Flu forecast 2019: Here’s what to expect from this year’s flu …

cold morning, the leaves are changing, and the kids are back in school, back to share with others -. Including, eventually, flu

Canada’ve seen her this fall, according to the Public Health Agency of Canada. Experts say that we are most likely to see flu season “typical” this year.

Here’s what it means.

Typically, Canadian flu season begins in the fall and peak sometime between late December and early February.

When the Canadian experts want a clue about what our flu season might look like, they often look to the south, said Alyson Kelvin, an assistant professor at Dalhousie University and an expert on the influenza virus Canada Center vaccinology. Specifically, they look at Australia, which is experiencing flu season during our summer (and winter).

“We can kind of look to see what is happening there, and generally there is a trend visible in our next flu season,” he said.

This year, the flu season in Australia started very early, with most cases in the beginning of the season, he said, and while it tapered off, the high number of cases overall.

“It seems like there are large numbers of cases early, early in the season and all the people of course began to worry and panic about it because it means, ‘Oh no it will be a bad year this year and everything something else, ‘ “said Dr. Gerald Evans, chairman of the Division of Infectious Diseases at Queen’s University.

The new data from Australia showed that although the flu season, while unusual, is formed by the unique geography of Australia and the same thing may not happen in other places, he said. “We have not seen any goods in countries other southern hemisphere. So it is not in New Zealand, not in Chile and Argentina and in South Africa, which is the other countries which typically reports the data of their flu season “

If we start our flu season as early as Australia began to them, Dr. Michelle Murti, a public health physician with the Ontario Public Health, said that we would already see a lot of cases. But we did not.

“We kind of see their usual seasonal levels for this time of year,” he said. “We did not enter the season the same way they do. What it means in the end, we do not know. But I think it is by far a better sign for us that we do not put it at a high level that they come in. “

Both Murti and Evans thought that our flu season is likely to begin at the usual time – .. began to pick up in October, with a peak around the end of December

so far, the signs are pointing to the flu season Canada did not become particularly rough this year

see Australia, Kelvin said, while they have a lot of flu cases, relatively few people get very sick from it.

“The good news is that even though they have a higher number of cases reported, that when we actually measure the severity of influenza, which is the number of hospitalizations and deaths, their rates are quite low,” he said

Evans expects normal numbers of infected people (in Canada are approximately 40,000 cases were confirmed on average over the last five years), with a normal number of hospitaliza tions and death.

Perhaps there is one complication though: this year, the dominant flu strain in Australia is of the type H3N2, which often leads to more severe disease, Evans said

“Usually H1N1. slightly milder season slightly as more senior citizens who have immunity to H1N1, “said Murti. “So we typically see cases of H1N1 less in a year than in H3N2.”

The shots typically protect against H1N1 flu strain, H3N2 strain, as well as two types of Influenza B, said Kelvin. Every year, WHO met to decide what should be targeted by the vaccine strain -. Pluck those most likely to spread during the upcoming flu season

“You can think of a vaccine for nearly a multivitamin that has four different components or materials to protect you from four different viruses,” he said. “And what we want to do is really according to what is circulating in the community with our annual influenza formulations.”

JAM: This is the reason why Canadians do not get the flu vaccine this year

Unfortunately, it is difficult to correctly guess the H3N2 strain, said Murti. Often mutate, making the vaccine less effective. It can also mutate in the lab, while drugmaker grown vaccine, so that what ends up in your flu vaccination may no longer quite what’s in the environment, he said.

So if H3N2 is more dominant this year, Evans said, there may be some “mismatch” between what the vaccine protects against and what we encounter.

by saying that, she still thinks you should get a flu shot. “Flu shot is useful for everyone in terms of reducing the opportunity to get influenza, and also if you get it, it should reduce the severity of it by giving some excellent immunity against the virus itself.”

“As soon as the vaccine becomes available, the number one thing to say, that people – especially those at high risk for influenza – should get a flu shot,” said Murti

That includes people over 65, children under five, pregnant women and people with underlying health conditions such as heart disease, respiratory disease, diabetes and obesity.

If you are in one of these high potential -Risk group had more severe reactions flu, he said, you may even want to consider consulting with your doctor before flu season really starts, to find out plan of action should you get sick. This can include such things as having easy access to a prescription for antiviral therapy.

In addition to the flu shot, you also should wash your hands frequently, cough into the elbow or sleeve instead of your hands, and stay home if you’re feeling ill, he said.

If you are sick with respiratory illness and you’re feeling short of breath, fever constantly high, or have a disease that disappears after a few days but then came back hard, Evans said all signs that you should visit a doctor.
