Rodent-Borne Virus Blamed in Death

A rare rodent-borne illness killed a 35-year-old chiropractor last week in Montauk, N.Y., state officials said Thursday.

David Hartstein started feeling ill nearly two weeks ago, according to Juline Godin, a close friend of his widow, Heather. At first, he and his wife thought it was the flu or Lyme disease. But before dawn on June 17, Hartstein had trouble breathing and started shaking and sweating, Godin said.

His wife called an ambulance that took him to Southampton Hospital, where his condition continued to deteriorate quickly as doctors scrambled to figure out what was wrong, Godin said. Hartstein died that evening.

Hartstein’s death is just the second confirmed case of hantavirus pulmonary syndrome in the state since 1995, according to the New York Department of Health. The other case was also fatal. There were 20 confirmed hantavirus cases nationwide in 2010 — mostly in the West, according to the department.

The lung infection is caused by a microbe sometimes found in the rodent droppings, saliva or urine. Health officials said Hartstein’s death appears to be an isolated case.

Family and friends suspect that Hartstein inhaled microscopic particles containing the virus while vacuuming out his family’s basement after a small flood nearly a month ago, Godin said.

Godin described Hartstein as a popular figure among East End surfers who was known for walking around town with his dog, a Rhodesian ridgeback named Naya. He and his wife had three young children, all under the age of six.

“He was a very cared-for member of the community,” Godin said. “Everybody knew him as Dr. Dave with the Rhodesian ridgeback.”

The family is staying with friends in the area while their house is cleaned and tested for more hantavirus particles, Godin said.

More Rodents Carrying Hantavirus Found

Six more rodents trapped by County Vector Control technicians last week have tested positive for the sometimes-deadly hantavirus, County officials said this week.

The rodents, four Harvest mice and two California Meadow Voles, were trapped in Fairbanks Ranch and northern Escondido near the San Luis Rey River bringing this year’s total to 16 rodents testing positive for hantavirus, a news release stated. In 2010, a total of 21 rodents tested positive for hantavirus.

“Recent rains have created an abundance of food for rodents, which can increase the rodent population,” said County Environmental Health Director Jack Miller. “More rodents can lead to more hantavirus.” People should never sweep up or vacuum rodent droppings and nesting materials. Instead, ventilate closed areas and use wet cleaning methods with a 10 percent bleach solution or other full strength disinfectant. The best way to prevent the disease is to keep mice out of houses, garages and sheds by sealing all holes larger than the size of a dime, the news release stated.

Wild rodents, primarily deer mice, carry hantavirus. People can contract it by inhaling dust particles from rodent droppings and nesting materials that contain the virus. The virus can cause hantavirus pulmonary syndrome (HPS), which begins with flu-like symptoms, but can graduate to severe breathing difficulties and even death, according to the news release. There is no vaccine or specific treatment for hantavirus and the national Centers for Disease Control and Prevention report that HPS has killed 36 percent of all the people known to have contracted the disease.

How to Avoid Exposure:

• Eliminate rodent infestations immediately.
• Avoid rodent infested areas. Do not stir up dust or materials that may be contaminated with feces and urine.
• Clean up rodent droppings and urine using the wet cleaning method described below.

Use “wet-cleaning” methods to prevent inhaling the virus:

• DO NOT SWEEP OR VACUUM INFESTED AREAS.
• Ventilate affected area by opening doors and windows for at least 30 minutes.
• Use rubber gloves. Spray a 10 percent bleach solution (2 tablespoons bleach to 1 cup of water), or other full strength disinfectant onto dead rodents, rodent droppings, nests, contaminated traps, and surrounding areas and let the disinfectant stand for at least 15 minutes before cleaning. Clean with a sponge or a mop.
• Place disinfected rodents and debris into two plastic bags, seal them and discard in the trash.
• Wash gloves in a bleach solution, then soap and water, and dispose of them using the same double-bag method. Thoroughly wash your bare hands with soap and water.
