There are conflicting reports. The CDC doesn't say it's airborne yet there was some Chinese research that says it is. Bill DiBlasio in his latest update said that if someone infected is in a room and leaves the virus is not going to be in the air.But I noticed how he said an hour. What about 2 minutes? What about 10 minutes.Can the droplets be semi-airborne.Somebody gets on a small elevator whose infected and is coughing. Then they leave.A minute later you walk in and there's no one in there. Could you get it from the air?It seems to be unknown. Yes most of those cough droplets fell to the floor (or wall)but are there some tinier ones still in the air for a minuter or two? 1 Likes

Droplets can land in the mouths, noses, or eyes of people who are nearby or possibly be inhaled into the lungs of those within close proximity. The contribution of small respirable particles, sometimes called aerosols or droplet nuclei, to close proximity transmission is currently uncertain. However, airborne transmission from person-to-person over long distances is unlikelyhttps://www.cdc.gov/coronavirus/2019-ncov/infection-control/control-recommendations.html?CDC_AA_refVal=https%3A%2F%2Fwww.cdc.gov%2Fcoronavirus%2F2019-ncov%2Fhcp%2Finfection-control.html 2 Likes

MunoRN, RN Specializes in Critical Care. Has 10 years experience. Mar 12, 2020 There's been no reason to believe that COVID-19 spreads through airborne transmission rather than droplet, and while this variant is new, the coronavirus itself is not and it's transmission characteristics are already fairly well understood. "Airborne" transmission refers to pathogens where it can remain in the air in a viable form for many hours to even days. Coronavirus can spread through the air, potentially farther than the typical 6 feet of droplet transmission given the right circumstances of droplet formation and airflow, but that is significantly different than airborne transmission.Some confusion seems to come from the CDCs recommendation to incorporate some aspects of airborne precautions due since basic droplet precautions don't actually comprehensively stop the transmission of droplet pathogens, they're just mostly effective, and given the impact of this particular pathogen there's sufficient reason try and close the gaps that droplet precautions leave. While it's certainly important to protect against the spread of person-to-person transmission through the air, I think the focus on that lets people forget that transmission through surface vectors is probably far more common in the community.

2BS Nurse Mar 16, 2020 Since we're not testing everyone... does administering a nebulizer treatment in the clinic cause airborne transmission? Should one be wearing a N95 mask when entering the room? 2 Likes
Closed Account 12345 Has 14 years experience. Mar 16, 2020 I read something posted online by a pediatrician last night that said the airborne half life is 2.7 hours.Now, I have no idea of his source or if it's accurate. Something else I read from some govt source that I don't remember said likely airborne, but not to the extent of TB or varicella. I do know this though. If there wasn't a degree of suspected airborne transmission, hospitals wouldn't be requiring N95 masks at $10 or more a pop to care for COVID-19 patients. 0 Likes

NurseJamillah, BSN, RN Specializes in Med-Surg. Has 3 years experience. Apr 2, 2020 The WHO considers nebulizer treatment to be aerosol-generating.From the WHO:"In the context of COVID-19, airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed; I.e., endotracheal intubation, bronchoscopy, open suctioning, administration of nebulized treatment, manual ventilation before intubation, turning the patient to the prone position, disconnecting the patient from the ventilator, non-invasive positive-pressure ventilation, tracheostomy, and cardiopulmonary resuscitation."https://www.who.int/news-room/commentaries/detail/modes-of-transmission-of-virus-causing-covid-19-implications-for-ipc-precaution-recommendationsAnd the CDC has a broader umbrella, referring to suggested uses for N95 as those "procedures that generate aerosols or during which respiratory secretions are likely to be poorly controlled". They also list it under a description of procedures "likely to generate higher concentrations of respiratory secretions or aerosols": https://www.cdc.gov/coronavirus/2019-ncov/hcp/guidance-risk-assesment-hcp.html Edited Apr 2, 2020 by NurseJamillah Typos and added 2nd link 4 Likes

I saw that repeated in various new stories today as well, but it should be noted that the study didn't actually find that it can remain in the air for several hours, they postulated that with small enough droplets (droplets too small to keep a virus viable) and with the right airflow a near evaporated droplet could remain in the air for several hours.I think people put too much faith in the "6 feet" distance, there's never been any evidence that droplets aerosolized by a cough, sneeze, talking, or breathing are limited to 6 feet of flight, it's dependent on the size of the droplets and airflow characteristics. Although aerosolized droplets at least don't have the travelling capabilities of true airborne particles, which can land on a surface and then easily become suspended in the air again when brushed up into the air by walking, setting something on a surface, etc. 1 Likes

There's no definitive list of "aerosol generating procedures" because there's no evidence to support the definition, none, zilch, nada. It makes more sense to consider potential sources of aerosolized droplets as a whole and refer to them as potential aerosol generating events, which includes coughing, sneezing, talking, and even just breathing. There's no basis for utilizing a different level of protection for any of these procedures than for a patient not undergoing these procedures, but is breathing, talking, coughing, etc. 1 Likes
