Sergei Indeikin, a Russian operational manager and delegate for the International Chess Federation (FIDE), has died at the age of 36 after developing a severe form of malaria following a work trip to Nigeria, according to his family and Russian media reports.
Indeikin travelled to Abuja in early August for the FIDE World Amateur Rapid and Blitz Chess Championships, held from August 1 to 8. He was listed among the officials overseeing the event. After the tournament, he travelled to Uzbekistan, where he began feeling unwell, before returning to his hometown of Perm in Russia.
His condition deteriorated rapidly. He was admitted to hospital in Perm, but doctors were unable to save him. He died on or around August 23.
FIDE announced his death on its official social media channels, describing it as the result of a “sudden illness” without specifying the medical cause. In its statement, the federation said: “We are deeply saddened by the passing of our colleague Sergei Indeikin, FIDE Operational Manager, following a sudden illness.” It praised his work since 2021 on major events including World Championship matches, World Cups, Candidates Tournaments, and World Rapid and Blitz Championships, noting that he travelled extensively to ensure events ran professionally.
Russian media, including Argumenty i Fakty, Izvestia, RBC and Lenta.ru, reported that relatives attributed the death to severe malaria contracted during the Nigeria trip, likely from a mosquito bite. Indeikin’s mother, Tatiana, told reporters the illness was “very rapidly progressing” and “the most severe form,” and that by the time he reached hospital in Perm it was too late. His father, Alexander, said colleagues described symptoms consistent with malaria and that the family believed he had been bitten by an infected mosquito in Nigeria.
Medical experts quoted in Russian outlets noted that malaria is transmitted by infected mosquitoes in tropical regions such as Nigeria and that tropical malaria can be fatal if not treated promptly, though survival rates are high with early diagnosis and proper treatment.
Indeikin had also worked as a basketball agent. He is survived by his wife and young daughter. FIDE highlighted his generosity outside work, including support for an orphanage to which he brought chess souvenirs and gifts from his travels.
While family accounts and Russian media have linked the death to malaria acquired in Nigeria, FIDE has not publicly confirmed the specific cause beyond a sudden illness.
