What are the data protection implications of holding Covid-19 health data?

The ICO is providing new guidance to organisations regarding data protection and coronavirus, which can be accessed here: https://ico.org.uk/for-organisations/data-protection-and-coronavirus/

Information about the Covid-19 health status of individuals is special category data under the GDPR. This means it is high risk which has implications for how you use it, store it and keep it secure.

You will already hold health data about your employees as this is necessary to provide a safe, accessible place to work and to make reasonable adjustments to the workplace. You now need to make sure that the information you gather about your employees, visitors to your sites, customers and suppliers about Covid-19 is processed in accordance with data protection laws.
