🧬Detailed public-facing PCR data from a private lab in Queensland, Australia (thankyou🙏) showing #Flu down to 5.8% positivity (about 1 in 17 samples for COVID-19 testing are FluA positive).
•SARS-CoV-2 continues to rise, currently at 16.7% (1 in 6).
•RSV at 7.5% and slowly⬇ Image
🦠Rhinoviruses are, as usual, a major pathogen in causing acute respiratory infection and lab/healthcare-seeking behaviour.
🦠Human metapneumovirus (MPV), parainfluenza viruses (PIVs) and adenoviruses (AdVs) are on a slow rising trajectory Image
😷A reminder that whatever respiratory signs & symptoms bring a patient in for a test/Doctor's visit - many very different respiratory viruses can cause that disease. Only a good pathology laboratory test has a hope of identifying a cause.
😷Respiratory virus data in these tweets are from Sullivan Nicolaides Pathology (SNP) lab weekly report.
😷They service #Queensland, northern New South Wales and wider Darwin area and Alice Springs

A thread listing some studies that have evaluated some rapid antigen tests (RATs) against PCR, each other and sometimes different SARS-CoV-2 variants.
🧪In Australia, the Therapeutic Goods Administration has organised post-market review of RATs.
tga.gov.au/post-market-re…
At writing, there were 97 products of which 5 have been reviewed. This entailed use of cultured virus sensitivity testing.
🧪"Nearly all tests state in their IFU sensitivity values of > 90% for PCR-confirmed specimens. Such statements, being in strong contrast to the results of our study and to other independent evaluations"

😷Australian National #Flu data up to 03JUL22.
🦠lab-confirmed total cases⬆️ (peaked in ~first week of June)
Graphs from: www1.health.gov.au/internet/main/…
😷Yes, there is undoubtedly more testing capacity in Aus after labs beefed up PCR testing for the pandemic.
😷To check if this is a real decline in #flu, we can look at positivity rate, deaths, hospital beds & ICU occupied beds with flu-positive patients
🛏️year to date (YTD from April 2022), 113 54 lab-confirmed influenza deaths (+59 since last fortnight)🛏️YTD, 1,323 sentinel hospital admissions (+334 ⬆️; =normal lag)
🥽YTD, 86 (6.5%) of those admitted to ICU (+26⬆️; =normal lag)

😷 #SARSCoV2 total positive numbers now rising again, as #flu positives decline.
😷#SARSCoV2 rate is ~100/100,000 population for all age groups and steady while for #flu, it varies by age, up to ~60/100,00 for those aged 0-9 years, and declining
😷In terms of emergency department presentations, #flu-like illness is declining while #COVID19 presentations have stopped declining - slight⬆
