Contact transmission of severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) can occur when contaminated hands touch the mucosa of the
mouth, nose, or eyes. Contaminated hands also facilitate indirect
contact transmission of the virus from one fomite surface to another.
Consequently, hand hygiene is important to prevent the spread of
SARS-CoV-2. However, changing plastic gloves or sanitizing hands every
time one touches possibly contaminated fomites will need to be
frequently performed and is practically impossible. The Japanese
Ministry of Economy, Trade and Industry recently reported that
SARS-CoV-2 was deactivated by several diluted surfactants1. Wearing cloth gloves wet with a diluted detergent
will prevent infection because the virus gets deactivated within a short
period of time on these gloves. The virus gets deactivated within a
short period of time on these gloves. Unlike ethanol, detergents are not
volatile. Thus, gloves can remain wet and effective for long periods of
time. Although the thin diluted detergent could remain on the touched
sites, it can be rinsed under running water or wiped afterwards, if
necessary. In case of contamination, the detergent remaining on the
fomites may also deactivate the virus. To avoid skin contact with the
detergent, a plastic glove can be worn underneath the wet cloth glove.
This method may be especially effective for healthcare workers who deal
with COVID-19 patients or people in the city who handle fomites that
many people touch. Additionally, wearing gloves wet with diluted
detergent may prevent the user from touching his face, which would
further prevent contact transmission.
