Table 6.

Classification of Contact Types and Approach.

Type of Contact	Approach
1. Close contact with a probable/confirmed case of COVID-19 with adequate use of personal protective equipment	Continue with normal healthcare activity and carry out passive surveillance for the appearance of symptoms.
2. Close contact with probable/confirmed case of COVID-19 without personal protective equipment	a. If it is considered a high-risk exposure: withdraw from healthcare activities for 14 days or consider relocation to another area of the hospital. People must be reachable throughout the follow-up period. In general, social activities and non-essential travel should be limited.
	b. If it is considered a low-risk exposure: continue with normal healthcare activity.
	In both situations, vigilance should be active.
3. Casual contact with probable/confirmed COVID-19 case without personal protective equipment	Continue with normal healthcare activities with passive vigilance of the appearance of symptoms.
4. International medical activities in areas with sustained local transmission of COVID-19	Assess contact type (Occupational Risk Prevention Department of the organization involved as well as the Public Health department of the autonomous community) and follow points 1–3.
What is considered close contact? - Any person who has provided care to a probable or confirmed case while presenting symptoms: health workers who have not used adequate protection measures, family members or people who have other similar physical contact. - Any person who has been in the same place as a probable or confirmed case while the case presented symptoms, at a distance of less than 2 m (e.g., cohabitating, visits)
