No evidence shows Trump had any symptoms of illness until October 1. It takes 5 to 6 days for COVID-19 symptoms to show up.
There are unclear agitations that the virus was spread from the Rose Garden ceremony held on September 26. It was attended by a crowd of about 200 people and media reporters on the White House lawn. Along with Trump and his wife, at least seven other people who attended this event have tested positive - although it's unknown where they caught the virus. There were other positive cases discovered from other events also. The administration says a White House medical team is still tracing contacts.
The World Health Organization says it commonly takes around five to six days for symptoms to start after contracting the virus. However, no evidence shows Trump had any symptoms of COVID-19 before October 1. Navy Commander Dr. Sean Conley said Trump showed some common signs of COVID-19 on October 1: a mild cough, stuffy nose, and fatigue. This claim is baseless as no one can predict this disease.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
