The city wants entrants to fill out a questionnaire that asks whether a person has had contact with a monkeypox patient in the past 21 days, has signs of fever or swollen nodes or rash.
The World Health Organization declared monkeypox a global health emergency last week. WHO Europe has forecast just over 27,000 monkeypox cases in 88 countries by Aug. 2, up from 17,800 cases in nearly 70 countries at the latest count, according to Reuters.
Vietnam has not recorded any monkeypox infection so far.
