Influenza, or flu, is a viral infection of the lungs. There are two main types of flu virus,
A and B. Each type includes many different strains and new strains emerge periodically. Flu
outbreaks occur most often in late fall and winter.
Pandemic flu is a global outbreak of disease that occurs when a new influenza A virus appears in humans, causes serious illness and then spreads easily from person to person worldwide.
What’s the difference between a pandemic and a seasonal outbreak of flu?
A pandemic is caused by a new influenza A virus that most people have never been exposed to, so everyone
is susceptible. Pandemic strains also often cause more serious disease. Because of this, past flu pandemics
have led to high levels of illness, death, social disruption and economic loss.
Seasonal outbreaks of flu are caused by strains of flu virus similar to those of past years. Some people may have built up immunity, and there is also a vaccine for each year’s flu season
When is the next flu pandemic expected?
Three pandemics occurred in the 20th century, all of which spread around the world within one year of being detected.
Of these, the pandemic of 1918-1919 was the most severe, with 50 million or more deaths worldwide.
No one can predict when a pandemic might occur, but many scientists believe it is only a matter of time before the next
one arises. Experts from around the world are watching the H5N1 Avian (bird) Flu situation in the Middle East, Europe
and Asia very closely and are preparing for the possibility that the virus may begin to spread more easily and widely
from person to person
What is New Mexico doing to prepare for Pandemic Influenza?
In New Mexico, pandemic flu planning efforts have been underway for several years. A draft pandemic flu response plan
was developed in 2007 that gives New Mexico a template for dealing with this issue.
Recently, the New Mexico Department of Health has begun efforts to develop a coordinated pandemic flu operational plan that
will focus on continuity of operations of all state government agencies, protecting citizens and sustaining critical
infrastructure and key resources in the event of a pandemic.
NMDOH is leading public information efforts to raise awareness of this issue and to help New Mexicans better understand the
complex issues that will arise if pandemic flu becomes a reality. These include prioritizing who will receive scarce
medications and vaccine supplies and how a pandemic will impact the daily activities we all take for granted such as having
to close schools or cancel sporting events and large public gatherings during a pandemic.
