Dall, her two children and Alomar continued living together in their Queens home until October 2008, the lawsuit says, althrough she stopped having unprotected sex with Alomar beginning the day of the alleged HIV diagnoses on Feb. 2, 2006.
Dr. David Weber, associate chief of staff at the University of North Carolina at Chapel Hill who specializes in infectious diseases, said that while it's understandable for people to be upset after being potentially exposed to HIV, there is no such diagnosis as "AIDS phobia."
Although symptoms can lie dormant for several years, the disease can be picked up by blood tests between four to 12 weeks after possible infection.
While people can develop any kind of phobia, or irrational fear, Weber said, anxiety in most people tested for the disease dissipates after a negative testing.
He also noted that Dall's concern about the possible infection of her children is likely unwarranted.
The lawsuit alleges Dall's two children were put at risk because they were kissed by Alomar and came into contact with toothbrushes and bathroom facilities he had used.
Although not impossible to contract the disease in this way, the chance of infection through toothbrushes and everyday contact is "vanishingly small," he said.
"I think it's very, very unlikely that a child would have acquired HIV from routine household exposures," Weber said.
If Dall and her children have not tested positive for HIV at this point, they likely won't, he added.
As for the lawsuit, many states have laws that make failure to disclose HIV or AIDS status a crime. But Weber said he knew of no laws that stated a person had to get an HIV test upon a doctor's recommendation.
"If you don't know, how can you tell someone?" he asked. "I don't see how he could be faulted for telling her he didn't have HIV when he didn't know."
Born in Puerto Rico, Alomar had 210 career home runs, according to MLB.com.
The rape alleged in the lawsuit occurred in 1985 after a ball game in New Mexico or another southwestern state, according to the suit.
