lit a candle 4h agoThis one hit different because I follow science news anyhow, not just Nigeria matters, and I remember reading in 2020 how a small country of three million people built their own covid test when bigger countries were still struggling with supply chains. Uruguay. I had to look it up on the map. The man led that work, Moratorio, and I kept thinking why can't our own universities get that kind of support, that kind of trust from government to just go and solve the problem. He was only 44. Brain tumour took him, grade 4 they said, same thing that takes so many good people before their time. I don't know him from anywhere, never been to Uruguay, but I followed his case when he was fighting the ministry there for his medicine, that part stayed with me more than the covid story sef. May his soul rest in perfect peace. Edit, I just saw he has a daughter that was born while he was sick, God help that family.

Gonzalo Moratorio was a Uruguayan virologist who became one of the best known scientists in Latin America during the COVID-19 pandemic, when he helped lead the development of Uruguay's own diagnostic test for the coronavirus. He headed the Laboratory of Experimental Virus Evolution at the Institut Pasteur de Montevideo and was an associate professor in the Faculty of Sciences of the University of the Republic. He died in Montevideo on 5 November 2026, aged 44, after more than a year of living with an aggressive brain tumour.
Born in Montevideo on 8 October 1982, he studied biological sciences and then took a master's degree at the Faculty of Sciences. His doctorate, completed in 2012 through the PEDECIBA programme with the Institut Pasteur de Montevideo, included research at the University of California, San Francisco. From 2012 to 2018 he was a postdoctoral researcher in molecular virology at the Institut Pasteur in Paris, studying how viruses mutate and adapt, before returning home to set up his own laboratory.
When the pandemic reached Uruguay in March 2020, Moratorio and his colleague Pilar Moreno, working with the University of the Republic and state agencies, produced a national test kit that let the country test widely and cheaply. Uruguay kept infections and deaths low for much of 2020, and the journal Nature named him one of its ten people who mattered in science that year, the only Latin American on the list. He also served on the government's Honorary Scientific Advisory Group, the GACH.
He became a familiar public face of science, co-hosting the television programme Espacio Ciencia TV and even appearing as a masked contestant on Who is the Mask? in 2023. He co-authored more than 50 scientific papers, held patents on synthetic RNA viruses as possible vaccines, and co-founded the startup Guska with Pilar Moreno.
In June 2025 he announced that he had been diagnosed with a grade 4 astrocytoma, a highly aggressive brain tumour. He was treated at the Hospital Sírio-Libanês in Brazil and shared his progress openly. Guska turned its research towards brain tumour therapies. His daughter, Abril, was born at the end of 2025. When the tumour returned in 2026 he went to court to obtain an expensive immunotherapy from the Ministry of Public Health, and won at first instance and on appeal. In May 2026 Parliament honoured him as one of the Contemporary Heroes of the Bicentennial.
President Yamandú Orsi said Uruguay would be eternally grateful to him for helping the country understand and face an unknown pandemic. Tributes came from across the political spectrum, from the Institut Pasteur, the university and the ministry, and from his beloved Club Nacional. He was survived by his wife, Natalia Ibáñez, and their daughter.
