"The CDC recently eliminated isolation periods for people ill and likely
infectious from Covid. Their Healthcare Infection Control Advisory Committee
drafted guidelines weakening infection precautions, particularly regarding
masking. Fortunately, after a wave of public criticism, the guidelines were
sent back to HICPAC for revision.
People are increasingly left to their own devices to protect themselves against
infection. So, what can you do? Mask and improve ventilation. Uniformly,
wearing a well-fitting, effective respirator, such as an N95 certified by the
National Institute for Occupational Safety and Health or an elastomeric
respirator, is the top recommendation. KF94 masks, the Korean standard, are
preferred by many because, while not quite as protective, they use ear loops
rather than over-the-head straps and don’t fit as tightly. KN95s meet the
Chinese standards, but there were more problems with counterfeiting. Project
N95 was a nonprofit I (and many) relied on because they carefully vetted their
products. They have maintained a list of previously vetted products on that
site, although they are no longer supplying masks.
In terms of ventilation, there was a useful webinar recently, “Indoor Air and
Infectious Disease Transmission,” from the University of Toronto. It is now
available online. I turned to speaker Sarah Haines, Ph.D., an expert there in
building engineering, for more information. Her strongest recommendation was to
add a portable air cleaner to your workspace, if possible. The “Clean Air
Delivery Rate,” or CADR, is sometimes listed and might influence your product
choice."
