Enterovirus A71 Meningoencephalitis Outbreak, Rostov-on-Don, Russia, 2013.

Seventy-eight cases of enterovirus infection, including 25 neuroinfections, occurred in Rostov-on-Don, Russia, during May-June 2013. The outbreak was caused by an enterovirus A type 71 (EV-A71) subgenotype C4 lineage that spread to neighboring countries from China ≈3 years earlier. Enterovirus associated neuroinfection may emerge in areas with a preceding background circulation of EV-A71 with apparently asymptomatic infection.

Probable Crimean-Congo hemorrhagic fever virus transmission occurred after aerosol-generating medical procedures in Russia: nosocomial cluster.

We report here a fatal case of laboratory confirmed Crimean-Congo hemorrhagic fever (CCHF), which caused nosocomial infection in eight health care workers (HCWs), who had provided medical care for the patient. All the HCWs survived. The report demonstrates that airborne transmission of CCHF is a real risk, at least when the CCHF patient is in a ventilator.
