The Definition of Pandemic

Monday, June 15th, 2009

Guest Post:

The word pandemic has been thrown around in recent years because of the prevalence of many major illnesses that have occurred throughout the third world nations as well as even many Western nations. However, the recent Swine Flu outbreak has caused much deliberation as to the proper terminology of the word itself.

There have been generations of widespread epidemics in the past that have included influenza, cholera, and a multitude of other diseases. However, the World Health Organization has come up with a six-tiered level in which to determine when to implement specific disease control efforts around the world, which has successfully led to many countries quarantining illnesses which could be easily spread abroad. However, the true definition of a pandemic is not delivered by the WHO nor can medical journals accurately define it as well. Rather, the general public is on its own to determine what a pandemic ensues, as it implies the “rapid spread of an infectious disease to many countries”. However, the severity of pandemics vary with each disease, and not every country is affected when an outbreak occurs.

Additionally, the variety of different illnesses affects the overall terminology of the word; scientists and doctors alike are still unsure as to how pandemics arise, how they spread, and why they vary in their lethality. The background of the originating country has a lot to do with the severity and contamination of the impending illness and helps contribute to the overall definition of a pandemic. The recent Swine Flu outbreak has increased concerns over the spread of a disease within these “Western nations” which otherwise were remarkably protected from threat of outside illnesses that could infiltrate these nations. The fact that the United States was one of the first countries to report signs of such a disease caused the WHO to scramble to upgrade their alert system in order to properly take care of this problem. It is unfortunate that it takes a Western nation to cause this much concern over an illness, while many African nations have been experiencing similar epidemics. The new limelight on these Western nations is solely due to the international trade that occurs within many of these nations, which therefore caused the disease to be spread throughout Europe, Asia, and Australia.

This new illness caused the WHO much stress as to a proper cure for the illness as well as a way in which to quarantine travelers from disease-ridden countries. While the illness can be treated with regular flu remedies, the fact that so many outside the tradition flu age group were coming down with the illness and succumbing to its side effects caused the WHO to take drastic measures and qualify it (perhaps prematurely) as a pandemic. This recent flu outbreak is vastly different from any earlier outbreaks which may be labeled as “true” pandemics, but this type of definition is forever changing and it may take another widespread illness before we can determine what is the proper scenario in which to classify as a pandemic.

Eradicating Polio – The Final Inch

Wednesday, November 19th, 2008

Poliomyelitis is a deadly disease which may affect the central nervous system leading to irreversible flaccid paralysis of the legs. Since it strikes children at a very young age, affected children are paralyzed for their entire life.

Google’s philanthropic arm – Google.org is about to release a movie titled “The Final Inch” to document the historic effort to eradicate this disease from the planet. Once we succeed this will be second disease after small pox to be found only in history books (and/or some covert lab, somewhere in the world).

The Final Inch is a 38-minute film about the historic global effort to eradicate polio. Here, the story told is as much about the messengers as the message. You’ll meet Munzareen Fatima, one of the thousands of community “foot soldiers” across India working to sway reluctant families to vaccinate their children, and Dr. Ashfaq Bhat, who travels into the backwaters of India’s Ganges Basin by boat and foot to detect emerging cases of polio. Martha Mason and Mikail Davenport bring us into their lives and describe the paralyzing challenges of childhood polio, reminding us how endemic polio once was in the United States.

Filmed in high-definition (HD) in cinematic style — wide open shots to give a strong sense of place — The Final Inch captures their stories, and we hope it is both a tribute and an inspiration of hope. With a final push, this is a disease that can, and should, be eradicated finally.

The movie airs on HBO in 2009. Check out the film trailer:


Genes to the Rescue: Breakthrough in Autism

Friday, September 26th, 2008

Scientists have a discovered a gene called Npas4 that keeps brain activity in check. Targeting this gene may one day lead to drugs that can help autistic children.

Scientists say they have pinpointed a gene in the brain that can calm nerve cells that become too jumpy, potentially paving the way for new therapies to treat autism and other neurological disorders.

The brain is continually trying to strike a balance between too much and too little nerve cell activity. Neurologists believe that when the balance tips, disorders such as autism and schizophrenia may occur. They are not sure why neurons (nerve cells) go berserk. But Greenberg (Neurobiologist at Harvard Medical School) says he and his colleagues located a gene in mice and rats that helps keep neural activity in check—and may one day be manipulated to prevent or reverse neurological problems.

National Health Expenditure

Monday, August 25th, 2008

How far can we go before the health system breaks down? What is the government doing to prevent it?

This chart shows the national expenditure on health care (in billions) since 1960. In 2004, the $1.87 trillion spent on health care represented 16 percent of the Gross Domestic Product (GDP). In other words, health care took 16 cents of each dollar spent in 2006. By 2015 some forecast that 1 out of every 5 dollars in America will go to health care.

Rising incidence of Measles

Sunday, August 24th, 2008

In contrast to my earlier post, Measles vaccine is very effective and should be given to each and every child. Failure to vaccinate children is leading to to measles outbreaks which will increase in the future. Furthermore, the risk of contracting measles (with its attendant complications) far outweigh the risk of developing autism.

More people had measles infections in the first seven months of this year than during any comparable period since 1996, and public health officials blamed growing numbers of parents who refuse to vaccinate their children.

Many of these parents say they believe vaccines cause autism, even though multiple studies have found no reputable evidence to support such a claim.
