INTERNATIONAL CONFERENCE

HOUSING, HEALTH AND EXTREME EVENTS:

DEVELOPING GOOD PRACTICE AND SOUND POLICY

Parallel Session E 14.50

Helen Onyeaka and Taghi Miri

School of Chemical Engineering, University of Birmingham

As extreme weather events, such as floods, hurricanes, and heatwaves, increase in frequency and severity, ensuring the health and safety of affected populations has become critical. These events often lead to significant disruptions in housing, healthcare, and sanitation systems, creating environments that heighten the risk of infections and disease outbreaks. The rise of antimicrobial resistance (AMR) further compounds these risks, necessitating innovative approaches to microbial control, particularly in temporary shelters, healthcare facilities, and public spaces established during post-event recovery.

Biovitae light technology, which operates within the visible spectrum, has emerged as a promising tool in combating microbial contamination in such settings. Unlike ultraviolet (UV) light, which can harm human skin and eyes, Biovitae light is safe for human exposure while effectively deactivating a broad range of pathogens. Through the photoexcitation of porphyrin molecules in microorganisms, Biovitae induces the production of reactive oxygen species, leading to cellular damage and microbial death. Its efficacy has been demonstrated against bacterial pathogens, including Escherichia coli, Bacillus cereus, and Listeria monocytogenes, across surfaces such as stainless steel and glass - common in emergency shelters and medical facilities.

Given its effectiveness in inactivating biofilms and multidrug-resistant strains, Biovitae light represents a scalable, environmentally friendly solution for infection control during extreme events. This case study explores its application in temporary housing and healthcare environments, focusing on its potential to reduce infection risks in the immediate aftermath of disasters. As extreme events challenge global health systems, integrating innovative technologies like Biovitae light into post-event recovery plans can significantly improve health outcomes and contribute to more resilient and safer living environments.

Further research is needed to explore its long-term applications in disaster-stricken communities and optimize its use across varied environmental conditions.
