Their findings reveal that the inhaled infectious dose of mpox is at least 100 times lower than that of SARS-CoV-2 and smallpox, making efficient respiratory aerosol transmission highly unlikely ...

This subset includes the smallpox, vaccinia and cowpox viruses. While an animal reservoir for monkeypox virus is unknown, African rodents are suspected to play a part in transmission.
