What is the primary hope for reopening countries during the pandemic?

• Herd immunity

• Social distancing

• Tracking technology

• Vaccination campaigns

What is a major limitation of traditional contact tracing?

• It is only effective in small communities

• It is too expensive

• People may not remember all their contacts

• It requires GPS tracking

How does mobile-based contact tracing improve upon traditional methods?

• By automatically recording contacts via phones

• By using GPS to track locations

• By using facial recognition technology

• By requiring manual input from users

What technology do Apple and Google use for their exposure notification API?

• Bluetooth

• NFC

• Wi-Fi

• Infrared

What is a key privacy concern with the Apple and Google API?
