Summary curves of viral shedding in experimental influenza virus infection, according to the virus type or subtype Peak infectivity is 24-48 hours after infection and lasts ~ 8 days Obviously “sick” persons are more infectious than those mildly ill or those with no symptoms Close contact (living together) increases the risk of person to person transmission So... Don’t send obviously sick people offshore to live and work Carrat, F. et al. Am. J. Epidemiol. 2008 167:775-785
Background Very ill, Hospitalized • Some cases can be prevented • from progressing to this stage • with early antiviral treatment • High risk people • Those with chest involvement H1N1 2009 - The “spectrum of disease” Sick-unable to work Severe The “flu” Typical “cold” No or very mild symptoms At work Severity of illness mild Proportion of people affected So... Ensure workers have reliable access to early medical support - including anti-viral treatment if indicated. EXXONMOBIL PROPRIETARY
What’s this all mean? • Most infected people will stay well enough to come to work • Infected people will show up at work not knowing they are infected but still able to spread the virus. • Obviously “sick” people can clearly spread their infection to others • Workers quartered offshore are at higher risk of person to person transmission due to close working and living conditions • Some people that develop influenza like illnesses are at high risk of severe illness and may need to promptly start anti-viral treatment (no later than 48 hours after symptom onset).
Actions • Advise everyone to try and get an H1N1 flu shot – only available through local health departments • Implement improved hygiene measures to reduce the risk of person to person transmission on offshore facilities (hand washing, sanitizers, not sharing common utensils, cough precautions, etc.) • Ensure obviously “sick” workers are not sent offshore to live and work. • Implement procedures to isolate persons that develop influenza like illnesses while offshore to limit spread of the virus. • Ensure people that develop influenza like illnesses while offshore promptly report and have access to medical support including anti-viral medications when indicated. • NOBODY GETS HURT - EVERYBODY STAYS HEALTHY
