malawi. Forty healthcare facilities were invited to participate.
