The world was seemed ready to handle any case involving influenza pademic. However when the pandemic arrived in 2009, all people were perplexed. Looking back, many gaps in pubic health were found. Among the recommendation to fight the influenza pandemic included: monitoring of the flu outbreak, better communication, and vaccine prognostication.
Post-pandemic review suggested that concerns should not be directed to humans. The world is supposed to deal with the swine population and the virus itself. The reason is that pig is an agent for both viruses that affect people and those that attacks birds. The swine respiratory tract act as a good environment in which the pandemic influenza develop.
Avian influenza cannot attack humans. The virus has to adapt to the human breathing tract. While in the pig, avian viruses mutate to develop new strains that can easily affect human. When the new strains are introduced to human respiratory tract, they cause worse symptoms which can easily lead to death.
The pig-based infection has previously been regarded as high for a long period of time. They had been calls for surveillance to control the spreading of the virus. After the 2009 pandemic, there were louder calls to monitor flu viruses. Some studies have examined swine in various regions such as China and Europe. The results have shown that pandemic strain is circulating and may end up back to the people.
According to the research, there is need to have a viable surveillance system to monitor two main types of influenza. The first influenza is human origin; that is any strain which can directly infect humans. By understanding its evolution, we can possibly develop vaccines before the flu spread.
The second influenza is avian. Proper monitoring of this virus will enable us to find the strain before it attack humans. This will not only improves human health, but also drive fear of the virus away.
