President Donald Trump’s 14-year-old son, Barron, tested positive for COVID-19 but exhibited no symptoms after both of his parents contracted the virus, first lady Melania Trump said on Wednesday.

“Luckily he is a strong teenager and exhibited no symptoms,”Melania Trump said in a statement.

She said she and Barron had since tested negative for the virus.

Donald Trump told a rally in Des Moines, Iowa, that Barron”is just fine now” and said it was an example of why schools should reopen.

“I don’t even think he knew he had it, because they’re young and their immune systems are strong and they fight it off,”Trump said. “Get the kids back to school,” he said.

Melania Trump said her symptoms were “minimal” and that she hoped to resume her duties as first lady “as soon as I can.”

“I experienced body aches, a cough and headaches, and felt extremely tired most of the time,” she said.

“I chose to go a more natural route in terms of medicine, opting more for vitamins and healthy food,” Melania Trump said.

Donald Trump spent three nights in a military hospital after announcing on October 2 that he and Melania had tested positive.

To treat the virus, he received an experimental dual anti-body therapy developed by Regeneron Pharmaceuticals Inc and Gilead Sciences Inc’s antiviral remdesivir, as well as the steroid dexamethasone.

“In one way I was glad the three of us went through this at the same time so we could take care of one another and spend time together,” Melania Trump said.
