Why are these three presidents downplaying coronavirus warnings?

Mexico City (CNN)Brazilians have been tricked by the media over a "little flu," according to president Jair Bolsonaro. Families should still go out to eat despite coronavirus fears, says Mexico's president Andres Manuél Lopez Obrador. And Nicaragua's leader Daniel Ortega has all but disappeared, while political marches and rallies continue.

As global leaders race to contain the brutal threat of a growing pandemic, a triumvirate of denial has emerged in Latin America, with the leaders of Brazil, Mexico and Nicaragua downplaying the danger of a looming outbreak.

    In the beginning, Obrador dismissed the threat posed by the novel coronavirus and "this idea that you can't hug," telling reporters on March 4, "You have to hug. Nothing happens." Ten days later, he posted a video of himself surrounded by supporters, hugging them and kissing a child. Two days after that, he held up two amulets and told reporters they would protect him from the virus.
    As confirmed cases have surged in recent days, AMLO, as the president is often called, has shown more concern, encouraging people to stay home. He said his cabinet will be working on ways to help vulnerable populations, providing relief to small businesses and banning gatherings of 100 people or more.

"We do nothing good and we don't help if we're paralyzed, if we act in an exaggerated way," he said in the video. "Let's continue living life normally."

"Men can be more detached but daughters are always tending to their mothers, their fathers. So, men and women, take care of our elderly," he concluded, going on to say multiple times that Mexico is prepared to handle the crisis.
    To date, Mexico has registered 405 confirmed cases. An additional 1,219 others are suspected of having the virus and five people have died so far. Experts have told CNN given the paltry level of testing in the country, the true count could be much higher.
    Two doctors who are on the frontline of the fight warn that Mexico could be a disaster waiting to happen. "I do not think Mexico is prepared for this," said one veteran physician at a leading hospital in Mexico City, who asked to remain anonymous because he was not authorized to speak to media. "We aren't testing enough because there aren't enough tests, and we do not remotely have enough beds, enough ventilators, not even enough facemasks to treat this epidemic."
