So far I have seen claims of her contracting it doing fieldwork in Buryatia only in telegram groups with no sources. The head of Buryatia Tsydenov released a statement saying she had not been there and that the republic doesn't have animals that carry it.
Of course, Russias pure animals have no stinky diseases, and we can trust their officials every word they say. Also, Russia doesn’t have any gays, because that is a “western disease”.
