Besmettingen is iets wat zeer zeker heel belangrijk is. Immers COVID 19 is een agressief virus dat veel schade kan aanrichten.
Mensen die besmet raken kunnen, ook al belanden ze niet in het ziekenhuis en ook al komen ze niet te overlijden, dan kan het virus een zware impact hebben, soms ook op langdurige kwalen, Long Covid

Ok, time to do a thread on long COVID. Long COVID is a *real* multi-system syndrome that occurs in those infected (far more common than in uninfected controls)- predominantly impacting the young. Let's do a deep delve into this syndrome that some in JCVI ( Joint Committee on Vaccination and Immunisation ) are in denial about!
Some statistics first :
there are several studies that now put the overall incidence of long COVID as between 10-50% of those infected, depending on symptoms studied & cohorts studied.
The ONS survey showed very clearly that 13.7% of those infected (1 in 8) developed long-term symptoms > 12 wks compared to <2% controls

'But it doesn't affect old people'...
it absolutely does! The majority of those affected are <50 yrs. And it affects children. Between 10-13% of children have symptoms for 5 wks or more, and 7-8% of children had symptoms for *12 wks or more* compared with <2% of controls.

'But it's just mild symptoms that don't matter, and most people only have 1 symptom'
Unfortunately, there's a plethora of symptoms, and many of them are very common, so many people present with a combination of symptoms. The ONS only examined 21- there are 100s of symptoms.
3
Of the ca 1 million people ( in the UK ) affected, 2/3rds said it impacted their day to day activity. And 400,000 have had persistent symptoms for more than a year.
4
These 400,000 sadly include 9000 children who have been affected for more than a year. This isn't a mild syndrome, or a short one for thousands of our young- who've been impacted due to policies where they were forced to go into unsafe environments without adequate mitigation.
5
So, to summarise, long COVID is common - even in young people with mild infection - who don't have to go into hospital. And it also affects children, and is usually multiple symptoms, that in many affect day to day lives. Let's look at other data now.
6
The cognitive symptoms (brain fog, memory loss, difficulty concentrating, sleep disturbances) tend to become prominent later in long COVID, & also last longer. These are worrying also because there are now studies showing the virus affects the brain, even in younger people.
7
There is strong evidence now that even those with mild infection can have long-term structural brain changes, including thinning of grey matter is specific brain areas related to smell, taste, memory & emotion
8
Neuro-psychiatric disease is common post-COVID even among those not hospitalised with severe infection. COVID-19 also appears to be associated with increased risk of strokes, and other neurological conditions at 6 months post infection:
