The World Health Organization (WHO) has declared a global health emergency over a new coronavirus. The new corona virus (SARS‐CoV‐2) has raised global attention with raising concerns of rapid spread from human‐to‐human. Like severe acute respiratory syndrome (SARS)‐nCoV, 2019‐nCoV can be passed directly from person to person by respiratory droplets, and may also be transmitted through contact and fomites.

The World Health Organization (WHO) has declared a global health emergency over a new coronavirus. The new corona virus (SARS-CoV-2) has raised global attention with raising concerns of rapid spread from human-to-human. Like severe acute respiratory syndrome (SARS)-nCoV, 2019-nCoV can be passed directly from person to person by respiratory droplets, and may also be transmitted through contact and fomites. 1 Currently, there is no vaccine or specific therapeutic option against the new virus. Hygienic hand antisepsis is one of the most important measures in preventing healthcare-and outbreak-associated viral infections. Hence, there is an emergency in identifying efficacious antiviral agents to combat the disease. 2 Appropriate measures to decrease the risk of transmission from infected person to the patients, visitors and health care workers include hand hygiene. Appropriate care is to be considered for higher risk patients with chronic lung disease, diabetes, and renal failure, as well as immunocompromised patients. WHO formulations I and II (two alcohol-based hand rubs) or povidone iodine (PVP-I) are highly effective against the enveloped corona viruses (Table 1) , as well as other antiseptic agents. 3 If alcohol-based hand rubs (gel or foam) or povidone iodine are

The accessibility of the WHO / PVP-I formulations as well as their correct use is therefore likely to be of significant benefit for human health on a global scale, particularly in the developing countries. 3 Repeated hand disinfection must be paired with simple handwashing. This has been shown to be of even increased efficiency compared to disinfection for both enveloped and nonenveloped viruses. 8 Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses UVC radiation to Phenolic -Bacteria.
