Another bug to fear?

Ebola is not the only disease getting media coverage. It seems that another disease called chagas is in the headlines along with the insects that transmit it. Perhaps one of the names of this nasty insect, kissing bugs, implies a less-than-dangerous illness. But chagas can remain in a human for months and even transmitted to newborns.

Doctors are slowly becoming aware of the dangers of this disease that is predominantly afflicting Bolivians, many of whom live in Northern Virginia. But a map on the Centers for Disease Control website shows the entire southern US reporting this insect.

According to the World Health Organization: Triatomine bugs are large bloodsucking insects that occur mainly in Latin America and the southern USA, frequently in homes made of mud and with thatched roofs. A number of species have adapted to living in and around houses and are important in the transmission to humans of Trypanosoma cruzi, the parasite that causes Chagas disease (also known as American trypanosomiasis). Chagas disease, which occurs in most South and Central American countries, is incurable and in its chronic phase may cause damage to the heart and intestines. Some patients eventually die from heart disease.

WHO also estimates that 8 million people have Chagas disease worldwide, most of them in Latin America. The triatomines, or the so-called kissing bugs, bite people at night, passing the parasite through their feces. The bite itself is painless, and many people never show any signs of the disease. A third of those with Chagas, however, develop heart disease or megacolon, and untreated, they die from what appears to be heart attacks. An estimated 11,000 people lose their lives every year to the disease.

Chemical sensitivity is more than an allergy

The Green Lodging blog included a recent posting on multiple chemical sensitivity (MCS) that caught my attention. Hotels are infamous for introducing "smells" into their rooms and I have found a few to be overwhelming. Fragrances in many retail stores also drive me back out their doors.

But folks tired from driving or long airline flights usually do not complain beyond finding bedbugs or the smell of cigarettes as they crash into hotel beds. But perfumes, VOCs from newly painted rooms, and cleaning and laundry products' lingering odors can be more problematic to quite a few people. 12% of humans may suffer from MCS. More from pet dander, dust mites and mold.

Antibiotics in our meat?

Hmmmm. It seems that a U.S. Court of Appeals decision this week may result in continued antibiotics in our meat and poultry. The FDA has been looking into the meat industry's practice of adding antibiotics to their animals' diets to promote growth and prevent disease, but this decision says that agency is off the hook in decision making.

Cargill recently announced they will stop adding antibiotics to promote faster growth, but no mention of stopping it altogether.

And antibiotic-resistant diseases are in recent headlines too. That flesh-eating one that one can catch by swimming in saltwater, if you have a small scratch, certainly has my attention.

So it looks like organic turkey will be on my Thanksgiving shopping list.

One step closer to offshore drilling?

Attention: whales, dolphins, turtles and other sea life. Get out your earplugs and shut down your echolocation devices. Sonic cannons will be coming soon to offshore Virginia. Actually anywhere from Florida to Delaware. 

Loud sonic cannons too. 100 times louder than jet engines. And every 10 seconds or so, bouncing back info to oil companies looking for the most likely spots to drill for oil and gas after 
2018. 

WHY? An estimated 4.72 billion barrels of recoverable oil and 37.51 trillion cubic feet of recoverable natural gas may lie beneath federal waters from Florida to Maine. Opening it to drilling could generate $195 billion in investment and spending between 2017 and 2035, creating thousands of jobs and contributing $23.5 billion per year to the economy. Could

So sea life, listen up.

Chigger season is here in Virginia

These darn almost microscopic mites are making outdoor living miserable for a lot of us in Tidewater Virginia. One look behind my knees and more tells you that they thrive in the tall grasses and shrubs in my yard. Or maybe I found them while searching for a lost golf ball.

Contrary to popular belief, chiggers do NOT burrow into your skin. So coating the bites with nail polish accomplishes nothing. 

The nymph form find a spot on your body with some restrictive clothing and then settle down for some fine dining. They inject a digestive enzyme that literally liquifies your skin cells and lymph, so they can suck them up. You don't feel the bite for quite a few hours and the itching begins a day or so later. REALLY big time itching. 

Calamine lotion or other prescription anti-itch medications relieve some of the itching for a short while. And the itching seems worse at night.
