New AIDS?

Yahoo News- Chagas, a tropical disease spread by insects, is causing some fresh concern following an editorial—published earlier this week in a medical journal—that called it "the new AIDS of the Americas."

More than 8 million people have been infected by Chagas, most of them in Latin and Central America. But more than 300,000 live in the United States.
The editorial, published by the Public Library of Science's Neglected Tropical Diseases, said the spread of the disease is reminiscent of the early years of HIV.
"There are a number of striking similarities between people living with Chagas disease and people living with HIV/AIDS," the authors wrote, "particularly for those with HIV/AIDS who contracted the disease in the first two decades of the HIV/AIDS epidemic."
Both diseases disproportionately affect people living in poverty, both are chronic conditions requiring prolonged, expensive treatment, and as with patients in the first two decades of the HIV/AIDS epidemic, "most patients with Chagas disease do not have access to health care facilities."

Unlike HIV, Chagas is not a sexually-transmitted disease: it's "caused by parasites transmitted to humans by blood-sucking insects," as the New York Times put it. "It likes to bite you on the face," CNN reported.

"It's called the kissing bug. When it ingests your blood, it excretes the parasite at the same time. When you wake up and scratch the itch, the parasite moves into the wound and you're infected."

"Gaaah," Cassie Murdoch wrote on Jezebel.com, summing up the sentiment of everyone who read the journal's report.

Chagas, also known as American trypanosomiasis, kills about 20,000 people per year, the journal said.

And while just 20 percent of those infected with Chagas develop a life-threatening form of the disease, Chagas is "hard or impossible to cure," the Times reports:
The disease can be transmitted from mother to child or by blood transfusion. About a quarter of its victims eventually will develop enlarged hearts or intestines, which can fail or burst, causing sudden death. Treatment involves harsh drugs taken for up to three months and works only if the disease is caught early.

"The problem is once the heart symptoms start, which is the most dreaded complication—the Chagas cardiomyopathy—the medicines no longer work very well," Dr. Peter Hotez, a researcher at Baylor College of Medicine and one of the editorial's authors, told CNN. "Problem No. 2: the medicines are extremely toxic."
And 11 percent of pregnant women in Latin America are infected with Chagas, the journal said.

Cancer Will Kill 13.2 Million A Year By 2030: U.N.

(Reuters) - Cancer will kill more than 13.2 million people a year by 2030, almost double the number who died from the disease in 2008, the United Nations' cancer research agency said on Tuesday.

The International Agency for Research on Cancer (IARC) also said that almost 21.4 million new cases of the disease will be diagnosed annually in 2030.

Launching a new database on global incidence of cancer in 2008, the latest year for which figures are available, the IARC said the burden of cancer was shifting from wealthier to poorer nations.

"Cancer is neither rare anywhere in the world, nor confined to high-resource countries," it said in a statement.

In total, 7.6 million people died of cancer in 2008 and there were an estimated 12.7 new cases diagnosed.

Around 56 percent of new cancer cases worldwide in 2008 were in developing countries and these regions also accounted for 63 percent of all cancer deaths, the data showed.

IARC director Christopher Wild said the data represented the most accurate available assessment of the global burden of cancer and would help international health policy makers develop their responses.

The most commonly diagnosed cancers worldwide in 2008 were lung cancer, with 1.61 million cases, breast cancer, with 1.38 million, and colorectal cancers, with 1.23 million. The most common causes of cancer death were lung (1.38 million), stomach (0.74 million) and liver cancers (0.69 million)

The projection for annual death rates of 13.2 million and annual diagnosis of 21.4 million were based on assumptions that underlying rates of cancer would remain the same over the next two decades, the IARC said.
