So did he exchange bodily fluids with 12 people then?

Health officials are monitoring the condition of 12 people who were in close contact with a traveller diagnosed with monkeypox who transited through Thailand for two hours while en route to Australia.
Chakarat Pittayawonganon, director of epidemiology at the Department of Disease Control, said on Monday that the 12 people were passengers and flight attendants on the same flight as the confirmed case.
They had remained asymptomatic over the past seven days and would be monitored until day 21, the disease incubation period.
Dr Chakarat said the confirmed case had travelled from Europe and spent two hours in transit.
Those who were in close contact with the case were not at high risk because the infected passenger was asymptomatic during the transit period.
