The drug Remdesivir was initially thought against ebola, but has worked against other coronaviruses, such as SARS and MERS.

- There are a number of investigations in the world and our hope is that we will soon be able to start such an investigation in Sweden as well, says Anders Sönnerborg, professor and chief physician, at the Karolinska Institute.

Malarial drugs are being investigated

The anti-malarial drug Chloroquine also appears to have an effect on covid-19. Results from treatment with the malarial drug have been reported from China, Australia and France, among others.

In addition, two HIV drugs and hundreds of other approved drugs are being studied to see which can have an effect on covid-19.

- When you put in, we start to treat with chloroquine phosphate, says Anders Sönnerborg.
