Should sanitation tents be used for prevention of COVID-19 transmission?

ABSTRACT

Key Findings@#There is currently no evidence to support the use of sanitation tents in the prevention of COVID-19 transmission. • Sanitation tents or disinfection tents have been installed in various areas of the Philippines as a measure to decontaminate individuals and prevent COVID-19 transmission. • The commonly used disinfectant in these tents is diluted household bleach. Others propose to use alcohol or diluted povidone iodine to decontaminate individuals in the tent. • Bleach is an irritant to mucous membranes and loses its antimicrobial effect over time or when exposed to heat and sunlight. • Alcohol is flammable and also causes irritation to mucous membranes. • Povidone iodine may cause skin irritation, chemical pneumonitis when inhaled, and acute kidney injury when systemically absorbed. • There are no completed or ongoing studies on the use of sanitation tents for the prevention of COVID-19 transmission. • To date, there are no guidelines that recommend the use of sanitation tents for prevention of COVID-19 transmission. • The World Health Organization explicitly recommends against spraying alcohol or chlorine all over a person's body due to adverse health effects and the lack of inhibitory activity against viruses that have already entered the body. • The Centers for Disease Control and Prevention note that most environmental protection agency-registered household disinfectants are effective against COVID-19. However, these products are approved for use only on surfaces and not on humans. • The Department of Health guidelines recommend the avoidance of spraying or misting for COVID-19 due to lack of evidence of its efficacy.
