Experts investigated the interaction of coronavirus with red blood cells in the blood of infected patients.

Disease susceptibility often depended on how well the virus binds to the cells.

Researchers found the same pattern when studying the SARS-CoV virus that caused the outbreak of SARS in 2002-2003.
