When Covid-19<\/a> hit, asthmatics were warned to be extra careful. Since the virus typically damages the lungs and causes breathing problems, these patients were thought to be particularly vulnerable.<\/p>\n

But research has found that during the pandemic, just 14 per cent of people hospitalised with Covid in the UK had asthma.<\/p>\n

What\u2019s more, these patients were more likely to survive than others if they were infected by the virus.<\/p>\n

And now it\u2019s been found that over the past 18 months, the number of asthmatics suffering an attack severe enough to need a visit from their GP was lower than in the previous four years.<\/p>\n

Research has found that during the pandemic, just 14 per cent of people hospitalised with Covid in the UK had asthma<\/p>\n

\u2018There has been a significant reduction in attendance to primary care for exacerbations [attacks] during the pandemic,\u2019 says the study\u2019s lead author, Dr Syed Shah, a chancellor\u2019s fellow at the University of Edinburgh\u2019s asthma research centre.<\/p>\n

Dr Shah and his team analysed the medical records of more than 100,000 asthma patients and found a 20 per cent drop in the number of GP visits for asthma attacks.<\/p>\n

However, the number of attacks severe enough to need hospital treatment didn\u2019t change.<\/p>\n

This phenomenon isn\u2019t limited to the UK. Something similar has been happening in the U. S., where another large study found that the number of attacks suffered at home had dropped by 40 per cent compared with previous years.<\/p>\n

So what has been going on? Explanations put forward so far include people\u2019s inability to get a face-to-face appointment, or even a reluctance to visit the doctor for fear of being exposed to Covid-19; that asthma medications offer some protection against the virus; and that the pandemic precautions \u2014 masks, distancing, isolation \u2014 have reduced the risk of exposure to other viruses known to trigger attacks.<\/p>\n

Professor Geoffrey Chupp, director of the Center for Asthma and Airways Disease at Yale University, has found that asthmatics, who make up about 10 per cent of the Covid-19 patients in the U.S., were more likely to survive the virus<\/p>\n

It\u2019s certainly true that fear stopped people from seeing a doctor. \u2018Many of our supporters told us they were afraid to seek help during the pandemic for fear of being exposed to Covid,\u2019 says a spokesperson for the Asthma UK and British Lung Foundation Partnership.<\/p>\n

Meanwhile, others simply couldn\u2019t get a face-to-face appointment with their GP.<\/p>\n

But Professor Elliot Israel, a lung specialist at Brigham and Women\u2019s Hospital in Boston, who led the U. S. study, has another theory for the decline in people seeking help for asthma.<\/p>\n

He thinks experts may have concentrated too much on advising patients to avoid substances that trigger allergic asthma attacks, such as pollen, cleaning products or pollution, when it\u2019s other illnesses that may be more problematic.<\/p>\n

\u2018These things can trigger an attack, but what now looks more important is the ability of other viruses to cause these attacks,\u2019 he says.<\/p>\n

During the pandemic, people took precautions that reduced their risk of getting viral infections and, as a result, rates of these infections in general have dropped dramatically.<\/p>\n

Normally, around 50,000 people die from flu in the U.S. every year. In the past year, however, flu caused between 1,000 and 2,000 deaths, he says. The new findings have triggered a debate among experts.<\/p>\n

\u2018We can\u2019t assume that because GPs are seeing fewer patients with asthma attacks that people aren\u2019t having them,\u2019 says the spokesperson for the Asthma UK and British Lung Foundation Partnership.<\/p>\n

\u2018We know that 66.7 per cent of people who had an asthma attack dealt with it at home.\u2019<\/p>\n

In response, Professor Israel points out that his study, which involved 1,000 people with asthma, was designed to report specifically on what happened in their homes.<\/p>\n

\u2018They sent in weekly reports about how they were feeling, what medication they were taking and if they\u2019d had an attack,\u2019 he says. \u2018As the reports came in it was clear the number of attacks had dropped.\u2019<\/p>\n

His theory is backed by Dr Lauren Cohn, a lung specialist and an associate professor of medicine at Yale University.<\/p>\n

\u2018During the pandemic, my patients had fewer flare-ups than in past years,\u2019 she says. \u2018We think this is due to mask-wearing and limited human contact at work and school.\u2019<\/p>\n

So what else could be cutting cases? Professor Geoffrey Chupp, director of the Center for Asthma and Airways Disease at Yale University, has found that asthmatics, who make up about 10 per cent of the Covid-19 patients in the U.S., were more likely to survive the virus.<\/p>\n

\u2018It\u2019s possible that some of the medications used for asthma helped to reduce the inflammation that Covid-19 causes,\u2019 he told Good Health.<\/p>\n

This is because the puffers that people with asthma use to relieve the symptoms of an attack contain low doses of steroids that bring down inflammation, he says.<\/p>\n

It\u2019s also possible that the medication down-regulates the ACE2 receptors found on cells throughout the body, and which the virus uses to get in, making access harder, suggests Professor Israel.<\/p>\n

Dr Shah has another, more conventional, theory: \u2018There is a lot of evidence that asthma improves if the environmental triggers \u2014 pollen, air pollution, cleaning products \u2014 are managed properly.\u2019<\/p>\n

Air quality certainly improved temporarily in cities around the world during the lockdowns. One report found that as emissions from industry and transport fell in 2020, 65 per cent of the analysed global cities experienced better air quality compared to 2019.<\/p>\n

\u2018The cleaner air during the pandemic certainly helped, and as a preventative measure, more asthma patients got inhalers and were encouraged to use them if they had a flare-up,\u2019 says Dr Shah. \u2018So, the pandemic could be causing a drop in flare-ups because people are being more careful about self-management.\u2019<\/p>\n

But Professor Israel disagrees. \u2018I\u2019ve had to rethink my long-held assumption that much of asthma is due to home and office allergens.<\/p>\n

\u2018It doesn\u2019t fit with the fact that attacks didn\u2019t increase, but went down, when people were isolating in homes, which are a rich source of allergens,\u2019 he says.<\/p>\n

\u2018That\u2019s why giving a bigger role to viruses makes sense.\u2019<\/p>\n

The fact there was no drop in the number of people referred to hospital suggests that those who didn\u2019t see their GP were having milder attacks.<\/p>\n

Ironically, the stronger viral connection could mean that those with asthma may have to take physical precautions against the after-effects of the pandemic for longer.<\/p>\n

\u2018This is a rapidly evolving situation, and we are all trying to make sense of different aspects,\u2019 says Professor Israel.<\/p>\n

\u2018The lifting of restrictions means that there is likely to be a rise in the number of all viral infections.<\/p>\n

\u2018Maybe precautions such as masks will have to be kept in place for longer to keep viruses out. They are pretty low-tech at the moment. I suspect there will be a big improvement in that technology soon.\u2019<\/p>\n
