“It has been established that dissemination of SARS-CoV-2 from the systemic circulation or through the plate of the ethmoid bone (Lamina cribrosa) can lead to brain damage. A change in the sense of smell (hyposmia) in a patient at an early stage of the disease can indicate both damage to the central nervous system and edema of the mucous membrane of the nasopharynx, ”the document says.

It is noted that the main source of infection is a sick person, including those in the incubation period of the disease.

“Transmission is carried out by airborne droplets, airborne dust and contact routes,” the document emphasizes.

You can get infected when talking with an infected person at close range (less than 2 meters).

“It is known that at room temperature SARS-CoV-2 is able to maintain viability at various environmental objects for three days,” the department added.

The Russian Ministry of Health has also updated temporary guidelines for the prevention, diagnosis, and treatment of coronavirus infection. In particular, the list of possible drugs for adult use has been expanded.
