People who have undergone covid-19 report brain and respiratory problems more often than those who have not had diseases, according to FHI.
The National Institute of Public Health (NIPH) has published the results of a study about late-onset coronary heart disease among unvaccinated adult participants in the Norwegian Mother, Father and Child Survey (MoBa).
The data show that people who have undergone covid-19 disease experience an over-frequency of symptoms twelve months later, the institute writes.
In particular, two main groups of symptoms were reported:
- Some experienced symptoms related to the brain, for example in the form of brain fog, poorer memory or dizziness, and in addition palpitations and fatigue.
- Others reported respiratory symptoms, such as coughing and shortness of breath.
– The findings may indicate that this is about a number of different ailments that probably can not accumulate under one syndrome, because they behave quite differently in different people, says project manager and doctor Lill Trogstad at the National Institute of Public Health.
She emphasizes that the findings must be confirmed in other studies before one knows how representative they are.
More common in women
The purpose of the study was to investigate whether there was an over-frequency of 22 different symptoms among unvaccinated adults who have undergone covid-19.
- Among those who have not had the disease, 21 percent reported that they had at least one of the 22 symptoms in the last six months.
- Among those who underwent covid-19, more than half reported −56 percent – having had at least one of the symptoms.
17.4 per cent of those infected report that they experienced fatigue twelve months after the infection. The figure for those who were not infected was 3.8 per cent.
18.2 percent of those infected reported reduced memory twelve months after infection. The figure for those who were not infected was 3.6 percent.
FHI writes that the ailments were more common in women than in men, and were also more common among those who had been quite or very ill compared with those who answered that they had hardly been ill.
The study is based on 70,000 adults between the ages of 30 and 65, whom FHI has followed through the pandemic by asking them to answer various questions every 14 days.
