Health officials say current public health measures around masking and distancing will protect Albertans against the new variants of the novel coronavirus, but there are some extra precautions that can be taken.
Alberta Health reported Monday that there were 20 cases of the UK variant and five cases of the South African variant in the province; while most were travel-related, there is one case that appears to be the result of community transmission.
Infectious disease epidemiologist Zahid Butt of the University of Waterloo said people will need to be more vigilant now about following public health guidelines.
“We need to be more careful about distancing now. We need to be more careful about wearing masks. We should be more careful about hand sanitization and other measures,” Butt said.
The variants can transmit faster between people because of changes to the spike proteins on the virus’s surface, which allows it to enter cells more easily. Higher transmission of the virus means there is the potential for more cases and, with that, the possibility there could be more hospitalizations.
Should people wear two masks?
While some Americans are wearing two masks, Butt said he wouldn’t recommend it.
“Currently they just recommend one mask because…it has a better fit, it’s a more comfortable fit,” Butt said, adding he recommends wearing a mask everywhere, even outdoors.
Butt also said that three layers in a mask will protect a person more than a mask with just one layer.
“Additionally if you have a mask which you can actually put in a filter, in addition to your three layers, that will protect you better,” he said.
Infectious disease physician Dr. Stephane Smith agrees, saying she doesn’t think there’s any evidence to suggest wearing two masks is more protective than wearing one.
Smith said N95 can filter small air particles but those are recommended for those working in hospital settings.
“For most people in everyday settings, the surgical mask or its equivalent is effective in preventing transmission from larger droplets,” she said.
Smith said wearing masks indoors is very important and wearing masks outdoors is also important if you are going to be in close contact with someone, but she balks at wearing a mask at all times when outdoors.
“If you’re just out for a walk in your neighbourhood and you don’t actually interact with anyone then you probably don’t need to wear a mask at all,” she said.
Should people distance more than two metres?
Albertans have been told to distance two metres from people outside of their household, but Butt said people can take extra precautions and distance more than two metres to be safe.
Should people cut down the time they spend in indoor spaces?
Smith said, at this point, it isn’t clear how well established the new variants are in Alberta but she recommends curbing interactions.
“If you need to go to the grocery store, go to the grocery store but limiting the amount of time you spend there is still the best suggestion,” she said.
Butt suggests only going out for essential tasks and he also recommends reducing the time spent in closed settings.
What about travel internationally, domestically and within Alberta?
Butt said people should avoid travelling right now, saying this is one way the variant can spread.
“No travelling across provinces and also, if you’re living in an area that’s designated a high-risk area, don’t travel from your high-risk area to a low-risk area,” he said.
Smith said international travel right now is a “bad idea” and that the province should monitor what is happening in other provinces.
“If it does appear there are areas of the country that have widespread transmission of the new variant then I think we would have to look at some restrictions of people coming from that particular province,” she said.
“There have been outbreaks in Ontario related to the new variant. I think this data is emerging. I think we’ll have to keep a close eye on the information that we get from these other provinces to determine what we should be doing about restrictions within Alberta.”
As for travel within Alberta, Smith said there is an increased risk any time you travel because there are more interactions with people that you wouldn’t normally interact with.
Smith suggests curtailing travel within the province unless it is essential.
