In 2001, Elon Musk nearly died of malaria.
In late 2000, after Peter Thiel and the board pushed him out as PayPal CEO, Elon took his first real weeklong break from work. He went to Brazil to see a cousin, then to South Africa for a family wedding. After time with family in Pretoria, he and then-wife Justine went to a game reserve.
He got back to Palo Alto in January 2001 and started feeling bad. At Stanford's ER and Sequoia Hospital, he received a wrong diagnosis while his symptoms continued to worsen.
A doctor from San Jose General who actually knew tropical disease walked past the Elon bed and recognized Plasmodium falciparum malaria - the strain that can wreck the brain, lungs, and blood in a day once it turns severe. After symptoms get that bad, patients often have about a day before the parasite is effectively untreatable.
Elon recalled: “I was first misdiagnosed at Stanford Hospital with viral meningitis, then again misdiagnosed at Sequoia. A visiting doc from San Jose General saw my charts & sent me to ICU immediately. I was ~36 hours from being unrecoverable.”
