Brazil's President Jair Bolsonaro on Thursday said he might have "mold" in his lungs after spending weeks in isolation after catching coronavirus disease 2019 (COVID-19).

Bolsonaro appeared in public through a Facebook live video, the first one he had since he recovered from COVID-19. In it, he said he had just taken a blood exam.

He had been in self-isolation in his house for about 20 days and said he had caught "other things," while recovering from coronavirus. "I've caught mold, mold in my lungs. It must be that," Bolsonaro said.

Bolsonaro tested positive for COVID-19 three times since July 7. He announced that he was free of the virus on July 25 through a tweet, the CNN noted.

He said he felt "a bit weak" and there was also "a bit of an infection" found in him. For now, the Brazilian president said he is taking antibiotics.

A statement from the president's press office confirmed that his wife, Michelle Bolsonaro, also tested positive for COVID-19.

The statement said the first lady "is in good health and will follow all established protocols." She was last seen in public on Wednesday afternoon, when she went to an official event in Brazil with her husband. The office also said she's with the president's medical team, the CTV News said.

Bolsonaro, in his Thursday address, thanked God and hydroxychloroquine for his health.

"I'm healed from Covid. I have antibodies, no problems. In my particular case, I first thank God, and secondly, the medication prescribed by the presidential doctor: hydroxychloroquine," he said.

After taking the drug, he claimed that he was "already okay" the next day. If that was a coincidence or not, he did not know, he added.

Ineffective Drug

Numerous studies have shown that the drug, which he claimed helped in his recovery, was not a helpful cure against COVID-19. Some studies have also seen the drug as harmful.

Other than Bolsonaro, hydroxychloroquine is also supported by President Donald Trump.

Brazil is right next to United States in terms of numbers of coronavirus deaths and infections, but Bolsonaro had chosen to downplay the coronavirus for a span of months. He often goes out in public or at rallies without a face mask. On some occasions, he had even hugged his supporters.

Bolsonaro made an appearance on horseback during a visit to Piaui State Thursday. There, he was greeted by supporters and some of them were not wearing masks.

In his official Facebook page, the video showed him on a horse, given to him as he arrived at Sao Raimundo Notato airport. He wore a mask at first, but removed it in the midst of celebrating with supporters.

The visit was meant to improve the president's relations with regional heads and to inaugurate a water system in Campo Alegre de Lourdes, a small town in the northeast state of Bahia.

Science Minister Tests Positive for COVID-19

Other than the president and first lady, there have also been other officials in Brazil, who tested positive for COVID-19, the Reuters reported.

Science and Technology Minister Marcos Pontes was one of them. This makes him the fifth cabinet minister to be publicly diagnosed with COVID-19.
