By 2024, contract janitorial services in the US are estimated at $8.6 billion, yet the pace of change is being driven just as much by healthcare infection control expectations as by routine cleaning volume. Hospital-linked HAIs remain a major risk, with about 1 in 25 hospitalized patients acquiring one during their stay, and the gap between poor and proven disinfection practices can be dramatic. This post pulls together the latest industry, workforce, and efficacy benchmarks, from projected market growth to real-world compliance and log reduction results.
