The Bbc News Today - Virus Symptoms

Apc2604Very interesting. Both OH and I were ill in January with flu like symptoms, temperatures and sorethroats. He had a dreadful dry cough. I had a cough and then a chest infection. i am still getting sore throats and nasal problems.
As Robinia said, if we had symptoms like that now we would think it was Corona Virus. Actually OH ended up in A&E (sent by 111) because his whole body came up in a nasty rash. The doctors found nothing significant and said it was a reaction to the illness and this sometimes happens. A&E was packed with people coughing!
And today this is in the news and I am more convinced!

apc I have had covid-19 ( positive test) and had a rash. The rash put the doctors off at first, they thought I had Measles. I got a test as I'm classed as in the high vulnerability group. I still have remnants of the rash which was on my legs and arms but not itchy. Apparently its the immune systems reactions to fighting a virus.
APJ. This is exactly what the doctors said - This was before the awareness of Covid. Early part of January. The rash wasn't itchy but it covered his whole body except for face. He had blood tests for allergies and nothing showed up. The doctor said it was uduslly younger people that had virus reaction allergies!
It will be useful to have an antigen test once they have a vaccine -pointless wasting a vaccine on someone who has already had the virus. Until scientists can say for sure that once you've had the virus you will not get it again, its of little value to know you have had it , and could be counter-productive.
Good point, APG.
‘ Theoretically, people who get COVID-19 should develop corresponding antibodies. However, it is difficult to say at this stage how these antibodies will respond to a future infection.’

Relieved to see that there's also an emerging consensus that short-term immunity, at least, is a thing -- reports of people testing positive twice are now being attributed to presence of "dead" material. While that question was open it was hard to know if there was any point in either antibody tests or a vaccine. Still, what matters is long-term immunity, and by necessity that question hasn't got an answer yet. I hope Covid-19 is closer to measles than to flu in that sense.
//Symptom’s vary wildly//
erm change that to "Signs of Covid vary wildly"
and it STILL isnt quite right
the beeg three ( sorry fwee, not many numerate ABers here) are fever cough and ......
( where's the third one gone?)
arent that good - chance is 67% you will be covid +
this stat is a PPV by the way - chance that if the test/questionnaire is positive what is the chance of having the actual disease.
what people DONT understand is that having a 'rare' sign - rash - makes the test/questionnaire LESS certain. the chance of having Covid if you dont have a rash is HIGHER than the chance of fever,coughing and NO rash
coz more people with covid dont have a rash (80%) than those that do ( present in 20%)
to use Pixies phrase - incredible but true.
Note - this takes a + covid test as the gold standard - but remember some people test positive AFTER recovery and are not infectious
( and still others test positive er because they are carriers)
the lesson which medical students take years to learn - is that having a rare sign of a disease makes the diagnosis LESS likely -
fr instance - 15% of patients wiv disease X have - low platelets, and YOU have low platelets, there is an 85% chance you DONT have disease X

// Relieved to see that there's also an emerging consensus that short-term immunity, at least, is a thing -// my fave Jim
yeah some quite impt people were saying this ( no short term immunity). What like Eamonn Holmes and Amanda Holden ?
no ====people like Dr Fauci
and I have to say - I thought - well if THAT were true, then no one would get better would they? AND
if that were true why is everyone saying lets try plasma coz it works in Ebola, another disease where there is a question about immunity
anyway they have settled down to the idea that the early response IgM - may be usable.
