The Department of Health (DOH) on Friday said they are looking at releasing an advisory against allowing church choirs to avoid possible transmissions of COVID-19.

Health Undersecretary Maria Rosario Vergeire said that they will be studying its risk especially as it is a common practice among churches nationwide.

“Isa yan sa dapat pag-aralan and mapagsabihan din of course ang ating mga ka-parian at simbahan that this might be a cause of spreading the virus as well,” she said.

“This is still a venue of transmission and siguro magkaroon tayo ng advisory sa ating mga simbahan regarding this matter,” she added.

This also comes as part of the protocols in the yuletide season where singing through karaokes and videokes have already been banned in most areas.

In a study published at the United States National Center for Biotechnology Information, it was stated that the amount of particles transmitted is amplified by the loudness of the voice which could reach as high as 50 particles per second.

This was likewise stated in a study conducted by the US Central Disease Control and Prevention (CDC) in a specific choir practice where around 87 percent of the group developed COVID-19 including two fatalities with just one symptomatic person.

As explained the two and half hours of singing practices was said to have provided more opportunities for the droplet transmission which was even made worse by their lack of physical distancing.

“Aerosol emission during speech has been correlated with loudness of vocalization, and certain persons, who release an order of magnitude more particles than their peers, have been referred to as super emitters and have been hypothesized to contribute to superspreading events,” it stated.

At present, the DOH has already advised the public against using trumpets and whistles apart from singing and holding social gatherings especially during the yuletide season as it poses a higher risk of COVID-19 transmission.

Individuals are instead told to use alternative noise-makers and to celebrate the holidays only within members of the household to avoid the expected surge of cases.

To date, the Philippines has already exceeded the 445,000-mark of COVID-19 cases as research members of the OCTA team project cases to go as high as 500,000 by end-December if the current trend will continue.
