University of Arizona Study on Disinfecting Classrooms

Recently, Dr. Charles Gerba, professor of microbiology and immunology at the University of Arizona, commissioned a study on the role that contamination plays in disease transmission. Numerous studies have been conducted in the past which have taken a look at the role of disease transmission both from person to person as well as from inanimate surfaces to other people; however, given the current environment, this topic merits a closer look.

The Goals of the Study

For this reason, Dr. Gerba and his team at the University of Arizona conducted a study designed to analyze this topic in detail. The goals of the study included:

  • What is the effectiveness of electrostatic spraying on the transmission of pathogens?
  • What is the residual efficacy of Enviro-Master cleaning products when applied to a variety of fixtures?

These substances were applied in different settings including a heavily used university classroom, break rooms in offices, public restrooms, classroom desks, and restroom fixtures. After treating the aforementioned areas with an electrostatic sprayer, Enviro-Master’s Virus Vaporizer, trained research professionals analyzed the levels of bacteria in these environments.

The Results of the Study

In all three of these environments, the products were observed to have caused an immediate reduction in the total numbers of bacteria. Furthermore, the residual effects of these substances were profound. They kept the levels of bacteria low for five whole days.

The specific results are as follows:

  • Classroom: In the classroom environment, treatment reduced the levels of bacteria by 99.2 percent. Five days after treatment, the total numbers of bacteria decreased by 79.2 percent.
  • Coffee Break Room: In the coffee break room environmental, treatment led to a total of bacterial reduction of between 90.1 percent and 99.2 percent. Five days after treatment, it resulted in a decrease in the total numbers of bacteria of between 56.7 percent and 87.4 percent
  • Restroom: In the restroom environment, all touchpoints were treated. In summary, there were more bacteria present in women’s restrooms than men’s restrooms. The total bacterial reduction varied depending on the touchpoint itself. These included:
    • Bacterial reduction on toilet flush handles was between 89.6 percent and 99.8 percent
    • Bacterial reduction on sink counters was between 98.4 percent and 99.8 percent
    • Bacterial reduction on toilet stall exit handles was between 90.4 percent and 97.4 percent

Clearly, Enviro-Master’s disinfecting and sanitizing services are effective in reducing bacterial levels.

The Conclusions of the Study

The major conclusions of the study are as follows:

  • In all public locations studied, bacteria were reduced immediately after treatment.
  • The quantity of bacteria remained lower in all locations five days post-treatment.
  • Classroom desk treatment was highly effective in reducing bacteria.

It is critical for all organizations to take steps to reduce the spread of infections, particularly in educational environments.
