Bacteria and viruses are frequently the main targets for disinfection processes. However, fungi can also present a major health hazard, so any decisions relating to disinfection processes and disinfectant choice should also address efficacy against fungi.
The most common fungal diseases are nail infections, vaginal Candidiasis, ringworm, and Candida infections of the mouth, throat, and oesophagus. Fortunately, many types of fungi do not normally cause infections in healthy people but can cause illness in immunocompromised people.
According to the US Centers for Disease Control and Prevention (CDC), the fungal diseases that affect people with weakened immune systems include Aspergillosis, Candida auris infection, Invasive candidiasis, Pneumocystis pneumonia (PCP), Candidiasis, Cryptococcus neoformans infection, Mucormycosis, Talaromycosis and Taloromyces.
Independent trials in 2023 have shown a greater than 4 log reduction in test organisms (Candida albicans,
Aspergillus brasiliensis and Saccharomyces cerevisiae) by Hypochlorous Acid at 410ppm (Nemesis eH2O ready-to-use solution is 500ppm).
A further trial with an added interfering substance (to mimic dirt) showed a greater than 4 log reduction at a concentration of around 1000ppm. Please note that Nemesis eH2O is also available at 1000ppm.
