Flu, like many viral diseases that affect the upper respiratory tract, can be transmitted through large droplet spread; contact, either direct or indirect, with respiratory secretions; through droplet nuclei, i.e. airborne spread from sneezing, coughing and even talking.

Unlike SARS where a person is infectious after the onset of symptoms, influenza cases can be contagious one day before the onset of symptoms. This “silent transmission” characteristic of the influenza infection does reduce the effectiveness of some of the measures listed, nevertheless, they are still useful to screen out those who are obviously ill and will reduce the probability of infection. Additionally, some viruses can survive for 24-48 hours on nonporous surfaces.

In a pandemic, most organizations and workplaces should be able to maintain 80% staff availability. An effective business continuity plan and workplace infection control guidelines provided by MOH will improve this. Offices and workplaces can adopt the following measures to reduce the probability of transmission in the workplace.

1. Individuals should practice good personal hygiene.
2. Staff and visitors need to be educated on the transmission mode of the disease and the steps that can be taken to prevent transmission.
3. Implement temperature screening for visitors and regular temperature taking for staff. Unwell staff should be directed to seek medical attention.
4. More frequent cleaning and disinfection of rooms and work areas.
5. Establish isolation rooms for febrile visitors or staff.
6. Ensure that a contact tracing system is in place.
