This is long. But emphasizes a few of the underlying points about masks:
Several times a day, on every possible news outlet, we are bombarded with updates as to the new number of “cases” of COVID-19 in the U.S. and elsewhere. News analysts then use these numbers to justify criticisms of those who dare to reject the CDC’s recommendations with regards to mask wearing and social distancing. It is imperative that all Americans - and especially those in the medical profession - understand the actual definition of a “case” of COVID -19 so as to make informed decisions as to how to live our lives.
Older Americans remember all too well the dread they experienced when a family member was diagnosed with a “case” of scarlet fever, diphtheria, whooping cough (pertussis), or polio. During my career in family medicine, including several years as an Army physician, I have cared for patients with chickenpox, shingles, Lyme disease as well as measles, tuberculosis, malaria, and AIDS. The “case definition” established for all of these diseases by the CDC requires the presence of signs and symptoms of that disease. In other words, each case involved a SICK patient. Laboratory studies may be performed to “confirm” a diagnosis, but are not sufficient in the absence of clinical symptoms.
Having now been privileged to care for sick patients with COVID-19, both in and out of the hospital setting, I am happy to see the number of these sick patients dwindle almost to zero in my community – while the “case numbers” for COVID-19 continue to go up. Why is that?
In marked contrast to measles, shingles, and other infectious disease, “cases” of COVID-19 do NOT require the presence of ANY symptoms whatsoever. Health departments are encouraging everyone and anyone to come in for testing, and each positive test is reported as yet another “new” case of COVID-19!
On April 5, 2020, a small number of state epidemiologists (Council of State and Territorial Epidemiologists (CSTE) Technical Supplement: Interim-20-ID-01) came up with a “surveillance” case definition for COVID-19. At the time, there was uncertainty as to whether or not completely asymptomatic persons could transmit COVID-19 sufficiently enough to infect and cause disease in others. (This notion has never been proven and, in fact, has recently been discounted – cfr “ A Study on the Infectivity of Asymptomatic SARS-CoV-2 Carriers, Ming Fao et al, Respir Med, 2020 Aug – available online through PubMed 2020 May 13, as well as recent reports from the WHO itself). The CSTF thereby justified the unconventional case definition for COVID-19, adding “CSTE realizes that field investigations will involve evaluations of persons with no symptoms and these individuals will need to be counted as cases.”
Hence, anyone who has a positive PCR test (the nasal swab, PCR test for COVID Antigen or Nucleic Acid) or serological test (blood test for antibodies –IgG and/or IgM) would be classified as a “case” – even in the absence of symptoms. In our hospitals at this time, there are hundreds of former nursing home residents sitting in “COVID” units who are in their usual state of good health, banned from returning to their former nursing home residences simply because they have TESTED Positive for COVID-19 during mass testing programs in the nursing homes.
