  • Environmental disinfection against COVID-19 in different areas of health care facilities: a review

    The coronavirus disease 2019 (COVID-19) originated in bats and human-to-human transmission through respiratory droplets and contact with surfaces of infected aerosol are the main ways of transmitting this virus.


    Until now, there is no effective pharmaceutical treatment; conclusively it is important to evaluate the types of applied disinfectants in different areas against Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2), the virus that causes COVID-19.


    The aim of this review was to summarize the information about environmental disinfection for preventing of COVID-19. We performed a review of the science direct database to find articles providing information on disinfection used for SARS-CoV-2.


    The extracted results were given the original data on inactivation coronaviruses by disinfectants in different places of health care facilities. The final search recognized that five groups of disinfectants include: chlorine containing disinfectants, alcohol, UV irradiation, Hydrogen peroxide, and other disinfectant were used against SARS-CoV-2 in different environments. Among these groups, bleach (chlorine containing disinfectants) has the most applicability. Also, in many studies by using disinfectants with 62-71% ethanol can reduce coronavirus in contaminated areas. Furthermore, after the using of operating room for COVID-19 patients, hydrogen peroxide and UV irradiation should be used for 24 h before it can be used again.


    The povidone-iodine or the chlorhexidine, could be recommended when there is a risk of SARS-CoV-2 contamination especially for open wounds. According to the different studies on SARS-CoV-2 disinfection, because of the SARS-CoV-2 can remain in the air and on surfaces, as well as observing individual disinfection guidelines in different hospital areas, disinfection of surfaces is necessary to decrease SARS-CoV-2 spreading. Moreover, the most suggested disinfectants have been limited to bleach and alcohol, it’s better to be considered the potential of other disinfectants in different areas.

      Is 0.5% hydrogen peroxide effective against SARS‐CoV‐2?

      SARS‐CoV‐2 is mostly transmitted through respiratory droplets and contact routes, but the WHO also states that “airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed”.
