Long COVID was defined arsenic a information wherever symptoms that past for oregon statesman astatine slightest 4 weeks aft a COVID diagnosis.
Compared to kids with nary past of a COVID-19 diagnosis, the agelong COVID-19 radical was:
- 101% much apt to person an acute pulmonary embolism (blood clot successful the lung)
- 99% much apt to person myocarditis (heart musculus inflammation) oregon cardiomyopathy (when the bosom is weakened and has a hard clip pumping blood)
- 87% much apt to person a venous thromboembolic lawsuit (blood clot successful a vein)
- 32% much apt to person acute and unspecified renal nonaccomplishment (when the kidneys can’t filter discarded from your blood)
- 23% much apt to person type 1 diabetes

MIS-C is multisystem inflammatory syndrome successful children, a information wherever galore parts of the assemblage go inflamed, that has been linked to COVID-19.
"The connection that we should instrumentality distant from this is that we should beryllium precise keen connected each the methods of prevention for COVID, particularly the vaccine," says Berger, who is besides main of cardiology successful the Department of Pediatrics astatine Northwestern University Feinberg School of Medicine successful Chicago.

How bash you specify brain fog?
Katona and colleagues are studying agelong COVID involution among students astatine UCLA to reply immoderate of these questions, including the incidence and effect of aboriginal intervention.
The survey had "at slightest 7 limitations," the researchers noted. Among them was the usage of aesculapian claims information that noted agelong COVID outcomes but not however terrible they were; immoderate radical successful the nary COVID radical mightiness person had the unwellness but not been diagnosed; and the researchers did not set for vaccination status.
Poland notes that the survey was done during surges successful COVID variants including Delta and Omicron. In different words, immoderate agelong COVID effects linked to much caller variants similar BA.5 oregon BA.2.75 are unknown.
