When a cheap steroid has a big effect on COVID-19, there's a real danger that too many people will take it. Listen to DW's science podcast for a different angle on the coronavirus — five minutes every day from Germany.
Six months have passed since SARS-CoV-2 became known worldwide. Since then, researchers have found out much about the virus and made progress in combating it. Here are the most important points.
239 researchers called for an update of the coronavirus guidelines by the WHO, as transmission via ultrafine suspended matter in the air was not sufficiently taken into account. Now the WHO also sees the danger.
A cheap, widely available steroid was shown to help severely ill coronavirus patients, Oxford University researchers said. The UK is making the drug, dexamethasone, standard for treating COVID-19.
A drug shown to lower mortality rates among seriously ill COVID-19 patients in Britain is being hailed as a "breakthrough" by the World Health Organization. However, further research must be done.
