Medical concerns
Globally, an estimated 170 million
people (3% of the global population)
are infected with the hepatitis C
virus (HCV). According to the latest
assessments, over 40 million people
are currently virally infected with
HIV, and 350 million suffering
from chronic HBV infection with
hepatitis B.
Obviously, throughout their daily
practice healthcare professionals
are in contact with patients who are
potentially virusccontaminated. Of
all the viruses, hepatitis B and C,
along with AIDS, cause the greatest
concern and, as a result, healthcare
professionals want to be certain they
are using the best possible materials to prevent viral contamination.
More and more, they question glove
manufacturers about the level of
protection provided by their products against bloodcborne viruses
because viral penetration may,
potentially, occur through any glove
imperfections, such as pinholes.
Insufficient regulation
In Europe, there is no regulation
regarding viral penetration through
medical gloves. The EN-455 Part I
standard (‘Requirements and testing for freedom from holes’) merely
requires the statistical testing of
glove impermeability (AQL measurement). This testing is carried
out through a static methodology
involving water contact.
Europe apply the American standard ASTM F1671-07, which uses
a standard methodology to test the
resistance of protective clothing
materials against penetration by
bloodcborne pathogens and which
utilises the Phi-X174 bacteriophage
penetration as a test system. This
testing methodology has its own
limitations, as the standard itself
describes: “…this test method does
not simulate all the physical stress
and pressures that might be exerted
on protective clothing materials
during use” and “The integrity of
the protective barrier may also be
compromised during use by such
effects as flexing and abrasion.”
Because of their commitment to
improving safety for the healthcare
practitioners, Ansell has decided to
develop the AVPP programme.
