Russian Chess Official Dies of Severe Malaria After Nigeria Trip: Who Was Sergei Indeikin?
A 36-year-old Russian chess official has died after reportedly contracting a severe form of malaria following a work trip to Abuja.
Sergei Indeikin (also spelled Sergey Indeykin), operational manager and delegate of the International Chess Federation (FIDE), passed away after falling ill shortly after leaving Nigeria. The story has drawn attention in both chess circles and Nigerian news because the infection is believed to have been picked up during the FIDE World Amateur Rapid and Blitz Chess Championships held in Abuja from 1 to 8 August 2026.
Who Was Sergei Indeikin?
Indeikin joined FIDE events in 2021 and quickly became a key behind-the-scenes figure.
He worked on some of the federation’s biggest tournaments, including World Championship matches, World Cups, Candidates Tournaments, and World Rapid and Blitz Championships. Colleagues described him as reliable, professional and generous. FIDE noted that he supported an orphanage and regularly brought chess souvenirs and small gifts for the children from his travels.
He is survived by his wife and young daughter.
The Nigeria Trip and Timeline
Indeikin travelled to Abuja as an official for the FIDE World Amateur Rapid and Blitz Chess Championships. FIDE’s own coverage of the event listed him among the organisers on the ground.
After the tournament ended on 8 August, he travelled to Uzbekistan for further work. That is when he began feeling unwell. He later returned to Russia via Moscow and went to his hometown of Perm. His condition deteriorated rapidly. Relatives called an ambulance and he was admitted to hospital, but doctors were unable to save him.
FIDE announced his death on 23 August, calling it the result of a “sudden illness.” The federation did not name the specific cause.
What Family and Russian Media Said
Russian outlets including RBC, Argumenty i Fakty (AIF) and Lenta.ru later reported that relatives believe he contracted a severe form of malaria in Nigeria.
His mother, Tatiana, said the illness progressed very quickly and was “the most severe form.” She told reporters he was already critically ill by the time he reached hospital in Perm. His father, Alexander, said colleagues described symptoms consistent with malaria and that the infection was likely linked to a mosquito bite during the Abuja trip.
Medical expert Professor Alexander Lukashev, quoted by AIF, noted that malaria is transmitted by infected mosquitoes in Nigeria and other tropical regions.
Official Position vs Reports
FIDE has not publicly confirmed malaria as the official cause of death. The federation’s statement remains limited to “sudden illness.” The malaria link comes from family members and Russian media reports citing them. A final medical conclusion would typically come from autopsy or official records, which have not been released in detail.
Why the Story Is Circulating
Nigeria carries one of the world’s highest malaria burdens. For many visitors from non-endemic countries, the disease can progress far more aggressively than it does for people who have grown up with it. The combination of a young international official, a high-profile chess event in Abuja, and a rapid fatal illness has made the case widely reported.

For now, the verified facts are these: Sergei Indeikin, 36, FIDE operational manager, died after falling ill following the Abuja chess championships, with his family and multiple Russian reports attributing the death to severe malaria contracted in Nigeria.
