Public health agencies in five states are assessing the rabies risk for hundreds of people who may have had close contact with an infected organ donor and four transplant recipients, one of whom died, officials said Saturday.
About 200 medical workers, relatives and others were assessed for potential exposure in Maryland, where the man who received an infected kidney died, state veterinarian Katherine Feldman said.
She said fewer than two dozen were urged to get the rabies vaccine as a preventive measure.
In Florida, about 90 people were identified as potentially exposed, and three were offered the rabies vaccine as of Friday, state health department spokesman Ashley Carr said.
Illinois Department of Public Health spokesman Melaney Arnold said the only potential exposures there were people who worked with the patient or the transplanted organ. She said only the organ recipient is receiving rabies treatment.
Health officials in Georgia and North Carolina are also involved in the epidemiological investigation prompted by the Maryland man's death from rabies in late February, nearly 18 months after he got the kidney from a donor in Pensacola, Fla. However, officials in those states didn't respond to requests from the Associated Press about the number of people they're assessing.
Doctors in Florida didn't test the 20-year-old donor for rabies before he died in September 2011.
His heart, liver and other kidney went to recipients in Florida, Georgia and Illinois. They started getting the vaccine this month, and none has had rabies symptoms. A rabies expert unconnected to the case, Dr. Rodney Willoughby of Milwaukee, said they have a strong chance of surviving since they haven't shown any symptoms.
Health officials say the virus can be spread through the infected person's saliva and mucous membranes, but human-to-human transmission is rare.
The federal Centers for Disease Control and Prevention in Atlanta says there has been only one documented instance of transmission by a bite in the U.S.
Feldman said Friday that the search for potential exposure subjects in Maryland was wrapping up.
She said medical workers typically take precautions, and "we don't share saliva with that many people in our day-to-day goings about."
CDC spokesman Melissa Dankel said investigators are still trying to learn how the transplant donor got infected with the raccoon rabies virus that was found in his brain tissue and that of the Maryland man.
