Treatments effective against coronavirus include steam and heat. The virus is susceptible to many active ingredients (AI), such as sodium hypochlorite (0.1%–0.5%), 70% ethyl alcohol, povidone-iodine (1% iodine), chloroxylenol (0.24%), 50% isopropanol, 0.05% benzalkonium chloride, 1% cresol soap, or hydrogen peroxide (0.5%–7.0%), etc. Just like the WHO recommendations for Ebola virus (RG4) disinfection, the environment with spills of blood or body fluids could be cleaned up with 1:10 dilution of 5.25% household bleach for 10 minutes.

Preprocedural mouth rinse: previous studies have shown that SARS-CoV and MERS-CoV were highly susceptible to povidone mouth rinse [25]. Therefore, preprocedural mouth rinse with 0.2% povidone-iodine might reduce the load of corona viruses in saliva [22,26]. Another alternative would be to use 0.5-1% hydrogen peroxide mouth rinse, as it has non specific virucidal activity against corona viruses [27].	Ather et al.
