To help stop the spread of coronavirus, health officials recommend avoiding large gatherings and maintaining a distance of 1-2 meters from other people. Social distancing places no such location constraints; rather, it is a behavioral practice to lower the risk in most circumstances.

A number of companies asked their employees to work from home, with some of them having carried out remote work policies. This unexpected experiment has been so well-received that employers are considering adopting it as a more fixed measure. For some digital-based sectors, working from home has instead been surprisingly effective.

Everybody has been trying to recover from the impact of COVID-19 in 2020 by remote working, online education, social distancing and more. Countries suffering from the coronavirus are trying to recover. Many of them have promoted tax and fee reductions, improved the business environment, and inspired the enthusiasm of market players.

The World Health Organization declared in March that the spread of COVID-19 had become a pandemic. More than 200 countries and territories around the world have reported confirmed cases of the coronavirus. Global health authorities and vaccine developers are currently partnering to support the technology needed to produce vaccines(疫苗).

It was a year when the whole world had to collaborate and work together in unity to overcome challenges faced by all of mankind. Some of these major events include severe natural disasters, economic recession（衰退）and COVID-19. These events have brought the world closer, allowing billions of people across the world to experience the true power of a united mankind.

Obesity should be defined by a person's health - not just their weight, says a new Canadian clinical guideline. It also advises doctors to go beyond simply recommending diet and exercise. Instead, they should focus on the root causes of weight gain and take a holistic(整体的)approach to health.

Ximena Ramos-Salas, the director of research and policy at Obesity Canada and one of the guideline's authors, said research shows many doctors discriminate(歧视) against obese patients, and that can lead to worse health outcomes regardless of their weight. "Weight bias(偏见)is not just about believing the wrong thing about obesity," she told the BBC. "Weight bias actually has an effect on the behaviour of healthcare doctors."

Although the latest advice still recommends using diagnostic(诊断的)criteria like the body mass index (BMI) and waist circumference, it admits their clinical limitations and says doctors should focus more on how weight affects a person's health. Small reductions in weight, of about 3-5%, can lead to health improvements and an obese person's "best weight" might not be their "ideal weight" according to BMI, the guideline says.

It emphasizes that obesity is a complex, chronic condition that needs lifelong management. "For a long time we've associated obesity as a lifestyle behaviour. It's been a lot of shame and blame before," Ms Ramos-Salas says. "People living with obesity need support like people living with any other chronic diseases." But instead of simply advising patients to "eat less, move more", the guideline encourages doctors to provide supports along the lines of psychological therapy(治疗), medication and bariatric surgery like gastric-bypass surgery(胃分流手术).

The guideline doesn't completely give up standard weight-loss advice. "All individuals, regardless of body size or composition, would benefit from adopting a healthy, well-balanced eating pattern and engaging in regular physical activity," it says.
