特朗普於周日（1月3日）發帖，炮轟美國疾控中心（CDC）。
特朗普於社交網站表示，「中國病毒」於美國的確診及死亡數字被誇大，原因CDC荒謬的計算方法，相比之下，許多國家則故意十分不準確和壓低通報的數據。
特朗普又指在存疑的時候，就將其歸類為新型冠狀病毒，他形容是假新聞。
The number of cases and deaths of the China Virus is far exaggerated in the United States because of @CDCgov’s ridiculous method of determination compared to other countries, many of whom report, purposely, very inaccurately and low. “When in doubt, call it Covid.” Fake News!
