Coronaviruses are transmitted from an infectious individual through large respiratory droplets generated by coughing, sneezing or speaking. These infectious droplets are then transmitted to the mucosal surfaces of a recipient through inhalation of the aerosol or by contact with contaminated fomites such as surfaces or other objects. In healthcare settings, personal protective equipment (PPE) plays a crucial role in interrupting the transmission of highly communicable diseases such as COVID19 from patients to healthcare workers (HCWs). However, research has shown that PPE can also act as a fomite during the donning and doffing process as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can survive on these surfaces for up to three days. This creates a need for more effective PPE materials that can provide antiviral protection. In this proposal we aim to develop a dual action antiviral/antifouling coating to lower the risk of transmission of the SARS-CoV-2 to HCWs from COVID19 patients. This project will deliver antiviral/antifouling coatings that can be readily applied to PPE surfaces such as faceshields that are likely to encounter a high level of viral load and would be of great benefit to the health of clinical staff. Furthermore, this project has embedded into its planning a rapid pathway for optimisation, translation, and upscaling of manufacture to deliver a low-cost technology within a short timescale.
