Researchers at the La Jolla Institute for Allergy & Immunology have shown that cytomegalovirus (CMV) in the salivary glands can be reduced - and in some cases eliminated - through the use of antibodies to enhance the disease-fighting power of the immune system.

For a growing number of women in rural Mexico - and around the world - marital sex represents their single greatest risk for HIV infection. According to a new Mailman School of Public Health Study, because marital infidelity by men is so deeply ingrained across many cultures, existing HIV prevention programs are putting a growing number of women at risk of developing the HIV virus.

A new joint study by UCLA and the Rand Corp. shows that more than half of children with an HIV-infected parent are not consistently in that parent's custody.

Researchers from Massachusetts General Hospital (MGH) have found that infection with HIV, the virus that causes AIDS, is also associated with increased risk of myocardial infarction or heart attack. While rates of several cardiovascular risk factors were also increased in study participants infected with HIV, the increased incidence of heart attack was beyond what could be explained by risk factor differences.

There is the unknown extent of the deadly new strain of tuberculosis in South Africa and the region. This problem is a cause for concern, an international health expert said Wednesday. Dr Fabio Scano, a TB expert from the World Health Organization in Geneva, has been sent to South Africa at the request of the government to assist with the outbreak of the extensively drug-resistant tuberculosis strain, or XDR-TB.

Rabies, a relentless, ancient scourge, may hold a key to defeating another implacable foe: HIV. Scientists at Jefferson Medical College in Philadelphia have used a drastically weakened rabies virus to ferry HIV-related proteins into animals, in essence, vaccinating them against an AIDS-like disease. The early evidence shows that the vaccine - which doesn't protect against infection - prevents development of disease.

Researchers at Rush University Medical Center have been selected to participate in a collaborative initiative to develop a simple, affordable and rapid test to measure the immune systems of people infected with HIV/AIDS in developing countries.
