'That said, early signs suggest it doesn't seem to cause more serious illness, but of course, we're still learning more about it,' said Tang.
The earliest sample of Nimbus was taken in January, said WHO.
How are Canadians being affected by the Nimbus strain?
In Canada, the federal government has been keeping track of COVID variants detected nationwide.
Nimbus was detected in Canada in March, but it only accounted for a very low percentage of COVID strains in the country, at just 0.2 per cent . By the end of May, Nimbus made up roughly 20 per cent of all identified COVID cases. Using earlier trends to estimate the current situation, the government is predicting how variants will spread or diminish. This method is called nowcasting.
For the week of June 1, the nowcasted estimates of Nimbus in Canada are predicted to be around 42 per cent. The nowcasted estimates for the week of June 15 jump to 53 per cent, meaning it would make up more than half of the cases in Canada if the prediction is accurate.
Other than Canada, Nimbus has been detected around the world, with cases reported in India, Thailand, Hong Kong, Singapore and the United States, according to the World Health Network. It has also made its way to Australia and the United Kingdom.

'Nothing threatening about it': U of C study explores how robots could address social isolation in seniors
Article content Loneliness and social isolation are growing challenges for older adults living in care facilities. But a recent study by a University of Calgary student suggests that robots might be able to fill the gaps where existing programs fall short. Article content Fahimeh Mehrabi, a PhD student in psychology at the U of C, presented a research paper earlier this month at the Congress of the Humanities and Social Sciences in Toronto, titled Wired for Companionship: A Meta-Analysis on Social Robots Filling the Void of Loneliness in Later Life. Article content Article content Article content Article content Her research compiled available quantitative studies that measured loneliness before and after using robots. When she combined and reanalyzed the data, the results were promising. Article content 'Our findings showed that all types of social robots, whether simple or more advanced, can help. As long as they are designed to engage and interact, they are effective,' she said. Article content The idea isn't as far-fetched as it sounds — social robots have been tested in elder care for more than a decade in countries such as Japan and Turkey. Article content Article content Models range from human or pet-like robots that offer comfort through touch and movement, to voice-activated AI companions that can engage in conversations. Often, they offer some combination of both. Article content Unison, the not-for-profit organization that runs the Kerby Centre in Calgary, is all too familiar with the prevalence of social loneliness and isolation among its clients. Article content 'There was a recent study that found prolonged isolation was as bad as smoking 15 cigarettes a day,' said Larry Mathieson, president and CEO of Unison. Article content Unison is tackling senior isolation and loneliness through a wide range of traditional programs at the Kerby and Veiner Centres. These include hundreds of fitness, music and social classes available in person or online. Article content During the COVID-19 pandemic, Unison's online classes helped seniors learn new tech skills and stay socially active. Online classes under its Active Aging department stayed in place post-pandemic due to their accessibility and positive effects.

Extreme heat can turn dangerous fast. Who is most vulnerable?
Doctors and health-care experts are warning Canadians to not only look after themselves but also check on others who could be vulnerable as large parts of central Canada face a sweltering heat wave. Global News chief meteorologist Anthony Farnell says a large heat ridge or dome will build over the Ohio Valley in the U.S. and expand into southeastern Canada by the end of the weekend. Temperatures are expected to reach the low to mid-30s C and the humidex could make that feel much higher, with humidex readings potentially into the mid-40s. When heat hits those levels, the body has to work harder to keep itself cool. 'The hypothalamus acts as the thermostat and sends signals to the heart to start beating faster, sends signals to our body to breathe a little faster and that helps the blood flow to the extremities so that we can dissipate heat through radiant heat loss,' said Dr. Samantha Green, a family physician at Unity Health Toronto with expertise in climate change and health. Story continues below advertisement 'It also sends signals so that we can cool down through evaporative cooling through sweating.' What does extreme heat do to your body? Prolonged exposure to heat can impact the human body in a variety of ways. One of the most common is heat exhaustion, which can lead to heat stroke. Heat exhaustion is characterized by headache, dizziness, extreme thirst, heavy sweating, muscle cramps and nausea and vomiting, according to Health Canada, and people are advised to immediately move to a cool place and drink water if experiencing these symptoms. If left untreated, that exhaustion can become heat stroke, which is defined by Johns Hopkins Medicine as the body being overwhelmed by excessive heat. Those suffering from heat stroke often have an internal temperature of 40 C or higher, warm, dry skin, confusion and nausea, and it can lead to worse conditions, including seizures, coma and even death. Story continues below advertisement While people will keep an eye on the temperature, studies show that people should also be aware of the 'wet bulb' temperature — when both humidity and air temperatures are high, it can be harder to shed heat and keep yourself cool. A 2010 study found that a wet-bulb temperature of 35 C that lasts longer than six hours could cause serious health impacts or even death.

Story continues below advertisement 'If you don't feel well from the heat, seek medical attention or call 911. Don't be afraid to ask for help,' said Caroline Metz, managing director of climate resilience and health at the Intact Centre on Climate Adaptation at the University of Waterloo. Vulnerable populations, such as youth and older adults or those with chronic conditions, may find it more difficult to beat the heat. Who's most at risk? Nemours Children's Health in the U.S. notes that children's bodies are still developing and may sweat at a lower rate than adults and start sweating at a higher temperature, putting them more at risk of heat-related illness. Older adults face higher risks as they may have trouble accessing cool spaces due to mobility or transportation challenges, and those living alone may be more vulnerable as a result, according to B.C. Interior Health. Story continues below advertisement Older adults, as well as other Canadians, may also have chronic underlying health conditions or be taking medication that could interfere with the body's ability to stay cool. The U.S. Centers for Disease Control and Prevention notes that those with these conditions may be less likely to respond to changes in temperature, and that those with heart disease, mental illness and obesity have a higher risk of heat-related illness. 4:08 Summer heat can be dangerous for seniors 'It's also why people with chronic health conditions are more at risk of developing heat exhaustion, heat stroke, where the body's natural cooling mechanisms break down and the core body temperature exceeds 40 degrees,' Green said. 'That's where we end up with massive inflammation and failure of organs in the body.' People taking chronic medications can also be affected. Green said beta blockers, for example, prevent the heart from beating faster in response to heat and keep the body from naturally being able to cool down. Story continues below advertisement It's not just health conditions or age that can pose vulnerabilities, however. 'Anybody who's working outside or people experiencing homelessness, they're more exposed to heat and that's a group or a population that's more at risk,' Metz said. How to protect yourself and others Metz notes that during heat waves, it's important for people to watch out for others and check in on neighbours because those living alone or socially isolated can also be vulnerable to heat. A B.C. coroner's report following the 2023 heat dome noted that 98 per cent of the 619 deaths identified as being related to heat occurred indoors, with 56 per cent of those who died living alone. 'Social cohesion or social connectedness has been shown to be a very important factor for resilience and for health during heat waves,' Metz said. Story continues below advertisement 'In fact, in some cultures where there are multi-generational families living together, it's just very natural for people to care about others … so they don't often experience the same kind of situation that we might have here in North America, where we have one generation living in a household. 'The ability to reach out, call someone, or stop by has been shown to greatly support health and well-being for people who are isolated.' She added that older adults and those living alone should reach out to other people to let them know they're on their own and are open to having someone check on them during periods of extreme weather. As a heat wave enters Ontario later this weekend, Metz said people should stay in the coolest part of their home if possible or go to a community cooling centre, wear lighter-coloured clothing if you have to go out, keep your doors and windows closed during the hottest parts of the day, and turn off items that may produce extra heat in your home. 'If you need to be out, you want to do that during the parts of the day that are the coolest,' she suggested, noting this means early mornings and late evenings.
