Antibiotic-resistant hospital acquired infections (HAIs) as well as other airborne infections are on the rise, according to the Center for Disease Control (CDC) and The World Health Organization (WHO). Many infections, such as chickenpox, influenza, measles, smallpox, SARS, tuberculosis etc. can be transmitted quickly through the air. Evidence for the airborne transmission of disease is also on the rise . Data exists to support the airborne nosocomial transmissions of Acinetobacter, Pseudomonas, and MRSA [6, 7, 8]. Airborne infectious diseases can spread rapidly and pervasively through a non-immune population . Infectious patients who are not isolated from the population can disperse these infectious airborne microorganisms in a wide geographical area through the air, which is inhaled by susceptible individuals who have had no direct contact with the primary source. This airborne spread becomes even more prevalent in healthcare settings because of overburdened hospitals and the presence of immunosuppressed patients.
Airborne infection isolation rooms, or AIIRs for short, are essential for the containment of highly contagious diseases . There are an increasing number of publications that emphasize the need for AIIRs since many hospitals have insufficient facilities to provide airborne infection isolation for large numbers of patients with airborne infectious diseases presenting quickly within a short period of time [3, 4]. Without adequate environmental controls, these patients will pose a risk to other patients and healthcare workers.
SteriSpace™ is an innovative air sterilization technology which can be deployed in various healthcare situations, providing clean air in a variety of medical settings. Negative Pressure can be maintained to prevent contamination of the environment from the air in a room where an infected patient is housed. Patients with a suspected infection of a highly contagious infectious disease (i.e. MDR-TB and XDR-TB, SARS, Ebola, measles, etc.) can be placed in isolation or be quarantined in a room where negative pressure is maintained. The airflow leaving the space is exhausted through a system using the SteriSpace™ technology, which has been shown to destroy bacteria or virus (>99.9999% as demonstrated in independent testing), preventing it from being released into the surrounding space or environment. When used in this manner, the SteriSpace™ technology solution satisfies the CDC Infection Control guidelines for infection isolation. This scalable and customizable design could minimize contamination and address the air quality challenges faced by healthcare facilities.
