When Sergei Indeik, a Russian chess official, visited Nigeria early this month as one of the leading figures in the international chess community for the World Amateur Rapid Chess Championship in Abuja, he did not know his short stay in the country would herald a chain of unforeseen fatal incidents that would culminate in his eventual death.
Indeik, a delegate of the International Chess Federation, had attended the opening ceremony of the FIDE World Amateur Rapid & Blitz Chess Championship 2026 in Abuja alongside other top officials from the Nigerian chess federation.
He was among the officials who helped organise and officiate the tournament, which was held from August 1 to 8.
However, when he left the country after the championship, he did not only leave with the memory of the country and the people he met during the championship, he left with something far more virulent, searing and malignant which will in no time turn his visit to Nigeria and his participation in the tournament into an abstract and vicarious recollection by others, while he is described in the past tense: He left with malaria.
Weeks after leaving Nigeria, FIDE announced Indeikin’s death on August 23, describing it as the result of a “sudden illness” without disclosing the specific medical condition. However, reports emerged on Wednesday that he died from a severe bout of malaria, which he had contracted during his stay in Nigeria.
Russian media outlets, citing family and parental sources, disclosed that Indeikin’s death was not unconnected to his work trip in Nigeria, where they believe he got the malaria infection that killed him.
Indeikin’s mother, Tatiana, told Russian business newspaper RBC that he had contracted a severe form of malaria while in Nigeria.
His mother said he was taken to hospital after returning to Perm, but the malaria had severely weakened his system and his condition had worsened considerably.
“It was a very rapidly progressing illness. The most severe form,” she was quoted as saying by RBC.
Russian newspaper Argumenty i Fakty, AIF, also reported that Indeikin travelled to Abuja before proceeding to Uzbekistan, where he began experiencing health problems.
His father, Alexander, told the newspaper that information provided by his son’s colleagues at FIDE suggested that malaria could have been responsible for his condition.
Indeikin later travelled through Moscow to his home city of Perm, where his health reportedly deteriorated. An ambulance was called and he was subsequently admitted to hospital, but efforts to save his life proved abortive.
The newspaper also quoted medical expert Professor Alexander Lukashev as explaining that malaria can be transmitted through the bite of an infected mosquito in Nigeria and other tropical regions.
Other Russian media organisations, including Lenta.ru, reported that Indeikin was bitten by a mosquito while attending the chess tournament in Nigeria and that the bite was suspected to have transmitted the malaria parasite.
Indeikin had been involved in FIDE events since 2021 and played a role in organising several major international competitions, including World Championship matches, World Cups, Candidates tournaments and World Rapid and Blitz Championships.
FIDE described him as an important member of its operations team who travelled extensively to help ensure that major chess events were successfully organised.
He is survived by his wife and daughter.
However, while Indeikin’s family and several Russian media reports have attributed his illness to severe malaria allegedly contracted during his trip to Nigeria, FIDE has officially cited a sudden illness for his death and has not independently confirmed malaria as the medical cause of death.
