Toronto-After the federal COVID-19 model showed that the decline could lead to another surge in COVID-19 cases and the rapid spread of Delta variants, doctors said that the best way to avoid the fourth wave is to vaccinate, test, track, and isolate.

The model released on Friday by Canada’s Chief Public Health Officer, Dr. Theresa Tam, shows that due to the more contagious Delta variant, cases have started to increase, but there is still time to flatten the curve.

“There is no summer vacation for the second and first doses because we don’t have that leeway,” Dr. Lisa Barrett told CTV News on Saturday.

She added that people who have the first or second delayed injection need to work hard to get it as quickly as possible.

She said: “During respiratory virus seasons like autumn, before we get into all these return to school and other situations, we have to move on.”

Although breakthrough cases have occurred in the vaccinated population, they are still rare, and the vaccine is still the best defense against COVID-19.

Barrett said: “In large part because these vaccines are great, they are the cornerstone of our prevention toolbox and control.” “The limitation of the virus really, really depends on people getting two doses of this vaccine.”

Canadians can also take other measures to continue to protect themselves, whether vaccinated or not, which is no different from the measures urged since the beginning of the pandemic: masks and testing.

Barrett said: “In addition to vaccines, there are some simple tools, such as masking and testing, which can reduce the risk of this disease for unvaccinated people.”

Although the model shows that there may be a fourth wave in the fall, an infectious disease expert said that the quality of the model depends on the variables put in it, but there is still a possibility of another surge.

“We may have a fourth wave. I guess this may be the fourth wave of calm, because unlike the previous waves, we did vaccinate people,” Ronald, former director general of the Emergency Preparedness and Response Center Dr. St. John told CTV News on Saturday.

Although provinces have begun to relax restrictions, or in some cases completely lift restrictions, a doctor said that people who have not been vaccinated will be hit hardest by the fourth wave of the epidemic.

“The fourth wave will definitely affect those who have not been vaccinated, but I think what we really need to start to pay attention to is who are these unvaccinated people?” Veronica, Director of Northern Medical Services, University of Saskatchewan Dr. McKinney told CTV News on Saturday.

She said that people who have not been vaccinated need to be identified so that doctors and experts can cooperate with them so that they can be assured of being vaccinated to protect themselves and others.

“The way it is portrayed is that it is a personal choice and people are just resisting, but I really believe it is time to see what causes this in the system?” she said.

McKinney added that policies need to change to encourage people to get vaccinated, but they also need to take time off when they are sick.

“We need to look at the policies that make things difficult, those who don’t have sick leave, those who don’t want to be tested because they don’t want to get off work but don’t necessarily believe what is happening,” she added.

McKinney said that even with the increasing number of gunmen, provinces such as Saskatchewan and Alberta have cancelled necessary public health measures to prevent the fourth wave of epidemics.

“Part of the challenge our community is facing now is that there are no more public health orders that can be used to help people stay quarantined when they need it. Testing all those is very helpful, but no longer exists. [Saskatchewan],” she says.
