...advanced, Pap smears are the only way to detect the malignancy early. Some gynecologists recommend the test every six months for women with more than one sexual partner, and more frequently for those who have had warts. Even when the warts disappear spontaneously or are medically removed, the underlying viral infection -- and therefore the risk of cancer -- may persist. Hoping to reduce that risk, doctors are testing the antiviral substance interferon in adults with severe warts, and efforts to produce a vaccine are also under way. But no solution is close at hand. The prospect is for another sexually transmitted...
...parts of Africa, and general standards of hygiene and medical care are low. Scientists believe widespread venereal diseases in Africa also contribute to the spread of AIDS by causing genital ulcerations that make it easier for the virus to enter the bloodstream. Finally, Africans suffer from more nonvenereal viral and parasitic diseases than do Americans, and the Africans' overtaxed immune systems may be more vulnerable to the AIDS virus...
...worked for a time as a waitress, got married, went broke, lived on the dole. She was so run-down when her son Benjamin was born that he weighed only 4 1/2 lbs.; he survived in an oxygen tent, receiving blood injections. During that hospital stay, he contracted a viral infection that left him partly blind, deaf, hydrocephalic, brain damaged. After three months, the hospital released him and told Holly to give him phenobarbital when he had seizures. She took him to a welfare hotel near Times Square. Five weeks later she was evicted. She says it was because...
...long time but just wasn't recognized," Elvin-Lewis explains. It is possible, Tulane's Garry speculates, that the AIDS virus mutated and became more lethal in the 1970s. To test that hypothesis, he plans to spend much of the next year or so attempting to reconstruct viral genes from Robert R.'s tissue. "We know that the virus was not epidemic in 1969, so we might be able to identify the changes between then and now that enabled it to spread," Garry says. If scientists can figure out how the AIDS virus might have changed, the puzzling case from...
...projects that the center has worked on, it gained the most notoriety for its efforts to stop a viral epidemic among the lab monkeys in 1979. The disease attacked the monkeys' immune systems and weakened them--a pattern that had yet to become ominously familiar. Researchers studying the disorder found that it was similar to the human disease now known as AIDS...
