Europe becoming complacent over HIV prevention
Rising levels of gonorrhoea and syphilis across western Europe since 1995 imply that complacency over HIV prevention efforts may have set in among individuals and some governments, argue researchers in this week's BMJ. Angus Nicoll and Francoise Hamers examined national trends in diagnosed HIV infections, gonorrhoea, and infectious syphilis from... view more... (2002-05-28)
Antiretroviral Therapy Effective In Reducing Mother-to-child HIV-1 Transmission When Started After Childbirth (p 1171)
Results of a study from Malawi in this week's issue of THE LANCET highlight how antiretroviral therapy targeted at babies soon after childbirth (because their mothers' HIV diagnosis was made around the time of delivery) is still effective in preventing vertical HIV-1 transmission from mothers to their children. Zidovudine and nevirapine have been... view more... (2003-10-08)
Many pregnant women avoid HIV screening in Africa
'Prevention is the best cure' is a common expression, but what happens if preventative measures are not used? A large proportion of pregnant Ugandan women are going out of their way not to be HIV tested, increasing the risk of mother-to-child transmission. view more (2009-11-20)
Breastfeeding now safer for infants of HIV-infected mothers
An antiretroviral drug already in widespread use in the developing world to prevent the transmission of HIV from infected mothers to their newborns during childbirth has also been found to substantially cut the risk of subsequent HIV transmission during breast-feeding. view more (2008-02-05)
How breastfeeding affects HIV transmission
Mother to child transmission of HIV accounts for a large proportion of HIV infections in children, with many infected as a result of breastfeeding, which requires transfer of the virus across mucosal barriers. view more (2005-10-21)
AIDS surpasses black death as deadliest disease in history
In terms of illness and death, AIDS is worse than the Black Death of the 14th century. Ninety five per cent of new infections of HIV are in the world's poor countries and heterosexual transmission is responsible for most of these, reports Peter Lamptey, in this week's BMJ. view more (2002-01-23)
The Role Of Sexually Transmitted Diseases, Malaria, And Tuberculosis On The Hiv-1/Aids Epidemic In Africa (p 2177)
The effect of HIV-1 on other infectious diseases in Africa is an increasing public health concern. In a review in this week's issue of THE LANCET, Elizabeth Corbett from the London School of Hygiene and Tropical Medicine, UK, and the Harare Biomedical Research and Training Institute, Zimbabwe, and colleagues describe the role that three major... view more...

Researchers link specific antibody presence to prevention of mother-to-baby HIV transmission
Exploring why some HIV-positive mothers transmit the virus in utero to their babies while others don't, researchers from the UCLA AIDS Institute and Los Alamos National Laboratory studied 38 infant-mother pairs in the UCLA arm of the Los Angeles Pediatric AIDS Consortium. view more (2006-07-12)
World aides series : advances in research in prevention of mother-to-child HIV-1 transmission
'Although substantial progress has been made in preventing mother-to-child HIV-1 transmission in the past decade, critical research questions remain. Two perinatal epidemics now exist. In more-developed countries, integration of prenatal HIV-1 counselling and testing programmes into an existing antenatal infrastructure, availability of effective... view more... (2000-06-22)
Re-awakening old genes to help in the fight against HIV
A new vaginal cream containing a reawakened protein could someday prevent the transmission of HIV. view more (2009-04-28)
Antiretroviral Therapy Around Childbirth Reduces Risk Of Mother-To-Child HIV-1 Transmission (pp 1168, 1178)
Antiretroviral therapy given to women before, during, and after childbirth could be beneficial in reducing mother-to-child HIV-1 transmission in the first few weeks after delivery, suggest authors of a study in this week's issue of THE LANCET. However, this short-term benefit could be compromised unless new interventions are identified to prevent... view more... (2002-04-04)
Preventing mother-to-child HIV transmission in low-income countries
Can HIV transmission in pregnancy in low income settings be prevented with round the clock rapid testing in labor? view more (2008-05-06)
Male circumcision for HIV prevention and more
Three clinical trials in Africa found that adult male circumcision reduced the risk of men acquiring HIV infection from heterosexual sex by 51-60%. view more (2007-07-24)
AFRICAN HIV-1 EPIDEMIC NOT CAUSED BY MORE INFECTIOUS VIRAL SUBTYPE (p 1149)
The explosive HIV-1 epidemic in sub-Saharan Africa is unlikely to be the result of a viral subtype with increased infectivity, according to the results of a study published in this week’s issue of THE LANCET. The HIV-1 epidemic in eastern and southern sub-Saharan Africa is mainly caused by HIV-1 subtypes A, C, and D, whereas those in the USA... view more... (2001-04-11)
Risk of HIV transmission highest early in infection
New evidence suggests that the risk of HIV transmission may be highest in the early stages of infection. According to a study published in the April 1 issue of The Journal of Infectious Diseases, now available online, early infection accounted for nearly half of all transmission occurrences in an HIV-infected population in the province of Quebec,... view more...

Virological evidence cannot prove transmission in HIV criminal cases
Virological evidence cannot prove transmission in HIV criminal cases, warn experts in this week's BMJ. view more (2007-09-07)
The release of new data from the HVTN 502 HIV vaccine study
The new analyses revealed today from the STEP HIV vaccine clinical trial are both disappointing and puzzling. At this time, the data offer no clear explanations as to why the vaccine showed no measurable efficacy or why among individuals with background immunity to the adenovirus vector, there were more HIV infections in the vaccinees as compared... view more...

Kenyan Study Could Help Other African Countries Improve Hiv Blood-transfusion Strategies (p 657)
A 1994 study which highlighted the problem of HIV-1 transmission from blood-transfusion programmes in Kenya-and resulted in positive government action-could help other African countries develop safer blood-transfusion strategies. Little support for blood-safety programmes has been provided to less-developed countries over the past decade. The... view more... (2001-08-22)
Researchers have discovered a gene that can block the spread of HIV
A team of researchers at the University of Alberta, including a scientist at the University of Pennsylvania, have discovered a gene that is able to block HIV, and thought to in turn prevent the onset of AIDS. view more (2008-02-29)
Unsafe injections rejected as major source of HIV infection in Africa (p 482)
A recent theory proposing that unsafe injections are a major cause of HIV-1 infection in sub-Saharan Africa is rejected by authors of an article in this week's issue of THE LANCET. During the past year, a group (D Gisselquist and colleagues) has argued that unsafe injections are a major mode of HIV-1 transmission in sub-Saharan Africa, with up to... view more... (2004-02-04)
