Donald Trump's optimistic and often misleading statements about his administration's response to the coronavirus pandemic stand in sharp contrast to the measures that first responders are seeing in hospitals across the US.

While he's now under scrutiny for overplaying the assistance and relief that the federal government plans to make available, the president's early efforts to diminish the viral outbreak came as confirmed cases of Covid-19 continued to surge.

His statements were met by waves of criticism from his political rivals and public health officials, including members of his own administration leading the response.

A Reddit user matched the president's public statements over the last several weeks to a graph that charts the growing number of coronavirus cases in the US up to this week, showing how the outbreak's impact contradicted the president's own confident claims about his administration's response.

Andy Balk, who made the image, said it appeared that the president has been "downplaying what was a real threat."

He told The Independent: "But could it be that he was just trying to stop people from overreacting to something that he had control over? How did the data that he had at the time inform his public statements? I made this plot to answer these questions."

"It is clear that he was downplaying something that he should have known was going to be devastating in the US. The fact that we had plenty of data from other countries makes this case even stronger."

The graph superimposes some of the president's statements over a graph of the number of cases from January through 18 March.

After the first cases appeared in Washington in January, the president insisted that the US had "pretty much shut [coronavirus] down" and said "it's going to be fine".

Nearly a month later, he claimed that cases were "going substantially down, not up" just days before he number of confirmed infections reached 1,000.

In late February, he claimed the virus "would disappear" as US infections reached 4,000, then slammed reports of the outbreak as part of a "hoax".
