The purpose is to learn more about the course of the disease, why the disease strikes so hard on certain individuals and to map immunity.

The study is a collaboration between researchers in infection, virology, pulmonary medicine, pediatrics and molecular biology.

- For natural reasons, there is extremely little data from people with covid-19 infection.

The more we know about the meeting between virus and patient, the better we can predict the right treatment and medication, says Alicia Edin, ST doctor and one of the researchers in the study.

A total of 340 people are included in the study at the Clinical Research Center in Umeå at Norrland University Hospital.

In addition to measuring lung capacity, blood pressure and oxygenation in the blood, the test group must also do squats to check their strength.

By comparing different measurement results in whole and a half years, which are taken even more carefully in the beginning, a lot of information is built.
