Exotic Diseases in the U.S. May Rise

We know about Dengue Fever, West Nile Virus and Lyme Disease - but have you heard of Leishmaniasis Disease, Chagas Disease and/or Chikungunya Virus?

Probably not, unless you've been to places outside of the U.S. where these diseases and viruses are thriving. However, Americans could come to know these intimately for two reasons:

• Rapid international travel;
• The recession.

The former seems immediately logical, while the latter takes some explanation.  One thing we do know, is that each of these diseases and viruses still kill millions worldwide.

These are called vector-borne diseases, which is basically an organism that does not actually cause the disease, but transmits the infection by carrying pathogens from one host to another. When a disease is transferred from animal to humans - the process is called Zoonosis.

Insect contamination is another, more well known method of disease and virus transference to humans. While commonly thought that rats were the culprits of plague, it's now known that the fleas on rats are the actual carriers.

Zoonosis in the U.S. may happen with bats, birds, cats, cattle, dogs, fish, fleas, flies, geese, goats, hamsters, horses, lice, mice, mosquitos, opossums, pigs, rabbits, hares, raccoons, rats, other rodents, sloths, sheep, snails and ticks.

I'm betting that there were at least a few surprises in that list!

Of these aforementioned diseases, malaria is probably the most well known tropical disease, topping more than 200 million cases per year (around the world) - 1 million of which end in death.

At the same time, such vector-borne diseases are capable of spreading around the world much more rapidly due to massive south-to-north immigration, rapid transportation, and global trade.[/q]Duane Gubler, Director of the Duke/NUS Graduate School of Medicine Emerging Infectious Disease Program in Singapore, had this to say:

A report coming from the Trust for America's Health, explains that budgets for public health in the U.S., are suffering desperately and are currently $20 billion underfunded because of the economic downturn - and that doesn't even include research for tropical diseases.

One budget cut for example is that of King County in Washington, who were forced to cut around $19 million in the 2009 budget.

Dr. James Maguire, former chief of the CDC's parasitic diseases branch and now a Harvard Professor explains:

When asked what the current budget is, the CDC were unable to provide a definite amount, but estimated it at less than $75,000 - which didn't include staff salaries.

In an example of mixed governmental priorities, anti-tobacco advertising was allocated a whopping $103.7 million.

Dr. Ali Kahn, deputy director of the National Center for Zoonotic, Vector-Borne and Enteric Diseases at the CDC tells us:

Pretty much a no-brainer statement.

The recession is hitting everyone hard, with harder days yet to come. Despite murmurings of "it's hit rock bottom, and we can only improve," those in the know, incredulously drop their jaws.

Be aware, no matter what the politicians tell you: There is NO bottom in sight, let alone recovery and probably will not be for a few years to come. The government is also weakened by the recession and has only little ability to develop new vaccines or improved treatments to prevent epidemics.

Dangerous or life threatening diseases such as leishmaniasis and Chagas disease are found in more than 13 million people in the world - how long do you think it will be before people will suffer - even die with them here in the U.S.?  These two diseases were only allocated 4.9% of total funds.

The housing industry is suffering badly too, with constructions still showing half finished skeletons, as work came to a deadly halt.  Puddles of water at construction sites are prime breeding grounds for all types of dangerous insects.

To some degree we can help ourselves by making sure that old tires, cans, pottery containers etc., are kept free of water or turned upside down so that puddled water doesn't form.

The eSSORTMENT website paints an even darker picture, by mentioning many other diseases that we need to monitor:

Believe it or not, this is still not a complete list of what could be transmitted into the United States. If we, the public want to help gain more funds from the government, the onus is on us - the public,  to ensure that certain events happen.

Researchers at the George Institute in Australia have this advice for us:
