Long flu: According to a study, the flu can also have serious long-term consequences

Not only corona infections, but also influenza, can have serious long-term consequences in hospitalized patients. This is what emerges from a study carried out by American researchers led by the American doctor and clinical epidemiologist Ziyad Al-Aly in the specialized journal Lancet infectious diseases have published. Thus, the risk of certain serious health problems increases crown as well as with influenza after the acute phase, i.e. 30 days after the start of the infection.

The researchers observed and compared the development of patients admitted to hospital due to corona or flu over a period of 18 months. To do this, they examined the cases of more than 81,000 corona patients and almost 11,000 flu patients, all treated in hospital over different periods.

“An important lesson we learned from Sars-CoV-2 is that an infection initially thought to cause only short-term illness can also lead to chronic disease,” Al-Aly said. The term Long Flu for persistent health problems after the flu has long been circulating among virologists. Al-Aly’s research group has now highlighted this in the study.

As a result, the risk of serious long-term consequences after a coronary infection was higher than after the flu, and the risk of death was 51% higher. The number of years of healthy life lost made a smaller difference: for flu patients it was 2.4 years per person, for those with corona it was 2.9 years.

Overall, the risk for corona patients was higher than for people with flu in nine out of ten organ systems examined; people with the flu only had a higher risk of negative consequences in the lungs. The question of how often was not the focus of the study Long Covid or long-term flu occur in hospitalized patients.
