Proposed Data Collections Submitted for Public Comment and
Recommendations
In compliance with the requirement of Section 3506(c)(2)(A) of the
Paperwork Reduction Act of 1995 for opportunity for public comment on
proposed data collection projects, the Centers for Disease Control and
Prevention (CDC) will publish periodic summaries of proposed projects.
To request more information on the proposed projects or to obtain a
copy of the data collection plans and instruments, call 404-639-4766
and send comments to Seleda Perryman, CDC Assistant Reports Clearance
Officer, 1600 Clifton Road, MS-D74, Atlanta, GA 30333 or send an e-mail
to [email protected].
Comments are invited on: (a) Whether the proposed collection of
information is necessary for the proper performance of the functions of
the agency, including whether the information shall have practical
utility; (b) the accuracy of the agency's estimate of the burden of the
proposed collection of information; (c) ways to enhance the quality,
utility, and clarity of the information to be collected; and (d) ways
to minimize the burden of the collection of information on respondents,
including through the use of automated collection techniques or other
forms of information technology. Written comments should be received
within 60 days of this notice.
Proposed Project
Aerosol Generation by Cough--NEW--The National Institute for
Occupational Safety and Health (NIOSH), Centers for Disease Control and
Prevention (CDC).
Background and Brief Description
The Federal Occupational Safety and Health Act of 1970, section
501, enables NIOSH to carry out research relevant to the health and
safety of workers. NIOSH is conducting a two-year study of airborne
clouds of particles or droplets called ``aerosols''. Some diseases like
influenza and Severe Acute Respiratory Syndrome (SARS) can be spread
when people produce infectious aerosols by coughing or sneezing.
Aerosol transmission of infectious diseases is especially important to
health-care workers and emergency responders, who face a much greater
risk of exposure to these hazards than does the general public. Cough-
generated aerosols are of particular concern because coughing is one of
the most common symptoms of respiratory infections. However,
substantial gaps exist in our understanding about the generation of
aerosols during coughing. This lack of information hampers the ability
of health scientists to model and predict the generation of infectious
aerosols by coughing and to understand whether or not cough-generated
aerosols are likely to be an important means of transmission of
particular diseases.
The purpose of this study is to gain a better understanding of the
production of aerosols by coughing. The results of this research will
give scientists and health professionals greater insight into the
airborne transmission of disease and allow them to better assess the
potential effectiveness of preventive measures.
The first part of this study will measure the quantity and size
distribution of aerosol produced during human coughs. To accomplish
this, volunteers will cough into a spirometer, which is a commonly used
piston-like medical device that measures the volume of air exhaled by a
patient. After the volunteer coughs into the spirometer, the air in the
spirometer will be drawn into a commercial aerosol measurement device.
These experiments will also provide information on how much cough
aerosols vary over time for individuals and how much aerosol generation
varies between individuals.
The second part of this study will determine how effectively
surgical masks and N95 respirators block cough-generated aerosols. N95
respirators are dust masks that are certified to filter out at least
95% of airborne material during normal breathing. N95 respirators are
known to be more effective than surgical masks at filtering out
airborne particles during inhalation, but it is not known whether masks
or respirators are more effective at blocking cough-generated aerosols.
For this work, masks and respirators will be placed in a special holder
with a disposable mouthpiece, and human subjects will cough into the
mouthpiece and through the mask. The aerosol produced by each subject
will be analyzed before and after flowing through the mask. These
experiments will determine how effective each mask or respirator is at
preventing the release of cough-generated aerosols.
Volunteers from part 1 may also participate in part 2 if they wish.
There will be no costs to study participants other than their time.
