Vira Block is a doctor-approved, hospital level liquid hand antiseptic. This ready-to-use product offers an easy and effective way to disinfect hands and reduce the spread of germs that can cause disease and infection.

Clinically proven, Vira Block has 15 times more germ-killing effectiveness that typical sanitizer gels. *(2002)

Recent laboratory studies have found alcohol-based hand rinses (liquids) reduce bacterial counts on the hands of volunteers to a greater degree than hand gels. (2,3)

In vivo efficacy data has shown our formula to be effective against a wide range of pathogens, bactericidal (ecoli, strep, stapha, MRSA, VRE). Bacterial testing description, EU 1500, FDA tentative final monogram #333470,1994

In Vitro Viral Studies, Activity

Additional international efficacy data further confirms product spectrum of effectiveness against pathogens including hepatitis A-C, HIV, influenza B (Avian), rotavirus, and adenovirus.

In general many alcohol-based hand rubs are likely to be effective against enveloped viruses such as herpes simplex, human immunodeficiency, hepatitis B, and respiratory syncytial virus (1,5).

Non-enveloped viruses such as rhinovirses, adenovirus and rotavirus tend to be somewhat more resistant to alcohols. However, alcohols have been shown in in-vivo studies to significantly reduce the titer of such viruses recovered from artificially contaminated fingers (6,7). Additionally other non-enveloped viruses including Hepatitis A virus and enteroviruses are the most resistant to disinfectants and antiseptic agents. Alcohol-based preparations with high alcohol content EG 75-95% ethanol are more likely to be effective against hepatitis A virus and enteroviruses (1,8,9).

Vira Block Antiseptic Hand Wash is available in both a 4 oz. spray and gel. Vira Block reduces the germs that cause illness and disease and helps reduce the risk of infection and cross-contamination.
