Contact with contaminated surfaces (fomites) followed by touching of the eyes, mouth, or nose is another potential mode of SARS-CoV-2 transmission, although the relative importance of fomite transmission is still poorly understood. But this year, Christmas arrives in the midst of a pandemic that essentially shut down church choirs in mid-March. This document will be updated as further evidence emerges. If infected persons are asymptomatic or pre-symptomatic, they may be unaware that they are emitting infectious particles and presenting a risk to others in the room. 2020;323(18):1837-8. Nearly all 61 members of a choir in Washington state became infected with COVID-19 after a single rehearsal in March, a CDC study found.

These “super-emitters” have been found to release up to an order of magnitude more particles compared to normal emitters.23,36, Release of infectious virus in respiratory particles, As presented above, singing, and loud vocalization could increase risks of transmission via respiratory droplets of all sizes. Nature. (They are all facing towards one direction. Choir singers have been found to have a higher average vital lung capacity than non-singers, and the inspiratory capacity of singers has also been found to be greater on average.29 Children may release fewer respiratory particles due to smaller lungs with fewer terminal bronchioles where production of aerosols via fluid-film burst could occur.

This brief review has outlined the key risks associated with singing in choirs, including the risks associated with gathering in large groups, and the additional risks related to production of small respiratory droplets via vocalization. Moving activities outside wherever possible is recommended. Within two weeks, 30 members had tested positive and another 30 were experiencing symptoms. Early in the response to the pandemic, gathering in groups was identified as high-risk and limits on the number of people gathering was an essential public health tool for reducing community transmission. Available from: Riediker M, Tsai D-H. Estimation of SARS-CoV-2 aerosol emissions from simulated patients with COVID-19 and no to moderate symptoms. Adjusting timings to allow for shorter rehearsals or performances, with fewer people, and more scheduled breaks outside of the rehearsal space can allow for aerosols to disperse or settle. There is also evidence that maintaining 2 metres distance can help to reduce the short-range transmission of small droplets or bioaerosols. In the larynx, oscillation of the vocal folds occurs for voice production. 2020 May;26(5):672-5. The vast majority of COVID-19 outbreaks have been linked to interactions in indoor environments, particularly large group gatherings over prolonged duration. On the day of the concert, thirty members of the choir reported being ill, and in the weeks following, most of the choir members reported being ill. Of the thousand-member audience that watched the concert, subsequent follow-up inquiries with concert goers did not identify widespread transmission. Evidence of short-range aerosol transmission of SARS-CoV-2 and call for universal airborne precautions for anesthesiologists during the COVID-19 pandemic. Because of COVID-19, churches no longer reverberate with song; hymnals are neatly stacked and projection screens blank. Effect of voicing and articulation manner on aerosol particle emission during human speech. Gupta JK, Lin C-H, Chen Q. Characterizing exhaled airflow from breathing and talking. In the light of the restriction that limits singing at indoor services to choirs and performers, many online carol concerts are being organised in which people can sing along at home. Although these events occurred early in the global pandemic, they demonstrate the importance of symptomatic persons, even if only mildly symptomatic, excluding themselves from group activities. J Voice. Further examination of bibliographies of key articles were scanned to retrieve more extensive information, and key authors in the subject area were searched to identify additional relevant citations. The potential for transmission via pre-symptomatic and asymptomatic persons via multiple routes, including respiratory aerosols, has implications for activities such as singing in groups. COVID-19 resources for the Canadian choral community. Production of respiratory droplets and aerosols during speaking and singing, Loud speech and singing, while less forceful than coughing or sneezing, can result in bursts of air releasing respiratory particles large enough to transport viruses.

Surfaces that are frequently touched by many people, such as door handles or faucets, may be more important in fomite transmission compared to objects or surfaces that are only touched incidentally and less frequently. Wellcome Open Research. Other types of barriers may be considered in some situations to limit the spread of aerosols and droplets directly in front of a singer, such as pop shields on microphone stands.46 Other measures that have been suggested include a staggered arrangement of singers in rows, and practices such as tilting the head downwards when singing to limit projection of respiratory particles.46 Further study is needed to identify the impact of these measures on reducing risks of transmission.

Environ Res. As the vocal folds open and close during vocalization, fluid film between them can also rupture, releasing particles.23  Aerosols can also be produced from the oral cavity during speech.24, A combination of processes thus occurs during speaking and singing as release of droplets due to fluid-film burst in the bronchioles varies with inhalation and exhalation, and release of droplets from the larynx may vary depending on vocalization style. J Aerosol Med Pulmon Drug Del. (It is one of the things that should be reviewed. Lancet Infect Dis. Currently, the primary mode of human-to-human transmission for SARS-CoV-2 is considered to be via prolonged close contact with an infected person and their respiratory droplets generated during coughing, sneezing, and other respiratory actions that produce large droplets (> 5 µm diameter).6 Large respiratory droplets can be contained by actions such as mask wearing, respiratory etiquette (covering one’s mouth when coughing or sneezing) and via physical distancing measures that help to ensure there is sufficient distance for respiratory droplets emitted from an infected person to drop to the ground before reaching others. Control measures for fomite transmission include good hand hygiene practices and routine cleaning and disinfection of surfaces. Don't miss out on the latest news and information. At Greater St. Stephen, 60 to 75 people sing in the choir on a normal Sunday. 2020 May 27;142:105832. MMWR Morb Mortal Wkly Rep. 2020;69:606–10. (2019) found a linear correlation between volume of speech and number of respiratory particles emitted.23  Even quiet speech emits more particles than normal breathing and the quantity of emitted particles during all volume of speech are greater than during breathing. During the rehearsal, members reported being well-spaced while rehearsing but socialized and stood close in line for the coffee break. (Anfinrud, Bax, et al., 2020) Vocalization, whether whispering, loud speaking, or singing produces a higher concentration of particles than breathing.22 Respiratory particles released by vocalization are generated by a combination of mechanisms in the bronchioles, larynx, and oral cavity. Available from: Tellier R. Aerosol transmission of influenza A virus: a review of new studies. Respiratory events such as coughing and sneezing have a higher velocity and can release a high concentration of droplets of various sizes but these events have a low frequency compared to breathing, speaking, or extended periods of singing. Edmonton, AB: Choir Alberta; 2020; Available from: Choral Canada. Participating in choirs and bands may lead to increased risk of COVID-19 transmission if proper precautions are not taken.

Groups should avoid singing in closed, unventilated rooms even with distancing measures in place.42, Short of suspending the activity all together, an approach to maintaining good indoor air quality includes reducing indoor emissions by limiting the number of participants and the duration of participation.3 It is more difficult to maintain safe physical distancing in crowded spaces, and occasional encounters less than 2 m are more likely to occur as crowding increases. Jpn J Infect Dis. The ban on singing to prevent COVID-19 transmission, especially during the holiday season festivities, covers church choir groups, the Department of Health said Friday.
