Mother-to-child HIV infections decreasing: UN

The U.N. Children’s Fund says it is alarmed about increasing HIV and AIDS rates among adolescents over the last seven years and is advocating an aggressive program that includes condom distribution and antiretroviral treatment.

In a more positive development, UNICEF found that mother-to-child transmission of the HIV virus has been dramatically reduced and estimated that some 850,000 cases were prevented in low- and middle-income countries.

Its 2013 Stocktaking Report on Children and AIDS released Friday said AIDS-related deaths among those aged 10 to 19 increased between 2005 and 2012 from 71,000 to 110,000. About 2.1 million adolescents were living with HIV in 2012.

Nearly 90 percent of children newly infected with HIV live in just 22 countries. All except one are in sub-Saharan Africa.

“If high-impact interventions are scaled up using an integrated approach, we can halve the number of new infections among adolescents by 2020,” said UNICEF Executive Director Anthony Lake. “It’s a matter of reaching the most vulnerable adolescents with effective programs – urgently.”

High-impact interventions include condoms, antiretroviral treatment, prevention of mother-to-child transmission, voluntary medical male circumcision, communications for behavior change and targeted approaches for at-risk and marginalized populations.

UNICEF found dramatic improvement in prevention of new HIV infections among infants. Some 260,000 children were newly infected with HIV in 2012, compared to 540,000 in 2005.

New, simplified life-long antiretroviral treatment known as Option B+ provides the opportunity to effectively treat women with HIV and to prevent the transmission of the virus to their babies during pregnancy, delivery, and through breastfeeding.

The treatment involves a daily one-pill regimen.

Some of the most remarkable successes were in sub-Saharan Africa. New infections among infants declined between 2009 and 2012 by 76 percent in Ghana, 58 percent in Namibia, 55 percent in Zimbabwe, 52 percent in Malawi and Botswana and 50 percent in Zambia and Ethiopia.

UNICEF said that globally, the number of AIDS-related deaths overall fell by 30 percent between 2005 and 2012

Number of adolescents with HIV jumps by one-third: UN

Geneva:  The number of adolescents infected by the HIV virus has jumped by one third over the past decade, the United Nation’s health agency said on Monday, blaming gaps in care programs.

“More than 2 million adolescents between the ages of 10 and 19 years are living with HIV,” marking a 33 per cent rise since 2001, the World Health Organization said.

“Many do not receive the care and support that they need to stay in good health and prevent transmission. In addition, millions more adolescents are at risk of infection,” it warned.

In the world’s most AIDS-affected region, sub-Saharan Africa, the majority of adolescents with the virus are girls who have had unprotected sex, sometimes under duress.

In addition, many of those born with the virus or infected at birth in sub-Saharan Africa are becoming adolescents.

In Asia, meanwhile, young drug-users were the worst affected.

The WHO said that the failure to provide proper adolescent-focused programs had also resulted in a 50-per cent increase in reported AIDS-related deaths in the age group from 2005 to 2012.

In 2005, 70,000 adolescents died of AIDS. Seven years later, the figure was 104,000.

That contrasted starkly with the 30-per cent decline in the general population, the WHO underlined.

The year 2005 marked the high point of global AIDS deaths, which hit 2.3 million. Last year, the toll was 1.6 million.

“Adolescent girls, young men who have sex with men, those who inject drugs or are subject to sexual coercion and abuse are at highest risk,” said Craig McClure, head of HIV programs at UN children’s agency UNICEF.

“They face many barriers, including harsh laws, inequalities, stigma and discrimination which prevent them from accessing services that could test, prevent, and treat HIV,” McClure added.

“About one-seventh of all new HIV infections occur during adolescence. Unless the barriers are removed, the dream of an AIDS-free generation will never be realised,” he insisted.

The data was issued as the WHO released its first adolescent-specific care guidelines ahead of World AIDS Day on December 1.

“Adolescents face difficult and often confusing emotional and social pressures as they grow from children into adults,” said Gottfried Hirnschall, head of the WHO’s HIV/AIDS Department.

“Adolescents need health services and support, tailored to their needs. They are less likely than adults to be tested for HIV and often need more support than adults to help them maintain care and to stick to treatment,” he added.

Among the measures needed, the WHO said, is an end to the requirement for parental permission to have an HIV test.

In sub-Saharan Africa, it is estimated that in the 15-24 age bracket, only 10 percent of young men and 15 percent of young women know their HIV status.

In other regions, although data are scarce, access to HIV testing and counseling by vulnerable adolescents is consistently reported as being very low, the WHO said.

Children at risk of AIDS should be tested at birth: UN

More than a quarter of a million children each year are born infected with the virus that causes AIDS, but too few are being tested early to receive treatment and prolong their lives, the United Nations said on Wednesday.

Michele Sidibe, executive director of UNAIDS, called for diagnostic kits to be improved for detection in babies of the Human Immunodeficiency Virus (HIV) that causes AIDS, and for their “still high” current price of $25-50 to be brought down.

Children are the “forgotten” victims of the AIDS epidemic, yet 260,000 babies joined their ranks last year, mainly in sub-Saharan Africa, he said.

“Irrespective of the market size we need to make sure that diagnostics are made available for children,” he told a news conference in Geneva ahead of World AIDS Day on December 1.

“We made a lot of progress during the last 2-3 years in terms of treatment, in terms of medicines, in terms of making sure that the molecules are more well-targeted for children. But where we are failing is also making early diagnostics.”

U.S.-based Abbott Laboratories and Swiss drugmaker Roche are among the main manufacturers of HIV diagnostics, according to senior UNAIDS officials.

Some 3.3 million children under age 15 have HIV, but only 1.9 million of them require treatment today, according to the Geneva-based agency. Fewer than 650,000 or 34 percent of the 1.9 million received antiretroviral AIDS drugs in 2012, still a rise of 14 percent from the year before, it said.

Some 14 million adults with HIV need treatment, and 9 million of them or 64 percent are receiving it, a far higher coverage rate than for children.

UN AIDS has identified 22 priority countries for stopping infections in children, 21 of them in sub-Saharan Africa, home to 90 percent of women living with HIV. The other is India.

In three of these priority countries – Chad, Democratic Republic of Congo and Malawi – fewer than 5 percent of infants at risk are being tested for HIV at birth, UNAIDS says.

“In priority countries, only 3 in 10 children receive HIV treatment. We have seen tremendous political commitment and results to reduce mother-to-child transmission but we are failing the children who become infected,” said Sidibe, who is from Mali.

All children under five who test positive for the virus should be put on treatment, according to Mahesh Mahalingam, UNAIDS director for its global plan for stopping new infections in children.

Current PCR tests are able to detect the virus in a baby only after the age of six weeks and require sending a blood sample to a specialized laboratory, he said.

“What we looking for are easier tests that we can administer earlier on, this will help detect the virus and start them on medicines faster. We recommend that as soon as the child is known to be HIV positive, you start on anti-retroviral drugs,” Mahalingam said.

He added: “The earlier we can diagnose, the earlier we can treat them which increase chances of child survival. Children are now getting to grow into adults. If we start pretty early they have the same chance of living as any other children.”
