Test Track Trace

The never ending bullshit and contradictions and confusion will continue as we reel from crisis to crisis.  This is not about Covid, it is about Unemployment, a return to some type of structure with regards to business, education and of course all the other bullshit from stimulus packages to those getting loans, checks or well any questions answered.

Again we have super spreaders, contact surface tests and my favorite the projectile spit skills that have come up with the 6 feet mandate.  This one I love as who in the fuck is getting from spit from six feet away (aka two Golden Retrievers) that is one hell of a powerful loogie.  Again the WHO found that the CDC test was with a device that has not been blind tested or actually replicated in the field but hey its science lets go with it.  And they also use the correct phrase Physical Distancing to explain the needed skill to go along with the request.   But in America we hate WHO as why?  A Black man with a very challenging last name runs the organization.

And there is this from again another study I found which may explain why despite all the measures in quarantining and self isolating the numbers stay relatively high.  "The most significant finding from our study is that half of the patients kept shedding the virus even after resolution of their symptoms,"  The authors had a special message for the medical community:    "COVID-19 patients can be infectious even after their symptomatic recovery, so treat the asymptomatic/recently recovered patients as carefully as symptomatic patients." 

And again we have varying time frames from contact to symptomatic.  And here too is another variation of information that we may or may not be given. The time from infection to onset of symptoms (incubation period) was five days among all but one patient. The average duration of symptoms was eight days, while the length of time patients remained contagious after the end of their symptoms ranged from one to eight days. Two patients had diabetes and one had tuberculosis, neither of which affected the timing of the course of COVID-19 infection.

I read most of my daily update from the usual sources the New York Times, the Washington Post, the Guardian and PBS.  However I actually read scientific journals and more wonky nerdy sites like Science Live to further educate and inform as well as check the stats, the info and then of course ask the Politicians where they got their info to see if it in fact checks.  They are only using the CDC and that they are also extrapolating data and misquoting it is another issue but then again they never get back to me on that when I cite their sources and provide links.  Funny how that works.

The reality is that we have the CDC and WHO where both have been in conflict from day one so I trust neither and read both as my own way of tracking and tracing this chaos.  We read endless reports from varying sources of testing across the globe and my favorite was Covid Feet and Covid Testicles  which to decide is better is well up to you. But largely the remain similar to how viruses are spread and what to do to protect yourself from contracting Covid.  And yes are the same for any virus and yet we seem to think this is a whole new thing. No just the affects of the virus varies on a case by case basis and has had severe health problems leading to death for many who fall into a larger classification of at risk.   Oddly children usually fall into this but this is the one time I hear very little about the disease and what may mean why this disease is still rampant given our lockdowns.  We should be declining and we are but until EVERY SINGLE PERSON and CONTACT TRACE and in turn quarantine the at risk while this is ongoing we have well this fucked up hot mess.

As this is clear:  Other known symptoms of COVID-19 include fever, fatigue, cough and difficulty breathing. Respondents in Yan's study were most often persons with milder forms of COVID-19 infection who did not require hospitalization or intubation. The findings, she said, underline the importance of identifying early or subtle symptoms of COVID-19 infection in people who may be at risk of transmitting the disease as they recuperate within the community.  

**ya think kids had some of this and are fine now? I do. Covid has been with us for awhile now.   Again it is a virus and we have had many pass over our shores but we had leadership that was competent and agencies that had actually educated and trained individuals running them. Here in Jersey City our Health and Human Services coordinator is Harvard educated; however, she has a degree in Business and Economics and her single gig before was running the WIC program in NYC. Perfect person to be leading a department of health during a pandemic!



Coronavirus: contact tracing explained

WHO says Covid-19 patient tracing should be ‘backbone of the response’

What is contact tracing?

This is one of the most basic planks of public health responses to a pandemic. It means literally tracking down anyone that somebody with an infection may have had contact with in the days before they became ill.

It was – and always will be – central to the fight against Ebola, for instance. In west Africa in 2014/15, there were large teams of people who would trace relatives and knock on the doors of neighbours and friends to find anyone who might have become infected by touching the sick person.

Is it harder to do in the case of a respiratory infection?

Most people who get Covid-19 will be infected by their friends, neighbours, family or work colleagues, so they will be first on the list. It is not likely anyone will get infected by someone they do not know, passing on the street.

It is still assumed there has to be reasonable exposure – originally experts said people would need to be together for 15 minutes, less than 2 metres apart. So the contact tracer will want to know who the person testing positive met and talked to over the two or three days before they developed symptoms and went into isolation.

What do the contact tracers do then?

In the way it was operating in February, the tracer would call the contacts and ask them how close they had been to the person with symptoms and establish whether they were low-risk or high-risk. If the latter, they would be asked to isolate themselves for 14 days at home.

The contact tracers would either call each day to check how they were or ask them to phone if they felt ill. If they developed symptoms, the tracers would start again, looking for their contacts in turn.

Who does the contact tracing?

It is organised by Public Health England, which had 290 staff doing it before community testing stopped in mid-March. Public health in recent years has been the responsibility of local government, so any increase in contact tracers might come from councils.

Which other countries have done this to scale?

South Korea has large teams of contact tracers and notably chased down all the contacts of a religious group, many of whose members fell ill. That outbreak was efficiently stamped out by contact tracing and quarantine.

Singapore and Hong Kong have also espoused testing and contact tracing and so has Germany. All those countries have had relatively low death rates so far. The World Health Organization says it should be the “backbone of the response” in every country.
