The COVID-19 virus, SARS-CoV-2, can be killed or inactivated on surfaces and in air by several methods, though inside the human body it is fought by the immune system and medical treatments. On surfaces, EPA-registered disinfectants effective against coronaviruses include diluted bleach solutions, quaternary ammonium compounds, hydrogen peroxide products, and seventy percent alcohol solutions when used with proper contact time and ventilation. Soap and water works by breaking apart the virus's lipid envelope and lifting it from hands and surfaces for removal. Heat above certain thresholds, such as washing laundry in hot water, also inactivates the virus. Ultraviolet germicidal irradiation can inactivate viruses in air and on surfaces when properly designed. Inside the body, the immune response clears the virus, and for high-risk patients healthcare providers may prescribe antiviral medications. Vaccination does not kill the virus on surfaces but helps the immune system respond. Always follow product labels and public health guidance for safe and effective use.
