Hanta Virus – Russia
58 reported cases as of early 2021 (specific date not provided in source); two of the cases were children. Cases were registered in 14 districts and 3 cities within the Udmurt Republic. No fatalities reported.
Incidence rate to-date as follows: 1) Alnash District exceeded average repluican level by 15.8 times; 2) Kiznersky District exceeded average republican level by 9.2 times; 3) Sharkansky, Uvinsky, Grakhovsky exceeded average republican level by 3-5 times
Route of disease transmission was via air-dust, according to the source. It is suspected that the mode of transmission originated from the aerosolized waste/fluids/habitat of rodents.
Rodent extermination (deratization) efforts continue to be performed throughout all districts of the Udmurt Republic. Specific location / physical origin of outbreak not identified in this source.

Exposure to Hantaviruses can cause a rare but often fatal disease called Hantavirus pulmonary syndrome (HPS) or a hemorrhagic fever, which can progress rapidly into serious complications.
Humans are most often exposed by breathing in air particles contaminated by deer mouse saliva, urine, or feces containing infectious Hantaviruses.
Caution must be used when opening cabins, sheds or garages after a period of time. Floor surfaces may be contaminated and are best disinfected with a 10% bleach solution to avoid raising contaminated dust.
The natural reservoir of Hantavirus is rodents, although infected with the virus it does not cause disease in them. Humans may become infected with Hantaviruses through contact with rodent urine, saliva, or feces. Some strains cause potentially fatal diseases in humans, such as Hantavirus hemorrhagic fever or Hantavirus pulmonary syndrome. Human infections of Hantaviruses have almost entirely been linked to human contact with rodent excrement; however, in 2005 and 2019, human-to-human transmission of the Andes virus was reported in South America. Hantavirus infections have been reported from all continents except Australia.
Hantavirus is named for the Hantan River area in South Korea where an early outbreak was observed.
