It’s a bad sign when positivity percentage of COVID testing reach nearly 100%. Only happened during Jan 2022 first Omicron surge with a lot higher PCR testing then. Abysmally low PCR testing since Biden admin stopped funding free PCR tests in Mar 2022, shutdown mass testing sites

We found that 12/100 camel handlers and their family members in Pakistan, a country with extensive camel MERS-CoV infection, were seropositive, indicating that MERS-CoV infection of these populations extends beyond the Arabian Peninsula. (2019) ncbi.nlm.nih.gov/pmc/articles/P…

Important new study from a very influential assay inventor. Circulating viral proteins (mostly spike) found in the blood of ~2/3 with long-COVID, but not found in people fully recovered from COVID. Consistent with- but not proving- ongoing viral reservoir. academic.oup.com/cid/advance-ar…

Viruses are always changing. How specifically “SARSCoV2” is defined is relevant to questions about “origin”, & #testing_limitations need consideration. For example, here the cutoff of 30% inhibition of SCV2 by blood antibodies is somewhat arbitrary. The distribution is…


I think they tested twice with two methods, and the 2019 sample was positive by the cutoff they used with one test, but negative for the other. There are some #testing_limitations that make interpretation tricky, that’s true. The 2019 sample was collected in February of that…

BTW: Metagenomic next-generation sequencing (mNGS) also diagnosed the pathogen🦠threatening this patient's life - 🧪lab cultures🧫 missed it. As per "GeneBank," GZMB variants have previously been linked to 'Severe Cutaneous Adverse Reaction' and 'Papillon-Lefevre Syndrome.'

3 years ago, in late March, 2020, NYC was only testing for covid in people who were hospitalized. Prevalence of covid, historically, is often underestimated because of such #testing_limitations. #SARSCoV2_timeline #Spring2020 #testing_criteria #data_collection

Don't know... The data in the article is from 3/19, a lot has changed. NYC is now only testing people who are in the hospital. Latest report:

1. different animal reservoirs 2. geography (island/contained circulation vs open) 3. difference in community immune system profile, specifically US with more immune-suppression so change in ORF-9 confers less/no advantage 4. #testing_limitations

It is very inconsistent. What grinds my gears - when data from Spring 2020 is reported as if it represents the first spread of SARS-COV-2 during that time. But the data is really representative of the spread of covid tests, and says more about #testing_limitations than community…
