When investigating close contacts, the investigators should wear disposable work caps, medical surgical masks, work clothes, and disposable gloves, keeping a distance of more than 1 meter from the target of investigation.

When investigating suspect cases, confirmed cases and asymptomatic infected persons, it is recommended to wear work clothes, disposable work caps, disposable gloves, protective clothing, KN95

/ N95 or above particulate protective masks or medical protective masks, protective face shields or goggles, work shoes or rubber boots, waterproof boot covers, etc.
