The Brazilian virus is a variant of the CCP virus that is more contagious and more likely to attack young, healthy people.
As of Tuesday (April 6), the total number of confirmed cases of the Brazilian (P.1.) variant of the CCP virus (COVID-19, Neocoronavirus) in Canada was 1,000, almost three times the number of confirmed cases in the United States (356). As a percentage of the population, Canada has the equivalent of 26 confirmed cases per million people, more than 20 times the number of confirmed cases per million people in the United States.
Brazilian variant of the virus more likely to attack young, healthy people
As of April 6, the number of confirmed cases in Canada on a single day was nearly 180 per million people, compared to 196 in the United States. Experts warn that at this rate, the number of confirmed cases in Canada on a single day could exceed that of the United States in the coming days. On both the east and west coasts of the country, the Brazilian variant of the virus is causing increasing panic because the Brazilian cases are more contagious and more likely to attack younger, healthier people than the primary virus.
There are now more than 15,000 confirmed cases of the variant virus across Canada, far exceeding the 9,000 cases last month. Of these, the B.1.1.7 UK variant has a total of 14,790 cases, far exceeding the number of confirmed cases of the Brazilian variant. The problem is that the Brazilian variant of the virus is spreading rapidly in the country, especially in British Columbia, where the situation is most critical.
Federal and provincial chief health officers last week held a special discussion on the Brazilian variant of the virus, to discuss strengthening cooperation on prevention. Health officials said the variant virus is spreading rapidly, and people still need to control social interactions and must wear masks when they go out.
Spread by province
As of Tuesday, there were 1,000 confirmed cases of the Brazilian variant of the virus in Canada, including 877 in British Columbia, followed by 106 in Ontario, 15 in Asia and two in Quebec, and none in the rest of the country at this time.
The problem is that the spread of the variant virus may be more severe in the provinces. This is because the variant virus from screening to the final diagnosis needs to wait a few days before the final confirmation. For example, nearly 2,300 cases of variant virus have been confirmed in Ontario, but more than 27,000 cases have been sampled and are still waiting for final confirmation.
The BC CDC internal documents obtained by the Canadian media show that the province as of last month 27 presumed cases of variant virus accounted for at least 40% of all positive confirmed cases, which is twice the number of confirmed cases estimated by the provincial health officer last month 25. These 2 figures do not take into account the rapid rise in cases during the Easter long weekend when the number of confirmed cases of Brazilian variant virus almost doubled.
Global transmission and contagiousness
The first case of the Brazilian variant was detected in Manaus, the 7th most populous city in Brazil, in December last year, followed by the introduction of the virus into Japan by Brazilian tourists and into the United States in January this year, and the first case of the Brazilian variant was reported in Canada in February by a Toronto resident returning from a trip to Brazil (who was hospitalized after being diagnosed with a serious illness).
To date, only 356 cases of the Brazilian variant have been confirmed in the United States, far fewer than the 1,000 cases in Canada. The Brazilian variant of the virus has been found in more than a dozen countries in the Americas and has become the biggest epidemic prevention concern.
Researchers have found that the Brazilian variant of the virus is nearly 2.5 times more contagious than the basic rate of transmission, but some studies have concluded that the contagion is not so high. The problem is, Brazil since the discovery of the variant virus, has become the epicenter of the virus pandemic, a single day mortality rate accounted for 1/4 of the global infected, the total infected death population of nearly 337,000, second only to the United States of 555,000.
More contagious and lethal
The Brazilian variant of the virus is worrisome because after mutation, the virus is more contagious and more resistant to vaccines and antibodies produced in the infected population, and people who have been vaccinated and previously infected are still likely to be infected.
Brazilian experts warn that young people are not only more likely to be infected, but also more likely to die. BC zoology professor Ms. Otto (Sarah Otto) revealed that the Brazilian variant of the virus infection mortality rate increased by 10% to 80%.
Some studies have shown that Pfizer and Moderna vaccines have the potential to neutralize the Brazilian variant of the virus. The data suggest that the neutralization of the Brazilian virus by naturally occurring antibodies and vaccine-generated antibodies in previously infected and recovered populations is low and that resistance to the Brazilian virus may not be as great as previously feared. That said, there is still a lack of sufficient data to provide support. Canada’s chief health officer has previously warned that laboratory data show the vaccine has little effect on the Brazilian variant of the virus.
Experts caution that preventing infection with the Brazilian variant of the virus is the same as previous prevention approaches, such as maintaining social distance, washing hands regularly, avoiding contact with dense crowds and places with poor air circulation, avoiding indoor gatherings, wearing masks when you go out, staying home as much as possible when you are sick to reduce the probability of transmission outside, and following the latest prevention recommendations of provincial health officials.
