Covid 5/26/20

A very promising option for testing – an actual leading indicator –

“We produced a SARS-CoV-2 RNA concentration time course in primary sewage sludge

during a COVID-19 outbreak in the New Haven, CT metropolitan area. Approximately 200,000

people are served by the treatment facility and COVID-19 total documented cases by testing rose

from less than 29 to 2,609 during the March 19 to May 1, 2020 surveillance period. Our results

demonstrate: (1) the utility of SARS-CoV-2 primary sludge monitoring to accurately track

outbreaks in a community and (2) primary sludge SARS-CoV-2 RNA concentrations can be a

leading indicator over other commonly used epidemiology approaches including summarized

COVID-19 test results and hospital admissions.”

“Within the US, approximately 16,000 treatment plants serve more than 250,000,000 people.”

“Jurisdictions can use primary sludge SARS-CoV-2

concentrations to preempt community outbreak dynamics or provide an additional basis for

easing restrictions, especially when there are limitations in clinical testing. Raw wastewater and

sludge-based surveillance is particularly useful for low and middle-income countries where

clinical testing capacity is limited.”

Not only can sewage plants be used to understand the trend in Covid but one could also at least use them to isolate areas/region to allocate more precise testing. This is something they could not do in 1918 – lets be more advance!

US deaths amazingly low but likely due to holiday – 500. Brazil 807

NY leads again with 88. CA leading the way for confirmation.

County view showing the growth in S. Ca and Cook County. For death view besides NYC region – Cook County IL and NV (Washoe and Clark) and LA CA are the prominent ones.

On a global map of death per capita – one can see Sweden sticking out to neighbors – plus Portugal sticking out on the positive end. Many articles discussing Portugal and their ability to quarantine with much less cases vs. Spain. Spain revised death down by almost 2K – not sure what lead to that.

France is dropping quickly in deaths. UK is still gliding down. Brazil and Mexico continue to climb. Russia death has quietly climbed to be higher than Italy – higher than Belgium peak daily death.
