While COVID-19 patients had a higher risk of venous thromboembolic disease compared to influenza and sepsis patients, the risk of other adverse outcomes was comparable.

"It does take the immune system a while to build up antibodies and recover," said Madeline King-Patel, PharmD, BCIDP, "So you don't want to give the vaccines too close to each other, or you're not going to get the full benefits."

This study determined the efficacy of face masks at reducing exhaled particles in children, as well as whether the type of activity affected the concentration and size of particles.

People with COVID-19 who were hospitalized had a slightly higher rate of death than those with influenza. However, there were considerably more severe COVID-19 cases than the flu, leading to a much higher number of overall deaths associated with SARS-CoV-2.
