caused by viruses circulating in animals Animal flu virus causes infection in humans,
and is a potential pandemic threat Flu causes sporadic cases in people, but no significant human-to-human transmission Human-to-human transmission
and community-level outbreaks Human-to-human transmission in at least two countries. Strong signal pandemic imminent Virus spreads to another country in a different region. Global pandemic under way H1N1 Flu Virus Influenza A virus classified by two proteins hemagglutinin (H) neuraminidase (N) Spreads easily through
coughing and sneezing No severe symptoms,
but can be deadly Related to 1918 Spanish Flu which killed 40-50 million people and infected 50% of the world's population same strain that causes seasonal outbreaks Symptoms same as seasonal influenza fever cough sore throat chills fatigue body aches Vaccination is the primary strategy for the prevention of influenza No current vaccine in circulation although one is being tested the most effective way to prevent influenza is to prevent human-human contact Not Possible Humidity 35-40%
Temperature 28˚C Virus survival Hard non-porous surfaces 24-48 hours Plastic/stainless steel Recoverable for > 24 hours Transferable to hands up to Cloth, paper & tissue Recoverable for 8-12 hours Transferable to hands 15 minutes The virus has The avian, swine, and human viruses
