Which of the following illnesses must an employee notify their manager about if diagnosed?

When it comes to workplace health and safety, certain illnesses carry a higher risk of transmission and can have severe implications for both the individual and their colleagues. Typhoid fever is classified as a serious bacterial infection that can significantly impact public health, especially in environments where food handling and hygiene practices are critical.

If an employee is diagnosed with typhoid fever, it is essential for them to notify their manager due to the serious nature of this illness and its potential for transmission to others in the workplace. This notification allows for appropriate measures to be taken, such as ensuring that anyone who may have been in contact with the affected employee can be monitored or provided with necessary preventive care.

In contrast, conditions such as the common cold, a headache, or seasonal allergies generally do not pose the same level of risk for contagion or severe health implications for the workplace. While they can affect an employee's individual well-being and productivity, they do not require the same level of notification or action as a serious communicable disease like typhoid fever. Thus, the emphasis on notifying management in the case of typhoid fever is rooted in its potential consequences for collective health and safety in the workplace.
