Calin Georgescu, the far-right politician who shocked Romania by topping the first round of presidential elections last month, shot to prominence by campaigning online, spreading disinformation on social media.
His claims -- touching on issues from health to Ukraine to climate -- include denying the existence of Covid and alleging the Moon landing was a hoax.
Here is a look ahead of Sunday's second round of presidential elections at some of the disinformation he has spread.
"There is no Covid, no one has seen it. The only science is Jesus Christ," declared the 62-year-old former senior civil servant on the social media network YouTube on November 11.
His nationalist speeches are often tinged with mysticism.
In a 2021 video, he is seen diving into an icy lake with snow-capped mountains in the background and boasting about the strength of his "immune system" and "his faith in God".
Even before the pandemic, he criticised vaccines, calling viruses "artificially created enemies".
"The vaccine doesn't boost your immune system, it weakens it," he said.
Only 45 percent of Romania's population of 19 million is vaccinated against the coronavirus, well below the EU average of 70 percent.
More than seven million deaths have been officially recorded worldwide since the disease appeared in China at the end of 2019.
The WHO estimates the actual number to be even higher, with vaccines having saved millions of lives.
