Environmental and decontamination issues for human coronaviruses and their potential surrogates

Area of Science:

• Virology and Public Health
• Infectious Disease Control
• Environmental Hygiene

Background:

• Coronaviruses (CoVs) pose significant public health challenges, necessitating a review of containment strategies.
• Previous research often used surrogate CoVs for decontamination and disinfection studies.
• Understanding CoV environmental stability and transmission is crucial for effective control.

Purpose of the Study:

• To review existing scientific knowledge on coronavirus containment.
• To translate findings into practical applications for COVID-19 decontamination and disinfection.
• To identify research gaps and recommend future directions.

Main Methods:

• Comprehensive literature review of studies on coronavirus containment, disinfection, and environmental stability.
• Analysis of factors influencing CoV survival, including temperature, humidity, and surface type.
• Evaluation of the efficacy of various chemical and physical agents against CoVs.

Main Results:

• CoVs spread via respiratory secretions, urine, and stool, with potential for airborne transmission.
• Viral stability is influenced by temperature, humidity, viral load, and surface type.
• CoVs are susceptible to radiation, extreme temperatures, pH, peroxides, halogens, aldehydes, solvents, and alcohols.

Conclusions:

• Effective COVID-19 containment requires understanding CoV environmental behavior and transmission dynamics.
• Disinfectants with multiple agents and optimal pH/temperature are most effective.
• Direct assessment of SARS-CoV-2 is essential, alongside patient/caregiver safety and broader pathogen control.
