COVID-19 Update
World Health Organization Directives on Preventing COVID-19 Transmission
- Steve Rutchinski -
As Canada begins to emerge from strict lockdown
measures and enters a phase of loosening the restrictions which served
to flatten (though not yet reverse) the infection curve, international
experience and the advice of the World Health Organization (WHO) hold
importance for us going forward.
In his July 13 coronavirus situation briefing, the
Director General of WHO characterized, in broad strokes, four stages of
the pandemic and said what "we're seeing is countries that overcame the
first peak of the outbreak, but having eased restrictions, are now
struggling with new peaks and accelerating cases. In several countries
across the world, we are now seeing dangerous increases in cases, and
hospital wards filling up again. It would appear that many countries
are losing gains made as proven measures to reduce risk are not
implemented or followed."
WHO has set out recommendations, including
measures to keep COVID 19 transmission in check. Its recommendations
contained in its Scientific Brief entitled "Transmission of SARS-CoV-2:
implications for infection prevention precautions" dated July 9 are
based on a detailed review of dozens of recent scientific studies of
how COVID-19 infection is transmitted.
"Based on what we currently know, transmission of
COVID-19 is primarily occurring from people when they have symptoms,
and can also occur just before they develop symptoms, when they are in
close proximity to others for prolonged periods of time. While someone
who never develops symptoms can also pass the virus to others, it is
still not clear to what extent this occurs and more research is needed
in this area."[1]
The July 9 report outlines transmission factors in
detail and from the scientific evidence to date reached definite
conclusions which resulted in the formation of the following
recommendations on how to keep COVID 19 transmission in check:
- Identify
suspect cases as quickly as possible, test, and isolate all cases
(infected people) in appropriate facilities;
- Identify and
quarantine all close contacts of infected people and test those who
develop symptoms so that they can be isolated if they are infected and
require care;
- Use fabric
masks in specific situations, for example, in public places where there
is community transmission and where other prevention measures, such as
physical distancing, are not possible;
- Use of contact
and droplet precautions by health workers caring for suspected and
confirmed COVID-19 patients, and use by health care workers of airborne
precautions when aerosol generating procedures are performed;
- Continuous use
of a medical mask by health workers and caregivers working in all
clinical areas, during all routine activities throughout the entire
shift;
- At all times,
practice frequent hand hygiene, physical distancing from others when
possible, and respiratory etiquette; avoid crowded places,
close-contact settings and confined and enclosed spaces with poor
ventilation; wear fabric masks when in closed, overcrowded spaces to
protect others; and ensure good environmental ventilation in all closed
settings and appropriate environmental cleaning and disinfection.[2]
On July 13 the Director General concluded his
briefing with these words: "I want to be straight with you: there will
be no return to the "old normal" for the foreseeable future. But there
is a roadmap to a situation where we can control the disease and get on
with our lives. But this is going to require three things:
"First, a focus on reducing mortality and
suppressing transmission.
"Second, an empowered, engaged community that
takes individual behaviour measures in the interest of each other.
"And third, we need strong government leadership
and coordination of comprehensive strategies that are communicated
clearly and consistently.
"It can be done. It must be done. I have said it
before and I will keep saying it."
Working people do not have control over what
measures are taken by governing authorities but they are speaking out
-- front line health care workers, transit workers, teachers and
education workers, miners and industrial workers, retail, hospitality
and child care workers, migrant workers in farm and meat packing
industries and many more.
TML Weekly and
Workers' Forum report on the experiences of workers
who have organized when employers refused to do it, which now includes
contact tracing; of mine workers in Quebec whose union played
a key role in determining health and safety measures for return to work
underground; of transit workers speaking out for mandatory use of masks
on mass transit; of teachers speaking out for government to implement
safe working conditions for reopening of schools; of migrant workers
demanding status as key to achieving safe working and living
conditions. It is the working people taking up social responsibility
and advocating for constructive measures they know will protect
themselves and society at large that is the decisive element as we go
forward.
