Everything You Need to Know About Close Contact in the Era of COVID-19

What is Close Contact?

According to the Centers for Disease Control and Prevention (CDC), close contact refers to an interaction that meets the following criteria:

• Spending 15 minutes or more within 6 feet of an infected person
• Occurring within 2 days before the infected person shows symptoms or tests positive

Why Close Contact Matters

Close contact is significant because it increases the risk of SARS-CoV-2 transmission. When an infected person coughs, talks, or sneezes, virus-containing droplets are released into the air. These droplets can enter the respiratory tract of nearby individuals through inhalation, resulting in infection.

Benefits of Identifying Close Contacts

Identifying close contacts is crucial for several reasons:

• Early Detection and Isolation: Contact tracing allows health authorities to track down individuals who have had close contact with an infected person. By isolating these contacts, the spread of the virus can be contained.
• Contact Monitoring: Close contacts are advised to monitor their health for symptoms. If they develop symptoms, they can be tested promptly to confirm or rule out infection.
• Tailored Guidance: Health authorities can provide specific guidance to close contacts based on their risk level, such as advising them to quarantine or get tested.

Tips and Tricks for Identifying Close Contacts

• Recall Recent Interactions: Think back to the past 2 days and identify anyone you have spent 15 minutes or more with within 6 feet.
• Consider all Settings: This includes social gatherings, workplaces, schools, and public spaces.
• Note Down Specifics: Record the date, time, and location of each encounter.
• Use Technology: Some jurisdictions have developed apps that can help you track your contacts.
• Ask for Help: If you are uncertain about whether someone qualifies as a close contact, consult your healthcare provider or local health authority.
