Pandemic – When did the definition change?

The old version:

WHO_Pandemic_preparedness_May_1_2009

An influenza pandemic
An influenza pandemic occurs when a new influenza virus appears against which the human population has no immunity, resulting in epidemics worldwide with enormous numbers of deaths and illness. With the increase in global transport, as well as urbanization and overcrowded conditions, epidemics due the new influenza virus are likely to quickly take hold around the world. Outbreaks of influenza in animals, especially when happening simultaneously with annual outbreaks of seasonal influenza in humans, increase the chances of a pandemic, through the merging of animal and human influenza viruses. During the last few years, the world has faced several threats with pandemic potential, making the occurrence of the next pandemic a matter of time.

and the new version:

WHO_Pandemic_preparedness_webpage_Sept_2_2009

What is an influenza pandemic?
A disease epidemic occurs when there are more cases of that disease than normal. A pandemic is a worldwide epidemic of a disease. An influenza pandemic may occur when a new influenza virus appears against which the human population has no immunity. With the increase in global transport, as well as urbanization and overcrowded conditions in some areas, epidemics due to a new influenza virus are likely to take hold around the world, and become a pandemic faster than before. WHO has defined the phases of a pandemic to provide a global framework to aid countries in pandemic preparedness and response planning. Pandemics can be either mild or severe in the illness and death they cause, and the severity of a pandemic can change over the course of that pandemic.

The two documents above can also be found at: http://attentiallebufale.it/informazione-scientifica/speciale-bufale-pandemiche-come-difendersi/lanalisi-di-doshi-al-voltafaccia-delloms/

These two documents were sourced and provided by Dr Tom Jefferson, and  Peter Doshi.

And here is Fukuda, at WHO, claiming that they didn’t change it!

Now let me move on to the second issue. Did WHO change its definition of a pandemic? The answer is no, WHO did not change its definition.

H1N1 Influenza in the U.S.

While it’s too soon to be sure,  influenza numbers are dropping and the season may be coming to an early close. The CDC has these numbers:

During week 51 (December 20-26, 2009), influenza activity decreased slightly in the U.S.

154 (3.9%) specimens tested by U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories and reported to CDC/Influenza Division were positive for influenza.

Translation: of thousands of tested cases of “might be flu”, 154 turned out to really be flu, only 3.9% of the total specimens tested. Lots of sneezing and coughing out there, and not an insubstantial number of hospitalizations and deaths for “influenza-like-illness and pneumonia” , but no influenza viruses are the main cause at this point.

2009 H1N1 virus did turn out to be more dangerous to children than the typical yearly influenza virus: the CDC received 225 reports of deaths this year, 130 last year, 88 in 2007 and 78 in 2006.

The breakdown by age:

Since August 30, 2009, CDC has received 225 reports of influenza-associated pediatric deaths that occurred during the current influenza season (42 deaths in children less than 2 years old, 25 deaths in children 2-4 years old, 83 deaths in children 5-11 years old, and 75 deaths in children 12-17 years old).

How likely was a child under 2 to die from H1N1 based on these numbers?

Live births in 2007: 4,317,000, minus 29,000 infant deaths, gives us a starting number of 4,288,000.  The number of births has been going up every year for the last few years, so if we assume the same number in 2008 we are erring on the side of caution. We’ve got a total of roughly 8,576,000 children in the U.S. under the age of two. Forty-two of those children died this year as a result of H1N1, according to the CDC.  This means that one child out of every 204,190 died from 2009 H1N1 according to the reported number of cases.

Are the reported number of cases reflective of the true burden of illness? Probably not entirely, but in November, CBS news reported that:

It’s a little counter intuitive,” Frieden said, “but the best way to estimate the total burden of illness is not to count the cases, but to estimate them based on the best available science.”

However, Ashton pointed out, things are very different when reporting pediatric flu deaths. She said states are required to document each case with the CDC, and every week the updated numbers are an accurate reflection of the entire country.

The numbers of pediatric deaths from 2009 H1N1 are based, therefore,  on actual case counts in the U.S., during 2009.

Infants and toddlers were one of the groups recommended for the 2009 H1N1 vaccine. However, if saving the maximum number of lives is our goal, then there are several other causes of death in infants and toddlers which we feel should be addressed with a vigor to match the actual death and injury rates for each category.

Among 1- to 4-year-old children, injuries accounted for 42 percent of all deaths, followed by deaths due to congenital malformations (birth defects), malignant neoplasms (cancer), homicide, and diseases of the heart.

Or to give some comparative numbers:

More than 16,500 lives could be saved each year in the United States alone if our under-5 mortality rate was the same as Iceland. If the U.S. rate of under-5 mortality was similar to that of France, Germany and Italy (all 4 per 1,000 live births), over 12,000 child lives could be spared.

The causes of child deaths in the industrialized world differ dramatically from those in developing countries. In the developing world, over half of under-5 deaths are caused by pneumonia, diarrhea or newborn conditions. In the industrialized world, these problems rarely lead to death. Children’s deaths are most likely the result of injury suffered in traffic accidents, intentional harm, drowning, falling, fire and poisoning.
