Covid-19 võib päevade jooksul levida ajju ja südamesse. Üldse on see võimeline nakatama peaaegu kõiki organisüsteeme, millest tulenebki pikaajalise põdemise ja pikaajaliste järelnähtude probleem. Praegu pole võimalik öelda, milliseks krooniliste haigete hulk tulevikus kujuneb ning mida see hõlmab - vara algavaid südamehaigusi või dementsust või midagi muud. "Nature's" selle kohta uus artikkel:
The coronavirus that causes COVID-19 can spread to the heart and brain within days of infection and can survive for months in organs, according to a new study by the National Institutes of Health.
The virus can spread to almost every organ system in the body, which could contribute to the ongoing symptoms seen in "long COVID" patients, the study authors wrote. The study is considered one of the most comprehensive reviews of how the virus replicates in human cells and persists in the human body. It is under review for publication in the journal Nature.
The NIH researchers sampled and analyzed tissues from autopsies on 44 patients who died after contracting the coronavirus during the first year of the pandemic. They found persistent virus particles in multiple parts of the body, including the heart and brain, for as long as 230 days after symptoms began. This could represent infection with defective virus particles, they said, which has also been seen in persistent infections among measles patients.
"We don't yet know what burden of chronic illness will result in years to come," Raina MacIntyre, PhD, a professor of global biosecurity at the University of New South Wales, told Bloomberg News. "Will we see young-onset cardiac failure in survivors or early-onset dementia?" she said. "These are unanswered questions which call for a precautionary public health approach to mitigation of the spread of this virus."

https://www.ons.gov.uk/peoplepopulation ... ctober2021Symptoms were present in 385 (89%) participants at diagnosis and 81 (19%) were initially hospitalized. At six to eight months, 111 (26%) reported not having fully recovered. 233 (55%) participants reported symptoms of fatigue, 96 (25%) had at least grade 1 dyspnea, and 111 (26%) had DASS-21 scores indicating symptoms of depression. 170 (40%) participants reported at least one general practitioner visit related to COVID-19 after acute illness, and 10% (8/81) of initially hospitalized individuals were rehospitalized. Individuals that have not fully recovered or suffer from fatigue, dyspnea or depression were more likely to have further healthcare contacts. However, a third of individuals (37/111) that have not fully recovered did not seek further care.

Euroopa standard on siiski FFP2.
