In the published article, there was an error in Table 1 as published. The government organization “Defence Science and Technology Laboratory (Dstl)” should be listed as having both Flowthrough and Rotating types at Biosafety level (BSL)-4 instead of BSL-3. The correct Table 1 appears below. The original article has been updated.
TABLE 1.
Representative set of aerosol test chambers. The list was derived from open source material.
| Organization | Type | Biosafety level | |
|---|---|---|---|
| Academia | Tulane University | Flowthrough | ABSL-3 |
| University of Pittsburgh | Flowthrough | BSL/ABSL-3 | |
| Commercial | CUBRC-Avarint | Static, Flowthrough | BSL-1, 2 |
| Battelle | Flowthrough | BSL-3 | |
| Lovelace Respiratory Research Institute (LRRI) | Flowthrough | BSL-3/ABSL-3 | |
| MRIGlobal | Static, Flowthrough | BSL-3 | |
| Government | Dugway Proving Ground | Static, Flowthrough | BSL-3 |
| National Biodefense Analysis and Countermeasures Center (NBACC) | Static, Flowthrough, Rotating | BSL-3 | |
| U.S. Army Medical Institute for Infectious Diseases (USAMRIID) | Static Flowthrough | BSL/ABSL4 | |
| Defence Science and Technology Laboratory (Dstl) | Flowthrough, Rotating | BSL-4 | |
In the published article, the reference for Beedham and Davies, 2021 was inadvertently included in the last sentence of the last paragraph in the section, “Examples of Related Aerosol Test Chamber Work”. It should be added to the preceding sentence of the same paragraph in the same section.
The sentences previously stated:
“Similar to the United States, foreign governments have entities that focus on infectious disease, to include BWA. An allied counterpart in the United Kingdom is their Defence Science and Technology Laboratory (Dstl) which the Ministry of Defense operates at Porton Down. Prior to the COVID 19 outbreak, Dstl conducted numerous studies using a Rotating Drum to study the stability and viability of aerosolized infectious diseases, including Lake Victoria Marburgvirus, Zaire ebolavirus, and Reston ebolavirus (Piercy et al., 2010, Schuit et al., 2014). Following the COVID 19 outbreak, Dstl used this same capability to study SARS-CoV-2 in saliva and different media at various humidity (Smither et al., 2020; Beedham and Davies, 2021).”
The corrected sentences appear below:
“Similar to the United States, foreign governments have entities that focus on infectious disease, to include BWA.
