Facts about Covid-19 from swprs.org:
Fully referenced facts about Covid-19, provided by experts in the field, to help our readers make a realistic risk assessment. (Regular updates below)
According to the latest immunological studies, the overall lethality of Covid-19 (IFR) is about 0.1% to 0.3% and thus in the range of a severe influenza (flu).
For people at high risk or high exposure (including health care workers), early or prophylactic treatment is essential to prevent progression of the disease.
In countries like the US, the UK, and also Sweden (without a lockdown), overall mortality since the beginning of the year is in the range of a strong influenza season; in countries like Germany and Switzerland, overall mortality so far is in the range of a mild influenza season.
In most places, the risk of death for the general population of school and working age is in the range of a daily car ride to work. The risk was initially overestimated because many people with only mild or no symptoms were not taken into account.
Up to 80% of all test-positive persons remain symptom-free. Even among 70-79 year olds, about 60% remain symptom-free. About 95% of all people develop at most moderate symptoms.
Up to 60% of all persons may already have a certain cellular background immunity to the new coronavirus due to contact with previous coronaviruses (i.e. cold viruses). The initial assumption that there was no immunity against the new coronavirus was not correct.
The median age of the deceased in most countries (including Italy) is over 80 years (e.g. 86 years in Sweden) and only about 4% of the deceased had no serious preconditions. The age and risk profile of deaths thus essentially corresponds to normal mortality.
In many countries, up to two thirds of all extra deaths occurred in nursing homes, which do not benefit from a general lockdown. Moreover, in many cases it is not clear whether these people really died from Covid-19 or from weeks of extreme stress and isolation.
Up to 30% of all additional deaths may have been caused not by Covid-19, but by the effects of the lockdown, panic and fear. For example, the treatment of heart attacks and strokes decreased by up to 60% because many patients no longer dared to go to hospital.
Even in so-called Covid-19 deaths it is often not clear whether they died from or with coronavirus (i.e. from underlying diseases) or if they were counted as presumed cases and not tested at all. However, official figures usually do not reflect this distinction.
Many media reports of young and healthy people dying from Covid-19 turned out to be false: many of these young people either did not die from Covid-19, they had already been seriously ill (e.g. from undiagnosed leukaemia), or they were in fact 109 instead of 9 years old. The claimed increase in Kawasaki disease in children also turned out to be exaggerated.
Most Covid-19 symptoms can also be caused by severe influenza (including pneumonia, thrombosis and the temporary loss of the sense of smell), but with severe Covid-19 these symptoms are indeed more frequent and more pronounced.
Strong increases in regional mortality can occur if there is a collapse in the care of the elderly and sick as a result of infection or panic, or if there are additional risk factors such as severe air pollution. Questionable regulations for dealing with the deceased sometimes led to additional bottlenecks in funeral or cremation services.
