“Measures recommended by the IHR Committee (of which Russia is a member) include increased surveillance, hygiene measures, isolation of sick people and those who have been in contact with them ... Mass vaccination is not recommended,” she told RIA Novosti.

Controlling outbreaks is primarily dependent on public health measures, she said.

The World Health Organization (WHO) Emergency Committee had previously recognized the emergency nature of the monkeypox outbreak, but did not agree that it was an emergency of international concern.
