Concerns as mutated HIV strain in Canada turns into AIDS much faster than usual



A mutated strain of Human Immuno-deficiency Virus (HIV) spotted in Canada is driving sufferers to develop Acquired Immune Deficiency Syndrome (AIDS) quicker than usual, a study reveals.

The strain is circulating in Saskatchewan, where 80 percent of people diagnosed with the illness are Indigenous.

Doctors started reporting alarmingly rapid declines among patients in 2016, when the rate of HIV infections rocketed to 10 times the rate of other regions.


Now, a new study carried out by Simon Fraser University in Vancouver warns there is concrete evidence that this community is the birthplace of a particularly aggressive strain, which is developing faster than modern medicine can keep up with.

They believe the virus has likely adapted to an immune profile specific to the Indigenous community.

“Instead of it taking years, sometimes it just takes a month or a year … and it’s much more aggressive than we would otherwise see,” Dr Alex Wong, an infectious disease physician with the Saskatchewan Health Authority, told The Canadian Press.

Researchers at the university’s BC Centre for Excellence in HIV/AIDS compared 2,300 samples of Saskatchewan strains to other ones obtained across Canada and the United States.

Unequivocally, they found higher levels of mutations that are resistant to the body’s immune responses in the Saskatchewan strains than in the others.


Up to 98 percent of the Saskatchewan strains had an immune-resistant component.

But 80 percent of them had a particularly dangerous mutation that appeared to accelerate illness.

This mutation was also present in the United States (US) and other parts of Canada, but in just 25 percent of the samples.

“Physicians were saying there’s something going on here that isn’t right — people are getting sick very, very fast,” lead author Zabrina Brumme, associate professor of health sciences at Simon Fraser, told the Canadian Press.

“It’s almost as if the virus is nastier.”

HIV is a virus that damages the cells in the immune system and weakens the ability to fight infections and disease.

Without treatment, HIV can turn into AIDS (acquired immune deficiency syndrome), which is a syndrome (or, a set of symptoms) not a virus.

In layman’s terms, AIDS has been referred to as ‘late-stage HIV’.

A person has AIDS when their immune system is too weak to fight off infections. AIDS cannot be transmitted from one person to another; HIV can.

Those diagnosed with HIV need to be on medication for life to prevent it turning into AIDS, which is often fatal.

A decade ago, people who were HIV positive were given a shorter life expectancy because the medication, suppressing the immune system, made patients highly vulnerable to fatal infections.
