Are you tired of hearing about the COVID Virus?
Well we have a change, a new name, the virus that causes the
Covid disease in now appropriately named SARS-COV-2. This clarifies the nature of the virus. It is
a corona virus in the SARS class that infect humans, one of now seven that we
know presently exist. A lot more
infectious than SARS and has more far reaching complications.
Last week we looked at cleaning our spectacles to help
prevent the spread. In my May 1 blog " Contact Lenses During COVID-19
" we
looked at contact lens wear and I would like to go back to this topic in light
of new findings.
The virus has spikes that bind to a receptor on the ACE2
molecule, which are predominant on the cell membranes of the cells of the
lungs, heart, kidneys and intestines.
These receptors are also on the eye and its structures: cornea,
conjunctiva, and sclera. This allows
entry of the virus into the eye, hence the hand washing and contact lens cleaning. Samples of tears from carriers of the virus
are also containing SARS-COV-2.
You can
refer to the following informative article: " COVID-19 found to be spread through eyes and is 100 times more infectious than SARS
"
In light of this knowledge, we definitely need to thoroughly
wash our hands before handling our contact lenses and touching our eyes, but we
also need to be diligent with washing our hands after inserting contact lenses
and touching our eyes, also.
For more information on SARS-COV-2, or COVID-19, please refer to the Canadian Government's COVID-19 Resource Page
. Additionally you can refer to the WHO's (World Health Organization) COVID-19 Resource Page
, and the CDC's COVID-19 Resource Page
.
Until next week, and keep safe,
