Delta variant to make up 90% of EU Covid cases by end of August

The report also found that those who have received just one dose of vaccine are less well protected from the Delta variant than against other variants.

The European Centre for Disease Control (ECDC) says the Delta variant will represent 90% of all Covid cases in the EU by the end of August.

According to the ECDC's threat assessment, the Delta variant - first detected in India - is 40-60% more transmissible than the Alpha (B117) strain and may increase the risk of hospitalisation.
