russia's chief state sanitary doctor Anna Popova has signed a resolution "On Additional Measures to Prevent Cholera". It focuses on additional prevention measures in the regions bordering Ukraine: Briansk, Kursk, Bielhorod, Voronezh, Rostov regions, Krasnodar Krai, as well as the occupied Crimea.

The heads of the territorial departments of the Federal Service for Supervision of Consumer Rights and Human Welfare (Rospotrebnadzor) were instructed:

to prepare laboratories for cholera research by May 15, strengthen control over trade facilities, and crowded sites to raise awareness among the population about disease prevention measures;

to ensure that medical institutions be ready to implement anti-epidemic measures and calculate the amount of needed medication by June 1.

Probably, in late May or early June, russia's leadership may resort to provocations in areas bordering Ukraine, to traditionally shift responsibility onto Kyiv, accusing Ukraine of "using biological weapons".
