An employer should inform workers if someone they have come into contact with has tested positive for COVID-19.
The BBC reports that England has strict measures for employees in the workplace. This includes minimizing office visits by allowing staff to work from home, cleaning surfaces frequently, extra care in washing hands, putting protective screens between each staff, avoiding “hot desking”, using appropriate PPE, and ensuring that clinical extremely vulnerable workers do not attend the workplace.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
