Social Distancing



Together, we can slow the spread of COVID-19 by making a conscious effort to keep a physical distance between each other. Social distancing is proven to be one of the most effective ways to reduce the spread of illness during an outbreak. With patience and cooperation, we can all do our part.

What does Social Distancing mean?
This means making changes in your everyday routines in order to minimize close contact with others, including:

  • avoiding crowded places and non-essential gatherings
  • avoiding common greetings, such as handshakes
  • limiting contact with people at higher risk (e.g. older adults and those in poor health)
  • keeping a distance of at least 2 arms lengths (approximately 2 metres) from others, as much as possible
Here’s how you can practice social distancing:
  • greet with a wave instead of a handshake, a kiss or a hug
  • stay home as much as possible, including for meals and entertainment
  • shop or take public transportation during off-peak hours
  • conduct virtual meetings
  • host virtual playdates for your kids
  • use technology to keep in touch with friends and family
If possible,

  • use food delivery services or online shopping
  • exercise at home or outside
  • work from home
Remember to:
  • wash your hands often for at least 20 seconds and avoid touching your face
  • cough or sneeze into the bend of your arm
  • avoid touching surfaces people touch often
If you’re concerned you may have COVID-19:
  • separate yourself from others as soon as you have symptoms
  • if you are outside the home when a symptom develops, go home immediately and avoid taking public transit
  • stay home and follow the advice of your Public Health Authority, who may recommend self-isolation
  • call ahead to a health care provider if you are ill and seeking medical attention

VIABILITY OF SARS-COV2 ON VARIOUS SURFACES:
SARS-CoV-2 was more stable on plastic and stainless steel than on copper and cardboard, and viable virus was detected up to 72 hours after application to these surfaces , although the virus titer was greatly reduced (from 103.7 to 100.6 TCID50 per milliliter of medium after 72 hours on plastic and from 103.7 to 100.6 TCID50 per milliliter after 48 hours on stainless steel). The stability kinetics of SARS-CoV-1 were similar (from 103.4 to 100.7 TCID50 per milliliter after 72 hours on plastic and from 103.6 to 100.6 TCID50 per milliliter after 48 hours on stainless steel). On copper, no viable SARS-CoV-2 was measured after 4 hours and no viable SARS-CoV-1 was measured after 8 hours. On cardboard, no viable SARS-CoV-2 was measured after 24 hours and no viable SARS-CoV-1 was measured after 8 hours.

Both viruses had an exponential decay in virus titer across all experimental conditions, as indicated by a linear decrease in the log10TCID50 per liter of air or milliliter of medium over time . The half-lives of SARS-CoV-2 and SARS-CoV-1 were similar in aerosols, with median estimates of approximately 1.1 to 1.2 hours and 95% credible intervals of 0.64 to 2.64 for SARS-CoV-2 and 0.78 to 2.43 for SARS-CoV-1 . The half-lives of the two viruses were also similar on copper. On cardboard, the half-life of SARS-CoV-2 was longer than that of SARS-CoV-1. The longest viability of both viruses was on stainless steel and plastic; the estimated median half-life of SARS-CoV-2 was approximately 5.6 hours on stainless steel and 6.8 hours on plastic . Estimated differences in the half-lives of the two viruses were small except for those on cardboard . Individual replicate data were noticeably “noisier” (i.e., there was more variation in the experiment, resulting in a larger standard error) for cardboard than for other surfaces , so we advise caution in interpreting this result.

We found that the stability of SARS-CoV-2 was similar to that of SARS-CoV-1 under the experimental circumstances tested. This indicates that differences in the epidemiologic characteristics of these viruses probably arise from other factors, including high viral loads in the upper respiratory tract and the potential for persons infected with SARS-CoV-2 to shed and transmit the virus while asymptomatic. results indicate that aerosol and fomite transmission of SARS-CoV-2 is plausible, since the virus can remain viable and infectious in aerosols for hours and on surfaces up to days (depending on the inoculum shed). These findings echo those with SARS-CoV-1, in which these forms of transmission were associated with nosocomial spread and super-spreading events, an they provide information for pandemic mitigation efforts.
