Coronavirus: Alarming video reveals virus-laden particles created by singing

coronavirus alarming video reveals virus laden particles created by singing

Researchers in Australia believe singing, especially in a choir, could spread coronavirus via airborne droplets. 

The findings come from a slow-motion video with special LED lighting which shows how otherwise invisible particles shoot from the mouth of a singer. 

During an experiment, a person was asked to sing a popular scale and some sounds, such as ‘do’, ‘fa’ and ‘ti’, forced particles out at up to six metres a second (13 mph). 

More than half of droplets produced by coughing travel at this speed, or faster, while only 15 per cent of particles created by talking travel at this pace.   

Researchers suggest that extra precautions should be taken to mitigate against the extra dangers posed by group singing. 

This includes rehearsals with fewer people, wearing face coverings while singing and extreme social distancing.

During an experiment, a person was asked to sing a popular scale and some sounds, such as ‘do’, ‘fa’ and ‘ti’, forced particles out at up to six metres a second (13 mph) 

A recent piece of research found the amount of particles produced is the same, but did not account for speed. 

This finding led researchers to believe singing was just as risky as talking, but the new research indicates singing poses extra risks. 

For example, the quantity of particles produced when singing could saturate the air inside a room, making social distancing pointless. 

A study from the university of New South Wales, Sydney, found the majority of particles produced during singing travel at less than 0.5 m/s.

However, they are spewed in all directions and are likely to not settle and drift on air currents. 

In a room with air conditioning or a fan this would see the infectious particles stay airborne for long periods of time, travelling vast distances.  

For the study, the singer remained at a relatively subdued sound range of between 66 and 72 decibels.

Singing in a choir has been heavily linked to previous superspreader events. Outbreaks at choirs in Berlin, Amsterdam and Washington were so severe that 75.6 per cent, 78.5 per cent and 86.9 per cent of people in attendance tested positive for COVID-19, respectively (stock)

‘It is also worth noting that some degree of variability is expected in the number of droplets expelled between different individuals, and due to other parameters, such as loudness, notes, consonants, and duration of each note sung,’ the researchers say in the study, published today in Journal of Infectious Diseases.

Outbreaks at choirs in Berlin, Amsterdam and Washington were so severe that 75.6 per cent, 78.5 per cent and 86.9 per cent of people in attendance tested positive for COVID-19, respectively.  

‘The data presented combined with high infection rate among the choir members points towards the possibility of airborne spread of COVID-19 during singing events,’ the researchers write.  

The study is the latest in a string of scientific papers investigating the danger singing poses in regard to the transmission of Covid-19.

Researchers at Lund University, Sweden studied the amount of particles emitted when we sing and found loud and consonant-rich tunes, such as Happy Birthday, spread a lot droplets into the surrounding air.  

SAGE WARNED GOVERNMENT ABOUT SINGING DURING CRISIS 

The Government’s Scientific Advisory Group for Emergencies (Sage) earmarked live musical performances and choirs were one of the more risky events for Covid.

This was why music venues, indoor theatres and concerts were the very last amenities to reopen following lockdown.

In a report submitted sometime in June, SAGE said it had reviewed a number of international studies and found evidence to suggest that singing can produce more aerosols, or droplet nuclei, than normal talking or breathing.

Covid-19 is spread through respiratory secretions, which can take the form of large droplets or smaller aerosols.

These are either inhaled directly or transferred by the hands from surfaces where they have been deposited.

The document says that the smaller the particle, the further it can advance into the respiratory tract.

The authors said: ‘There exists some evidence to suggest that singing can produce more aerosols than normal talking or breathing; it may be more akin to a cough.

‘Singing for any appreciable amount of time therefore may present a risk for the creation of infectious aerosols and allow for infection transmission.’ 

The authors added: ”Therefore, at the present time the safest way for groups to sing together is to i) sing outside, ii) use the 2m rule to socially distance and iii) avoid face-to-face positioning.’

Blue Moon: Once-in-19-years event to occur on Halloween night

blue moon once in 19 years event to occur on halloween night

Legend has it that ghosts and spirits are more active on Halloween, but these ghoulish entities are not the only things coming out on October 31 – a rare Blue Moon is set to rise on the same day. 

The full moon phase, which is the lunar orbs position in in orbit, begins on Saturday at 10:49am ET.

Earth’s natural satellite will not shine blue, but bares the name as it is the second full moon to appear this month – the first occurs October 1.

The cosmic display happens seven times every 19 years, which means the world will not see the next one on October 31 until 2039.

However, this is the first time a Blue Moon has appeared across the world on Halloween since World War II.

It should make for a spectacular show on Halloween that has not happened since 1944.

People in North and South America will have a glimpse of the Blue Moon, along with those in India, Europe and Asia.

The idea of a Blue Moon as the second full moon in a month comes from an article in the March 1946 issue of Sky and Telescope magazine.

This issue published an an article called Once in a Blue Moon by James Hugh Pruett, who referred to the 1937 Maine Farmer’s Almanac, but with a simpler definition.

‘Seven times in 19 years there were – and still are – 13 full moons in a year,’ he wrote.

‘This gives 11 months with one full moon each and one with two.’

‘This second in a month, so I interpret it, was called Blue Moon.’

A moon can turn blue, but the signing is very rare.

NASA shares that this is also deemed the Hunter’s Moon, the full moon that follows the Harvest Moon that appeared on October 1. 

‘According to the Farmer’s Almanac, with the leaves falling and the deer fattened, this was the time to hunt. Since the harvesters had reaped the fields, hunters could easily see the animals that have come out to glean (and the foxes that have come out to prey on them),’ reads NASA’s statement.

‘The earliest use of the term ‘Hunter’s Moon’ cited in the Oxford English Dictionary is from 1710.’ 

On Halloween night, Jupiter will appear in the southwest and Mars will shine brightly in the east-southeast.

However, at 2am ET we ‘fall back’ one hour to 1am ET -but the good news is, you will have an extra hour of sleep.
