It all started with a headache…😢

Moisés Ponce Mendoza, a teenager from North Carolina, United States, arrived at the Burlington hospital on a Friday night with that single symptom.

A doctor examined him, told the family they could go home, and no one suspected that a lethal infection was already spreading inside his skull.

By the following morning, his mother had to leave work and rush with him to the University of North Carolina hospital at 7 in the morning.

That was when the diagnosis that changed everything arrived: Naegleria fowleri, the amoeba known as a “brain-eating” amoeba, had entered through his nose —probably while swimming in fresh water— and began destroying his brain tissue, causing severe inflammation and infection.

Moisés fell into a coma while doctors tried to stop damage that was already irreversible. He lost the battle on Monday, August 1.

Fewer than ten people a year contract this infection in the United States, and most do not survive more than five days after the first symptom appears.

His mother, Mónica Mendoza, described her son as a young man “full of life” 💔🕊️
