Aug. 13 (UPI) -- The director of the Centers for Disease Control and Prevention told employees about the dangers of misinformation, four days after a suspected gunman shot at the agency's headquarters in Atlanta, claiming the COVID-19 vaccine made him sick.

On Tuesday, Susan Monarez met with staffers virtually and then sent a note to all 10,000 employees nationwide, obtained by ABC News. Staffers at the headquarters have been working remotely since the attack on Friday.

"The dangers of misinformation and its promulgation has now led to deadly consequences," she wrote. "I will work to restore trust in public health to those who have lost it -- through science, evidence and clarity of purpose. I will need your help."

The comments were slightly different than those during her staff meeting in which she said: "Public health should never be under attack. We know that misinformation can be dangerous."

She said the health agency can rebuild trust with "rational evidence-based discourse" with "compassion and understanding."
