US President Donald Trump who was shifted to a military hospital after testing positive for COVID-19, has said that he has learned a lot about the novel virus.

Trump has consistently downplayed the coronavirus pandemic and rarely wore a mask before his diagnosis. Trump in a video posted on his official Twitter handle said that it has been an interesting journey and he has learned a lot about coronavirus, 'by really going to school, the real school'.

"We’re going to pay a little surprise to some of the great patriots that we have out on the street." The president was later driven past his supporters outside the hospital.

However, many doctors have criticized the drive-by saying that staff who traveled with Trump could have been exposed to the virus.

Dr James Phillips, Chief of Disaster Medicine said that every single person in the vehicle during the completely 'unnecessary Presidential drive-by' now has to be quarantined for 14 days.

On Sunday, Trump's doctors revealed that the president was given steroid dexamethasone after oxygen level drops on Friday and Saturday. The drug is used in severe cases of COVID-19 cases.
