Staff who are identified to perform on-site critical functions should not come to work under any of the following circumstances:

• They are feeling unwell, or have any cold/flu type symp-toms (headache, fever, sore throat, cough, body aches, runny nose, nasal congestion, abdominal pain, cramps or diarrhoea). Staff will be advised to check their body temperature each morning and evening. No staff mem-ber should go to work if the measured temperature is higher than 38°C (100.4°F);
  
  
• One of their family members has or is suspected to have influenza;
  
  
• They are aware that they have had recent contact (<48 hours) with someone who is now known to have con-tracted pandemic influenza.

Any staff member who becomes ill should be asked to stay at home for 10 days from the onset of fever (or longer if the case is compli-cated). In addition he/she should, as soon as possible, start a course of Oseltamivir (Tamiflu) or other recommended prescription medicine and wear a simple surgical mask when meeting other people.

Persons who have been exposed to a known case of pandemic influenza should also be asked to stay home for the period of 10 days, from the first known exposure to the virus, to cover the maxi-mum incubation period.

If a staff member has a relative or someone else at home sus-pected of being affected by pandemic influenza, he/she should be monitored at least daily for fever and respiratory symptoms and not come to work for 10 days after the resolution of fever of the infected household member.
