\n Not to be a party pooper, but the \u201cHappy Birthday\u201d song may be the latest COVID casualty.<\/p>\n

Despite early advice to sing \u201cHappy Birthday\u201d while hand-washing to ensure sufficient cleansing, health experts are now warning that the song may be a particularly potent vehicle for the spread of COVID-19.<\/p>\n

Researchers at Lund University in Sweden observed the trajectory of aerosols emitted by 12 people singing different songs, and discovered that consonant-heavy lyrics, such as the hard Ps and Bs of the birthday song, send comparatively more droplets into the air.<\/p>\n

\u201cDifferent restrictions have been introduced all over the world to make singing safer,\u201d said Jakob L\u00f6ndahl, an associate professor of aerosol technology<\/a>. While previous case studies have revealed superspreader events seemingly caused by singing, \u201cthere has been no scientific investigation of the amount of aerosol particles and larger droplets that we actually exhale when we sing,\u201d the author said in a statement on the university website.<\/p>\n

Respiratory droplets, which may become aerosolized \u2014 meaning small enough to be carried in the air \u2014 are expelled as we talk, and even more so when we laugh, yell or sing.<\/p>\n

\u201cSome droplets are so large that they only move a few decimeters from the mouth before they fall, whereas others are smaller and may continue to hover for minutes,\u201d said co-author and doctoral student Malin Alsved.<\/p>\n

\u201cIn particular, the enunciation of consonants releases very large droplets and the letters B and P stand out as the biggest aerosol spreaders,\u201d said Alsved, whose experiment used Swedish children\u2019s song, \u201cBibbis pippi Petter.\u201d The song bears similarities in the amount plosive sounds, or those emitted by the consonants T, K, P, D, G and B, as the American \u201cHappy Birthday\u201d song.<\/p>\n

Their study included data from two singers who had tested positive for the coronavirus.<\/p>\n

\u201cTheir air samples contained no detectable amount of virus, but the viral load can vary in different parts of the airways and between different people,\u201d Alsved explained. \u201cAccordingly, aerosols from a person with COVID-19 may still entail a risk of infection when singing.\u201d<\/p>\n

\"During<\/img>
During the tests, singers sang into a funnel. The aerosol particles were measured at the other end.<\/span>Malin Alsved<\/span><\/figcaption><\/figure>\n

However, face masks, social<\/a> distancing and proper indoor ventilation can help prevent singing-induced sickness, according to study authors, who hope their report will help better inform choirs and choral groups on how to sing safely during the COVID-19 pandemic.<\/p>\n

\u201cWhen the singers were wearing a simple face mask this caught most of the aerosols and droplets and the levels were comparable with ordinary speech,\u201d said L\u00f6ndahl, whose report was published in the journal Aerosol Science<\/a> and Technology. \u201cSinging does not need to be silenced, but presently it should be done with appropriate measures to reduce the risk of spreading infection.\u201d\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
