Around the world, many health agencies have concluded, based on a number of studies, that the coronavirus can be spread through airborne transmission of microscopic particles to people who are more than 6 feet away under certain conditions. Yet, Canada has not followed the lead in updating its COVID-19 guidelines, according to CBC Canada.
From its onset, it was believed that the coronavirus was only spread by large droplets that supposedly fell to the ground within an area of 2 meters, or 6.5 feet. Then, scientists learned the virus could also be transmitted when in close personal contact with an infected person, such as shaking hands.
And as the pandemic has continued to spread around the world, scientists have learned a lot more about this novel coronavirus, including how it has evolved and how it is changing. It is important to remember that this particular virus is totally new to humankind, so everything we learn as time goes on is necessary to maintaining our health.
In July, the World Health Organization (WHO) came under fire after 239 scientists from 32 countries wrote an open letter calling on the United Nations agency to update its guidelines to include that the coronavirus can be transmitted by airborne particles.

The WHO and CDC revise their guidelines
Just a few days later, WHO updated its guidelines to include an acknowledgement that small airborne droplets, known as aerosols, can lead to outbreaks of COVID-19 in places like choir practices, restaurants and fitness classes.
The revised WHO guidelines also note that “transmission may also occur indirectly through touching surfaces in the immediate environment or objects contaminated with virus from an infected person (e.g. stethoscope or thermometer), followed by touching the mouth, nose, or eyes.”
The U.S. Centers for Disease Control and Prevention (CDC) again updated its guidelines on Monday to say COVID-19 can sometimes be spread by airborne transmission, after mistakenly posting and later removing a draft version of guidelines. The CDC and WHO join a growing list of countries, like Germany and Italy, that now acknowledge the transmission of the virus through aitborne particles, or aerosols.

“I was happy and relieved, because now they’re acknowledging the best available science that we have,” said Linsey Marr, an expert in the transmission of viruses by aerosol at Virginia Tech. “You’re not going to be able to bend the curve unless you pay attention to this transmission route.”
No plans to update guidelines in Canada
The Public Health Agency of Canada’s (PHAC) guidelines make no mention of aerosol transmission and instead say the virus spreads only through breathing in respiratory droplets, touching contaminated surfaces and common greetings like handshakes and hugs.
PHAC told CBC News it is not updating its guidance on airborne transmission — even though it admits aerosol spread has happened. “Aerosol transmission of COVID-19 in ventilated and unventilated environments continues to be studied,” a statement from the federal agency stated. “There have been situations where aerosol transmission in closed settings has occurred.”

Coronavirus: Who is most likely to suffer long Covid symptoms? – AlKhaleej Today
Thank you for reading the news about Coronavirus: Who is most likely to suffer long Covid symptoms? and now with the details
Scientists in the UK have uncovered the risks of suffering the phenomenon known as ‘long Covid’ – long-lasting symptoms of Covid-19.
King’s College London researchers estimate that one in 20 people are sick with the novel coronavirus for at least eight weeks.
They say old age and a wide array of initial symptoms increase the risk of enduring Covid-19 for an extended period of time.
Being female, overweight and having asthma also increases the risk of suffering ‘long Covid’.
The research, which uses data from the Covid Symptom Study App currently being used by 4.3 million Britons, suggested ‘long Covid’ affects around 10 per cent of 18 to 49-year-olds who become indisposed with coronavirus.
Public Health England (PHE) discovered that around 10 per cent of people with Covid-19, who were not hospitalised, had revealed symptoms lasting more than four weeks.
The symptoms of long Covid include extreme fatigue, prolonged loss of taste or smell, respiratory and cardiovascular symptoms, and mental health problems.
They also include hair loss, pain and inflammation throughout the body, rashes and blood-clotting issues.
According to BBC News, scientists scoured the data for patterns that could predict who would get long-lasting illness.
The results, which are set to be published online, illustrate that long Covid can affect anyone, but some factors do increase the risk.
“Having more than five different symptoms in the first week was one of the key risk factors,” Dr Claire Steves, from Kings College London, told BBC News.
As per BBC News’ report, somebody who had a cough, fatigue, headache and diarrhoea, and lost their sense of smell – which are all potential symptoms – would be at higher risk than somebody who had a cough alone.
The risk also rises with age – particularly over 50 – as did being female.
Dr Steves said: “We’ve seen from the early data coming out that men were at much more risk of very severe disease and sadly of dying from Covid, it appears that women are more at risk of long Covid.”
No previous medical conditions were linked to long Covid except asthma and lung disease.
Fatigue is common in long-Covid sufferers, but symptoms vary from one patient to the next.
The exact symptoms of long-Covid vary from one patient to the next, but fatigue is typical.
Vicky Bourne, 48, started off with a fever and a “pathetic little cough” in March, which became “absolutely terrifying” when she struggled to breathe and needed to be given oxygen by a paramedic.
She was not hospitalised but is still – in October – living with long Covid.
Vicky’s health is improving, but her vision has changed and she still gets “waves” of more serious illness. Even walking the dog makes her suffer, so much so that she can’t talk at the same time.
She told the BBC: “I have strange, almost arthritic joints and weirdly, two weeks ago, I lost my sense of taste and smell again, it just went completely.
“It’s almost like there’s inflammation in my body that’s bouncing around and it can’t quite get rid of it, so it just pops up and then it goes away and pops up and goes away.”

Hospitals struggle as 20 European countries record highest daily number of COVID cases – ABC News
Europe’s coronavirus second wave is in full swing with 20 countries on the continent, including the UK, Italy and Switzerland, reporting record numbers of COVID-19 infections.
- At least 20 European countries have recorded their highest daily number of new COVID-19 infections
- Europe has recorded more than 5 million cases and 200,000 deaths linked to coronavirus
- Authorities are worried that hospitals will not be able to cope with the second wave
The UK topped the list with 26,668 new cases and 191 coronavirus-related deaths in the previous 24 hours, while Italy recorded an additional 15,199 infections, up from its previous record of 11,705 on Sunday.
The Czech Republic saw an increase of 11,984 cases on Wednesday, while Poland recorded 10,040 and Switzerland had 5,596 new infections.
The records are following a worrying trend in Europe which is forcing governments to reintroduce restrictions on social interaction and hospitality services throughout the continent.
According to data from the European Centre for Disease Prevention and Control (ECDC), Europe has registered more than 5 million cases and 200,000 deaths, with new cases beginning to rise sharply from the end of September.
Meanwhile, Spain has become the first western European country to reach more than 1 million confirmed cases after reporting 16,973 additional cases in the past 24 hours.
The country has 34,366 confirmed deaths.
European Union leaders will hold a video-conference next week to discuss how to better cooperate as the infections rise.
Hospitals struggle to cope
With case numbers that were brought largely under control by lockdowns in March and April now surging, authorities in countries from Poland to Portugal have expressed mounting alarm at the renewed crisis confronting their health infrastructure.
Belgium, struggling with what its health minister called a “tsunami” of infections, is postponing all non-essential hospital procedures, and similar measures are looming in other countries where case numbers have been rising relentlessly.
“If the rhythm of the past week continues, rescheduling and suspending some non-priority activities will become unavoidable,” Julio Pascual, medical director at Barcelona’s Hospital del Mar, told Reuters.
European countries boast some of the world’s best health services and doctors say that with the benefit of almost a year’s experience with coronavirus, they are much better equipped to treat individual patients clinically.
But the capacity of hospitals to handle a wave of COVID-19 patients, as well as people suffering from cancer, heart disease and other serious conditions, is still vulnerable.
Dutch health authorities said if the number of COVID patients in hospital wards continues to grow, three quarters of regular care may have to be scrapped by the end of November, and there were similar warnings from Czech authorities.
“We have hit a wall on clinical beds,” Wouter van der Horst, spokesman for the Dutch hospital association NVZ, said.
‘We couldn’t get to everyone’
As hospital admissions have spiralled, much attention has been focused on intensive care units, which came close to being overwhelmed in many areas during the first wave of the crisis.
On Wednesday authorities in Lombardy, the Italian region at the centre of the first wave of the pandemic, ordered the reopening of special temporary intensive care units set up in Milan and Bergamo that were shut down as case numbers receded.
Already, a number of regional health authorities in Germany, one of the countries that dealt with the first wave most effectively, have agreed to take in intensive care patients from other countries.
The ECDC said that some 19 per cent of patients diagnosed with COVID-19 are estimated to have ended up in hospital and eight per cent of those could require intensive care, but variations are wide both across Europe and within individual countries.
On Wednesday, Poland’s Health Minister said up to 30 per cent of new cases there could end up being hospitalised.
There has also been concern over the track and trace systems meant to keep local outbreaks of the disease under control but those systems have proven ineffective in many areas.
Authorities in Ireland, where the five-day case average has tripled since the start of October, said there were no longer enough officials to keep the system working.
Niamh O’Beirne, national lead for testing and tracing, told RTE radio that contact tracing centres had seen “unprecedented demand” with exponential growth in the number of cases, “and over the week we simply couldn’t get to everyone”.
