What Do You Fear Most: H1N1 or EEE?

by Fran Jurga | 19 September 2009 | The Jurga Report at Equisearch.com


If you turn on the news (or do you just not turn it off?), you will hear a lot about H1N1, or the "coming plague" that seems destined to hit us this fall, but the mosquitoes are having a field day on the east coast and gulf coast.

You'll hear that a man in central New York State has died from Eastern Equine Encephalitis (EEE).

Randomly-trapped mosquitoes all over eastern Massachusetts have tested positive for EEE and in some towns near Cape Cod, state health authorities have raised the alert level for mosquitoes from moderate to high after discovering that mosquitoes there were infected with not one but two viruses dangerous to humans--both EEE and West Nile virus (WNV).

In Maine, 14 horses have died from EEE.

In Virginia, seven horses have died from EEE and one from WNV. Wherever you look, the story is the same. Louisiana has been hit hard as well.

Outdoor after-school activities are being canceled for children and northern New England is gearing up for the big country fair season, but public health officials are urging people to take precautions.

When I was a little girl, a family friend was bitten by a mosquito at a horse show (don't ask me how they knew exactly where the bite happened) and she became ill with EEE. It was horrible, but she did survive. My parents never allowed us to go to an event at that fairground ever again and I have never forgotten that EEE is a real risk to humans and horses.

And it's not over yet. Mosquito season can and will last until November in many areas. A frost should be coming to Maine any day now, and it will be welcome, in terms of killing the mosquitoes.

Assuming that your horses are vaccinated and you have checked to find out if fall boosters are needed or not, take the time to review the basic prevention steps with everyone who lives or works or plays on your property:

• If possible, stay inside between dusk and dark, when mosquitoes are most active.
• When outside between dusk and dark, wear long pants and long-sleeved shirts.
• Use an insect repellent with DEET or Picaridin according to manufacturer's directions when outside. Oil of lemon eucalyptus and IR3535 have been found to provide protection similar to repellents with low concentrations of DEET.
• Put screens on windows and make sure they do not have holes.
• Eliminate standing water and other mosquito breeding locations from your property. Do not alter natural water bodies.

And what about our own flu shot? The fall and early winter are great times for riding, plus there are so many year-end shows and events to attend -- don't miss any of it if you can help it! Find out about both "regular" flu and H1N1 innoculations and what your risk factors are. And if you get sick, stay home.

Which do I fear? EEE, no doubt about that. What do I dread? H1N1, because even if it doesn't happen, it will disrupt our lives in some way and have more of a direct effect. But those of us who are outside and/or live near mosquito-invested zones have to take the warnings seriously.

It's a matter of life and death, for humans and horses.

Are you around horses that haven't been vaccinated? A lot of people opted to save money this spring and skipped EEE, especially in areas where the disease hasn't been a problem. That's what happened in Maine. Be sure you know what the symptoms are.

And please don't stay home from the fairs, unless you are at high risk for complications of the flu. Country fairs are vital to regional economies and one of the last great ways to get out and connect with rural traditions and your agricultural friends and neighbors. Please support them...just make sure you have some repellent handy, cover up, and wash your hands a lot.

See you there!

UPDATE: Since this post was originally written, the first case of EEE ever reported in Maritime Canada has resulted in the death of a horse in Nova Scotia.

Counting Medals? Count Mosquitoes, too!

A lot of people are counting medals this week. Will Germany dominate? Are you rooting for Isabel or Anky? Was Australia robbed of the Eventing Gold it deserved?

Take a minute today to look up from the Olympics your television or your monitor and check with your local or state health department. What are the West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE) risks in your area?

Today we have the first announcement of EEE in the state of Wisconsin, and the fifth case of EEE in Marion County, the area around uber-horsey Ocala, Florida. Seventy-two horses have been diagnosed with EEE in Florida so far this year.

Two horses in Orange County, California tested positive for EEE. West Nile Virus was recently found in mosquitoes tested in Vermont.

And it doesn't end there. Just a few of the alerts on hand include WNV in Oak Park, Illinois; Greenwich, Connecticut; Salinas, California, and Minnehaha, South Dakota.

EEE recently showed up in Craven County, North Carolina and Carroll County, Tennessee.

Vermont is having one of the worst mosquito seasons on record. Just how many mosquitoes are out there? It sounds like Vermonters have a lot of time on their hands. One researcher set out to determine just how many mosquitoes inhabit an acre of land...they're still counting.

Keep these three facts in mind: 1) Both diseases are carried by mosquitoes; 2) Both diseases can also be transferred by mosquitoes to humans; and 3) Both diseases are highly preventable with a simple vaccination program.

Florida Horse Health Alert: 2008 EEE Deaths Up to Nine

Part of the problem with mosquito-borne illnesses becoming more prevalent is the mosquito itself. The Asian Tiger Mosquito (ATM) has invaded the southeastern USA; it was carried from Asia in container loads of used tires that were not inspected for mosquitoes and falls under the heading of "invasive species". This new breed of skeeter is particularly well-suited for spreading diseases. The University of Florida is trying to educate people that the mosquitoes around them have changed their stripes.

As convoys of horse vans and trailers prepare to head north from Florida after the winter polo, horse show and racing seasons end next month, the warm climate that lured horsemen to the Sunshine State may play a cruel and deadly trick on them.

Already, nine cases of Eastern Equine Encephalitis (EEE) have been confirmed in Florida since the beginning of 2008, even though the peak season does not begin until May. There were a total of 18 cases of EEE in 2007 for the entire year.

Sadly, according to the Florida Department of Agriculture, six of the dead horses had not been vaccinated and two had not received booster shots. Only one horse was current with vaccinations.

EEE is a viral disease that affects the central nervous system and is transmitted to horses by infected mosquitoes. Signs of the virus include fever, listlessness, stumbling, circling, coma and usually death. The disease is fatal in horses in 90% of the cases.

So far this year EEE has been confirmed in horses in Putnam, Lake, Polk, Columbia, Clay and Volusia counties, all of which were fatal. Volusia has been hit the hardest, with four of the nine cases having been found there.

If you live in Florida and if you have been in the state with your horses recently (or plan to go), please consult your health records and be certain that the horse's vaccination status for EEE is up to date.
