For the first time, doctors are reporting that a child born with HIV and put on an unusually aggressive treatment regimen has been functionally cured of the infection. Now 2 years old, the Mississippi girl has only trace amounts of HIV in her bloodstream and has been able to keep the virus that causes AIDS in check without the help of medication, doctors said Sunday at a medical conference in Atlanta. If researchers demonstrate that the same treatment can work in other children, it could drastically alter the lives of the estimated 1,000 babies born with HIV every day, most of them in Africa, doctors said.

There is no cure for AIDS, no good treatment to control its symptoms for long periods and no vaccine to prevent it, for one major reason: HIV, the human immunodeficiency virus that causes the disease, is a sloppy housekeeper when it comes to tending its genetic endowment. Every time HIV replicates, it makes mistakes, at least one error per generation of the virus. Within a few generations, it can begin to take on subtly different characteristics.

African American women in six U.S. cities are becoming infected with HIV at a rate five times the national average for black women, and closer to the rates of some African countries, according to a new study. Researchers at Johns Hopkins University and around the country who made the findings suspected the rates were relatively high in these "hot spots" that have battled the epidemic for decades, but the numbers still came as a surprise in a field that tends to focus more on black and gay men. The researchers found that in Baltimore; Atlanta; Newark, N.J.; New York City; Raleigh-Durham, N.C.; and Washington, the annual rate of infection was 24 per 10,000 black women.

A new virus that appears to have similarities to the AIDS virus has been isolated from a patient with Sjogren's syndrome, an uncommon ailment that causes dryness of the mouth and eyes, according to researchers at Tulane University School of Medicine in New Orleans.

This week, an additional two groups are reporting they were unable to find any evidence of XMRV, a retrovirus, in various groups of people, including those diagnosed with chronic fatigue syndrome. The pair of studies, published online in the Journal of Infectious Diseases , come a year after a team of scientists led by Judy Mikovits of the Whittemore Peterson Institute for Neuro-Immune Disease reported finding evidence of the retrovirus far more often in people diagnosed with chronic fatigue syndrome than in their healthy peers.

Government scientists have developed an unusual new form of gene therapy to treat inoperable brain tumors and plan to begin human trials this summer. The new approach, which has cured brain tumors in rats, takes advantage of the fact that brain cells do not normally divide and multiply, while tumor cells multiply rapidly. Researchers at the National Cancer Institute injected the tumors with mouse cells containing a specially modified virus that infects only dividing cells.
