Different Types or Lineages of the SARS-CoV-2 Virus

[Rena]

Rena, it is necessary for our Scientists and Specialists to fully understand it. It is a "novel " or unique virus.

You can say that again !!

Yes Mazi maintaining a healthy stomach, gut and bowel function also seem high on the list, as it has always been. It is known Covid-19 can affect other organs.

Dr Michael Mosley, TV Documentary Writer and Broadcaster is a big believer in the human gut function.

In the Summer I heard of "Genomes" and "Sequencing" in relation to SARS CoV-2 the Virus which causes the illness Covid-19.

I don't fully understand Human DNA, but was left with the feeling the current Virus might have its own Lineages (like we can use DNA to help trace Human lineages)?

I've kept an eye on this story and found this today dated 2nd October 2020

This story about the Quadram Institute, England, is making the news today.

Apparently, this Genome sequencing is the most advanced technology in the World for tracing the spread of the disease.

Where they have both samples, they can tell where you caught Covid-19 from and other information according to the BBC.

Coronavirus has its own Genome Sequencing, like our Family DNA Lineages.

The way the Italians are dealing with Covid-19 cases, they seem to think the 14 days isolation period is not fixed and isolation in some cases should be much longer than 14 days and also the individual must be retested and not assumed to be Negative at 14 days.

At 14 days.
Italy. Resolution of symptoms
Two negative tests at 24 hours interval.
 ----------
To go to Italy you must be confirmed as Negative for SARS-CoV-2 / Covid-19.

Genomic evidence for reinfection with SARS-CoV-2: a case study

https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(20)30764-7/fulltext

by R L Tillett · Cited by 1
12 Oct 2020 — All individuals, whether previously diagnosed with COVID-19 or not, should take identical precautions to avoid infection with SARS-CoV-2. The implications of reinfections could be relevant for vaccine  ...

"The degree of protective immunity conferred by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently unknown. As such, the possibility of reinfection with SARS-CoV-2 is not well understood. We describe an investigation of two instances of SARS-CoV-2 infection in the same individual."

Comment
Seems the difficulty in proving reinfection currently, apparently relies on having the original sample sequence etc., taken when the person tested Positive the first time, then also having a Negative test afterward.

Reinfection means everyone (whether you have had Covid-19, or not) need to follow the same precautions to try to avoid catching it.

Hands, Face, Space everytime,
