Many long-covid symptoms linger even after two years, new study shows

People who endured even mild cases of covid-19 are at heightened risk two years later for lung problems, fatigue, diabetes and certain other health problems typical of long covid, according to a new study that casts fresh light on the virus’s true toll.

The analysis, published Monday in the journal Nature Medicine, is believed to be the first to document the extent to which an array of aftereffects that patients can develop — as part of the sometimes debilitating syndrome known as long covid — linger beyond the initial months or year after they survived a coronavirus infection.

According to the findings, patients who suffered bouts of covid severe enough to put them in the hospital are especially vulnerable to persistent health problems and death two years after they were first infected. But people with mild or moderate cases are not spared from the consequences when compared with those who never had covid, showing an elevated risk of two dozen medical conditions included in the analysis.

The study highlights the burden that continues to confront millions of people in the United States and the nation’s health-care system even though the federal government canceled the coronavirus public health emergency three months ago and the World Health Organization has declared the pandemic no longer a public health emergency of international concern.

“A lot of people think, ‘I got covid, I got over it and I’m fine,’ and it’s a nothingburger for them. But that’s not everything,” said the study’s senior author, Ziyad Al-Aly, a clinical epidemiologist at Washington University School of Medicine in St. Louis. After a couple of years, “maybe you’ve forgotten about the SARS-CoV-2 infection … but covid did not forget about you. It’s still wreaking havoc in your body,” said Al-Aly, chief of research at the Veterans Affairs St. Louis Health Care System.

Fitness: Only 5,000 steps a day needed to stay healthy, study shows

Walking is key to reducing the risk of death, according to a new study

It has long been touted that 10,000 steps a day is the magic number you need to stay fit and healthy – but a new study shows fewer than 5,000 may be enough to see a benefit.

The analysis of more than 226,000 people around the world showed 4,000 was enough to start reducing the risk of dying prematurely of any cause.

Just over 2,300 is enough to benefit the heart and blood vessels.

The more you do, the more health benefits are seen, researchers said.

Every extra 1,000 steps beyond the 4,000 reduced the risk of dying early by 15% up to 20,000 steps.

The team from the Medical University of Lodz in Poland and Johns Hopkins University School of Medicine in the US found the walking benefits applied to all genders and ages, regardless of where they lived.

However, the biggest benefits were seen among the under-60s.

Prof Maciej Banach, from the Lodz university, said that while the number of advanced drugs for treatment was growing, they were not the only answer.

“I believe we should always emphasise that lifestyle changes, including diet and exercise, which was a main hero of our analysis, might be at least as, or even more, effective in reducing cardiovascular risk and prolonging lives,” he said.

Walking to the shops instead of driving, or getting off the bus a couple of stops early could be enough to make a difference

According to World Health Organization data, insufficient physical activity is responsible for 3.2 million deaths each year – the fourth most frequent cause worldwide.

Honey Fine, a personal trainer and instructor for global fitness company Barry’s, emphasises the problems that come from sitting down too much.

“It can slow your metabolism and affect muscle growth and strength, which can cause aches and pains,” she tells the BBC.

“Sitting down for too long can also cause all sorts of back problems, we find this a lot with people with office jobs, that their backs are constantly put in a stressed compressed position which causes a lot more problems later on in life.”

She explains the importance of non-exercise activity thermogenesis – also known as Neat, “which in simple terms is everything we do that uses energy and burns calories”.

“Tasks like standing, carrying shopping, washing the floors, hoovering, pacing whilst walking on the phone – it’s all the little things that make us more active that help us to burn calories more efficiently,” she said.
