Russia is facing a invasion.
The rodent population in Russia is at risk of doubling, as the country has excellent conditions for this. Among the reasons for this, scientists cite the access to food in garbage cans and the warm basements.
For example, only during the last year in Rostov-on-Don, the number of calls to exterminate rats has doubled.
All of these may lead to the spread of different types of diseases, including leptospirosis, salmonellosis and the Seoul virus, which is a type of antavirus.
Russian scientists express great concern.
