Two strains of virus have been identified as being behind a recent mass illness in Russia's Chechen Republic.
In a statement on June 23, Russia’s consumer protection agency, Rospotrebnadzor, said forensic tests conducted in Moscow had proven the presence of adenovirus and astrovirus in springwater from a village in eastern Chechnya.
The viruses frequently cause diarrhea and were blamed for the hospitalization of 229 residents of Ishkhoi-Yurt earlier this month.
In a statement on June 4, Rospotrebnadzor's branch in Chechnya had excluded tainted water as the culprit.
All of the patients have since been discharged from hospitals.
