New Virus May Be Dangerous but Seems Not Easily Spread

By MARC SANTORA

A new strain of a potentially deadly virus related to SARS, which has killed one man in Saudi Arabia and left a Qatari man critically ill in London, does not appear to spread easily from person to person, the World Health Organization says.

Still, officials are urging vigilance, saying that health workers around the world should be on the lookout for anyone with acute respiratory syndrome and requiring hospitalization who had been in the Middle East, where the virus first surfaced, or in contact with a suspected or confirmed case within the last 10 days. On Saturday, the health organization, which was rushing to develop a diagnostic test, said that doctors should test for the virus only if the patient is severely ill, so as not to overburden the health care system.

Better Hepatitis C Treatment Is Costly for Texas Prisons

By BRANDI GRISSOM

Tattooing is ubiquitous behind bars, despite — or perhaps because of — the fact that it is banned.

“It’s just unbelievable how creative they can be,” said Michele Deitch, a prisons expert at the University of Texas at Austin’s LBJ School of Public Affairs. “They can jerry-rig pens to become needles. They use the dyes in paper products.”

But the practice carries with it more than the risk of punishment — it can also spread hepatitis C.

The prison population is particularly prone to this viral disease, which is transmitted largely through infected blood and can lead to liver cirrhosis and cancer. Not only do inmates have a penchant for illicit tattoos, but they are also likelier than the general population to have engaged in high-risk behavior like intravenous drug use outside of prison. Prison health officials estimate that as many as 50,000 of the state’s more than 150,000 inmates could be infected with hepatitis C.

The cost to treat Texas inmates with hepatitis C is expected to soar by as much as 380 percent next year, a result of the growing prevalence of the disease among inmates and a more effective, but more expensive, treatment protocol. Legislators, already facing a strained budget, will have to find millions more dollars to pay for this care.

Not all inmates are tested for hepatitis C when they enter the prison system. They are tested if they have other clinical indicators, like H.I.V. or a history of intravenous drug use. In a 2007 report, health providers for the Texas Department of Criminal Justice said they had identified and were managing care for about 20,000 inmates with hepatitis C.

Dr. Stephanie Zepeda, the director of pharmacy services for University of Texas Medical Branch Correctional Managed Care, which oversees treatment of inmates, said she provided medication therapy for about 400 hepatitis C patients per month, at a cost to the state of about $2.8 million per year. Not all patients with the disease receive the medication, and the therapy can last from three months to a year.

The current protocol is composed of two drugs, and its cure rate is about 40 percent, Dr. Zepeda said. But new medical guidelines call for the use of a third medication, which can be one of two different drugs. One of them would increase the cost of hepatitis C treatment in prisons to more than $8 million a year, the other to more than $13 million, Dr. Zepeda said.

Dr. Zepeda said that adding a third drug raised the cure rate to 70 percent. But the drugs are not only expensive, they are also complicated to administer.

“It’s great from a humanistic standpoint,” Dr. Zepeda said. “But it’s, practically, a challenge for the correctional system.”

Unpredictability in Dallas West Nile Virus Outbreak

By MANNY FERNANDEZ

DALLAS — Jay Wortham found it under the cabinet below the kitchen sink after his mother died in August — a blue bottle of insect repellent.

His mother, Margorie Wortham, 91, died of West Nile virus, the mosquito-borne illness that has spread across this city and other parts of the country, killing 118 people and sickening nearly 3,000 others nationwide.

Mr. Wortham believes that his mother was bitten by an infected mosquito one hot day in July while she sat on an old wooden bench under a pecan tree in her backyard. Though she had often used the bug repellent, she was not wearing any that day.

Here in Dallas County, the West Nile outbreak’s hardest-hit county in the United States, a few missed pumps of bug spray can haunt the relatives of those who die from the virus.

“I wish I had taken her this instead of a vodka and Coke,” said Mr. Wortham, 59, holding the bottle in his hands. “I ask that other people don’t make the same mistake.”

Ms. Wortham and 14 other people have died in Dallas County from the virus since July. Nine were men, and six were women. The youngest were in their 40s, and the oldest in their 90s.

Charles H. Pistor Jr., 81, was a well-known figure in Dallas — a retired banking executive, former vice chairman of the board of trustees at Southern Methodist University and past president of the Dallas Assembly civic group.

Dr. Tom M. McCrory, 92, a retired eye surgeon, died eight days after Mr. Pistor in July.

Dema Miller lived in the Dallas suburb of Irving and was one week shy of her 84th birthday when she died in August.

Local and federal health officials said the outbreak that has killed 57 people and sickened hundreds of others in Texas appeared to be waning, with Dallas County seeing a decrease in new cases in recent weeks. Still, the friends and relatives of the county’s fatal victims remain in a state of grief, coming to terms with the seeming randomness of healthy middle-aged people and active retirees cut down by ever-present insects.

Waiting and Worrying After Yosemite Hantavirus Outbreak

Waiting and Worrying After Yosemite Hantavirus Outbreak

By PETER JARET

Bears were the only thing to worry about during our stay at a tent cabin in Yosemite National Park in August, or so my husband and I thought. We scrupulously emptied the car of food and anything a bear might mistake for food, including empty wrappers and scented items like soap. We cleaned every crumb of trail mix from our tent. We stashed everything that might attract a bear in metal lockers provided by the park.

As it turns out, we should have been worrying about a much less obvious threat.

By the time Steven and I returned home, the news reports had begun to appear. An outbreak of hantavirus infection in Curry Village, a popular camping area in Yosemite Valley, had killed two people. Four others had been sickened. But we had camped at Tuolumne Meadows, one of the High Sierra Camps at the far eastern border of the park, miles from Curry Village. We had nothing to worry about.

Then, on Sept. 6, an e-mail arrived: an official notification from Yosemite National Park. “You are receiving this advisory because you have recently stayed in the High Sierra Camps at Yosemite National Park, and we want to inform you — and any members of your party — about a potential public health matter that has been brought to our attention.”

Gulp.

Another case of hantavirus infection had been identified, this one in a camper who had stayed in the High Sierra area where we’d camped. “It is recommended that if a recent visitor to Yosemite National Park exhibits any symptoms,” the e-mail went on, “that they seek medical attention immediately and advise their health care professional of the potential exposure to hantavirus.”

Weirdly, the e-mail featured an inviting panoramic photograph of the Yosemite peaks towering against a clear blue sky.

As a science writer, I knew hantavirus could be swiftly lethal. The virus and the disease it causes, called hantavirus pulmonary syndrome was first discovered in 1993, when a terrifying outbreak began to unfold in the Four Corners area of New Mexico, Colorado, Utah and Arizona. One of the first cases was a healthy 19-year-old man who was a marathon runner. A day after coming down with flulike symptoms, he went to an emergency room. Three days later he was dead. Medical detectives soon discovered that the man’s fiancée had died days earlier, also from a runaway respiratory infection.

Researchers have since learned that deer mice transmit the virus in their droppings, urine and saliva. People become infected when they inhale particles contaminated with the virus. The first symptoms are varied — fatigue, fever, chills and muscle ache — but the infection can progress within 10 days to coughing, nausea, respiratory difficulty and death.
