A year ago, the H1N1 influenza virus emerged out of Mexico threatening the world with an epidemic. This flu outbreak had the makings of a major flu pandemic.
Now a year later, the 2009 H1N1 influenza fears have eased and health officials are reviewing what worked and what did not.
The spread of the 2009 H1N1 flu virus reflected our small world today. The virus emerged in Mexico and quickly spread to North America, Europe and beyond.
Health officials in the United States and around the world quickly ramped up their pandemic operations to address the threat. Their efforts through a little luck and good planning helped prepare and protect the world.
Through research and investigation, health authorities identified the virus's incubation rate, when victims were the most infectious and how to treat the sick patients.
Some criticize the warnings of health authorities, believing the warnings over-reaction, ill advised or incorrect.
How wrong these critics are.
The state, federal and world health authorities did what they are charged to do: investigate, identify and prevent health threat outbreaks around the world.
Yes, the majority of the United State's 270,000 H1N1 flu cases were mild or moderate. This was due to prompt action by the health sector.
America developed vaccine and rolled it out to more than 90 million people, which helped control the outbreak.
Now health officials are reviewing and learning in preparation for the next pandemic threat.
